When you're choosing which computer certification to pursue next, you should also be formulating a plan for your career. Your time is precious, and you should never choose to pursue a certification because it's "hot". There are some hard questions you should ask yourself before deciding to pursue the CCNA, CCNP, CCVP, CCSP, CCIE, MSCE, or any of the many other vendor certifications that are out there.
Why do I want this certification?
This is the biggest and most important question you should answer before you spend a dime on books or classes.
If your primary goal in earning a certification is the money you feel companies will throw at you after you get it, make sure to do your research first. Basing your certification pursuits on a salary survey can lead to some serious frustration on your part. Don't get me wrong, I like money. J But those surveys can be very misleading. There's really no such thing as an "average" salary in IT. Job responsibilities and requirements vary greatly from company to company, to the point where a "network admin" may make $25K at one job and $75K at another. You can see where such variations in pay can lead to some misleading statistics. (And if you're thinking of attending a tech school whose main pitch is "look at all the money this cert can get you", ask a lot of questions about how they arrived at this amount.)
A positive answer to this question works wonders. If you have a plan for your career, you'll know how this certification can fit into your plans. If you don't know what you're going to do with it when you get it, or worse, don't have a plan for your future, you may be wasting your time. Ask yourself the hard questions now - you won't regret it.
How does the vendor protect my investment of time and money?
Let's face it: earning your certification costs time and money. You've got to set time aside to study, you'll need books, perhaps a class, etc. If you're spending that money and time, it should be to make yourself more valuable in the workplace.
The vendor should also have a vested interest in keeping your certification valuable. Take Cisco, for instance. I was at a bit of a career crossroads a few years ago. Should I pursue my masters degree, or pursue the CCIE? I took a strong look at both choices, and I knew that Cisco works endlessly and tirelessly to protect the value of their certifications. While other major vendors have made strides to do so, I felt Cisco did the best job of protecting the value of their certifications. That's why I felt secure in the investment of my finances and time into a major Cisco certification, and I've never made a better decision.
Before making a major investment into a computer certification, consider the steps that a vendor does or does not make to protect your investment.
Computer certifications have helped me tremendously in building my IT career. By asking the right questions, and taking a hard look at your motives and plans before pursuing a given certification, they can do the same for you.

A certification is one of the most valuable weapons in your job-hunting arsenal. A college degree and some experience -- and maybe a brother-in-law who's the hiring manager -- doesn't hurt either. But companies eager to hire specialists turn to certified candidates, in hopes that those candidates will be able to hit the ground running, and will require no training period. Although a bachelor's degree in computer science is always a plus, it doesn't necessarily prove that you know how to run a Microsoft network. An MCSE does.
The most popular certifications, by far, are those from Microsoft and Cisco, but hundreds of designations are available for every conceivable specialty. For a comprehensive listing of certifications, consult Anne Martinez's book, Get Certified & Get Ahead (McGraw-Hill).
"In IT certification, what you're going to get is some immediate bang for your buck in terms of salary increase," said Amit Yoran, CEO of information security provider Riptech and adjunct professor at George Washington University. However, Yoran still stresses the importance of having a college degree to accompany the certification.
Why certify? Doug Kendzierski, associate vice provost at the University of Maryland, Baltimore County (UMBC), said, "We're in a market in which demand has never outpaced supply by such a tremendous disparity." Certification is a way to prove to a potential employer that you have a specific set of skills, thereby making their hiring decision a little bit easier.
What's the hottest certification?
"Two areas of focus I see as very attractive is any sort of networking-based technologies, and the other is software engineering disciplines," said Yoran. Beyond the most common certifications (Microsoft, Cisco, Novell), though, there are plenty of other designations that may be just as valuable. If you want a career in Linux, get the RHCE (Red Hat Certified Engineer) certification. If you want to cash in on the increasing concern over network security, the SANS GIAC (System Administration, Networking, and Security Global Incident Analysis Center) certificate will show potential employers that you can protect the corporate goodies. To gain even more leverage, combine this vendor-neutral security certification with a vendor-specific one. Almost every firewall-equipment vendor has its own certification program, and a generic security certification combined with a CCSE (Check Point Certified Security Engineer) or a Cisco Security Specialist certificate would make for a quick path to employment.
