What Is A F5-CA?

What the F5-CA Actually Is

The F5-CA is the F5 Certified BIG-IP Administrator credential, issued by F5. F5's current naming style is "F5 Certified Administrator, BIG-IP," abbreviated F5-CA, BIG-IP. The acronym is shared with unrelated credentials from other organizations, so it helps to be precise: this credential validates that you can administer F5 BIG-IP application delivery systems, the load balancers and traffic managers that sit in front of applications in many enterprise networks.

If you are just meeting the term, you may also want our short explainers on what F5-CA stands for and the F5-CA meaning. This article goes further and describes how the credential is structured, what each exam covers, and what the process of earning it looks like in practice.

The production blueprint is identified as F5-CAB.0425. It is a seven-page document that lists objectives for each exam. F5 states that the examples in the blueprint are illustrative rather than exhaustive, and that the blueprint does not target version-specific BIG-IP features. In other words, you are expected to understand how BIG-IP works as a platform rather than memorize the quirks of a single release.

Five Exams, Not One: How the Credential Is Built

The single most important structural fact about the F5-CA is that there is no combined initial examination. The credential is earned by passing five separately assessed exams. All five must be passed, and they may be taken in any order. The five exam headings are official exam objectives rather than five percentage-weighted sections of one sitting, so there is no single sitting in which domains compete for question share.

Because F5 does not publish percentage weights, be skeptical of any site that tells you which area is "heaviest." Equal question counts and objective counts do not establish domain weights, and no official weighting exists to cite. Our complete guide to the five F5-CA content areas walks through each exam's scope in more detail.

What each exam is about

Question Style, Timing, and Scoring

Each current exam has 30 multiple-choice questions and a 30-minute time limit. That works out to roughly one minute per question, which rewards candidates who can recognize a concept quickly. F5 staff confirmed in the production launch announcement and an April 28, 2025 clarification that some questions require two choices, so you cannot assume every item has exactly one correct answer. Read the stem carefully for an instruction such as selecting two options.

A note on sources: the individual F5CAB1-F5CAB5 support pages (updated December 18, 2025) state 30 items each, while an older overview page still says 25-30. The newer, exam-specific figure of 30 is the one used here. F5 does not publish the split between scored and unscored items, and production partial-credit rules for two-answer questions were not verified, so treat both as unknown.

The 245 scaled score

The passing score is 245 on F5's 100-350 scaled-score range, applied to each exam. This is not a published "70% correct" requirement, and you should not convert it to a percentage in your head. Scaled scoring exists so that scores remain comparable across different versions of an exam, which means the number of raw correct answers needed can differ slightly between forms. For a deeper explanation, read our F5-CA passing score breakdown.

Registration, Fees, and Delivery Options

To begin, you register in F5's certification program and accept the candidate agreement. You then schedule each exam individually, choosing between two delivery channels:

These totals exclude retakes and preparation costs. F5 publishes no member versus nonmember price split. Because you pay per exam, you can spread the cost across weeks or months rather than committing the full amount at once, which is a real advantage of the five-exam design. Our F5-CA certification cost breakdown covers the budgeting side, and the exam dates and scheduling guide covers booking logistics.

Retakes

Retake rules deserve a cautious reading. Current catalog pages list waits of 15, 30, and 45 days after the first three failures. Beyond that point, F5's own documents disagree: the catalog describes a one-year wait after the fourth failure and 90 days after the fifth and later failures, while the July 2025 candidate agreement describes a shorter wait after the fourth failure and requires prerequisite exams to be retaken. Because this conflict is unresolved, confirm the current rule with F5 before you rely on any single version of the policy.

What You Must Be Able to Do on a BIG-IP

The F5-CA rewards people who have actually configured the platform. Candidates should be comfortable with the following working vocabulary and tasks, since these are the building blocks that recur across several of the five exams:

• Virtual servers, pools, nodes, and members: understanding how a client connection is matched to a virtual server and then handed to a pool member.
• Health monitoring: how monitors decide whether a pool member is available and what happens to traffic when one fails.
• Persistence: why and how repeat requests from a client may be directed to the same server, and what trade-offs that introduces.
• Profiles, including TLS-related profiles: how protocol and encryption behavior is attached to a virtual server.
• Statistics and traffic flow: reading what the system reports to understand where a connection went and why.
• Upgrades and configuration management: planning a software change and protecting your configuration before you make it.
• Troubleshooting method: narrowing a problem to the client side, the BIG-IP, or the server side.

The Old 101/201 Route and What Changed

Before the current model, F5's administrator path used exam 101 followed by exam 201. F5's April 16, 2025 notice set the formal route change for May 1, 2025, and exam 101 retired on April 30, 2025. Candidates who held a qualifying 101 pass keep their 24-month eligibility window to complete 201. That means 201 is not universally unavailable, but the 101/201 route is not a fresh route for new candidates.

This distinction matters when you shop for study materials. Some third-party resources still center on 101/201, advertise question counts and time limits from the old format, or describe the credential in ways that do not match the five-exam structure. Always check that a resource references F5CAB1 through F5CAB5 and the current 30-question, 30-minute format before trusting its description of the exam.

Validity and Renewal

The F5-CA is valid for two years from the final required passing exam that awards the credential. That anchor point is worth noting: your clock starts when you complete the fifth exam, not when you pass the first.

Under F5's August 26, 2026 renewal policy, you can renew through either of two routes: the F5CABR recertification exam, or achieving or renewing a higher F5 certification that lists F5-CA as a prerequisite. Passing an intermediate exam alone does not establish renewal.

No continuing-education credit route is published. The older transition page also mentioned renewing by retaking all five CAB exams, but the latest renewal page lists F5CABR and higher-credential routes, so follow the current page.

Who Needs It and Where It Fits

BIG-IP systems are common in organizations that run business-critical web applications, which means the F5-CA is relevant to roles such as network engineers, application delivery engineers, infrastructure and operations staff, and security-adjacent administrators who manage traffic in front of applications. Employers that run F5 infrastructure, managed service providers, and F5 partners and resellers are natural places where the credential signals practical familiarity with the platform. See our overview of F5-CA jobs for more on role types.

On earnings, be careful. No credential-specific salary survey was retrieved, and general networking pay estimates do not measure what is attributable to this certification. Rather than quote a premium, treat the credential as one input to a role that depends on experience, scope, and employer. Our salary guide and ROI analysis discuss how to weigh cost against career goals without relying on unsupported pay figures.

For comparison searches, such as how the F5-CA stacks up against a broad networking credential like CCNA, the two cover different ground. CCNA is general networking; the F5-CA is specific to administering BIG-IP. Which is more useful depends on whether your target roles involve F5 platforms.

A Sensible Study Order

F5 allows any exam order, but that is a permission, not a recommendation. Because F5 does not create or maintain official certification study guides, you will lean on the blueprint, F5's preparation resources, and hands-on time. One editorially suggested sequence follows the logic of the platform itself:

Pace it to your own experience, and confirm your readiness before paying for each sitting. Our F5-CA study guide expands on this approach, the cheat sheet is useful for last-minute review, and our difficulty guide helps you gauge how much preparation you need. When you are ready to test your recall under time pressure, try the F5-CA practice tests on the main site, which are useful for rehearsing the 30-minute pace and the two-answer question style.
