ANS-C01 Network Implementation Practice Question
An organization is designing a hybrid network using AWS Direct Connect with a private VIF. They want to ensure high availability and failover. Which THREE components should be part of the design?
⚠ Common exam trap
Test-takers frequently think a single Direct Connect connection with multiple VLANs provides redundancy, but VLANs only separate traffic logically and do not protect against physical link failure, so multiple physical connections are required for true high availability.
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
✓
Two separate Direct Connect connections from different providers or locations.
Using two separate Direct Connect connections from different providers or locations ensures physical diversity, eliminating single points of failure. This design meets the high availability requirement by providing redundant paths for traffic, even if one connection or provider experiences an outage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A NAT gateway in each Availability Zone.
Why it's wrong here
NAT gateways are for outbound internet, not Direct Connect.
- ✓
Two separate Direct Connect connections from different providers or locations.
Why this is correct
Redundant physical connections prevent a single point of failure.
- ✓
BGP with multiple sessions and AS-path prepending for route preference.
Why this is correct
BGP allows traffic to fail over and control routing preferences.
- ✓
A VPN connection as a backup to the Direct Connect.
Why this is correct
A VPN can serve as a failover path if Direct Connect goes down.
- ✗
A single Direct Connect connection with multiple VLANs.
Why it's wrong here
VLANs do not provide physical redundancy.