Of course, the venerable MCSE still carries a lot of weight, perhaps more than ever since Microsoft made the test more scenario-based and less theoretical. The test is definitely more difficult, but that makes it more valuable in the marketplace. According to Mike Smith, senior product marketing manager for IT training and courseware development company Wave Technologies International, "They don't just say, 'Here, answer this question.' Microsoft has case studies, where they say, 'Here's a scenario, read these three pages and answer these seven questions.' They'll give you a diagram of pieces to a network puzzle and say, 'Put this together, tell me where your routers go, where your servers go, where your desktops are going to be and tell me the flow of your cabling.' You're not going to come up with that on your own."
Vendor-specific or vendor-neutral?
"If you take a networking essentials exam, you don't learn networking essentials, you learn Microsoft's view of networking essentials," said Yoran. This is a useful approach if you are going to run a Microsoft network, but according to Yoran, "the academic approach is a much purer one." If you have a vendor-specific certification, you understand a specific piece of proprietary technology, and that is often what employers want. But in the long run, confining yourself to a single vendor-specific certification may limit your advancement options. "You're taking a near-term gain with a long-term detriment," said Yoran.
Combining a vendor-specific certification with a vendor-neutral one will expand your horizons and position your value beyond a specific piece of technology. "Somebody who is just starting out has no choice but to start at a vendor-neutral platform," said Kendzierski, "because what they need is a full survey of technology that is not rooted in a particular product." You should pursue a certification in a specific vendor's technology after you get that theoretical background, either through a vendor-neutral certification or college education.
The cost factor
You can easily spend thousands -- even tens of thousands -- of dollars on a combined training/certification program, although the testing alone usually only costs a couple hundred. The best deal is still http://www.brainbench.com/xml/bb/homepage.xml target=new>Brainbench, a Web-based testing center that offers certificates for just about anything you can think of and is well-known and respected throughout the IT industry. Some tests are still available for free, but most cost $19.95.

IT certifications boast numerous benefits. They bolster resumes, encourage higher salaries, and assist in job retention. But which IT certifications are best?
Technology professionals generate much debate over just that question. Many claim vendor-specific programs best measure a candidate’s skills, while others propose vendor-independent exams are the only worthy way of measuring real-world expertise. Still other observers believe the highest-level accreditations — Microsoft’s MCSE or new Architect Series certification, Cisco’s CCIE, etc. — are the only credentials that truly hold value.
Myself, I don’t fully subscribe to any of those mindsets. The best IT certification for you, after all, is likely to be different from that for another technology professional with different education, skills, and goals working at a different company in a different industry. For that reason, when pursuing any professional accreditation, you should give much thought and care to your education, experience, skills, goals, and desired career path.
Once a career road map is in place, selecting a potential certification path becomes much easier. And that’s where this list of the industry’s 10 best IT certifications comes into play. While this list may not include the 10 best accreditations for you, it does catalog 10 IT certifications that possess significant value for a wide range of technology professionals.
Note: This information is also available as a PDF download.
The new-generation Microsoft Certified IT Professional credential, or MCITP for short, is likely to become the next big Microsoft certification. Available for a variety of fields of expertise — including database developer, database administrator, enterprise messaging administrator, and server administrator — an MCITP validates a professional’s proven job-role capabilities. Candidates must pass several Microsoft exams that track directly to their job role before earning the new designation.
As with Microsoft’s other new-generation accreditations, the MCITP certification will retire when Microsoft suspends mainstream support for the platforms targeted within the MCITP exams. By matching the new certification to popular job roles, as has been done to some extent with CompTIA’s Server+ (server administrator), Project+ (project manager), and A+ (desktop support) certifications, Microsoft has created a new certification that’s certain to prove timely, relevant, and valuable.
The new-generation Microsoft Certified Technology Specialist (MCTS) helps IT staff validate skills in installing, maintaining, and troubleshooting a specific Microsoft technology. The MCTS certifications are designed to communicate the skills and expertise a holder possesses on a specific platform.
