ANS-C01 Network Implementation Practice Question
Which THREE of the following are benefits of using AWS Transit Gateway over VPC peering for inter-VPC connectivity? (Choose three.)
⚠ Common exam trap
The ANS-C01 exam often tests the misconception that Transit Gateway always reduces latency compared to VPC peering, but in reality, VPC peering can have slightly lower latency because it creates a direct one-to-one connection without an intermediate routing hop.
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
✓
Transitive routing between all attached VPCs
AWS Transit Gateway enables transitive routing, meaning that traffic can flow between any attached VPCs without needing a full mesh of VPC peering connections. With VPC peering, each pair of VPCs requires a separate peering connection, and transitive routing is not supported — traffic cannot hop from one peered VPC to another. Transit Gateway acts as a hub-and-spoke router, simplifying connectivity and scaling to hundreds of VPCs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Transitive routing between all attached VPCs
Why this is correct
Transit Gateway supports transitive routing; VPC peering does not.
- ✗
Lower latency than VPC peering
Why it's wrong here
Latency is similar; no inherent advantage.
- ✓
Support for connecting to on-premises networks via Direct Connect and VPN
Why this is correct
Transit Gateway can connect to on-premises; VPC peering cannot.
- ✗
No additional cost compared to VPC peering
Why it's wrong here
Transit Gateway has per-attachment and data processing costs.
- ✓
Centralized management of network connections
Why this is correct
Transit Gateway provides a single point of management.
