In today's arena, Linux has the biggest user base, similar to how Microsoft dominates on our desktops. It goes without saying that over the years, Linux has increased its dominance aggressively. Presently, there is a growing demand for Linux skilled professionals, who really enjoy better services, like higher pay packs, career boosts and value in the organization etc.

IT is considered as the most important Linux distribution. Linux certification holders are equipped with the knowledge that involves troubleshooting, system administration and installation. To retain and develop their own professional standards, Linux certifications are challenging but with the correct preparation for the certification exams and proper Red Hat hands-on trainings, one may easily pass the exams.

Linux, undoubtedly has much advantage over some of the other leading operating systems, when it comes to IT security sphere, it becomes more prominent. Because of these sharp and well tuned security features, among the other prominent features, many Government and Military agencies has jumped on the Linux and Linux technologies quite early.

Linux training has been growing tremendously over the years; many organizations are providing on-site training classes for groups. There are other options where individuals may also join Linux training classes.

My tips for the Red Hat RHCE exam

Last week I attended the Red Hat RH300 course (fast track) in Amsterdam and did the RHCSA and RHCE exams on the final day. I passed both RHCSA (283/300 points) and RHCE (300/300 points). I had a great teacher because, apart from technical stuff, I also learned how to approach the exams.

The objectives for both RHCSA and RHCE are well documented on Red Hat’s site. You should start to make sure you know everything inside out. Practise, practise, practise. Learn to use the documentation that ships with RHEL, as this is the only help available: no internet access is provided during the exam. There are several books available that help prepare and Red Hat has very good courses as well, that I really recommend. I assume you should be able to study this all one way or the other.

One advise on this though: don’t try to remember everything but remember the references instead. If you know a man page has examples you can use, just remember the man page. If you know documentation is in a separate package, remember the package name. A references takes less ‘memory’ in your head, so you can remember more. This will speed up your work significantly.

But wait, technical knowledge is just one challenge. Watch out for the pitfalls:
Pitfall #1: Time
Most experienced Linux sysadmins will probably be able to pass the exam if there was no restriction on time. You could test, trial-and-error and read man pages all day long. Even start from scratch when you seriously broke something. Well, it’s time to wake up: in reality time on the exam is (very) limited. And yet many candidates do not manage their limited exam time.

A classic example: spending too much time on something that does not work right away. Instead, accept the fact it doesn’t work now and continue with other tasks or else time will run out. When you have given everything a first attempt, you can always return to a task that you skipped before.

Not only should you know immediately what to do when you read the tasks, you need to know the fastest way to configure something. Yes, the fastest way. Not the way you prefer to do it, or have been doing it until now. I’ve heard people complaining about the GUI/TUI tools. And I agree a GUI is not something you want on a server. But hey, if ‘system-config-authentication‘ has a ready to fill-in form and makes you configure LDAP with TLS and Kerberos in 60 seconds. Why would you want to go for the manual way on the exam? Yet, some feel they are better off configuring this on the command line. There’s simply no time for that approach, nor will it bring in more points. Be smart, take the fast track.

Pitfall #2: Your assumptions
Reading is a big problem because candidates tend not do read very well on the exam. Especially when aware of Pitfall #1, they will not spend the first few minutes reading instructions. A waste of time, right? But in reality this will cost precious time later on because assumptions are made, but never checked. Is it a good idea to start working on something, without seeing the bigger picture?

I don’t think so. Sometimes, tasks are related but not grouped together. When you read everything first, you might find that doing two tasks together is easier. Or you might choose a different approach based on all information, instead on just a single task. Reading ahead helps you understand the bigger picture.

Imagine you are asked to configure, let’s say, NTP. Some assume they have to sync to a time source that is provided and then have to setup a NTP server and serve time to the local network. But isn’t is a waste of time to configure a NTP server, when all you have to do is setup a NTP client? This also occurs with tweaking configurations more than is being asked for. Keep it simple and do exactly what is asked for.

How I avoided the pitfalls
Value your own work through the eyes of a customer. Example: if a web server is perfectly configured but a firewall prevents access to it, then this does not work for a client. Website is down: zero value. Red Hat might also values your work on the exam like this. Keep that in mind.
Structure is another important thing to work on. This was my approach on the exam:
1. Imagine you are working for a client that has written down everything they want from you. Read it all and try to understand the bigger picture. Then reorganize it: group together what belongs to each other.
2. Install everything at once. After step 1 you should have identified all packages you need to install. Do it now. Then ‘chkconfig on‘ every service you will configure later. Why? Because it is easy and it prevents forgetting it later on. Remember: a perfectly configured service that does not start at boot brings in zero points.
3. Then setup the firewall for the services you identified at step 1 and installed at step 2. You probably need to tweak this as you go through the tasks, but just setup the basics now. This will make it easier later on.
On my exam the first 3 steps took less than 20 minutes and provided a solid base to build on.
4. Work through all tasks and remember: Be smart, take the fast track. Also, skip any task that you are stuck on for more than 10 minutes.
Reboot a few times and recheck everything you have finished so far. Your work is reviewed after a reboot anyway, so you should make sure your changes survive a reboot. The sooner you find a problem, the sooner you will be able to solve it.
5. When everything is done, carefully check the items a final time. Then you’re done. And, you probably have some time left!

RHCSA: A New Base Level Certification From Red Hat

The new version of Red Hat Enterprise Linux 7 is now released and with this new arrival, certifications under RHEL 6will no longer be current. Red Hat Certified Technician (RHCT) exam is no longer offered by Red Hat. RHCT exam is now replaced by RHCSA (Red Hat Certified System Administrator). This article attempts to provide a clear picture about new changes in RHCE certification.

