OpenStack Exam Preparation – Practical Administration and Troubleshooting Lab

Prepare specifically for the practical requirements of the Certified OpenStack Administrator (COA) exam. This compact, hands-on course is designed for administrators, IT engineers and cloud operators who want to turn their existing OpenStack knowledge into exam-ready practical skills. The course can be delivered as standalone training or combined with our OpenStack fundamentals, administration or advanced courses. The focus is on practical administration tasks using Horizon and the modern OpenStack CLI.

What will you learn?

Deepen your practical OpenStack administration skills through exam-oriented scenarios. This course provides:

• Targeted preparation for typical COA task scenarios.

• Practical exercises with Keystone, Glance, Nova, Neutron, Cinder, Swift, Horizon and the OpenStack CLI.

• Repeatable lab scenarios for confidently performing standard administrative tasks.

• Structured troubleshooting exercises for common errors in compute, networking, storage and identity scenarios.

• A timed mock lab to simulate a practical exam situation.

By the end of the course, participants will be able to:

• Work confidently with Horizon and the OpenStack CLI in an existing OpenStack environment.

• Correctly use RC files and project credentials.

• Manage projects, users, groups, roles and role assignments.

• Upload, manage and provide images for instances.

• Administer instances, flavours, key pairs, snapshots and compute quotas.

• Configure project networks, subnets, routers, security groups and floating IPs.

• Create, attach, format, mount and restore block storage volumes from snapshots.

• Manage Swift containers and objects using the CLI.

• Systematically analyse typical errors related to instance access, network connectivity, credentials, quotas and volumes.

• Complete integrated OpenStack administration scenarios under time constraints.

Requirements:

• Basic Linux administration skills.

• Basic knowledge of virtualisation and cloud computing.

• Basic experience with OpenStack or prior participation in an OpenStack fundamentals or administration course.

• Confidence using the command line is recommended.

• A prepared OpenStack training environment with Keystone, Glance, Nova, Neutron, Horizon, Cinder and Swift is provided for the practical exercises.
