ANS-C01 Network Management and Operations Practice Question
A company has a Direct Connect connection with a private virtual interface to a VPC. The network team wants to monitor the bandwidth utilization of the Direct Connect connection. They have enabled VPC Flow Logs for the VPC, but the flow logs do not show traffic that traverses the Direct Connect. The team needs a solution to capture the bandwidth usage of the Direct Connect connection. Which solution should they implement?
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 CloudWatch metrics for the Direct Connect connection.
Direct Connect publishes metrics to CloudWatch, including bandwidth utilization, connection state, and BGP status. These metrics can be used to monitor the bandwidth usage of the Direct Connect connection. VPC Flow Logs capture IP traffic within the VPC, not traffic on the Direct Connect physical connection. Option B is wrong because CloudTrail logs API calls, not bandwidth metrics. Option C is wrong because flow logs cannot be enabled on a Direct Connect virtual interface; they only capture traffic on VPC network interfaces. Option D is wrong because AWS Config rules are used for compliance and configuration monitoring, not for bandwidth metrics.
