- Red Hat's current EX210 page and program guide do not publish a verified numeric passing score.
- EX210 is a 4-hour, hands-on exam in a working Red Hat OpenStack Platform cloud, not multiple choice.
- Configurations must survive reboot without intervention, so verify persistence on every task you complete.

What "Passing" Means on a Hands-On Exam
Searching for the EX210 passing score usually turns up a tidy number, like 70 percent or 700 out of 1000. For the Red Hat Certified Specialist in Cloud Infrastructure exam, that tidy number has not been verified in Red Hat's current official materials, and this article will not invent one. What we can do is explain what is known, what is not, and how to prepare so the missing number matters as little as possible.
EX210 is issued by Red Hat, Inc. and is a performance-based exam. You sit in front of a working Red Hat OpenStack Platform cloud for four hours and complete administration tasks. Those tasks are evaluated against objective results: either the resource exists and behaves as specified, or it does not. That is a very different animal from a multiple-choice test, and it changes how you should think about "passing."
If you are new to the credential itself, our explainers on what EX210 certification is and what EX210 stands for cover the naming. In short, current Red Hat pages use "Red Hat Certified Specialist in Cloud Infrastructure," while legacy URLs and some text still say "Red Hat Certified System Administrator in Red Hat OpenStack."
What Red Hat Has and Has Not Published
Here is a plain accounting of what the official sources support, so you can separate fact from folklore.
| Item | Status in Red Hat's current materials |
|---|---|
| Numeric passing score | Not verified on the exam page or program guide |
| Exam duration | 4 hours, one section |
| Question count | Not publicly specified; performance tasks |
| Scored vs. unscored split | Not publicly specified |
| Domain weightings | Not published; 10 objective headings only |
| Result reporting | Total score reported; objective-area feedback described in the program guide |
| Independent pass-rate dataset | None located |
The practical takeaway: you cannot reverse-engineer a safe margin from published weights or a published cutoff, because neither exists in the sources we verified. For a deeper look at what the data does and does not show about outcomes, see our EX210 pass rate analysis.
How Objective Grading Likely Shapes Your Result
Red Hat states that EX210 results are evaluated against objective results. Without inventing details about the grading engine, you can draw sound conclusions from that phrasing alone.
Outcomes beat effort
A half-finished network that almost routes traffic is not worth partial credit in your head, so do not count it as done. Whether a task earns credit depends on the end state of the cloud, not on how elegant your command history looks. Build the habit of confirming each deliverable from the outside: list the resource, show its attributes, and test the behavior the task describes.
No individual item feedback
Red Hat does not provide individual exam-item feedback. You will not receive a task-by-task postmortem, so the only reliable way to know you hit the mark is verifying during the exam. Treat your own verification pass as part of the work, not an optional extra.
Ten Domains, One Result: Where Points Come From
Red Hat lists ten top-level exam-objective headings. They are not published with percentage weights, and the list is not a course syllabus, so no domain can be called the "most valuable." Preparing for all ten is the safe reading. Our complete guide to all 10 EX210 content areas goes deeper on each; here is how to think about them through a scoring lens.
Domains 1 and 7: Control Plane and Compute Node Operations
These are the administrative backbone. Tasks here tend to touch services, nodes, and the way workloads land on hardware.
- Know how to inspect and manage OpenStack services on the control plane.
- Be comfortable with compute node lifecycle tasks and verifying node state afterward.
- Expect changes here to be tested for persistence after reboot.
Domains 2 and 3: Infrastructure Security and User Security
Security tasks reward precision. A misconfigured policy can look fine until someone tries to use it.
- Practice identity concepts: users, projects, roles, and what each can and cannot do.
- Verify access from the perspective of the affected user, not just as the administrator.
- Understand how infrastructure-level protections differ from tenant-level controls.
Domains 4 and 9: Application Deployment Resources and Cloud Application Automation
These domains cover the resources applications need and the automation that deploys them repeatably.
- Be fluent with images, flavors, and the resources instances depend on.
- Practice orchestration-style deployment so you can build a working stack from a template, not just from one-off commands.
- Confirm that automated deployments actually produce reachable, working workloads.
Domains 5 and 6: Storage and Networking
Storage and networking tasks are where small mistakes cascade into failures in other domains.
- Manage storage resources in Red Hat OpenStack Platform and attach, detach, and verify them.
- Build and troubleshoot tenant networking, including connectivity checks end to end.
- Remember that a volume or network that works until reboot is not a finished task.
Domains 8 and 10: Monitor Operations and Troubleshoot Operations
These are the diagnostic domains. They reward calm, systematic investigation.
- Know where to look for service state, logs, and resource health.
- Practice breaking something deliberately in a lab, then restoring it using only evidence from the system.
- Expect troubleshooting skill to help you across every other domain, since mistakes happen everywhere.
Format Facts That Affect Your Score
Several format details are stated by Red Hat and have direct scoring implications.
- One four-hour section. There is no break structure described, so pacing is entirely yours to manage.
- Performance tasks in a live cloud. You are administering a real RHOSP environment, which means your actions have real side effects on later tasks.
- Outside assistance prohibited. Under the general handbook, you cannot get help from others. The exact inventory of product documentation supplied on exam day is not published on the exam page, so do not plan around a specific reference being available.
- Remote or in-person delivery. Red Hat offers proctored individual, remote, and classroom delivery, subject to booking availability for EX210. Remote testing requires compatible equipment and live proctoring where booked.
