ANS-C01 Network Management and Operations Practice Question
A network engineer is monitoring a hybrid network with a VPN connection to AWS. The engineer notices periodic packet loss and high latency during peak hours. The VPN tunnel uses static routing. The on-premises bandwidth is 100 Mbps, and the VPN connection is limited to 1.25 Gbps. 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
✓
The on-premises internet connection is saturated.
The VPN connection's bandwidth (1.25 Gbps) is sufficient, but if the on-premises link is only 100 Mbps, any traffic exceeding that will cause congestion and packet loss. The VPN tunnel itself is not the bottleneck.
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 VPC route table has a blackhole route for the on-premises CIDR.
Why it's wrong here
A blackhole route would cause complete loss, not periodic.
- ✓
The on-premises internet connection is saturated.
Why this is correct
The 100 Mbps link is likely overwhelmed during peak hours, causing packet loss and high latency.
- ✗
The VPN tunnel is using the incorrect encryption algorithm.
Why it's wrong here
Incorrect encryption would cause the tunnel to fail, not periodic packet loss.
- ✗
The VPN tunnel is exceeding its maximum bandwidth limit.
Why it's wrong here
The tunnel limit is 1.25 Gbps, far above the 100 Mbps link.
