PAS-C01 Operations and Maintenance Practice Question
A company runs SAP on AWS and uses AWS Direct Connect for on-premises connectivity. The operations team notices that the SAP system is experiencing high latency when accessing an on-premises database. The network team confirms that the Direct Connect link is not saturated. What is the most likely cause of the high latency?

Correct answer & explanation
✓
The traffic is traversing a transit VPC with additional NAT instances
If the Direct Connect link is not saturated, the issue could be routing inefficiency. A transit VPC with EC2 instances acting as NAT or proxy can introduce additional hops and latency. VPN over Direct Connect is not relevant. MPLS is the underlying technology for Direct Connect. Increasing bandwidth does not reduce latency caused by routing.
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 traffic is traversing a transit VPC with additional NAT instances
Why this is correct
Additional hops in a transit VPC increase latency.
- ✗
The Direct Connect link is using a public VIF instead of a private VIF
Why it's wrong here
Public/private VIF affects reachability, not latency directly.
- ✗
The Direct Connect bandwidth is insufficient
Why it's wrong here
The team confirmed the link is not saturated.
- ✗
The on-premises network is using a VPN over the Direct Connect link
Why it's wrong here
VPN can add overhead but is not the most likely cause if latency is high but link not saturated.
