The correct answer is the result of the load balancer health check for each instance. This metric directly confirms whether each instance is reachable and responding to application traffic, which is the fundamental requirement for monitoring application availability via health checks. Unlike performance indicators such as CPU utilization or disk space, a health check result provides a binary pass-or-fail status that tells you if the application is actually serving users, making it the only metric that verifies uptime against a service level agreement. On the CompTIA Cloud+ CV0-004 exam, this question tests your understanding that high availability across multiple availability zones depends on detecting instance failure, not just resource strain. A common trap is confusing performance metrics with availability metrics—remember that a server can have low CPU usage but still be unresponsive to traffic. For the exam, keep this memory tip: health checks check health, not performance.
CV0-004 Operations and Support Practice Question
This CV0-004 practice question tests your understanding of operations and support. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 setting up monitoring for a web application. The application must be highly available across multiple availability zones. Which of the following metrics should be monitored to ensure that the application meets its service level agreement (SLA) for uptime?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The result of the load balancer health check for each instance.
The load balancer health check result directly indicates whether each instance is reachable and responding correctly to application traffic. Monitoring these results allows the administrator to detect instance failures and verify that the application remains available across multiple availability zones, which is the core requirement for meeting an uptime SLA. Other metrics like throughput, disk space, or CPU utilization are performance indicators but do not directly confirm application availability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Network throughput per minute.
Why it's wrong here
Throughput is not a measure of availability.
✓
The result of the load balancer health check for each instance.
Why this is correct
Health check status indicates whether the application is responding correctly.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse performance metrics (CPU, disk, throughput) with availability metrics, assuming that high resource usage or low throughput directly indicates an outage, when in fact only the load balancer health check result provides a definitive binary signal of instance availability for SLA compliance.
Detailed technical explanation
How to think about this question
Load balancer health checks typically use HTTP/HTTPS GET requests to a configured endpoint (e.g., /health) and expect a specific status code (e.g., 200 OK) within a timeout period (commonly 5 seconds). If an instance fails three consecutive health checks, the load balancer marks it as unhealthy and stops routing traffic to it, which directly impacts the application's ability to meet an uptime SLA. In a multi-AZ setup, monitoring health check results per AZ also helps detect zone-level failures that could cause a regional outage.

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.
