Amazon DOP-C02 Exam - Topic 3 Question 19 Discussion

Actual exam question for Amazon's DOP-C02 exam

Question #: 19
Topic #: 3

A company's application runs on Amazon EC2 instances. The application writes to a log file that records the username, date, time: and source IP address of the login. The log is published to a log group in Amazon CloudWatch Logs

The company is performing a root cause analysis for an event that occurred on the previous day The company needs to know the number of logins for a specific user from the past 7 days

Which solution will provide this information'?

ACreate a CloudWatch Logs metric filter on the log group Use a filter pattern that matches the username. Publish a CloudWatch metric that sums the number of logins over the past 7 days.

BCreate a CloudWatch Logs subscription on the log group Use a filter pattern that matches the username Publish a CloudWatch metric that sums the number of logins over the past 7 days

CCreate a CloudWatch Logs Insights query that uses an aggregation function to count the number of logins for the username over the past 7 days. Run the query against the log group

DCreate a CloudWatch dashboard. Add a number widget that has a filter pattern that counts the number of logins for the username over the past 7 days directly from the log group

Show Suggested Answer

Suggested Answer: C

To analyze and find the number of logins for a specific user from the past 7 days, a CloudWatch Logs Insights query is the most suitable solution. CloudWatch Logs Insights enables you to interactively search and analyze your log data in Amazon CloudWatch Logs. You can use the query language to perform queries that contain multiple commands, including aggregation functions, which can count the occurrences of logins for a specific username over a specified time period. This approach is more direct and efficient than creating a metric filter or subscription, which would require additional steps to publish and sum a metric.Reference:AWS Certified DevOps Engineer - Professional,CloudWatch Logs Insights query syntax,Tutorial: Run a query with an aggregation function,Add or remove a number widget from a CloudWatch dashboard.

I recall something about using subscription filters, but I can't remember if that was for real-time processing or for this kind of analysis.

I'm not entirely sure, but I feel like metric filters could be useful here. Was it option A or B that involved creating a metric filter?

This seems straightforward enough. I think I'll go with option D and create a CloudWatch dashboard with a number widget that filters the log data directly. That way, I can easily see the login count for the specific user without having to write a custom query.

I'm a little confused by the difference between options A and B. Both seem to involve creating some kind of metric, but I'm not sure which one is more appropriate for this use case. I'll need to read through the details of each option carefully before deciding.

Okay, I've got this. The key here is that we need to aggregate the login data over the past 7 days, and option C with the CloudWatch Logs Insights query is the best way to do that. I'll make sure to include the appropriate time range in the query.

Hmm, I'm a bit unsure about this one. The question mentions a log group in CloudWatch Logs, so I'm thinking option A or B might be the way to go, but I'm not sure which one would be better. I'll need to review the differences between metric filters and subscriptions.

I was leaning towards D, but now I think C is the better choice. Creating a dashboard just to display the login count seems a bit excessive. The Logs Insights query is more efficient.

Yeah, C is the way to go. The other options involve creating additional metrics or dashboards, which might be overkill for this particular use case. The Logs Insights query is a nice, clean solution.