For example, candidates won’t earn an MCTS on SQL Server 2008. Instead, they’ll earn an MCTS covering SQL Server business intelligence (MCTS: SQL Server 2008 Business Intelligence), database creation (MCTS: SQL Server 2008, Database Development), or SQL server administration (MCTS: SQL Server 2008, Implementation and Maintenance).
These new certifications require passing multiple, tightly targeted exams that focus on specific responsibilities on specific platforms. MCTS designations will expire when Microsoft suspends mainstream support for the corresponding platform. These changes, as with other new-generation Microsoft certifications, add value to the accreditation.
Security continues to be a critical topic. That’s not going to change. In fact, its importance is only going to grow. One of the quickest ways to lose shareholder value, client confidence, and sales is to suffer a data breach. And no self-respecting technology professional wants to be responsible for such a breach.
CompTIA’s Security+ accreditation provides a respected, vendor-neutral foundation for industry staff (with at least two years of experience) seeking to demonstrate proficiency with security fundamentals. While the Security+ accreditation consists of just a single exam, it could be argued that any IT employee charged with managing client data or other sensitive information should, at a minimum, possess this accreditation. The importance of ensuring staff are properly educated as to systems security, network infrastructure, access control, auditing, and organizational security principles is simply too important to take for granted.
There’s more to information technology than just administration, support, and networking. Someone must create and maintain the applications and programs that power organizations. That’s where the new-generation Microsoft Certified Professional Developer (MCPD) credential comes into play.
The MCPD accreditation measures a developer’s ability to build and maintain software solutions using Visual Studio 2008 and Microsoft .NET Framework 3.5. Split into three certification paths (Windows Developer 3.5, ASP.NET Developer 3.5, and Enterprise Applications Developer 3.5), the credential targets IT professionals tasked with designing, optimizing, and operating those Microsoft technologies to fulfill business needs.
A redesigned certification aimed at better-measuring real-world skills and expertise, the MCPD will prove important for developers and programmers. Besides requiring candidates to pass several exams, the MCPD certification will retire when Microsoft suspends mainstream support for the corresponding platform. The change is designed to ensure the MCPD certification remains relevant, which is certain to further increase its value.
The Cisco Certified Internetwork Expert (CCIE) accreditation captures most of the networking company’s certification glory. But the Cisco Certified Network Associate (CCNA) might prove more realistic within many organizations.
In a world in which Microsoft and Linux administrators are also often expected to be networking experts, many companies don’t have the budgets necessary to train (or employ) a CCIE. But even small and midsize corporations can benefit from having their technology professionals earn basic proficiency administering Cisco equipment, as demonstrated by earning a CCNA accreditation.
As smaller companies become increasingly dependent upon remote access technologies, basic Cisco systems skills are bound to become more important. Although many smaller organizations will never have the complexity or workload necessary to keep a CCIE busy, Cisco’s CCNA is a strong accreditation for technology professionals with a few years’ experience seeking to grow and improve their networking skills.
Technology professionals with solid hardware and support skills are becoming tougher to find. There’s not much glory in digging elbow-deep into a desktop box or troubleshooting Windows boot errors. But those skills are essential to keeping companies running.
Adding CompTIA’s A+ certification to a resume tells hiring managers and department heads that you have proven support expertise. Whether an organization requires desktop installation, problem diagnosis, preventive maintenance, or computer or network error troubleshooting, many organizations have found A+-certified technicians to be more productive than their noncertified counterparts.
Changes to the A+ certification, which requires passing multiple exams, are aimed at keeping the popular credential relevant. Basic prerequisite requirements are now followed by testing that covers specific fields of expertise (such as IT, remote support, or depot technician). The accreditation is aimed at those working in desktop support, on help desks, and in the field, and while many of these staffers are new to the industry, the importance of an A+ certification should not be overlooked.
Some accreditations gain value by targeting specific skills and expertise. The Project Management Professional (PMP) certification is a great example.
The Project Management Institute (PMI), a nonprofit organization that serves as a leading membership association for project management practitioners, maintains the PMP exam. The certification measures a candidate’s project management expertise by validating skills and knowledge required to plan, execute, budget, and lead a technology project. Eligible candidates must have five years of project management experience or three years of project management experience and 35 hours of related education.
As organizations battle tough economic conditions, having proven project scheduling, budgeting, and management skills will only grow in importance. The PMI’s PMP credential is a perfect conduit for demonstrating that expertise on a resume.
