Tips to pass COA exam.

  • Try to attempt all the questions in exams this will increase your chances passing the exam.
  • Don’t try to type all project name, volume name, username asked in questions. instead use Ctrl+Insert to copy and Shift+Insert to paste in Microsoft Windows operating systems. This will save lots of time to attempt other Qs. Shortcuts Ctrl+C and Ctrl+V are not supported in the exam terminal currently.
  • Practice and solve most of the Qs from horizon as it will be fast and save time compared to solve through commandline.
  • Root privileges can be obtained by running ‘sudo -i’.
  • The resources from  docs.openstack.org  are allowed during the Exam.
  • If the OpenStack Server Terminal is experiencing latency issues you can refresh exam window that will help.
  • Create one file in /tmp folder and log all skipped Qs and come back later if more time left. This will help to quickly navigate to skipped Qs directly if you have time.
  • Installation of services and applications are already included in this exam so no need to install anything else, may require modification of system security policies to solve some problems.
  • There are couple of Qs which cannot be solved through dashboard so practice on commandline as well.
  • If you failed in first attempt prepare harder and retake the exam within a week as you got some experience about exam and know the type of Qs.
  • After successfully passed the COA exam wait for 2 days and verify the certification details from link https://www.openstack.org/coa/coa-verify/

I can not disclose more information as I am under NDA after taking this exam.

  1. Hi Vishwanath,

    first of all, congratulations for getting such valuable Certification and thank you for sharing the tips needed during the exam,

    I am wondering if the first attempt is enough to pass successfully the exam, I mean, is the exam environment (VMs, question tabs,…) is clear enough to go forward to answers or you have to waste some time to be familiar with it? I faced such situations in CCIE & RHEL exams,

    if that will not break the NDA, the exam is based on which linux disto?

    Thanks in advance,

    1. Thanks for feedback.

      Yes. In first attempt you will get overall idea about exam environment, how to use exam terminals, even copy, paste is little tricky. After first attempt if you fail you will be very much confident to pass in second attempt.

      COA exam used Ansible to install OpenStack on Ubuntu but it is nothing to do with exam questions as most of the tasks are deal with day to day activities on OpenStack using commandline or dashboard.

      Only one suggestion try to complete all Q’s as simple ones will come later.

      Best of Luck for your exam.

  2. Hello Vishwanath,

    Thanks for sharing your experience and congratulations
    I’m wondering, how the openstack services were installed, were they installed on just one VM or deployed on multi nodes.

    Thanks

  3. Hi Vishwanath,

    Which openstack release is used for this exam?
    And if keystone commands would work or need to use openstack identity service commands

    For e.g.,

    1. keystone user-create –name swift –pass swift-secret
    2. openstack user create –domain default –project services –password swift-secret –enable –or-show swift

    1. Hi Madhu,

      COA exam is based on Liberty release.

      Openstack client is used in Liberty so you can use openstack commandline for all the tasks.
      In exam I will recommend use dashboard for most of the tasks and only use commandline for swift related tasks where you cannot use dashboard. It will save more time to cover multiple questions.

      Regards,

  5. I’m planning to study/appear for openstack exam (COA). But looks like many vendors have rebranded openstack like
    1. redhat
    2. mairantis
    3. oracle
    4. Suse

    I’m a bit confused which should I use, from production point of view the one by mirantis looks great from dashboard perspective. Actually I’m aware that the base concepts are same but openstack dashboard for each vendor is a bit different (and most of questions of COA can be done using GUI), even some of the vendors have changed the openstack commands a bit (CLI) which confused me a lot. Like if I go with vendor “A”, and dashboard/cli in exam is a bit different than that might create a bit of problem.

    Can you champs advise, how can I proceed with this case.
