ANS-C01 Network Management and Operations Practice Question
A company uses AWS Client VPN to provide remote access to its VPC. Users report slow connection speeds. The CloudWatch metrics show high packet loss on the VPN connections. What is the most likely cause?
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
✓
MTU mismatch between the client and the VPN endpoint.
An MTU mismatch between the client and VPN endpoint can cause fragmentation and packet loss, leading to slow speeds. Option A is incorrect because an expired certificate would cause authentication failure, not packet loss. Option B is incorrect because subnet size affects IP address availability, not packet loss. Option D is incorrect because route propagation affects reachability, not packet loss.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The client certificate has expired.
Why it's wrong here
Expired certificate would prevent connection, not cause packet loss.
- ✗
The Client VPN subnet is too small.
Why it's wrong here
Subnet size affects IP address availability, not packet loss.
- ✓
MTU mismatch between the client and the VPN endpoint.
Why this is correct
MTU mismatch leads to fragmentation and packet loss.
- ✗
Route propagation is not enabled in the VPC route table.
Why it's wrong here
Route propagation affects routing, not packet loss.