Even years after their introduction, Microsoft Certified Systems Engineer (MCSE) and Microsoft Certified Systems Administrator (MCSA) credentials remain valuable. But it’s important to avoid interpreting these accreditations as meaning the holders are all-knowing gurus, as that’s usually untrue.
In my mind, the MCSE and MCSA hold value because they demonstrate the holder’s capacity to complete a long and comprehensive education, training, and certification program requiring intensive study. Further, these certifications validate a wide range of relevant expertise (from client and server administration to security issues) on specific, widely used platforms.
Also important is the fact that these certifications tend to indicate holders have been working within the technology field for a long time. There’s no substitute for actual hands-on experience. Many MCSEs and MCSAs hold their certifications on Windows 2000 or Windows Server 2003 platforms, meaning they’ve been working within the industry for many years. While these certifications will be replaced by Microsoft’s new-generation credentials, they remain an important measure of foundational skills on Windows platforms.
As mentioned with the Security+ accreditation earlier, security is only going to grow in importance. Whatever an organization’s mission, product, or service, security is paramount.
(ISC)², which administers the Certified Information Systems Security Professional (CISSP) accreditation, has done well building a respected, vendor-neutral security certification. Designed for industry pros with at least five years of full-time experience, and accredited by the American National Standards Institute (ANSI), the CISSP is internationally recognized for validating a candidate’s expertise with operations and network and physical security, as well as their ability to manage risk and understand legal compliance responsibilities and other security-related elements.
While pursuing my first Microsoft certification 10 years ago, I remember debating the importance of Linux with several telecommunications technicians. They mocked the investment I was making in learning Microsoft technologies. These techs were confident Linux was going to displace Windows.
Well, didn’t happen. Linux continues to make inroads, though. The open source alternative is an important platform. Those professionals who have Linux expertise and want to formalize that skill set will do well adding CompTIA’s Linux+ certification to their resumes.
The vendor-neutral exam, which validates basic Linux client and server skills, is designed for professionals with at least six to 12 months of hands-on Linux experience. In addition to being vendor-neutral, the exam is also distribution neutral (meaning the skills it covers work well whether a candidate is administering Red Hat, SUSE, or Ubuntu systems).
Technology professionals almost always have strong reactions when debating certification’s value. Listing the top 10 certifications leaves room, of course, for only 10 credentials. That means many favorite and popular designations, such as HIPAA and Sarbanes-Oxley (SOX) certifications, have been necessarily omitted. Other important accreditations, including those for VoIP providers and from PC manufacturers, Red Hat, and even Apple, have also been left out here.

Load balancing also referred to as load sharing gives the network the ability to use the bandwidth which is available on links which would have been only used in the event of the primary link failing.
Another use of Load balancing is much faster convergence since there are multiple routes in the routing table with the same prefix, in actual fact the convergence time in testing has been shown to be essentially instant.
As an example imagine we have a branch router with two routes to towards the headquarters prefix, if one of the routes was to fail EIGRP would not need to look for a Feasible successor in the topology nor will it go active on the route since the other route is already in the routing table. (For the record EIGRP will only look in the topology table or go active on a route if a prefix to the network does not exist in the routing table)
Enabling load balancing in EIGRP is quite simple and requires only two commands, the first of these commands is configured under the EIGRP path:
Router(conf-router)#maximum-path number
This command is defaulted to 4 paths which is generally seen as big enough since most networks would not have more than 4 possible paths.
The second command to configuring EIGRP load balancing is the variance command. The variance command gives you control of an operation known as a "multiplier". This multiplier allows you to get around the problem of EIGRP's rather large metric. Consider a network with 2 or more paths through the network to a common destination, the chances of EIGRP's metric being identical for all the routes is unlikely due to the fact that EIGRP uses such an unwieldy metric.
With the variance command you can instruct EIGRP to consider Feasible Successors as viable routes to be placed into the routing table along side the Successor route.
The variance is a multiplier which allows you to tell the EIGRP process to consider Feasible Successors which have Feasible Distances that fall within the value of the multiplier.
