If you happen to be a professional working in the Information Technology (IT) industry, you would be aware of the intensely competitive nature of the industry and the constant need it imposes on an IT professional to upgrade skill sets as technology evolves. You may have felt the need to conquer a new technology or upgrade your existing skill set or just to see where you stand among your peers. If this is the case, it is time to explore the advantages that acquiring an IT certification can provide.

Here are seven most sought-after IT certifications in no particular order:

- CompTIA Security+ – This is a certification for IT professionals with at least two-years of industry experience. It is not vendor-specific and is a test of the professional’s knowledge of the fundamentals of security.

-Cisco CCIE/CCNA – This is a certification provided by Cisco Systems for networking professionals. The CCIE is a comprehensive certification for experts, and the CCNA is meant to improve the skills of those with some experience.

-CompTIA A+ – This is tailored for validating the expertise in hardware and can be a valuable certification for computer-related maintenance and support professionals.

-Microsoft MCITP – MCITP stands for Microsoft Certified IT Professional and is a prestigious one meant for professionals in database, enterprise and server administration. This new certification offered by Microsoft assesses an individual’s capability in meeting the demands of common job roles in the IT industry.

-Microsoft MCSE/MCSA – MCSE (Microsoft Certified Systems Engineer) and MCSA (Microsoft Certified Systems Administrator) are two of the earliest certifications offered by Microsoft that still command respect in the industry. Both certifications demand a certain level of experience and involve a number of grueling examinations.

-Microsoft MCA – MCA (Microsoft Certified Architect) is a certification open to professionals who have a minimum of three years of experience on advanced IT architecture. This is a peer-evaluated certification and is awarded to very few of the aspirants. Obtaining this is considered an achievement in itself and is rated highly in the industry.

-RHCE/RHCA – With the proliferation of Linux based systems, there is a great demand for certified Linux professionals and RHCE (Red Hat Certified Engineer) and RHCA (Red Hat Certified Administrator) are two certifications awarded by Red Hat Inc.; one of the prominent distributors of Linux Operating Systems.

It’s a Microsoft Certified Systems Engineer’s job to design and create business platforms on Windows server systems. Certified professionals working with Microsoft platforms have access to an assortment of online tools, ranging from official logos to transcripts. Most importantly, they can have access to their very own landing page hosted by Microsoft. In order to get started with this rewarding occupation, however, they’ll have to study a good MCSE training course.

A good MCSE CBT course can help students prepare before examination time. The exams, especially the core ones, consist of questions about Windows, operating systems, networking, and so forth. The total examination, needless to say, can be quite long. As such, students need to prepare a great deal before taking the examination. They can do by taking a MCSE training course.

Fortunately, while long, the test really isn’t that hard, just as long as the students familiarize themselves with Microsoft Certified Systems. There are also free MCSE practice tests, tips, resources, notes, and more—online. These free resources along with MCSE CBT courses give students all the knowledge they need for passing the examination and receiving their MCSE certifications.

Networking and interacting with one another as well as professionals is a great way for students to receive help and advice. The internet is filled with forums and blogs for which beginners can ask for advice from Microsoft Certified professionals. Beginners need to ask for recommendations in the first place before selecting MCSE training course.

Some of the courses are a waste of time and money, since students don’t learn a thing with them and end up failing the examination. Some MCSE CBT courses and online classes, however, are well worthwhile and very comprehensive. They don’t have to be expensive, either. In fact, some companies will even pay for their employee’s computer based training and certification. The ones who don’t have that luxury, though, need to make sure they find a course that is affordable, but not cheap. They can then get started on the MCSE training course and, if all goes well, pass the examination that will make them a Microsoft Certified System’s Engineer!

Overview

Red Hat Certified Engineer (RHCE) is a performance-based test that measures actual competency on live systems. Called the “crown jewel of Linux certifications,” RHCE proves an individual’s ability to configure networking services and security on servers running a Red Hat OS. RHCE was recently named the hottest certification in all of IT by CertCities.com.

The RHCE Exam

Becoming a Red Hat Certified Engineer requires passing a five-and-a-half-hour hands-on exam. There are four different approaches to preparing for the exam depending on your existing level of Linux expertise.

Level of Linux Expertise

To determine your level of experience, take our pre-assessment questionnaires or read the descriptions below for the Standard and Rapid Tracks.

Candidates have the option of gaining the certification by passing two tests (ICND1 640-822 and ICND2 640-816), or one single test (CCNA 640-802); the two-test option has the advantage of allowing the candidate to focus on certain subjects.

The certification is valid for three years; at that time a CCNA holder must either

* re-take the CCNA or ICND exam, or
* take and pass an exam for one of the Professional or Specialist level certifications (excluding the sales specialist exams), or pass the CCIE written exam.

These exams are known by their corresponding numbers. When the curriculum of the exam changes the exam number also changes. The current exam number for CCNA is 640-802. New ICND Part1 (640-822 ICND1) and ICND Part2 (640-816 ICND2) available from 15 Aug 2007.

These exams are conducted by authorized test centers at a cost of $125 each for the INTRO or ICND exams and $150 for the full CCNA exam.

There is also the Cisco Networking Academy, which brings the CCNA and CCNP curricula into traditional educational institutions in over 150 countries.Students enrolled in Cisco Networking Academy can request exam vouchers that allow them to take the retired exam for an extended period of time.

Microsoft Certified Systems Engineer (or MCSE) is the best-known and premiere Microsoft certification. It qualifies an individual as being able to analyze the business requirements for information systems solutions, and design and implement the infrastructure required.

Microsoft’s MCSD (Microsoft Certified Solution Developer) is a high-level certification for advanced developers who design and develop leading-edge enterprise solutions, using Microsoft development tools and technologies as well as the Microsoft .NET Framework. The MCSD builds on the more entry-level MCAD (Microsoft Certified Application Developer) certification by encompassing not only development, testing, deployment and maintenance, but also analysis and design.

The MCSD for Microsoft .NET got its start back in the summer of 2002. Prior to that, the MCSD was based on Visual Studio 6 technologies and was sometimes referred to as the MCSD on Windows 2000. The .NET MCSD certification does not retire but newer versions of it may be released as technology changes. There are no specific prerequisites for the MCSD, although Microsoft recommends that you have two years of experience developing and maintaining solutions and applications. As soon as candidates pass their first qualifying exam for the MCSD program, they achieve a Microsoft Certified Professional (MCP) certification. Moreover, a candidate that is working towards the MCSD will achieve the MCAD certification along the way. To achieve the MCSD, a candidate must pass a total of five exams: four core and one elective.

With .NET, Microsoft is also espousing a vision, this time about how the Internet can make businesses more efficient and deliver services to consumers. The present enterprise setup’s need to have n-tier architecture with diverse platforms and object models communicating with each other. The present applications are to be created such that those applications have to run in any platform (like Windows, Linux, Mac, Unix etc) and which consist of components written in many programming languages and object models.

Many language vendors have tried to upgrade their languages, but there is a limit to which they have been successful since they have to maintain backward capability and face many other problems too. To solve the problem of the current programmers Microsoft has come with a very promising solution “The .NET Platform”.

.NET provides a number of benefits that will make developers more productive, reduce the number of bugs, speed application development, and simplify deployment. IT managers are understandably wary, since .NET is a new technology that requires a moderately steep learning curve. For most organizations, however, the benefits will far outweigh the negatives; and with .NET, you’ll see great productivity gains for future development projects.

.NET certification is the premier credential for professionals who design and develop leading-edge business solutions with Microsoft .NET development tools, technologies and platforms.

You might want to consider taking the MCSD 70-316 exam to:
