- A
Create a CloudWatch alarm on the Direct Connect latency metric to send notifications when latency exceeds the threshold.
CloudWatch alarms can be set on latency metrics to trigger notifications.
- B
Subscribe to AWS Health Dashboard events for Direct Connect.
Why wrong: AWS Health Dashboard provides alerts for service events, not performance metrics.
- C
Enable CloudWatch metrics on the Direct Connect virtual interface to monitor latency.
CloudWatch metrics for Direct Connect include latency, packet loss, and throughput.
- D
Enable VPC Flow Logs to capture traffic patterns and latency.
Why wrong: VPC Flow Logs capture IP traffic metadata but do not measure latency.
- E
Configure a VPN CloudWatch metric to monitor the Direct Connect connection.
Why wrong: VPN metrics are for VPN connections, not Direct Connect.
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 uses AWS Direct Connect to connect its on-premises data center to a VPC. The network team needs to monitor the Direct Connect connection for performance issues and receive alerts when latency exceeds a certain threshold. Which TWO actions should the team take to meet these requirements? (Choose TWO.)
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
Create a CloudWatch alarm on the Direct Connect latency metric to send notifications when latency exceeds the threshold.
Option A is correct because AWS Direct Connect provides a built-in 'Latency' metric in CloudWatch that measures the round-trip time between the Direct Connect location and the AWS region. By creating a CloudWatch alarm on this metric, the team can trigger an SNS notification when latency exceeds a defined threshold, enabling proactive monitoring of performance issues.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse VPC Flow Logs (which capture traffic metadata) with performance monitoring tools, or assume that AWS Health Dashboard provides real-time latency metrics, when in fact only the Direct Connect latency metric in CloudWatch directly measures and alerts on latency.
Detailed technical explanation
How to think about this question
The Direct Connect latency metric is measured from the AWS side using ICMP echo probes sent from the Direct Connect router to the customer router at the Direct Connect location, providing a round-trip time (RTT) in milliseconds. This metric is available only for dedicated connections (1 Gbps and 10 Gbps) and not for hosted virtual interfaces; it updates every 60 seconds and can be used with CloudWatch anomaly detection for dynamic thresholding. In a real-world scenario, a sudden latency spike could indicate a failing optical transceiver or a routing issue at the Direct Connect location, and the alarm can trigger automated failover to a backup connection.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
