ANS-C01 Network Design Practice Question
A company is designing a hybrid network architecture that connects an on-premises data center to AWS using AWS Direct Connect. The company wants to ensure high availability and avoid a single point of failure. The on-premises router connects to two separate AWS Direct Connect locations. Which configuration should be used to meet these requirements?
⚠ Common exam trap
AWS often tests the misconception that multiple VIFs on a single connection or a single VIF attached to a Direct Connect gateway provide high availability, but the trap is that the physical connection itself remains a single point of failure unless two separate Direct Connect connections are used.
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
✓
Create two Direct Connect connections, each with a private VIF, and connect them to a Direct Connect gateway that is associated with a Transit VPC.
It uses two separate Direct Connect connections, each with a private VIF, both attached to a Direct Connect gateway. This eliminates a single point of failure at the connection level and, when combined with a Transit VPC, provides redundant, highly available connectivity from the on-premises data center to multiple VPCs. The Direct Connect gateway aggregates the private VIFs and allows traffic to be forwarded to the Transit VPC, which then routes to the attached VPCs, ensuring no single component failure disrupts the hybrid network.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create two private VIFs on the same Direct Connect connection and connect each to a different VPC.
Why it's wrong here
Both VIFs share the same physical connection.
- ✗
Create a single private virtual interface (VIF) on one Direct Connect connection and connect it to a single VPC.
Why it's wrong here
Single point of failure.
- ✓
Create two Direct Connect connections, each with a private VIF, and connect them to a Direct Connect gateway that is associated with a Transit VPC.
Why this is correct
Provides redundancy with two separate connections and a Transit VPC.
- ✗
Create a Direct Connect gateway and attach a single private VIF from one connection.
Why it's wrong here
Single point of failure.
