CV0-004 Practice Question: Experiencing intermittent connectivity issues…
A company is experiencing intermittent connectivity issues between its on-premises data center and a public cloud environment over a VPN connection. Which TWO of the following should the administrator check to troubleshoot the problem?
⚠ Common exam trap
CompTIA often tests the misconception that intermittent VPN issues are always bandwidth-related, but the real culprit is usually routing misconfiguration or tunnel instability, which is why route validation and log/packet-loss analysis are the correct pair.
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
✓
Validate the route tables on both sides of the VPN.
Route tables control the path that traffic takes between networks. If the route tables on either the on-premises VPN device or the cloud virtual network gateway do not have the correct entries (e.g., missing routes for the remote subnet or incorrect next-hop IPs), traffic can be dropped or misdirected, causing intermittent connectivity. Validating these routes ensures that packets destined for the cloud or on-premises are properly forwarded over the VPN tunnel.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Verify that the internet bandwidth is sufficient.
Why it's wrong here
Bandwidth saturation might cause latency but not connectivity intermittent failures.
- ✓
Validate the route tables on both sides of the VPN.
Why this is correct
Incorrect routes can cause traffic to be dropped or misrouted.
- ✗
Ensure the cloud storage performance is adequate.
Why it's wrong here
Storage performance is unrelated to VPN connectivity.
- ✗
Check the DNS resolution of cloud endpoints.
Why it's wrong here
DNS is not used for VPN connectivity; VPN uses IP addresses.
- ✓
Review the VPN logs and monitor packet loss.
Why this is correct
Logs and packet loss metrics help identify connectivity issues.