RHCSA is the new addition to the performance based certifications, to strengthen IT professionals with superior training and performance based assessments in the IT industry. The certification title itself indicates more precise description of the duties held by people with this certification. More over RHCSA is built with thorough analysis of the knowledge and skills needed for modern system administrators. This is an outcome of technical survey, task analysis and feed backs from professionals world wide. In effect RHCSA is similar to RHCT except with some additions to include the result of feed backs from professionals.

RHCSA is the base system administration certification. Now onwards those wishing to earn RHCE on RHEL 7 must get RHCSA and write separate exam for RHCE. RHCE is now upgraded as a higher level system administration certification. A current RHCE will remain as prerequisite for advanced level certifications from Red Hat.

The main changes with RHCE exam on RHEL 7 is that previous RHCE Exam will be replaced by RHCSA Exam  and updated RHCE Exam . These two exams are now separate and RHCSA is not embedded with RHCE as RHCT was earlier. It is not necessary that one must get RHCSA first, before being eligible to write RHCE exam. If one passes RHCE exam first, then their record will be retained and when they passes RHCSA the earlier RHCE will be clubbed and person will be then RHCSA and RHCE. RHCSA exam is also performance based which evaluates skills through hands-on lab based system.

Certifications from Red Hat provide validation of a professional's technical expertise and knowledge. Nowadays enterprises looking for employees can give more preference to certifications as an input into hiring, promotions and other allowances, as these certifications are obtained from performance based exams.

RHCE Exam objectives — RHCE

This exam and the exam objectives provided here are based on the Red Hat Enterprise Linux 7 version of the exam. We are offering Red Hat Certified Engineer (RHCE) Exam (EX300) on Red Hat Enterprise Linux 6 via onsite and Individual Exam Sessions. View the Red Hat Enterprise Linux 6 exam objectives.
This guide provides information candidates may use in preparing to take the Red Hat® Certified Engineer (RHCE®) exam on Red Hat Enterprise Linux® 7. Red Hat is not responsible for the content or accuracy of other guides, books, online resources, or any other information provided by organizations or individuals other than Red Hat Training and Certification. Red Hat reserves the right to change this guide when appropriate. Candidates who have enrolled in forthcoming classes or exams are advised to check this guide periodically for changes.
Prospective employers should verify any and all claims by people claiming to hold this credential by requesting their certificate numbers and verifying it with the Red Hat certification verification tool online.
To earn the RHCE credential, one must also pass the Red Hat Certified System Administrator (RHCSA) exam. Someone can enroll in and take the RHCE exam without first having passed the RHCSA exam, but RHCE certification will not be issued until both credentials are earned by a candidate. In the event that a candidate has not yet earned RHCSA, Red Hat will retain the candidate's RHCE exam record and will attach that record to a candidates' RHCSA record once it is earned at a later date.

Performance-based exams

The RHCE exam is a performance-based evaluation of Red Hat Enterprise Linux system administration skills and knowledge. Candidates perform a number of routine system administration tasks and are evaluated on whether they have met specific objective criteria. Performance-based testing means that candidates must perform tasks similar to what they must perform on the job.

Authorized Training Partners

Only Red Hat and Red Hat Certified Training Partners administer the RHCE exam. Prospective candidates should exercise due diligence when purchasing a seat in an RHCE exam from a provider other than Red Hat itself. They should verify that the provider is, in fact, an authorized training partner or reseller in good standing. Please notify training@redhat.com about organizations that claim to offer the RHCE exam but are not Red Hat Certified Training Partners.

Scores and Reporting

Official scores for the RHCE Version 7 Training  exams come exclusively from Red Hat Certification Central. Red Hat does not authorize examiners, training partners, or other departments or individuals within Red Hat to report results to candidates. Scores on the exam are reported within 3 US business days.
Red Hat does not report performance on individual items, nor will it provide additional information upon request. This policy helps ensure impartiality and fairness for all candidates worldwide. Scores are used to establish whether certification should be issued and are reported for the benefit of candidates. Red Hat makes no representations regarding the use of scores for any other purpose, such as ranking or comparing candidates.

Format of the RHCE exam

The RHCE exam is a hands-on, practical exam that lasts 4 hours. Internet access is not provided during the exam. Outside materials are not permitted. Documentation that ships with Red Hat Enterprise Linux is available during the exam. Red Hat reserves the right to make changes to the format, including timing and the policies above. Such changes will be made public in advance through revisions to this document.

Preparation for the RHCE exam

Red Hat encourages all candidates for RHCE to consider taking one or more of its official training courses to help prepare. Attendance in these classes is not required, and one can choose to take just an exam. Many successful candidates who have come to class already possessing substantial skills and knowledge report that the class made a positive difference for them. To help you determine the best courses to take, Red Hat provides online skills assessment.
While attending Red Hat's classes can be an important part of one's preparation, attending class does not guarantee success on the exam. Previous experience, practice, and native aptitude are also important determinants of success.
Many books and other resources on system administration for Red Hat's products are available. Red Hat does not endorse any as preparation guides for any exams. Nevertheless, candidates may find additional reading deepens understanding and can prove helpful.

Exam objectives

RHCE exam candidates should consult the RHCSA exam objectives and be capable of RHCSA-level tasks, as some of these skills may be required in order to meet RHCE exam objectives. Red Hat reserves the right to add, modify, and remove objectives. Such changes will be made public in advance through revisions to this document.
