20+ practice questions focused on Troubleshooting — 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 Troubleshooting PracticeRefer to the exhibit. An administrator runs the command shown and receives the output. The administrator wants to ensure the VM uses SSDs for the OS disk. Based on the output, what is the current storage type?
Explanation: The storage account type 'Premium_LRS' indicates Premium SSD. In Azure, the storage account type for managed disks determines the underlying hardware: 'Premium_LRS' maps to Premium SSD, 'StandardSSD_LRS' to Standard SSD, and 'Standard_LRS' to Standard HDD. The command output would show the OS disk's storage account type as 'Premium_LRS', confirming it uses SSDs with premium performance.
An organization is using a hybrid cloud model with an on-premises data center connected to a public cloud via a dedicated Direct Connect circuit. Users on the corporate network report that access to cloud resources is intermittently failing. The cloud administrator pings the cloud gateway and sees packet loss. The on-premises network team confirms no issues on their side. The administrator reviews the cloud provider's status page and finds no outages. What should the administrator do next?
Explanation: Intermittent packet loss and no provider outage suggest bandwidth saturation on the Direct Connect circuit. Option A is wrong because submitting a support ticket to the cloud provider is unlikely to help if the provider has no issues and the circuit is simply congested. Option B is wrong because rebooting the on-premises router is disruptive and doesn't troubleshoot bandwidth. Option D is wrong because failing over to a backup VPN may not address the root cause and could mask it.
A cloud administrator receives an alert that a virtual machine (VM) is unresponsive. The VM is hosted on a hypervisor that shows high CPU ready time. Which of the following is the most likely cause?
Explanation: High CPU ready time indicates that the VM is ready to execute instructions but is waiting for the hypervisor to schedule physical CPU time. This is a classic symptom of over-provisioning vCPUs, where the total number of vCPUs assigned to all VMs exceeds the available physical cores, causing contention at the hypervisor scheduler level.
A company is designing a multi-cloud disaster recovery solution. They need to ensure RPO of 15 minutes and RTO of 1 hour for critical workloads. Which of the following should be implemented?
Explanation: Synchronous replication ensures that data is written to both the primary and standby environments simultaneously, guaranteeing zero data loss and meeting the 15-minute RPO. With a pre-configured standby environment in another cloud provider, failover can occur within minutes, satisfying the 1-hour RTO. This approach provides the lowest possible RPO and RTO for critical workloads.
A cloud engineer notices that an application is running slower than expected. Monitoring shows that the CPU utilization is consistently below 30%, but memory usage is at 95%. Which of the following is the most likely cause of the performance issue?
Explanation: When memory usage is at 95% and CPU utilization is low, the system is likely thrashing—the operating system is forced to page memory to disk (swap) to free RAM. Disk I/O is orders of magnitude slower than RAM, so even with idle CPU, the application stalls waiting for swap operations. This explains the performance degradation despite low CPU load.

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