The way the variance works is you set the multiplier as a number between 1 and 128. The EIGRP process will then multiply the Successor's route Feasible Distance by the value of the variance multiplier and any Feasible Successors whose Feasible Distance is less than the result of the variance multiplied by the Feasible distance will be placed into the routing table and treated as equal to the original route. The number of routes that can be placed into the routing table for the same prefix length is the value set by the "maximum-path" command which as you'll recall is 4.
One point to always bear in mind is that unless a route in the topology table the path cannot be used to load balance across. For the route to make it into the topology table the Advertised distance of the route must be less than the Feasible Distance of the Successor route.
Traffic is load balanced across the path proportionally according to the route metrics with more traffic being sent across the lower metric paths, or the router will send all the traffic across the best metric path and leaving the other path in active standby in the event the primary path fails.

Computer Engineering (CE) lets in design, execution, maintenance, and construction of computers and computer checked equipment. It's an interdisciplinary class, which integrates both Electrical Engineering (EE) and Computer Science discipline. Computer Engineering knowledge programs let in subjects on computer hardware and software.
There are a lot of college that offer CE either as a degree curriculum or as a sub-subject of EE. Some of the outstanding CE courses add education on the power, digital and electronics systems. They cover disciplines that let in digital logical system circuits, computer and communication systems, and electro-optics microprocessors. Others admit micro-coding, logic circuits, digital prototype processing, machine vision and lasers.
Studies in CE are studied to make and operate hardware and software for computers applied in daily life as well as the super-computers, applied by engineering. The engineering apply them to dissolve advanced and multiplex problems associated their analyzes. Computer engineering knowledge also allows information on computer network, and web computation.
There are postgraduate and graduate courses of study such as MSC or Master of Science and PHD CE programs. Scholars study programming, computer architecture, digital designing, and integrated systems Studies, in the bachelor course of study. In the postgraduate courses of study students study progressive Studies in logic designing, computer architecture, hardware design and computer arithmetic languages. They also study media processing,multiprocessor systems, and advanced system designing.
CE knowledge develops the students to begin their personal companies. Instead of studying how the hardware and software runs, students also study to really design and program computers. Web has allowed an choice to follow the class of CE online.
Referable the general use and consolidation of computers into daily life, it's difficult to divide the subjects of EE and Computer Engineering.
They're complement and connected one another as branches of knowledge.

As a CCNA/CCNP candidate you are expected to understand the purpose and function of Spanning-tree Portfast. The CCNA/CCNP's exam will ask of you to determine the purpose of the Portfast within the spanning-tree protocol.
Before we go into the detail for the purpose and operation of the Portfast feature we need to understand the switched network environment behaviour before the introduction of portfast as a command..
From the "BPDU Guard" article you will recall that the stability of the Root Bridge is of paramount importance in the operation and continual uninterrupted service of spanning-tree and that a change in the position of the Root Bridge will cause service disruption on the network; another important factor to bear in mind is that is it not just the changing of the position of the Root Bridge that can cause network disruption but events such as access switchports transitioning on/off line can create an unstable network.
When a port first goes on-line spanning-tree will treat it like it treats any other port and will cycle through the normal spanning-tree port roles, i.e. blocking, listening. Learning, forwarding. The port will transition to the forwarding state after 30secs. In which no user traffic is allowed to pass.
At the point that the port went on-line the switch would have generated a new type of Bridge Protocol data unit called a "Topology Change Notification" BPDU, this TCN is relayed up out of the Root port towards the Root Bridge, the Root Bridge will register this TCN as a "Topology Change" and reset the TCN timer. These timers can be viewed by issuing the "show spanning-tree vlan # detail". These false readings will cause no end of confusion in your fault finding and network disruption as you chase false positives.
The major benefit of Portfast on the access port, (since this command can only an should only be configured in access ports) is that it causes spanning-tree to bypass the lengthy forward delay timers on that port.
Port fast is enabled on an access port:
Swith(config-if)#spanning-tree portfast
Once PortFast is enabled it place the port directly into the forwarding state, bypassing the spanning-tree forward delay timers, but at the same time the PortFast feature will keep an eye open for any BPDU's entering the access ports. If at any time the port received a BPDU it will default back to normal operation.
