CV0-004 Practice Question: A cloud administrator is investigating a…
A cloud administrator is investigating a performance issue with a cloud-based application. The application's response time has increased significantly. Monitoring shows low CPU and memory, but high network latency. Which two actions should the administrator take? (Choose two.)
⚠ Common exam trap
Many candidates confuse high latency with connectivity failures and incorrectly choose security group or load balancer settings, when in fact the correct approach is to use network diagnostic tools (trace tool and flow logs) to isolate the source of the delay.
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
✓
Use a trace tool to identify network hops and bottlenecks.
Using a trace tool (such as traceroute or MTR) allows the administrator to identify each network hop between the application and its users, revealing where latency is introduced. This directly addresses the symptom of high network latency by pinpointing congested or failing routers, misconfigured firewalls, or suboptimal routing paths.
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 security group rules for any restrictive outbound rules.
Why it's wrong here
Restrictive outbound rules would cause timeouts, not latency.
- ✗
Check the load balancer's connection draining settings.
Why it's wrong here
Connection draining affects termination of connections, not latency.
- ✓
Use a trace tool to identify network hops and bottlenecks.
Why this is correct
Traceroute helps pinpoint where network delays occur.
- ✗
Verify that the instances are in the same placement group.
Why it's wrong here
Placement groups are for low latency, but the issue is a change in behavior, not a static design flaw.
- ✓
Check for packet drops in the VPC flow logs.
Why this is correct
Packet drops can cause retransmissions and increased latency.
