A. B. C. D.Answer - C.
The AWS Documentation mentions the following.
If you notice a significant increase in the number of HTTP 503-slow down responses received for Amazon S3 PUT or DELETE object requests to a bucket that has versioning enabled, you might have one or more objects in the bucket for which there are millions of versions.
When you have objects with millions of versions, Amazon S3 automatically throttles requests to the bucket to protect the customer from an excessive amount of request traffic, which could potentially impede other requests made to the same bucket.
To determine which S3 objects have millions of versions, use the Amazon S3 inventory tool.
The inventory tool generates a report that provides a flat file list of the objects in a bucket.
Option A is incorrect since this tool is used to monitor configuration changes.
Option B is incorrect since this tool is used to monitor API activity.
Option D is incorrect since this tool is used to give recommendations.
For more information on troubleshooting, please refer to the below URL-
https://docs.aws.amazon.com/AmazonS3/latest/dev/troubleshooting.htmlThe HTTP 503 error code indicates that the server is unavailable and cannot handle the request due to temporary overloading or maintenance. In this case, the high volume of PUT operations on the S3 bucket with versioning and encryption enabled could be causing the error.
To diagnose the issue, we need to identify the root cause of the error. Among the given options, AWS CloudTrail is the most suitable service to diagnose the issue.
AWS CloudTrail is a service that logs and monitors API calls made to AWS resources in your account. It provides event history of your AWS account activity, including actions taken through the S3 service. CloudTrail can help identify the cause of errors by providing detailed information about API calls made to S3 bucket, including who made the call, when it was made, and the response returned from the service. This information can help in identifying any error that may have occurred, and the frequency of the error.
AWS Config is a service that provides configuration history of your AWS resources, including S3 buckets. However, it does not provide information about API calls or error logs, which are required to diagnose the HTTP 503 error.
AWS S3 Inventory provides a scheduled report of the metadata of the objects and their corresponding version IDs for an S3 bucket. It is useful for generating business and auditing reports, but it does not provide information about API calls or error logs, which are required to diagnose the HTTP 503 error.
AWS Trusted Advisor is a service that provides recommendations for optimizing your AWS resources. It does not provide any information related to API calls or error logs.
Therefore, the most appropriate service to diagnose the HTTP 503 error in this scenario is AWS CloudTrail.
