What Is A EX210?

TL;DR
  • EX210 is Red Hat's Certified Specialist in Cloud Infrastructure exam, a hands-on test of Red Hat OpenStack Platform administration.
  • The exam is one four-hour section of performance tasks in a working OpenStack cloud, not multiple choice.
  • Current Red Hat guidance lists a USD 500 standard exam list price, with regional pricing possible.
  • Configurations must survive a reboot without intervention, so persistence is part of every task.

What the EX210 Actually Is

EX210 is the exam code for the Red Hat Certified Specialist in Cloud Infrastructure credential, issued by Red Hat, Inc. If you have landed here after searching "what is a EX210," the short answer is this: it is a practical, performance-based examination that proves you can administer a Red Hat OpenStack Platform cloud. You are not asked to recognise the correct answer from a list. You are placed in a working cloud environment and asked to make things happen.

Because the acronym "EX210" can be encountered in other contexts, it is worth being precise: everything on this page concerns the Red Hat exam and nothing else. For a quick orientation to related phrasing, see our companion pages on what EX210 is, what EX210 stands for, and the broader EX210 certification overview.

Red Hat positions this credential for cloud operators, the people responsible for day-to-day running of an OpenStack deployment: managing the control plane, securing it, handling users and projects, provisioning storage and networks, operating compute nodes, monitoring, automating deployments, and troubleshooting when something breaks.

Why You See Two Names for One Exam

Red Hat's current exam and credential pages use the name Red Hat Certified Specialist in Cloud Infrastructure. However, some legacy URLs and older text still refer to the same credential as Red Hat Certified System Administrator in Red Hat OpenStack. The legacy address for the credential page even carries "rhcsa-rhos" in its path.

If you see both names while researching, you are almost certainly looking at the same exam under its older and newer branding. Employers and job postings may use either, so it helps to recognise both when scanning requirements. Our pages on what EX210 means and EX210 meaning cover the naming question in a bit more depth.

Naming caution: Do not confuse EX210 with other Red Hat exams such as EX200 or EX310, or with OpenShift certifications. EX210 is specifically about operating Red Hat OpenStack Platform infrastructure.

How the Exam Works: Four Hours, Hands-On, Live Cloud

The format is what separates EX210 from most IT certifications. According to Red Hat, the exam consists of hands-on systems-administration tasks carried out in a working Red Hat OpenStack Platform cloud, and results are evaluated against objective outcomes. The exam is a single section lasting four hours.

What that means in practice

  • Performance tasks, not questions. Red Hat does not publicly specify the exact number of tasks or the split between scored and unscored items. Treat any claim of a fixed question count with suspicion.
  • Outcome-based grading. The environment is checked for the result you were asked to produce, not for the particular commands you typed.
  • Persistence matters. Configurations must survive a reboot without intervention. A change that works until the next restart will not earn credit.
  • No outside help. Outside assistance is prohibited under the general certification handbook. The exact inventory of product documentation available during the exam is not spelled out on the exam page, so confirm the current rules before you sit.

Be wary of third-party descriptions that claim a multiple-choice format, around 60 questions, or a 90-minute limit. Those do not match Red Hat's published description of this exam. If you want a sense of how demanding the hands-on format feels, our guide on how hard the EX210 exam is walks through the difficulty factors.

The Ten Objective Areas You Are Tested On

Red Hat publishes ten top-level exam-objective headings. These are objective headings, not a course syllabus, and Red Hat does not publish percentage weights for them, so you cannot know which area carries the most marks. Prepare broadly. For a deeper breakdown of each area, read our complete guide to all 10 EX210 content areas.

Domain 1: Manage the Red Hat OpenStack Platform control plane

The control plane is the brain of the cloud. Expect to work with the services that make an OpenStack deployment function and to keep them healthy.

  • Understanding which services run where and how they depend on one another
  • Checking service status and restarting or adjusting services safely

Domain 2: Manage infrastructure security

Securing the cloud itself rather than just its users.

  • Protecting infrastructure-level components and communications
  • Applying security settings that persist across restarts

Domain 3: Manage user security

Identity and access for the people and projects that consume the cloud.

  • Creating and managing users, projects, and roles
  • Controlling what each identity is permitted to do

Domain 4: Manage application deployment resources

The building blocks tenants use to launch workloads.

  • Working with images, flavors, and related deployment resources
  • Preparing resources so instances can be launched correctly

Domain 5: Manage storage in Red Hat OpenStack Platform

Providing and managing persistent and ephemeral storage for instances.

  • Creating, attaching, and managing storage volumes
  • Understanding how storage backends integrate with the cloud

Domain 6: Manage networking

Connectivity is where many tasks quietly fail, so this area rewards careful practice.

  • Building tenant and external networks and the routing between them
  • Managing addressing, security rules, and instance connectivity

Domain 7: Manage compute node operations

The hypervisor hosts that actually run instances.

  • Operating and maintaining compute nodes
  • Managing where and how instances run

Domain 8: Monitor operations

Knowing what the cloud is doing before users tell you something is wrong.

  • Reading service state, logs, and resource usage
  • Using monitoring data to confirm health

Domain 9: Automate cloud application deployment

Moving from manual steps to repeatable deployments.

