CV0-004 Practice Question: A company uses a hybrid cloud model and…
A company uses a hybrid cloud model and experiences intermittent connectivity issues between the on-premises network and the public cloud VPC. The administrator has verified that the VPN connection is established. Which of the following should the administrator check next?
⚠ Common exam trap
Many exam-takers assume an established VPN tunnel guarantees end-to-end connectivity, but CompTIA often tests that routing misconfigurations (e.g., missing static routes or incorrect VPC route propagation) are the most common cause of intermittent connectivity when the tunnel is up.
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
✓
Routing tables on both sides.
Since the VPN connection is established (tunnel is up), the issue is likely with traffic routing rather than basic connectivity. Routing tables on both the on-premises router and the cloud VPC must have correct routes pointing to the VPN gateway and the remote subnets; a missing or misconfigured route (e.g., a missing static route or incorrect VPC route table entry) will cause intermittent connectivity even when the VPN tunnel itself is active.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Firewall rules for outbound traffic.
Why it's wrong here
Outbound rules would affect all traffic, not just intermittent.
- ✗
Public IP address of the VPN gateway.
Why it's wrong here
The public IP is static and unlikely to change.
- ✓
Routing tables on both sides.
Why this is correct
Incorrect routes can lead to intermittent packet loss or misrouting.
- ✗
DNS resolution of cloud endpoints.
Why it's wrong here
DNS would cause consistent failure, not intermittent.
