CV0-004 Practice Question: A company has a hybrid cloud environment where…
A company has a hybrid cloud environment where on-premises servers communicate with cloud resources via a VPN connection. The network team notices intermittent connectivity issues and packet loss. The VPN tunnel is established, but performance is degraded. Which step should the team take first to diagnose the issue?
⚠ Common exam trap
Test-takers frequently assume the VPN tunnel is fully healthy because it is established, and they jump to restarting the tunnel or tweaking MTU without first using basic network diagnostics to isolate the performance issue.
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 traceroute and ping to measure latency and packet loss
B is correct because traceroute and ping are the foundational diagnostic tools to measure latency and packet loss across a VPN tunnel. Intermittent connectivity and packet loss often stem from path issues, MTU mismatches, or routing problems that these tools can isolate. Since the tunnel is established, the first step is to quantify the performance degradation before making configuration changes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Restart the VPN tunnel and monitor logs
Why it's wrong here
Not diagnostic first step.
- ✓
Use traceroute and ping to measure latency and packet loss
Why this is correct
Identifies network path issues.
- ✗
Increase the MTU size on the VPN tunnel
Why it's wrong here
May exacerbate issues.
- ✗
Check the CPU utilization of the on-premises VPN appliance
Why it's wrong here
Not the first step.
