Passed EX436 High Availability Clustering

After my classroom exam was cancelled, I decided to take an individual exam.

Red Hat Individual Exam Experience

This was the first time I took an individual exam, and to be honest, having read plethora of reviews online about people having all sorts of problems, I was, to say the least, a bit worried.

There are two places that offer individual Red Hat exams in the UK, one in London, and one in Manchester. Either way it’s a two-hour drive from where I live. Driving in London is a no no, so I booked the exam in Manchester. The place is at the UKFast Campus and it has free on-site parking, amazing.

I didn’t get the personal testing station (the one that they show in the individual exam sessions video), but was provided with a 17″ laptop instead. I was monitored remotely by a Red Hat test proctor.

The whole experience was very positive. I had no issues with the laptop, no networking or performance problems. I already started considering taking all of my RHCA exams there.

EX436 Exam Experience

I’ve passed the exam with the score of 300/300.

I finished all the tasks in under 90 minutes, and then spent some time testing everything making sure that there are no issues. I’d say that 3 hours is plenty of time even if you need to troubleshoot something (I did have to troubleshoot a few things).

What I liked about this exam the most was the implementation of a complete solution. You build from the ground up until you have a highly available system.

As with other Red Hat exams that I’ve taken, the key thing for me was to know where to find information on a RHEL system.

    Also I used your notes to study.

    Thanks

  2. Hi Guys,

    I am appearing in EX436 exam next week. I have experience with RHEL cluster administration and also completed the Red Hat recommended training. I am looking for some sample exam questions to have an idea.

    Anyone please help me.

    • There is a comprehensive review lab at the end of the RH436 training course if you have access to RHLS.

      Good luck with your exam!

  3. Hi,

    Thanks Tomas for your reply. I have access to online course and have practiced comprehensive labs. I have another question regarding SELINUX context. With RHEL 7.1, can I use the below command, if it is asked in exam to mount Apache Document Root with SELINUX context on GFS2.

    pcs resource create clusterfs Filesystem device=”/dev/clustervg/ clusterlv” directory=”/var/www/html” fstype=”gfs2″ options=”noatime,context=system_u:object_r:httpd_sys_content_t:s0″ op monitor interval=10s on-fail=fence clone interleave=true

    Or if you can suggest me any other way to achieve the same.

    Thanks !!!

    • Although I’ve not verified your syntax, that command looks OK. You will likely want to use nodiratime with GFS2 as well.

  4. Hi,

    Today I have successfully passed my EX436 High Availability Clustering Exam with 300/300 score.

    First step towards RHCA …..

    Thanks for support and guidance here …..

  5. Hi Tomas,
    Congrats on your results!
    I’m really worried only for the fencing mechanism.
    Can you hint me if the exam requirements lead you in a specific stonith agent or they gave the freedom to choose.

    Usually a cluster requires shared storage and this leads me either to sbd (a.k.a poison pill) as I got lots of experience with that or fence_scsi/fence_multipath – which I haven’t deployed in real clusters.
