exam tips

good tips from Saurabh Gupta

components:

  • Compute (Nova)
  • Networking (Neutron)
  • Block storage (Cinder)
  • Identity (Keystone)
  • Image (Glance)
  • Object storage (Swift)
  • Dashboard (Horizon)
  • Orchestration (Heat)

In exam, you can do installation in two ways. Either you install each component manually or use packstack package/tool to do the installation.
For packstack installation you will generate a file and modify it as per the requirement mentioned in exam questions. Once the file is ready give it as input to packstack. Packstack will do all the installations for you.

Once the installation is done you can use CLI or GUI for doing further questions in exam. If you are new to Openstack, GUI is best option. It is good and gives you a graphical overview of what you are doing.

Some of the questions you can expect in exam post installation are:

  • Create Public and Private subnets
  • Create Users and Projects
  • Launch instance
  • Create Volumes
  • Attach volumes to instance.

Exam Overview

This exam is performance-based exam. Candidates need to perform tasks on a live system, rather than answering questions about how one might perform those tasks.

It tests your skills for:

  • Deploy and Configure a Red Hat OpenStack Platform Director
  • Manage Users, Projects, Flavors, Roles and Quotas
  • Configure and Manage Images
  • Configure and Manage Compute Nodes & Networking
  • Manage Cinder Storage
  • Use Heat Templates to Configure OpenStack Services and Resources

Exam Contents

The certification exam is very comprehensive. It ensures you have a complete hands-on understanding of OpenStack installation and basic operations. All the installation and configuration commands need to be memorized to start with the first task.

After installation is complete either Command Line Interface or Horizon Dashboard can be used to perform the following administrative tasks:

  • First task would be deploying and configuring Red Hat OpenStack Platform Director
  • Once the nodes are up and running, then administrative tasks like launching instances, addition / deletion / restriction of users with respect to specific projects and roles, needs to be performed
  • You would be asked to define public and private network on which, few instances must be launched using some specific image
  • Specified volume must be created and attached to the instance
  • Floating IP address needs to be assigned to the launched instance and specified behavior must be ensured by implementing a correct set of rules while creating the security group

Summary

Overall the exam is comprehensive and hands-on experience with OpenStack is a must.

Here are some additional tips that can help while planning for this exam:

  • Few of the tasks would be inter-related, so it’s always better to read the complete set of questions at the start of the test and define your own strategy to execute the tasks
  • Start with the deployment process as soon as test starts and then utilize the installation time to be primed with the answers
  • The hands-on nature of this exam makes real-world experiences a critical facet of preparation. Duration of this exam is 3 hours. Exam results are emailed within 3 US business days following the exam.
