CV0-004 Practice Question: A financial services company is migrating a…
A financial services company is migrating a critical application to a hybrid cloud environment. The application must maintain sub-millisecond latency between the front-end and back-end components. The on-premises data center is located in New York, and the cloud region chosen is AWS us-east-1. The network team has established a dedicated AWS Direct Connect connection. After deploying the application, latency tests show 2 ms on average, which is acceptable. However, during peak hours, latency spikes to 10 ms. The cloud administrator suspects that the spike is due to increased traffic going over the VPN backup link instead of Direct Connect. What should the administrator do to resolve the issue?
⚠ Common exam trap
Many candidates assume increasing bandwidth or traffic shaping will fix the latency issue, but the real problem is that traffic is incorrectly routed over the VPN backup link, not that the Direct Connect link is saturated.
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
✓
Configure the cloud resources to use only the Direct Connect connection and disable the VPN.
The latency spike during peak hours is caused by traffic failing over to the VPN backup link, which introduces higher latency and potential congestion. By configuring cloud resources to use only the Direct Connect connection and disabling the VPN, the administrator ensures all traffic stays on the low-latency, dedicated path. This eliminates the possibility of traffic being routed over the VPN, which is typically slower and less reliable than Direct Connect.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Move the application to a different AWS region closer to the on-premises data center.
Why it's wrong here
us-east-1 is already close to New York; the issue is routing, not region distance.
- ✓
Configure the cloud resources to use only the Direct Connect connection and disable the VPN.
Why this is correct
Ensures all traffic uses the low-latency Direct Connect.
- ✗
Increase the bandwidth of the VPN backup link.
Why it's wrong here
VPN inherently has higher latency due to encryption and internet routing.
- ✗
Implement traffic shaping to prioritize application traffic over the Direct Connect link.
Why it's wrong here
Traffic shaping does not reroute traffic if it's already going over VPN.