Difficulty is a common worry given the open-ended format. We break down how demanding candidates find the exam, and why, in How Hard Is the EX210 Exam?
The Reboot Rule: Where Passing Attempts Quietly Fail
Red Hat's special conditions for EX210 state that configurations must survive reboot without intervention. This single rule is the most actionable fact for anyone worried about the passing score, because it describes a way to lose credit on work you believe is finished.
Key Takeaway
Make persistence part of your definition of "done." After completing a task that changes service or node configuration, ask whether it would still be in effect after a restart, and confirm it rather than assuming. Build this habit in your practice lab until it is automatic.
In practice, that means distinguishing between runtime changes and persistent configuration, and knowing which tool or file makes a change stick. A setting applied live but never written to configuration will pass your own quick test and fail the grader's reboot check. If you have time at the end of the exam, a deliberate review of the riskiest persistent changes is a better use of minutes than polishing something that already works.
Results Timing and Score Reporting
Red Hat's own pages are not perfectly consistent here, and it is better to say so than to promise a single turnaround.
- The EX210 exam page says results are usually available within 3 US business days and are reported as total scores.
- The general certification program guide says within 5 business days, with objective-area feedback.
- Neither source offers individual exam-item feedback.
Plan for the longer figure when you coordinate job applications or employer deadlines. If you do receive objective-area feedback, use it to focus a retake on the headings where you were weakest. Scheduling windows and deadlines are covered in EX210 exam dates and scheduling.
Retakes, Cost, and Renewal
Retake and fee mechanics
The standard Red Hat certification-exam list price is USD 500. Regional pricing and the exact EX210 checkout amount were not independently verified, so confirm the figure at booking. Red Hat publishes no member versus non-member differential, and reseller discounts are not the issuer's exam fee. The general program guide describes one free second attempt for an initially purchased paid exam, and the EX210 page states that a retake is available after an unsuccessful first attempt. Check the terms at purchase, since policies can change. For the full financial picture, see the EX210 certification cost breakdown.
Staying current
The credential is current for 3 years. The May 2026 framework and FAQ describe renewal by retaking the highest-level exam, adding a certification at the same level, or advancing to a higher level, with applicable specialization rules still mattering. Retaking EX210 is the commonly verified route. Note that Red Hat's legacy standalone pages describe a retake-only path and non-current status, so there is a documented wording conflict; prefer the updated May 2026 framework but verify against your own transcript. No EX210-specific continuing-education credit route is published. Whether the credential is worth the effort at all is explored in Is the EX210 Certification Worth It?
A Domain-Ordered Prep Plan
Because no weights are published, sequence your preparation by dependency rather than by supposed point value. Foundational control-plane and security work underpins everything else, and diagnostic skills should be sharpened last so they can draw on everything you have built. Our EX210 study guide expands on this; here is a compact version.
Foundations: Domains 1, 2, 3
- Control plane services, infrastructure security, and user and project management.
- Confirm your RHCSA-level Linux skills are solid, since Red Hat lists RHCSA or comparable experience as expected background.
Resources and Data Path: Domains 4, 5, 6
- Deployment resources, storage, and networking.
- Practice end-to-end builds, then test them after a reboot.
Operations and Automation: Domains 7, 8, 9
- Compute node operations, monitoring, and automated application deployment.
Troubleshoot and Rehearse: Domain 10 plus full runs
- Break and repair your lab, then run timed four-hour sessions.
- Use realistic drills from the EX210 practice test site to rehearse pacing and verification.
Red Hat's page says course attendance is not required, but it lists CL110 and CL210 or comparable Red Hat OpenStack Platform experience as the expected preparation, alongside RHCSA or comparable skills. Details are in our EX210 requirements guide and training overview. One version caution: Red Hat's CL211 course page uses RHOSP 16.1 and RHEL 8.2 as its training baseline, but that is a preparation baseline, not proof of the version your exam will use. The exam page directs candidates to a version selector, so confirm your version before you book.
When you are ready to test yourself under realistic conditions, the practice tests on the main site are built to help you find gaps before exam day. If you want a quick refresher on terms and facts, the EX210 cheat sheet condenses them onto one page.
Frequently Asked Questions
A numeric passing score was not verified in Red Hat's current EX210 exam page or program guide. Red Hat reports results as total scores, so prepare to complete and verify every task rather than aiming at an assumed percentage.
No. It is a single four-hour section of hands-on administration tasks in a working Red Hat OpenStack Platform cloud, evaluated against objective results. Claims of a 60-question or 90-minute format do not match Red Hat's description.
Red Hat's EX210 page says usually within 3 US business days, while the general program guide says within 5 business days. Plan for the longer window, and note that neither source provides individual exam-item feedback.
Red Hat states that a retake is available after an unsuccessful first attempt, and the program guide describes one free second attempt for an initially purchased paid exam. Confirm the current terms when you purchase, then use any objective-area feedback to target weak domains.
No. Red Hat says course attendance is not required, though it expects RHCSA or comparable skills and CL110 and CL210 or comparable Red Hat OpenStack Platform experience. No fixed experience hours are published.
It is current for 3 years. The May 2026 framework describes several renewal routes, and retaking EX210 is the commonly verified one. Older Red Hat pages describe retake-only renewal, so check your transcript and renew before the credential lapses.
