The answer is AWS CloudWatch Events (EventBridge) with Direct Connect BGP metric alarms. This is correct because the `bgp_session_state` metric in the `AWS/DX` namespace reports the live status of a BGP session on a Direct Connect virtual interface; when the session drops to the `down` state, CloudWatch Events can trigger an automated action like a Lambda function or SNS notification, enabling you to automate BGP failure response on Direct Connect without manual intervention. On the ANS-C01 exam, this scenario tests your understanding of integrating monitoring with event-driven automation—a common trap is to assume AWS Config or Health checks handle BGP state, but only CloudWatch metrics capture the session’s binary up/down status. Remember the mnemonic: “BGP down? Bridge it with EventBridge.”
ANS-C01 Network Management and Operations Practice Question
This ANS-C01 practice question tests your understanding of network management and operations. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company has a hybrid network architecture with multiple VPCs connected via a transit gateway and on-premises via Direct Connect. The network team wants to automate the response to a BGP session failure on a Direct Connect virtual interface. Which AWS service can be used to monitor the BGP status and trigger an automated action?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS CloudWatch Events (EventBridge) with Direct Connect BGP metric alarms
Option C is correct because AWS CloudWatch Events (EventBridge) can monitor Direct Connect BGP session status via the `bgp_session_state` metric in the `AWS/DX` namespace. When the BGP session transitions to the `down` state, you can create an EventBridge rule that triggers an automated action, such as invoking a Lambda function or sending an SNS notification, enabling a rapid response to BGP failures without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
Systems Manager can automate actions but needs a trigger; BGP monitoring is better with CloudWatch.
✓
AWS CloudWatch Events (EventBridge) with Direct Connect BGP metric alarms
Why this is correct
EventBridge can trigger actions based on CloudWatch alarms for BGP status.

✗
AWS Config rules
Why it's wrong here
Config rules evaluate resource configurations, not real-time BGP status.
Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the misconception that VPC Flow Logs or AWS Config can monitor BGP status, but candidates must remember that BGP is a control-plane protocol and only Direct Connect metrics in CloudWatch provide the BGP session state for automation.
Detailed technical explanation
How to think about this question
The Direct Connect BGP session state metric (`bgp_session_state`) is published to CloudWatch every 5 minutes by default, with values of `0` (down) or `1` (up). EventBridge rules can match on state changes using event patterns or CloudWatch alarm state transitions, enabling near-real-time automation. In a hybrid network, a BGP session failure could cause traffic blackholing; automating the response (e.g., failing over to a backup Direct Connect or VPN) minimizes downtime.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
