Study guide · Exam overview
The format, passing score, and six published domains of CompTIA Cloud+ CV0-004, plus what changed from the previous CV0-003 exam.
Exam version notice: This overview follows CompTIA Cloud+ exam objectives version 2.0 for CV0-004, reviewed in October 2026. CompTIA calls that version Cloud+ V4. It launched on September 24, 2024. The exam allows a maximum of 90 questions in 90 minutes, and CompTIA publishes a passing score of 750 on a scale of 100 to 900. CV0-003 is the previous series. Items tagged Extra are useful context the CV0-004 objective list does not name. Confirm the exam code, fee, and objectives with CompTIA before you register.
CompTIA Cloud+ is the vendor-neutral certification for people who design, deploy, operate, and troubleshoot cloud resources across more than one provider. CV0-004 checks whether you can pick a service model, place a workload for the right availability and cost, migrate it with a named strategy, secure identity and data, and explain a DevOps tool by the job it does. It is not an AWS, Azure, or Google Cloud architect exam, and it does not ask you to click through one vendor's console.
Figures below come from the CV0-004 objectives version 2.0 and CompTIA's Cloud+ pages reviewed in October 2026.
| Specification | CV0-004 (Cloud+ V4) |
|---|---|
| Level | Associate cloud operations. No prior certification is required. CompTIA recommends 2 to 3 years as a systems administrator or cloud engineer, plus Network+ and Server+ or equivalent knowledge. |
| Length of test | 90 minutes. |
| Question types | Multiple choice and performance-based questions. The stem says how many answers to choose. |
| Number of questions | Maximum of 90. |
| Passing score | 750 on a scale of 100 to 900. CompTIA does not publish the raw-score conversion. |
| Objectives | Version 2.0. Six domains. Example lists in the objectives are not exhaustive. |
| Languages | English and Japanese. Confirm availability with CompTIA. |
| Exam price | Confirm the current voucher price with CompTIA. Regional pricing changes. |
| Validity | Three years from the pass date. Confirm renewal options with CompTIA. |
| Later version | CompTIA usually retires an exam about three years after launch. The public page estimates 2027 for CV0-004. Confirm before you book. |
Book CV0-004. Use this table only to see what moved when the objectives were rewritten.
| CV0-004 domain | CV0-003 weight | CV0-004 weight |
|---|---|---|
| Cloud Architecture (was Cloud Architecture and Design) | 13% | 23% |
| Deployment | 23% | 19% |
| Operations (was Operations and Support) | 22% | 17% |
| Security | 20% | 19% |
| DevOps Fundamentals (new domain) | — | 10% |
| Troubleshooting | 22% | 12% |
Both exams used a maximum of 90 questions, 90 minutes, and a passing score of 750 on the 100 to 900 scale. The content shift is the reason to study the CV0-004 objectives rather than a CV0-003 book.
A certification earned on CV0-003 stays valid for three years from the pass date. It does not let you skip CV0-004 if you still need to sit the exam.
CompTIA publishes these CV0-004 weights. The 200 practice questions use the same share.
The largest domain. Models, availability, networks, storage, and cost.
How a workload gets into the cloud and stays defined as code.
How you watch, scale, back up, and retire resources.
Identity, compliance, controls, and the attacks a cloud operator is expected to name.
Source control, pipelines, integration styles, and the tools the objectives name.
Deployment, network, and security faults, including quotas and status codes.
