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 has a multi-account AWS environment with hundreds of VPCs connected via a transit gateway. The network team needs to centrally monitor network traffic and detect anomalies such as unusual outbound data transfers. Which combination of services would provide the most scalable and cost-effective solution?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable VPC Flow Logs in each VPC, publish to Amazon S3, and use Amazon Athena to query logs from a central account
Option D is correct because VPC Flow Logs capture IP traffic metadata at scale, and publishing to Amazon S3 provides a cost-effective, durable storage layer. Using Amazon Athena to query the logs from a central account enables serverless, on-demand analysis across hundreds of VPCs without provisioning servers, making it both scalable and cost-effective for anomaly detection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use AWS Trusted Advisor to check for unusual traffic patterns
Why it's wrong here
Trusted Advisor does not provide granular flow analysis.
✗
Enable VPC Flow Logs in each VPC, publish to CloudWatch Logs, and create cross-account CloudWatch dashboards
Why it's wrong here
CloudWatch Logs can become expensive at scale.
✗
Use AWS Network Manager to monitor all VPCs and Transit Gateway attachments
Why it's wrong here
Network Manager provides topology but not detailed anomaly detection.
✓
Enable VPC Flow Logs in each VPC, publish to Amazon S3, and use Amazon Athena to query logs from a central account
Why this is correct
S3 is cost-effective for storage and Athena allows querying across accounts.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume CloudWatch Logs is the only or best destination for VPC Flow Logs, overlooking the cost and scalability advantages of S3 combined with Athena for large-scale, cross-account analysis.
Detailed technical explanation
How to think about this question
VPC Flow Logs capture fields such as source/destination IP, port, protocol, and packet/byte counts, but not payload data. When stored in S3, you can use Athena with partitioned Parquet tables to reduce query costs and improve performance; for example, partitioning by account, VPC, and date allows scanning only relevant data. A real-world scenario involves detecting data exfiltration by querying for high-volume outbound flows to unusual destination IPs or ports not typically seen in baseline traffic.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
