AWS Certified Advanced Networking – Specialty (ANS-C01)Network Management and OperationsEasy
A global e-commerce company uses AWS Direct Connect to establish a dedicated network connection between its on-premises data centers and AWS VPCs in multiple regions. They are experiencing intermittent latency spikes and packet loss for traffic traversing the Direct Connect connection. The network team needs to quickly identify if the issue lies with the AWS network, the Direct Connect connection itself, or their on-premises network. Which AWS monitoring tool provides the most direct visibility into the health and performance of the Direct Connect connection?
- AAmazon CloudWatch Metrics for Direct Connect
- BAWS Transit Gateway Network Manager
- CVPC Flow Logs
- DAWS CloudTrail
Show answer & explanationAnswer & explanation
Correct answer: A. Amazon CloudWatch Metrics for Direct Connect
Amazon CloudWatch provides specific metrics for Direct Connect connections, including latency, packet loss, and data transfer rates. These metrics offer direct visibility into the health and performance of the Direct Connect connection itself, allowing the network team to quickly pinpoint issues related to the connection.
Why the other options are wrong
- B. AWS Transit Gateway Network Manager monitors global networks across AWS and on-premises, but CloudWatch provides more granular, direct metrics for the Direct Connect connection itself.
- C. VPC Flow Logs capture IP traffic information for VPCs but do not provide specific metrics about the Direct Connect connection's health or performance.
- D. AWS CloudTrail records API calls and events for governance, compliance, and operational auditing, not for real-time network performance monitoring.
Direct Connect Metrics
Amazon CloudWatch provides metrics specifically for AWS Direct Connect connections, offering insight into their health, performance, and usage.
- Monitors BGP status, connection state
- Tracks data transfer (in/out)
- Reports packet loss and latency
Memory trick: For specific AWS service health, CloudWatch metrics are your direct lens.
