- Exam 402 is 70 multiple-choice questions in 105 minutes; 65 are scored and five are pilot items.
- You need a scaled score of 245 on a 100-350 range, which is not 70% correct.
- Eligibility is the first hurdle: valid F5-CA BIG-IP, F5-CTS BIG-IP LTM and F5-CTS BIG-IP DNS certifications.
- The five blueprint sections are unweighted, so give no domain a free pass.
The Difficulty Verdict: Where the Challenge Really Sits
The F5 Certified Solution Expert, Cloud credential (F5-CSE Cloud, awarded through Cloud Solutions exam 402) is hard, but not in the way most candidates expect. The questions themselves are multiple choice. The difficulty comes from three places: the prerequisite chain you must complete first, the breadth of an architecture-level blueprint, and scenario questions where several answers sound plausible and only one fits the stated constraints.
No official pass rate has been published for this exam, and any site quoting one, including the "99% pass rate" marketing seen on some third-party prep pages, offers no issuer evidence. For a deeper look at what is and is not known, see our breakdown of the F5-CSE Cloud pass rate. In place of a statistic, this guide gives you a structural view of where candidates struggle.
The Eligibility Wall Before You Can Even Book
For many candidates, the hardest part of F5-CSE Cloud is qualifying to sit it. The current 402 support page requires all three of the following to be valid at the same time:
- F5-CA BIG-IP (the administrator credential)
- F5-CTS BIG-IP LTM
- F5-CTS BIG-IP DNS
One technology-specialist credential alone is insufficient. According to F5's Cloud learning path, the route runs through the five F5CAB administrator exams (or an eligible legacy administrator route), then LTM exams 301a and 301b, then DNS exam 302, and finally Cloud Solutions 402. Be cautious with third-party pages claiming that any single CTS credential is enough; they conflict with F5's published requirement.
F5 does not publish a mandatory degree, a fixed number of experience years, or required training hours. The expected candidate has direct cloud-infrastructure experience plus architecture and integration competence, but that describes the target profile rather than a gate. Our F5-CSE Cloud requirements guide walks through the full checklist, and the certification cost breakdown covers what the prerequisite exams add to your total spend.
Exam Mechanics: 70 Questions, 105 Minutes, Scaled 245
The format details below come directly from page 4 of the current 402 blueprint (identifier 402.42019).
| Item | Published Detail |
|---|---|
| Question count | 70 multiple-choice questions |
| Scored vs unscored | 65 scored, 5 pilot/beta items (you cannot tell which) |
| Time | 105 minutes, excluding approved accommodations |
| Passing score | 245 on a 100-350 scaled range |
| Fee | US$180 per attempt, plus local taxes or fees where applicable |
| Delivery | Pearson VUE test centers, English |
| Question styles | Some questions use exhibits or scenarios |
Why the scaled score matters for difficulty
A score of 245 on a 100-350 scale is not 70% correct. Scaled scoring means you cannot translate your practice-test percentage directly into a pass or fail prediction, and F5 does not publish a raw cut score. Sites converting 245/350 to "about 70%" are guessing. The practical consequence: aim for consistent mastery across all five sections rather than targeting a magic percentage. Our passing score explainer covers this in more detail.
Timing is workable but not generous. At 70 questions in 105 minutes you have roughly a minute and a half per item, and scenario questions with exhibits will consume more than their share. Practicing with realistic scenario stems matters more than speed drills.
Logistics that trip people up
- Registration requires two signed IDs, one government-issued with a photograph, matching your candidate account.
- The exam is closed-book; books, notes and personal electronics are restricted under the F5 Certified Candidate Agreement. Calculator provision was not verified, so confirm with the testing center.
- 402 is listed under Pearson VUE, not Certiverse, so claims of remote Certiverse delivery on third-party sites do not match F5's current provider list.

Domain-by-Domain Difficulty
F5 publishes five examination sections for 402 but no percentage weights, and objective counts should not be converted into weights. Treat each section as potentially decisive. For a fuller walkthrough of each area, read the F5-CSE Cloud exam domains guide.
Domain 1: Foundational Cloud Concepts
The vocabulary and models layer. It looks easy but sets up every scenario that follows.
- Cloud service and deployment models, and how each shapes application delivery decisions
- Where candidates slip: treating concept questions as trivia when they are really framing devices for later design choices
- Difficulty: moderate, mostly for candidates with on-premises-only backgrounds
Domain 2: Cloud Infrastructure Design
Likely the most demanding section for people coming from pure BIG-IP administration.
- Instance sizing and placement, licensing and support considerations
- SDN constraints and integration with BIG-IP deployments
- Design trade-offs driven by business requirements, not just technical preference
- Difficulty: high, because answers hinge on matching constraints to design rather than recalling a feature
Domain 3: Cloud Migration
Sequencing and dependency reasoning.
- Migration dependencies, validation steps and risk ordering
- Cloud bursting as a pattern with its own prerequisites and failure modes
- Difficulty: moderate to high; distractors often propose steps in a plausible but wrong order
Domain 4: Cloud Deployment
Turning a design into a running, supportable environment.
- Deployment choices across cloud environments and the integration points they create
- Operational validation after deployment
- Difficulty: moderate if you have hands-on cloud deployment experience, high if you do not
Domain 5: Cloud Orchestration and Automation
The automation layer, where lab time pays off most.
