Quick Answer
The answer is VPC Flow Logs, because they capture IP traffic metadata for all network interfaces in a VPC, enabling granular analysis of network traffic patterns and pinpointing latency sources in SAP HANA environments. By examining flow log records—such as source/destination IPs, ports, and packet counts—you can identify bottlenecks like excessive retransmissions or asymmetric routing during peak hours. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your ability to differentiate network-level diagnostics from other AWS services; a common trap is confusing VPC Flow Logs with AWS CloudTrail (which logs API calls) or AWS X-Ray (which traces application requests). Remember the memory tip: Flow Logs = network flow, CloudTrail = API trail, X-Ray = app ray.
This PAS-C01 practice question tests your understanding of technology. 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 runs an SAP HANA database on an AWS EC2 instance. The database experiences high latency during peak hours. The operations team suspects network bottlenecks. Which AWS service should be used to analyze network traffic patterns and identify the source of latency?
VPC Flow Logs
VPC Flow Logs capture IP traffic information for network interfaces, enabling analysis of traffic patterns and bottlenecks.
AWS X-Ray
Why wrong: AWS X-Ray traces application requests, not network-level traffic.
AWS Trusted Advisor
Why wrong: Trusted Advisor provides best-practice checks but not detailed network analysis.
AWS CloudTrail
Why wrong: CloudTrail logs API calls, not network traffic.

Correct answer & explanation
VPC Flow Logs
VPC Flow Logs capture IP traffic information for network interfaces, enabling analysis of traffic patterns and bottlenecks. AWS CloudTrail logs API calls, not network traffic. AWS Trusted Advisor provides best-practice checks but not detailed network analysis. AWS X-Ray traces application requests, not network-level traffic.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
VPC Flow Logs
Why this is correct
VPC Flow Logs capture IP traffic information for network interfaces, enabling analysis of traffic patterns and bottlenecks.
Related concept
Static NAT maps one inside address to one outside address.
AWS X-Ray
Why it's wrong here
AWS X-Ray traces application requests, not network-level traffic.
AWS Trusted Advisor
Why it's wrong here
Trusted Advisor provides best-practice checks but not detailed network analysis.
AWS CloudTrail
Why it's wrong here
CloudTrail logs API calls, not network traffic.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.
