Amazon Exam SOA-C02 Topic 5 Question 90 Discussion

Actual exam question for Amazon's SOA-C02 exam

Question #: 90
Topic #: 5

A company hosts a web application on an Amazon EC2 instance. The web server logs are published to Amazon CloudWatch Logs. The log events have the same structure and include the HTTP response codes that are associated with the user requests. The company needs to monitor the number of times that the web server returns an HTTP 404 response.

What is the MOST operationally efficient solution that meets these requirements?

ACreate a CloudWatch Logs metric filter that counts the number of times that the web server returns an HTTP 404 response.

BCreate a CloudWatch Logs subscription filter that counts the number of times that the web server returns an HTTP 404 response.

CCreate an AWS Lambda function that runs a CloudWatch Logs Insights query that counts the number of 404 codes in the log events during the past hour.

DCreate a script that runs a CloudWatch Logs Insights query that counts the number of 404 codes in the log events during the past hour.

Show Suggested Answer

Suggested Answer: A

Using the ALB's RequestCount metric will allow the SysOps administrator to collect information about total requests for a 2-week period and determine when requests exceeded the threshold of 100 requests per second. Configuring a time range of 2 weeks and a period of 1 minute will ensure that the data can be accurately examined to determine peak traffic times and volumes.

I prefer option C, creating an AWS Lambda function to run a CloudWatch Logs Insights query. It gives more flexibility in monitoring the log events.

I agree with Gregoria. Creating a metric filter would be the easiest way to monitor the HTTP 404 responses.
