Amazon DVA-C02 Exam - Topic 1 Question 54 Discussion

Actual exam question for Amazon's DVA-C02 exam

Question #: 54
Topic #: 1

An application uses Lambda functions to extract metadata from files uploaded to an S3 bucket; the metadata is stored in Amazon DynamoDB. The application starts behaving unexpectedly, and the developer wants to examine the logs of the Lambda function code for errors.

Based on this system configuration, where would the developer find the logs?

AAmazon S3

BAWS CloudTrail

CAmazon CloudWatch

DAmazon DynamoDB

Show Suggested Answer

Suggested Answer: C

Amazon CloudWatch is the service that collects and stores logs from AWS Lambda functions. The developer can use CloudWatch Logs Insights to query and analyze the logs for errors and metrics. Option A is not correct because Amazon S3 is a storage service that does not store Lambda function logs. Option B is not correct because AWS CloudTrail is a service that records API calls and events for AWS services, not Lambda function logs. Option D is not correct because Amazon DynamoDB is a database service that does not store Lambda function logs.

I’m pretty confident it’s CloudWatch, but I guess we should rule out the other options just to be safe.

I’m a bit confused; could it be S3? I feel like I read something about logs being stored there too.

I remember practicing a question about Lambda logs, and I think it was definitely CloudWatch where we found them.

I think the logs for Lambda functions are stored in CloudWatch, but I'm not entirely sure.

Wait, I'm confused. If the issue is with the Lambda function, wouldn't the logs be in CloudTrail since that tracks all the AWS service activity? I'm not totally sure about this one.

Okay, I've got this. The Lambda function is the key here, so the logs will be in CloudWatch where AWS stores the logs for Lambda functions. Easy peasy!

I'm a bit unsure about this one. Is it possible the logs could be in DynamoDB since that's where the metadata is stored? I'll have to think this through.

Hmm, this seems straightforward. The Lambda function is processing files in an S3 bucket, so the logs should be in CloudWatch, right?

C) Amazon CloudWatch, no doubt. The developer should have known that - it's like going to the grocery store and forgetting to buy milk. Rookie mistake!

Hmm, I'd say C) Amazon CloudWatch is the way to go. The developer needs to stop relying on their crystal ball and start actually looking at the logs. Gotta love those Lambda functions, am I right?

C) Amazon CloudWatch, of course! That's where all the juicy Lambda logs live. I bet the developer has been napping on the job and forgot to check there. Tsk tsk.
