Question 1,412 of 1,621
ANS-C01 Network Implementation Practice Question
A network engineer is designing a hybrid network using AWS Direct Connect. The company requires high availability and wants to use a single AWS Direct Connect location with two connections from different customer routers. Which solution meets the high availability requirement?
⚠ Common exam trap
The ANS-C01 exam often tests the misconception that multiple VLANs or BGP sessions on a single physical connection provide high availability, but the trap here is that true redundancy requires separate physical paths and devices, not just logical separation or faster detection protocols like BFD.
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
✓
Use two AWS Direct Connect connections from the same location, each connected to a different customer router, and configure BGP sessions over both connections
It provides two physically separate AWS Direct Connect connections from the same location, each terminating on a different customer router. This architecture eliminates single points of failure at both the connection and router level. By configuring BGP sessions over both connections, the network can use BGP path selection and failover mechanisms (e.g., AS_PATH prepending or MED) to achieve high availability. This design meets the requirement for a single location while ensuring redundancy against a router or connection failure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a single AWS Direct Connect connection with multiple VLANs
Why it's wrong here
Multiple VLANs don't provide physical redundancy.
- ✗
Use a single AWS Direct Connect connection with two BGP sessions
Why it's wrong here
Single connection is a single point of failure.
- ✓
Use two AWS Direct Connect connections from the same location, each connected to a different customer router, and configure BGP sessions over both connections
Why this is correct
Two connections from different routers provide router-level redundancy.
- ✗
Use a single AWS Direct Connect connection with Bidirectional Forwarding Detection (BFD) enabled
Why it's wrong here
BFD provides fast failure detection but not physical redundancy.
