Quick Answer
The answer is VPC Flow Logs, as this is the AWS service designed to capture IP traffic information for network interfaces, including those involved in a VPC peering connection. By enabling VPC Flow Logs on the peering attachment, you gain detailed visibility into the metadata of all traffic flowing between the peered VPCs, such as source and destination IPs, ports, and protocols, without needing any additional agents or routing changes. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this question tests your understanding of how to operationalize network monitoring across VPC boundaries, often appearing as a straightforward scenario where you must distinguish between logging services. A common trap is confusing CloudTrail, which records API calls, or AWS Config, which tracks resource configuration changes, with actual network traffic logs. Remember the memory tip: Flow Logs follow the flow of packets, not the clicks of users.
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 wants to monitor network traffic between VPCs in the same AWS Region that are connected via VPC Peering. Which AWS service can provide visibility into the traffic?
VPC Flow Logs
Flow Logs on the peering connection capture traffic.
AWS Config
Why wrong: Config tracks configuration, not traffic.
AWS Direct Connect
Why wrong: Direct Connect is for on-premises connectivity.
AWS CloudTrail
Why wrong: CloudTrail logs API calls, not network traffic.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
VPC Flow Logs
The correct answer is A because VPC Flow Logs can be enabled on the peering connection to capture traffic. Option B is wrong because CloudTrail does not capture network traffic. Option C is wrong because AWS Config does not provide traffic logs. Option D is wrong because Direct Connect is for on-premises, not VPC Peering.
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.
