- A
Adjust the autoscaling policy to add more instances immediately.
Why wrong: This is a reactive resolution, not a diagnostic step. Scaling should be based on analysis, not as a first step.
- B
Check for memory leaks in the application that could indirectly affect CPU.
Why wrong: Memory leaks do not directly cause high CPU utilization; they lead to high memory usage and potential swapping, but CPU diagnosis should focus on processes.
- C
Review the load balancer health check and traffic distribution settings for the backend pool.
Improper load balancer configuration can direct excessive traffic to this VM, causing high CPU.
- D
Identify the process consuming the most CPU using the OS performance monitoring tools.
This helps pinpoint the source of high CPU usage, whether an application process, database, or other service.
- E
Immediately increase the number of vCPUs assigned to the VM.
Why wrong: This is a resolution step, not diagnostic. It may temporarily alleviate symptoms but does not identify the root cause.
Quick Answer
The answer is to identify the process consuming the most CPU using the OS performance monitoring tools and to review the load balancer health check and traffic distribution settings. These two steps are correct because high CPU on a cloud web server often stems from either a runaway application process inside the VM or an external load-balancing misconfiguration that funnels excessive traffic to a single instance. By first checking the OS-level tools like top or Task Manager, you isolate whether the issue is process-specific, while simultaneously reviewing the load balancer rules rules out uneven traffic distribution or failed health checks that could overwhelm the VM. On the CompTIA Cloud+ CV0-004 exam, this tests your ability to prioritize layered diagnostics—starting with the VM’s internal state and the cloud platform’s traffic management—before diving into deeper troubleshooting. A common trap is jumping straight to scaling the VM without verifying whether a single process or a sticky-session imbalance is the root cause. Memory tip: “Process first, then proxy”—always check the OS process list before blaming the load balancer.
CV0-004 Troubleshooting Practice Question
This CV0-004 practice question tests your understanding of troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A cloud administrator is troubleshooting a virtual machine that is experiencing high CPU utilization during peak hours. The VM runs a web application and is hosted on a public cloud platform. Which TWO steps should the administrator take first to diagnose the issue?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Review the load balancer health check and traffic distribution settings for the backend pool.
Option C is correct because reviewing the load balancer health check and traffic distribution settings helps determine if the high CPU utilization is caused by uneven traffic distribution or unhealthy backend instances. If the load balancer is sending excessive traffic to a single VM due to misconfigured health checks or sticky sessions, the VM's CPU will spike. This is a first-step diagnostic action to rule out load balancing issues before investigating the VM itself.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often jump to scaling actions (like adding vCPUs or instances) as a first step, but the exam emphasizes systematic troubleshooting—starting with load balancer and OS-level diagnostics before making changes.
Detailed technical explanation
How to think about this question
Under the hood, load balancers use health checks (e.g., HTTP GET requests to a specified endpoint) to determine backend pool member status; if health checks fail or are misconfigured, the load balancer may route traffic to unhealthy VMs, causing CPU spikes. Additionally, traffic distribution algorithms like round-robin or least connections can become imbalanced if session persistence (sticky sessions) is enabled without proper cookie or source IP affinity configuration. In a real-world scenario, a misconfigured health check path (e.g., returning a 200 OK for a static page while the application is unresponsive) can lead to all traffic being sent to a single VM, overwhelming its CPU.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
