Amazon SCS-C02 Exam - Topic 5 Question 39 Discussion

Actual exam question for Amazon's SCS-C02 exam

Question #: 39
Topic #: 5

A company is investigating an increase in its AWS monthly bill. The company discovers that bad actors compromised some Amazon EC2 instances and served webpages for a large email phishing campaign.

A security engineer must implement a solution to monitor for cost increases in the future to help detect malicious activity.

Which solution will offer the company the EARLIEST detection of cost increases?

ACreate an Amazon EventBridge rule that invokes an AWS Lambda function hourly. Program the Lambda function to download an AWS usage report from AWS Data Exports about usage of all services. Program the Lambda function to analyze the report and to send a notification when anomalies are detected.

BCreate a cost monitor in AWS Cost Anomaly Detection. Configure an individual alert to notify an Amazon Simple Notification Service (Amazon SNS) topic when the percentage above the expected cost exceeds a threshold.

CReview AWS Cost Explorer daily to detect anomalies in cost from prior months Review the usage of any services that experience a significant cost increase from prior months.

DCapture VPC flow logs from the VPC where the EC2 instances run. Use a third-party network analysis tool to analyze the flow logs and to detect anomalies in network traffic that might increase cost.

I recall VPC flow logs being important for security, but using a third-party tool for cost detection seems a bit indirect. Would that really help with early detection?

I feel like option C is too reactive. Daily reviews might miss sudden spikes, but it could still be useful for understanding trends.

I'm not entirely sure, but I think creating a Lambda function to analyze usage reports could take longer than just setting up an anomaly detection alert.

I remember we discussed AWS Cost Anomaly Detection in class. It seems like option B would give the earliest alerts, right?

Analyzing the usage report hourly, as suggested in option A, seems like it could be overkill and might not be the most efficient approach. I'm leaning towards option B as the most effective solution.

Option D with the VPC flow logs? That's just overkill. Unless you're dealing with a state-sponsored hacking group, I think that's a bit much.

I'm with Candidate 3 on this one. Who needs all the fancy monitoring when you can just eyeball the numbers yourself? Just don't forget to check it on your lunch break.