- RESTful APIs and the N/E/S/W-bound API model
- Deployment templates and orchestration sequencing
- Difficulty: high for candidates who have only configured devices through the GUI
What Scenario Questions Look Like
The exam's hardest items present a business situation with competing constraints and ask for the best design or next step. Third-party question dumps often fail here; some public samples use obviously irrelevant distractors such as office furniture or weather, which teach you nothing about real answer discrimination. Realistic items have distractors that would each be correct under a different set of constraints.
An illustrative example
This is an original practice-style scenario, not an actual exam question.
An organization runs a stable application in its own data center and wants to absorb seasonal traffic spikes using a public cloud, without re-architecting the application. The application relies on session persistence, and the security team requires that configuration be validated before any production traffic is shifted. What is the most appropriate approach?
- Move the entire application to the cloud immediately and decommission the data center to simplify operations
- Implement a cloud-bursting design, replicate the required application delivery configuration to the cloud environment, and validate it before directing overflow traffic there
- Increase the data center instance count permanently to cover peak load
- Route all traffic to the cloud at peak times only, regardless of persistence requirements
Reasoning: Option 2 matches the stated constraints: bursting handles seasonal overflow, replicated configuration respects persistence, and validation satisfies the security requirement. Option 1 ignores "without re-architecting," option 3 ignores the elastic goal, and option 4 ignores persistence. Notice that none of the wrong answers is absurd; each fails on one stated constraint. That is the pattern to practice.
Key Takeaway
Before choosing an answer, list every constraint in the stem (budget, timeline, persistence, validation, licensing, support). Eliminate any option that violates even one. This is the single most transferable skill for 402.
A Domain-Sequenced Study Plan
The sequencing below follows dependency logic: concepts feed design, design feeds migration and deployment, and all of them feed automation. Adjust the pace to your experience; this is a template, not a prescription. The full method is in our F5-CSE Cloud study guide.
Foundational Cloud Concepts, then Infrastructure Design
- Map each blueprint objective to a one-line explanation in your own words
- Work through sizing, placement, licensing and SDN integration as constraint-matching exercises
Cloud Migration and Cloud Deployment
- Sketch migration sequences and identify dependencies at each step
- Practice cloud-bursting scenarios and the validation logic around them
Orchestration and Automation, then full review
- Get hands-on with REST calls and template-driven deployment, since this section punishes theory-only study
- Finish with timed scenario sets, then revisit your weakest domain
If you are short on time, a condensed reference like the F5-CSE Cloud cheat sheet helps with final review, though it cannot replace scenario practice.
Study Resources: What Exists and What Does Not
F5 states that it does not create or maintain official certification study guides. That single fact shapes how hard this exam feels, because there is no official end-to-end text to lean on. What you do have:
- The official 402 blueprint (five pages), the authoritative statement of exam scope and format
- F5 documentation and hands-on lab time for the technologies the objectives reference
- Community material, such as the F5-hosted community study page, which explicitly says its content is unofficial and not developed, and the DevCentral reading list, which disclaims official-guide status
- Third-party practice providers, which vary widely in quality and sometimes contradict F5's published facts on duration, passing score or eligibility
Retakes, Renewal and the Cost of Failing
Failing costs more than the US$180 fee; it also costs time. The 402 blueprint and current catalog specify waiting periods of 15, 30 and 45 days after the first three failures, 365 days after the fourth, and 90 days subsequently. However, the July 2025 candidate agreement words the fourth-failure rule differently (up to 90 days or a new exam version, whichever is shorter, with prerequisite exams to be retaken and passed). That conflict is unresolved, so confirm current policy with F5 before planning around a fourth attempt.
On renewal: the credential is valid for two years from the qualifying exam, and retaking and passing 402 renews it. No dedicated recertification exam or CEU route was verified. Achieving or renewing Cloud can also extend qualifying prerequisite credentials. Since the prerequisites must be valid when you sit the exam, keep an eye on their expiry dates as well.
Whether the effort pays off depends on your own situation. No credential-specific salary survey or verified salary premium exists for this certification, so evaluate it using job postings and your own costs; our ROI analysis, salary guide and jobs overview show how to do that without relying on invented figures.
Cloud vs Security: Which Track Is Harder?
Cloud Solutions 402 and Security Solutions 401 are separate expert-level exams on F5's current tracks, and neither substitutes for the other. Difficulty is subjective and depends on your background:
| Factor | Cloud Solutions 402 | Security Solutions 401 |
|---|---|---|
| Focus | Cloud design, migration, deployment, orchestration | Security-oriented solutions |
| Best fit | Cloud and infrastructure architects, integrators | Security architects and engineers |
| Hardest part for most | Constraint-based design and automation | Depends on your security depth |
| Substitutable? | No. Each is its own credential with its own exam. | |
Choose by role and interest, not by perceived ease. If your daily work involves cloud environments and automation, 402 will feel more natural; if it involves security policy and threat mitigation, the other track may.
Frequently Asked Questions
It is demanding mainly because of the required prerequisite certifications and the architecture-style scenario questions. The exam is 70 multiple-choice questions in 105 minutes, with a scaled passing score of 245 on a 100-350 range. No official pass rate is published.
