Quick Answer
The answer is VPC Flow Logs. This AWS service captures packet-level information about IP traffic flowing to and from network interfaces in a VPC, including metadata such as source and destination IPs, ports, protocols, and packet counts, without requiring any changes to the underlying infrastructure. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your ability to distinguish between services that handle network traffic monitoring versus logging or auditing—a common trap is confusing VPC Flow Logs with CloudTrail, which records API calls, or CloudWatch Logs, which stores logs but does not capture IP traffic directly. Remember that VPC Flow Logs are about the flow of packets, not actions or configurations. A useful memory tip: think of “Flow” as “packet flow” and “Trail” as “API trail”—if you need to see who sent what over the wire, choose Flow Logs.
This SOA-C02 practice question tests your understanding of networking and content delivery. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 SysOps Administrator needs to monitor network traffic in a VPC. Which AWS service provides packet-level information about IP traffic?
Amazon CloudWatch Logs
Why wrong: Incorrect because CloudWatch Logs stores log data but does not capture VPC traffic.
AWS CloudTrail
Why wrong: Incorrect because CloudTrail records API activity.
AWS Config
Why wrong: Incorrect because Config monitors resource configurations.
VPC Flow Logs
Correct because Flow Logs capture IP traffic metadata.
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
Option C is correct because VPC Flow Logs capture IP traffic information for network interfaces. Option A is wrong because CloudWatch Logs can store logs but not capture IP traffic directly. Option B is wrong because AWS Config records resource configuration changes. Option D is wrong because CloudTrail records API calls.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

AWS CloudTrail
Why it's wrong here
Incorrect because CloudTrail records API activity.
AWS Config
Why it's wrong here

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.
