AWS Certified Advanced Networking – Specialty (ANS-C01)Network Management and OperationsEasy
A global e-commerce company uses AWS Direct Connect for its critical operations. They have multiple Direct Connect connections to different AWS regions. The network team needs to ensure consistent bandwidth availability and quickly identify any potential bottlenecks or saturation points across their Direct Connect links. Which AWS service and metric combination would provide the most effective real-time visibility into the aggregated bandwidth utilization of all Direct Connect connections?
- AAWS Cost Explorer with 'Direct Connect Data Transfer Out' metric.
- BAWS Trusted Advisor with 'Direct Connect Redundancy Check'.
- CAmazon CloudWatch with 'ConnectionBpsIngress' and 'ConnectionBpsEgress' metrics for each Direct Connect connection.
- DAWS Network Manager with 'Transit Gateway Connect Peer Throughput' metric.
Show answer & explanationAnswer & explanation
Correct answer: C. Amazon CloudWatch with 'ConnectionBpsIngress' and 'ConnectionBpsEgress' metrics for each Direct Connect connection.
Amazon CloudWatch provides detailed metrics for Direct Connect connections, including ingress and egress bandwidth. Monitoring these metrics across all connections allows for real-time visibility into aggregated bandwidth utilization and potential bottlenecks.
Why the other options are wrong
- A. AWS Cost Explorer focuses on financial costs, not real-time network performance metrics.
- B. Trusted Advisor provides recommendations for best practices and cost savings, not real-time bandwidth monitoring.
- D. Network Manager monitors Transit Gateway connections, not the Direct Connect links themselves.
Direct Connect Bandwidth Monitoring
Utilizing Amazon CloudWatch metrics to observe the real-time data transfer rates (ingress and egress) over AWS Direct Connect connections to ensure optimal performance and identify saturation.
- Uses CloudWatch metrics.
- Monitors 'ConnectionBpsIngress' and 'ConnectionBpsEgress'.
- Essential for performance tuning and bottleneck identification.
Memory trick: CloudWatch is the direct path to seeing your Direct Connect's flow.
