20+ practice questions focused on Operations and Support — 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 Operations and Support PracticeA cloud administrator notices that a virtual machine running a critical application is using 95% CPU consistently. The application is single-threaded and performance is degraded. Which action should the administrator take to resolve the issue?
Explanation: The application is single-threaded, meaning it can only utilize one CPU core at a time. Increasing the CPU clock speed directly improves the processing speed of that single thread, which resolves the performance degradation. Option C is correct because migrating to a host with a higher CPU clock speed provides a faster core for the single-threaded workload.
A cloud engineer needs to ensure that a web application can scale out automatically during traffic spikes. Which design best practice should be implemented?
Explanation: Option D is correct because an auto scaling group combined with a load balancer automatically adds or removes VM instances based on predefined metrics (e.g., CPU utilization, request count), ensuring the web application scales out horizontally during traffic spikes without manual intervention. This aligns with cloud elasticity best practices for handling variable workloads.
A company uses a hybrid cloud model with an on-premises data center and a public cloud. The network team reports that traffic between the cloud and on-premises is experiencing high latency and packet loss. The cloud administrator verifies that the VPN connection is up. What is the most likely cause?
Explanation: When a VPN tunnel is up but traffic experiences high latency and packet loss, a mismatched Maximum Transmission Unit (MTU) size is a common cause. This occurs because packets larger than the tunnel's MTU must be fragmented, and if fragmentation is not properly handled (e.g., due to the DF bit being set), packets are dropped, leading to retransmissions and increased latency. The symptoms align with MTU issues rather than simple connectivity or throttling problems.
Which TWO metrics should be monitored to determine if a cloud database is experiencing a memory bottleneck?
Explanation: Swap usage (B) is a direct indicator of memory pressure; when the operating system moves memory pages to disk, it signals that the database cannot fit its working set in RAM, causing severe performance degradation. Page faults per second (E) measures how often the database must retrieve memory pages from disk; a sustained high rate indicates the buffer pool is too small for the workload, confirming a memory bottleneck.
A cloud administrator is troubleshooting an application that fails to connect to a database. The application and database are in the same VPC. Which THREE steps should the administrator take to diagnose the issue?
Explanation: Option B is correct because telnet or netcat can test basic TCP connectivity to the database port, confirming whether the database is reachable from the application server at the network layer. This step isolates whether the issue is a network connectivity problem versus an authentication or configuration issue within the database itself.

Practice all Operations and Support questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Operations and Support. 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
Operations and Support 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. Operations and Support is tested as part of the CompTIA Cloud+ CV0-004 blueprint. Practicing with targeted Operations and Support questions ensures you can handle any format or difficulty that appears.
