Question 1,693 of 1,621
ANS-C01 Network Management and Operations Practice Question
A company is using AWS Transit Gateway to interconnect multiple VPCs and on-premises networks. The network team wants to log and monitor all traffic flows across the Transit Gateway for security analysis. Which TWO actions should the team take? (Choose TWO.)
⚠ Common exam trap
The trap here is that candidates mistakenly think VPC Flow Logs can be enabled directly on the Transit Gateway itself (Option D), but AWS only supports flow logs on Transit Gateway attachments, not the Transit Gateway as a resource.
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
✓
Send the flow logs to Amazon CloudWatch Logs for monitoring and alerting.
VPC Flow Logs can be published to Amazon CloudWatch Logs, enabling real-time monitoring, alerting, and integration with AWS Lambda or third-party tools for security analysis. This allows the network team to capture IP traffic information for all flows across Transit Gateway attachments when flow logs are enabled on those attachments. Option C is correct because VPC Flow Logs must be enabled at the Transit Gateway attachment level (not on the Transit Gateway itself) to capture traffic traversing the Transit Gateway, as the Transit Gateway is a network transit hub and does not generate its own flow logs.
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 AWS Config rules to evaluate the Transit Gateway route tables.
Why it's wrong here
AWS Config is for configuration compliance, not traffic monitoring.
- ✓
Send the flow logs to Amazon CloudWatch Logs for monitoring and alerting.
Why this is correct
CloudWatch Logs can aggregate and analyze flow logs for security monitoring.
- ✓
Enable VPC Flow Logs on each Transit Gateway attachment.
Why this is correct
Flow logs at the attachment level capture all traffic traversing that attachment.
- ✗
Enable VPC Flow Logs on the Transit Gateway itself.
Why it's wrong here
Transit Gateway does not support flow logs directly; they must be enabled on attachments.
- ✗
Configure VPC Traffic Mirroring on the Transit Gateway.
Why it's wrong here
Traffic Mirroring is not supported on Transit Gateway; it works on EC2 instances.
