The answer is to review the auto-scaling group's scaling policies and thresholds first. This is correct because intermittent latency during peak hours in an auto-scaled web application typically indicates that the scaling policies are not adding virtual machine instances quickly enough or are set with utilization thresholds that are too high, leaving the application under-provisioned during traffic spikes. On the CompTIA Cloud+ CV0-004 exam, this scenario tests your understanding of capacity management as a foundational troubleshooting step—before diving into load balancer settings or health checks, you must verify that the scaling logic itself is responsive. A common trap is to immediately suspect network or DNS issues, but the root cause is almost always a mismatch between scaling policy timing and demand. Memory tip: think "Policy before performance"—always check the scaling rules that control capacity before tuning anything else.
CV0-004 Operations and Support Practice Question
This CV0-004 practice question tests your understanding of operations and support. 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 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?

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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that 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.
Detailed technical explanation
How to think about this question
Auto-scaling groups use CloudWatch metrics (e.g., CPUUtilization, RequestCountPerTarget) to trigger scale-out actions, but cooldown periods and step scaling adjustments can introduce lag. Under the hood, if the scale-out threshold is set at 80% CPU and the application spikes to 90% in seconds, the group may take 2–5 minutes to launch new instances, during which latency increases. Real-world scenarios often involve 'thundering herd' traffic patterns where predictive scaling or scheduled scaling would be more appropriate than reactive policies.

→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.
