CV0-004 Practice Question: A cloud administrator notices that a cloud-based…
A cloud administrator notices that a cloud-based web application is experiencing intermittent latency during peak hours. The application runs on an auto-scaling group of virtual machines behind a load balancer. Which of the following should the administrator investigate FIRST to resolve the issue?
⚠ Common exam trap
Many candidates confuse load balancer tuning (SSL offloading, health checks) with capacity issues, overlooking that auto-scaling policies directly control the number of instances available to handle peak load.
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 auto-scaling group's scaling policies and thresholds
The intermittent latency during peak hours is most likely caused by the auto-scaling group's scaling policies not reacting quickly enough or being set with thresholds that are too high, leading to insufficient capacity under load. Investigating the scaling policies and thresholds first directly addresses the root cause—whether the group is adding instances too slowly or at too high a utilization trigger—rather than symptoms like health checks or DNS. This aligns with the operational best practice of verifying capacity management before tuning network or load-balancer settings.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Review the auto-scaling group's scaling policies and thresholds
Why this is correct
Incorrect scaling policies can lead to insufficient capacity during peak times, causing latency.
- ✗
Enable SSL offloading on the load balancer
Why it's wrong here
SSL offloading reduces processing overhead, so it would not cause latency.
- ✗
Verify the load balancer's health check interval
Why it's wrong here
Health check intervals affect instance registration, not response latency.
- ✗
Check DNS resolution times for the application domain
Why it's wrong here
DNS resolution issues cause failures or long initial connections, not intermittent latency.
