ANS-C01 Network Management and Operations Practice Question
Which THREE are best practices for designing a highly available AWS Direct Connect connection? (Choose 3.)
⚠ Common exam trap
AWS often tests the misconception that redundant virtual interfaces on a single physical connection provide high availability, but the physical link itself remains a single point of failure.
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 multiple Direct Connect connections to different AWS Direct Connect locations
Using multiple Direct Connect connections to different AWS Direct Connect locations provides geographic redundancy. If one location experiences an outage, traffic can fail over to the other location, ensuring high availability. This aligns with AWS best practices for resilient hybrid networking.
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 Direct Connect connection with redundant virtual interfaces
Why it's wrong here
Single connection is a single point of failure.
- ✓
Use multiple Direct Connect connections to different AWS Direct Connect locations
Why this is correct
Diverse locations provide geographical redundancy.
- ✓
Configure BGP with graceful restart and fast failover timers
Why this is correct
Speeds up convergence.
- ✓
Connect to multiple AWS Direct Connect routers in the same location
Why this is correct
Device-level redundancy.
- ✗
Use a single large Direct Connect connection instead of multiple smaller ones
Why it's wrong here
Lack of diversity.

Same concept, more angles
1 more way this is tested on ANS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is designing a highly available Direct Connect connection. Which THREE components should be deployed to meet this requirement? (Select THREE.)
medium- A.A single BGP session over one of the virtual interfaces.
- ✓ B.Two Direct Connect connections to two different AWS Direct Connect locations.
- C.A VPN connection as a backup to Direct Connect.
- ✓ D.Two customer routers (or one router with two physical interfaces) connecting to the two Direct Connect connections.
- ✓ E.Two virtual interfaces (VIFs) configured on the Direct Connect connections.
Why B: For high availability, you need at least two Direct Connect connections (preferably to different AWS locations), two customer routers (or one router with two interfaces), and two virtual interfaces (VIFs) to provide redundancy. Using BGP with multiple sessions ensures automatic failover.
