Quick Answer
The answer is VPC Flow Logs, Amazon CloudWatch, and AWS Network Manager. This combination works because VPC Flow Logs capture detailed IP traffic data across your Transit Gateway attachments, CloudWatch aggregates those logs into metrics and alarms for anomaly detection, and Network Manager provides a centralized global view of Transit Gateway performance metrics and topology. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your ability to distinguish network monitoring tools from application-level or advisory services—a common trap is selecting AWS X-Ray, which is for tracing application requests, not network flows, or Trusted Advisor, which offers static best-practice checks rather than real-time monitoring. Remember the mnemonic “Logs, Watch, Map”: VPC Flow Logs for raw data, CloudWatch for analysis, and Network Manager for the big-picture map of your Transit Gateway network.
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 is using AWS Transit Gateway to connect multiple VPCs and Direct Connect. The network team wants to monitor network performance and detect anomalies. Which THREE AWS services should the team use together to achieve this goal? (Select THREE.)
Amazon CloudWatch
For log aggregation and metric analysis.
AWS Trusted Advisor
Why wrong: Provides best practice checks, not real-time monitoring.
AWS Network Manager
Provides network performance and topology views.
VPC Flow Logs
Captures network traffic data.
AWS X-Ray
Why wrong: For application tracing, not network monitoring.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon CloudWatch
Options A, C, and D are correct. A: VPC Flow Logs capture IP traffic information. C: Amazon CloudWatch can aggregate and analyze logs and metrics. D: AWS Network Manager provides a global view of Transit Gateway networks and performance metrics. Option B is wrong because AWS X-Ray is for application tracing, not network performance. Option E is wrong because AWS Trusted Advisor provides best practice checks, not real-time monitoring.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
