CV0-004 Practice Question: A cloud administrator is setting up monitoring…
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?
⚠ Common exam trap
Candidates often 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.
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
✓
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.
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.
- ✗
Percentage of disk space used on each instance.
Why it's wrong here
Disk usage is not an SLA metric for uptime.
- ✗
Average CPU utilization across all instances.
Why it's wrong here
CPU utilization does not directly measure application availability.