  • Using orchestration and templating to deploy application stacks
  • Writing definitions that produce consistent results

Domain 10: Troubleshoot operations

Diagnosing and fixing broken behaviour in a live cloud.

  • Isolating faults across compute, storage, and networking
  • Using logs and service status to find root causes

Key Takeaway

Troubleshooting is listed last, but in a live-cloud exam it behaves like a cross-cutting skill. Practice diagnosing failures in networking, storage, and compute rather than only building things correctly the first time.

Who Should Sit This Exam

EX210 suits system administrators and cloud operators who run, or aim to run, Red Hat OpenStack Platform environments. It fits engineers moving from Linux administration into private-cloud operations, and OpenStack operators who want a vendor-recognised, practical credential to document their skills.

Job titles that typically align with this skill set include cloud operator, cloud infrastructure engineer, and Linux/OpenStack administrator. Employers that run Red Hat OpenStack Platform, such as service providers, telecommunications organisations, and large enterprises with private clouds, are the natural audience. For more on the roles and the market, see EX210 jobs, the EX210 salary guide, and our ROI analysis of whether the certification is worth it. We deliberately avoid quoting salary figures here because Red Hat does not publish them and we will not invent any.

Prerequisites and Preparation Path

Red Hat does not set a mandatory degree, a fixed number of experience hours, or a required training-hour count. The exam page recommends the following background:

  • RHCSA or comparable work experience and skills in Red Hat Enterprise Linux administration.
  • CL110 and CL210, or comparable Red Hat OpenStack Platform experience.
  • A careful review of the published exam objectives.

Red Hat explicitly states that course attendance is not required. The courses are a recommended route, not a gate. For a fuller treatment, see EX210 requirements and our overview of EX210 training.

A note on versions

The current public EX210 page does not publish a numeric platform version or a blueprint revision year. It says the objectives reflect the most recent available product and points candidates to a version selector at purchase. Separately, Red Hat's CL211 course (OpenStack Administration II with exam) is built on RHOSP 16.1 and RHEL 8.2, but that is a training baseline and should not be read as proof of which version your exam will use. Confirm your version at checkout and practise on a matching environment.

Fees, Booking, Retakes and Results

Cost

Red Hat's standard certification-exam list price is USD 500. Regional pricing may differ, and the exact EX210 checkout amount in your region should be confirmed when you book. Red Hat publishes no member versus non-member price difference, and reseller discounts are not the issuer's fee. For the full picture, see EX210 certification cost.

Delivery

Red Hat delivers its own proctored exams in individual, remote, and classroom formats, subject to availability for EX210 specifically. This is Red Hat's own delivery, not a verified Pearson VUE or PSI appointment. Remote testing requires compatible equipment and live proctoring where booked. Scheduling details are covered in EX210 exam dates.

Retakes

Red Hat's program guide describes one free second attempt for an initially purchased paid exam, and the EX210 page also notes that a retake is available after an unsuccessful first attempt. Check the current terms at booking time.

Results and scoring

Red Hat's materials give slightly different timing: the EX210 page says results are usually available within three US business days and reported as total scores, while the general guide says within five business days with objective-area feedback. Plan for the longer window rather than counting on the shorter one. You will not receive feedback on individual exam items. A numeric pass mark was not verified in the current official exam page or program guide, so see our note on the EX210 passing score and the discussion of the EX210 pass rate, where we explain why no credible credential-wide figure exists.

Validity and Renewal

The credential is current for three years. Red Hat's May 2026 framework and FAQ describe several renewal routes: retaking the highest-level exam, adding a certification at the same level, or advancing to a higher level, with specialization and transcript rules still applying. The program guide also supports retaking the original exam to renew that credential.

Conflicting guidance: An older standalone Red Hat page says Specialists renew only by retaking their own exams and otherwise become non-current. The newer framework is broader. Where they differ, prefer the updated May 2026 framework, but note that retaking EX210 remains the most commonly verified route. No EX210-specific continuing-education quota exists, and RHCA continuing-education rules do not automatically apply.

Renew before your status lapses so you never have to explain a gap on your transcript.

Sequencing Your Preparation by Domain

Because the exam is a live-cloud practical, preparation should be lab-driven. Here is one way to order the domains, based on dependencies between them. For a fuller plan, see our EX210 study guide.

Week 1

Control plane and monitoring

  • Domain 1: learn where services live and how to check them
  • Domain 8: get comfortable reading logs and service status early, since you will rely on them everywhere
Week 2

Identity and security

  • Domain 3: users, projects, and roles
  • Domain 2: infrastructure security settings and their persistence
Week 3

Resources, storage and networking

  • Domain 4: images, flavors, deployment resources
  • Domain 5 and Domain 6: volumes, networks, routing, and connectivity
Week 4

Compute, automation and fault-finding

  • Domain 7: compute node operations
  • Domain 9: orchestration and repeatable deployments
  • Domain 10: deliberately break things and fix them

After each lab, reboot the relevant service or node and confirm your change survived. That single habit addresses one of the exam's explicit requirements. The one-page EX210 cheat sheet is useful for a final review once you have done the hands-on work, and you can pressure-test your knowledge with the practice questions on our main practice test site.
