20+ practice questions focused on Security — one of the most tested topics on the CompTIA Cloud+ CV0-004 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Security PracticeA cloud administrator is configuring encryption for data at rest in a cloud storage service. The administrator wants to use a key that is generated and managed by the cloud provider but stored in the customer's account. Which key management option is being described?
Explanation: Customer-managed keys (CMK) are generated by the cloud provider's key management service but stored and managed (via policies, rotation) within the customer's account. This gives the customer control over key usage and access, unlike cloud provider-managed keys (SSE-S3) which are fully managed by the provider.
A company is deploying a web application in a cloud environment and needs to protect against SQL injection and cross-site scripting (XSS) attacks. Additionally, the company wants to block traffic from specific geographic regions. Which TWO services should be used? (Select TWO.)
Explanation: A Web Application Firewall (WAF) can inspect HTTP/HTTPS traffic to block SQL injection and cross-site scripting (XSS) attacks. Many WAF implementations also include a geo-blocking feature that allows blocking traffic from specific geographic regions. Therefore, a single WAF service can satisfy all requirements. Geo-blocking is a feature of WAF, not a separate service, so option B is redundant. Network ACLs, DDoS protection, and Security Groups do not provide application-layer inspection or geo-blocking.
A cloud engineer is configuring a web application on AWS and needs to ensure that only HTTP and HTTPS traffic from the internet is allowed to reach the EC2 instances. Which AWS service should be used to control inbound traffic at the instance level?
Explanation: Security groups are stateful virtual firewalls that control inbound and outbound traffic at the instance level. Network ACLs operate at the subnet level and are stateless.
A company is migrating to a public cloud and wants to understand security responsibilities. According to the shared responsibility model, which of the following is the customer responsible for in an IaaS deployment?
Explanation: In IaaS, the customer is responsible for securing the operating system, applications, and data, including patching the guest OS.
A security administrator needs to enforce least privilege for a Kubernetes cluster in a cloud environment. Which approach should be used to restrict permissions for pods that need to access the cloud provider's API?
Explanation: Using a service account with a role that has minimal permissions and attaching it to the pod ensures least privilege for pod-to-cloud API access.

Practice all Security questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Security. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Security questions on the CV0-004 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Security is tested as part of the CompTIA Cloud+ CV0-004 blueprint. Practicing with targeted Security questions ensures you can handle any format or difficulty that appears.
Yes. Courseiva provides free CV0-004 practice questions across all exam topics and domains. The platform includes topic-based practice, mock exams, missed-question review, bookmarked questions, and readiness tracking — no account required.
Difficulty is subjective, but Security is a high-priority exam concept tested in multiple ways — direct recall, scenario analysis, and command-output interpretation. Consistent practice is the best way to build confidence.
