[All AWS Certified Developer Associate Questions]

A company hosts a three-tier web application on AWS behind an Amazon CloudFront distribution. A developer wants a dashboard to monitor error rates and anomalies of the CloudFront distribution with the shortest possible refresh interval.
Which combination of slops should the developer take to meet these requirements? (Choose two.)

  • A. Activate real-time logs on the CloudFront distribution. Create a stream in Amazon Kinesis Data Streams.
  • B. Export the CloudFront logs to an Amazon S3 bucket. Detect anomalies and error rates with Amazon QuickSight.
  • C. Configure Amazon Kinesis Data Streams to deliver logs to Amazon OpenSearch Service (Amazon Elasticsearch Service). Create a dashboard in OpenSearch Dashboards (Kibana).
  • D. Create Amazon CloudWatch alarms based on expected values of selected CloudWatch metrics to detect anomalies and errors.
  • E. Design an Amazon CloudWatch dashboard of the selected CloudFront distribution metrics.

A and C is correct to me: https://aws.amazon.com/blogs/networking-and-content-delivery/cloudfront-realtime-logs/ It mentions shortest possible refresh interval so best to use the real-time logs

IS Kinesis Data Streams to deliver logs to Amazon OpenSearch Service? NO ofc it is Firehose

I would also go for A and C, however wording in C is misleading as it let me think KDS is delivering log directly OpenSearch while as you suggest KDS messages are picked by a Lambda that actually delivers them to OpenSearch

Selected Answer: AC
B) Eliminated - While exporting CloudFront logs to S3 and analyzing them with Amazon QuickSight is possible, this approach has a much longer delay because CloudFront access logs (standard logs) are delivered to S3 in batches, typically delayed by minutes or more. This is not suitable for real-time monitoring or detecting anomalies quickly

D) Eliminated: CloudWatch Alarms are used for triggering notifications (e.g., SMS, email) when metrics exceed thresholds, not for creating a real-time monitoring dashboard.

E) - Option E is valid but doesn't fully meet the requirement. Metrics alone cannot give detailed insights into every request/response for debugging errors.

I agree with you guys, I'll go for AC. First of all we need to send the cloud formation logs to a new Kinesis data stream by choosing the right partition key and shards number. Then, I think that this part is missing, we should use Kinesis Firehose before delivering to Elasticsearch. Once the data is managed by Elasticsearch, we can create the final dashboard with Kibana near realtime

https://aws.amazon.com/blogs/networking-and-content-delivery/cloudfront-realtime-logs/ With real-time logs, you can customize the information collected and where it gets delivered. The real-time logs are integrated with Amazon Kinesis Data Streams to enable delivery of these logs to a generic HTTP endpoint using Amazon Kinesis Data Firehose. Amazon Kinesis Data Firehose can deliver logs to Amazon S3, Amazon Redshift, Amazon Elasticsearch Service (Amazon ES), and service providers like Datadog, Datazoom, New Relic, and Splunk. Using these logs, you can create real-time dashboards, set up alerts, and investigate anomalies or respond to operational events quickly.
