ANS-C01 Network Management and Operations Practice Question
A company is designing a highly available Direct Connect connection. Which THREE components should be deployed to meet this requirement? (Select THREE.)
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 Direct Connect connections to two different AWS Direct Connect locations.
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.
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 single BGP session over one of the virtual interfaces.
Why it's wrong here
Single BGP session does not provide high availability.
- ✓
Two Direct Connect connections to two different AWS Direct Connect locations.
Why this is correct
Provides physical diversity.
- ✗
A VPN connection as a backup to Direct Connect.
Why it's wrong here
While a VPN can be a backup, the question asks for components to deploy for HA Direct Connect, not a backup solution.
- ✓
Two customer routers (or one router with two physical interfaces) connecting to the two Direct Connect connections.
Why this is correct
Redundancy on the customer side.
- ✓
Two virtual interfaces (VIFs) configured on the Direct Connect connections.
Why this is correct
Logical redundancy for traffic.