Learn the unmarked rows first. The same map is in the core notes and flashcards.
| Pair | How to separate them |
|---|---|
| IaaS and PaaS | On IaaS you patch the guest operating system. On PaaS the provider patches the platform and you ship the application. |
| RTO and RPO | RTO is downtime. RPO is how much data you can lose. A hot site meets a short RTO. A cold site does not. |
| Block and object storage | Block storage is a disk with IOPS, attached to compute. Object storage is blobs over HTTP, usually with tiers. |
| Horizontal and vertical scale | Horizontal adds instances. Vertical makes one instance larger. Vertical hits a size ceiling and often needs a restart. |
| Rehost and refactor | Rehost moves the workload unchanged. Refactor changes the application so it can use cloud services. |
| Blue-green and canary | Blue-green switches all traffic between two full environments. A canary sends a small share first. |
| Incremental and differential | Incremental copies changes since the last backup of any type. Differential copies changes since the last full backup. |
| SAML and OAuth 2.0 | SAML federates sign-in. OAuth 2.0 delegates authorization. OpenID Connect adds sign-in on top of OAuth 2.0. |
| Terraform and Ansible | Terraform provisions infrastructure. Ansible configures what is already there. Drift is live state that no longer matches the code. |
| 401 and 403 | 401 means the caller is not authenticated. 403 means the caller is known and is not allowed. |
| Anti-affinity Extra | CV0-004 names host affinity, which pins a virtual machine to a host. Anti-affinity keeps copies apart. Learn affinity for this exam. |
Most items are multiple choice. Some ask you to choose two or three answers, and the stem says so. Performance-based items ask you to match a tool or storage type to a job, or to put a process such as vulnerability handling in order. Read FIRST, NEXT, and BEST as ordering words: the right control at the wrong step is still wrong.
CompTIA says the example lists in the objectives are not exhaustive. A question can use a technology that fits an objective even when the PDF did not print that product name. Do not expect a full vendor configuration lab.
A practical sequence if models, migrations, and identity still blur together.
Say who patches the operating system on IaaS, PaaS, SaaS, and FaaS. Then place public, private, hybrid, and community. The shared responsibility line moves with the model.
Region, zone, RTO, RPO, and hot, warm, and cold. Then hot, warm, cold, and archive storage, and reserved, spot, and pay-as-you-go. A cheaper tier that misses the RTO is the wrong answer.
Rehost, replatform, refactor, re-architect, retain, and retire. Then blue-green, canary, rolling, and in-place. Infrastructure as code should detect drift.
Horizontal versus vertical. Full, incremental, and differential. SAML versus OAuth 2.0, and 401 versus 403. Least privilege beats a broad role that "just works."
Git stores history. Terraform provisions. Ansible configures. Kubernetes orchestrates containers. Jenkins and GitHub Actions run pipelines. ELK holds logs. Grafana shows metrics.
Quotas, throttling, overlapping networks, missing routes, leaked credentials, and cryptojacking. Use the four flashcard decks until you answer before the card flips. Then take original questions and return to any domain under 75 percent. Use 90 minutes as the pace of the live exam. Treat the 100 to 900 estimate as a personal trend, not a prediction.
The overview, core notes, flashcards, and practice exams are all published.
Exam format, the 750 passing score, six domain weights, and the CV0-003 comparison.
Reference notes for models, migration, scaling, identity, DevOps tools, and troubleshooting.
40 recall cards in four decks, plus memory notes for models, backups, and the tool list.
200 original questions with custom exams, explanations, and an unofficial score on the 100-900 scale.
CompTIA allows a maximum of 90 questions and 90 minutes. Questions are multiple choice and performance-based. Confirm the current details with CompTIA before you book.
CompTIA publishes a passing score of 750 on a scale of 100 to 900 for CV0-004. This site converts a practice percentage linearly onto that scale and labels the result unofficial, because CompTIA does not publish the real conversion.
Study CV0-004. CompTIA launched it on September 24, 2024, and lists it as the current Cloud+ exam (V4). CV0-003 is the previous series. A voucher applies to the exam CompTIA is offering when you book, so confirm the code before you register.
Yes. CompTIA certifications are valid for three years from the date you pass. Renewal options change, so confirm the current policy with CompTIA.
No prior certification is required. CompTIA recommends 2 to 3 years as a systems administrator or cloud engineer, plus Network+ and Server+ or equivalent knowledge.
No. The practice questions on this site are original. They are not CompTIA exam items, and a practice score does not predict a result.
