C) ensures - The solution must minimize cost and administrative overhead

VPC flow logs capture information about the IP traffic going to and from network interfaces in a VPC. They provide details such as source and destination IP addresses, ports, and protocols. Publishing the VPC flow logs to a log group in Amazon CloudWatch Logs (Option C) allows for centralized and easy access to the flow log data. CloudWatch Logs Insights can be used to query the flow logs efficiently and identify the AWS resources that are generating the suspicious traffic. This solution minimizes cost by leveraging existing AWS services (CloudWatch Logs) and has lower administrative overhead compared to setting up custom streaming solutions (such as Amazon Kinesis) or deploying additional instances (as in Option A). Options A, B, and D introduce additional complexity and may have higher associated costs or administrative overhead compared to using CloudWatch Logs Insights for analyzing VPC flow logs.

C is the correct answer. VPC flow logs (with custom format to have "pkt-srcaddr" & "pkt-dstaddr" since it goes via NAT GW). Direct it to CloudWatch Logs, and use CW Logs Insights for querying and visualization.

C is the correct answer.

No doubt it is C, it is simple to implement (even temporarily) and is affordable.

Lowest cost

C is the simples

C. " The solution must minimize cost and administrative overhead."