With the Portfast feature on the port the switch does not generate any more TCN's when the port transitions on/off line, this means that any "Topology Changes" that you view from the output of the "show spanning-tree detail" you will see valid TCN's along with the port that the TCN was received on.

BPDUGuard
As a CCNA / CCNP candidate you are expected to understand the purpose and function of Spanning-tree BPDU guard. The CCNA / CCNP's exam will ask of you to determine the purpose of the BPDUGuard (Bridge Protocol Data Unit) within the spanning-tree protocol.
Before we go into detail as to the purpose of the BPDU Guard feature a quick recap on the spanning-tree protocol is required.
Spanning-tree is a protocol which is designed to prevent physical and/or logical loops in your layer 2 network. Spanning-tree achieves this loop free environment by first of all electing a device to act as the focal point of the network which all other switches measure themselves from. This focal point role is an elected role. The election of the focal point known as the "Root Bridge" is done at the very start of spanning-tree determining the loop free topology, the election of the Root Bridge is carried out by using a combination of the switches MAC address and a value known as the "Default Priority".
These two values are conveyed into the network via BPDU's. BPDU's are used by spanning-tree to maintain a stable state network. In standard 802.1D spanning-tree for instance only the Root Bridge generated a BPDU.
The stability of the Root Bridge is of paramount importance in the operation and continual uninterrupted service of spanning-tree. A change in the position of the Root Bridge will cause service disruption on the network with data and voice session timing out.
It is important to consider what events could cause a change in the position of the Root Bridge, events such as links failing between the existing Root Bridge and the rest of the network would cause a change, or possibly a duplex mismatch between the Root Bridge and downstream switches causing the spanning-tree messages from the Root Bridge from reaching the other parts of the network. These events are easily fixed and resolved none of which would require the use of the BPDU Guard feature.
In our network we want to enforce the Spanning-tree domain borders and keep our active topology and the position of our Root Bridge predictable.
In our network we enable BPDU Guard only on access ports (access ports lead to end user devices) so that any end user devices on these ports that have BPDU Guard enabled are not able to influence the Spanning-tree topology.
BPDU Guard is enabled on an access port:
Swith(config-if)#spanning-tree bpduguard enable
Once BPDU Guard is enabled it will keep an eye open for any BPDU's entering the access ports. The only devices which can reliably create and transmit BPDU's are switches.
We want to keep a predictable topology and not allow other switches outside our control onto our network. If a rogue switch is introduced into our topology it will in most cases transmit a BPDU, if the rogue switch has "better" values than the existing Root Bridge it will cause a topology change in the switched network. Any topology change is bad news for the users.
By configuring the "BPDU Guard" feature on the access-ports enables the spanning-tree protocol to shut the port down in the event that is receives a BPDU. As a rule of thumb, BPDU's are really only expected across trunk links.
If a rogue switch is plugged into a port configured for BPDU Guard, the port will disable as soon as the first BPDU is received, by shutting the port down we prevent the rogue switch from affecting our spanning-tree topology.
To re-enable a port disabled by BDPU Guard you will need to remove the offending device and then bounce the port by issuing the shut/no shut command.

Everyone wants to attract in his or hers company people able to implement effective business solutions and everybody is willing to pay them more money in order to keep them there.
A job opportunity after SAP course is definitely a possibility in companies using ERP software. However, attending such a course does not turn you into an expert in a certain field. It enhances your exiting abilities and it teaches you how to maximize the work you were already doing or the work you have been prepared to do in your school years. An SAP course in itself is not going to get you a job unless it is backed up by specific knowledge and experience in a certain area.
Some consider a job opportunity after SAP course the possibility of developing a career as an SAP consultant. Lots of companies are introducing ERP software in their activity and are looking for a person capable of offering them the necessary guidance and help in implementing it. Getting an SAP certification can open unexpected career opportunities because it allows you to combine planning and execution in a manner that can only be in the best interest of the company.
Benefiting of a job opportunity after SAP course is nothing difficult, especially for someone already a professional in his or hers field of activity. SAP courses are available to be attended by anyone interested in expanding their horizons. Getting certified after finishing the course is also simple and it would be a shame not to take advantage of all the perspectives that the certification can open in your professional life.
