As load increases and database connections scale, RDS Proxy helps:

Pool and share database connections

Improve application scalability

Reduce database resource contention

From the Amazon RDS Proxy Documentation:

RDS Proxy manages thousands of concurrent database connections and reduces connection overhead.

It is particularly useful for Aurora Multi-AZ clusters under high load.

❌ Why the other options are incorrect:

A: Increasing IOPS addresses disk throughput, not connection handling.

C: Monitoring does not solve connection issues.

D: Performance Insights provides visibility, not connection pooling.

 Objective:

Publish VPC flow logs to Amazon CloudWatch Logs.

 Root Cause:

VPC flow logs require an IAM role with permissions to create log groups, log streams, and write logs to CloudWatch Logs.

If the logs:CreateLogGroup permission is missing, the flow log cannot create the required log group, and logs will not appear in CloudWatch.

 Solution Implementation:

Step 1: Verify the IAM role attached to the VPC flow logs.

Step 2: Add the following permissions to the IAM policy:

logs:CreateLogGroup

logs:CreateLogStream

logs:PutLogEvents

Step 3: Update the IAM role policy and retry creating flow logs.

 AWS References:

VPC Flow Logs Permissions:Permissions for VPC Flow Logs

 Why Other Options Are Incorrect:

Option B: logs:CreateExportTask is for exporting logs from CloudWatch to S3, not for creating log groups.

Option C: IPv6 addresses do not impact the publishing of flow logs to CloudWatch Logs.

Option D: VPC peering does not block flow log functionality.

Amazon Macie is a security service designed to help organizations find, classify, and protect sensitive data stored in Amazon S3. Amazon Macie uses machine learning to automatically discover, classify, and protect sensitive data in Amazon S3. Creating a discovery job with the managed data identifier will allow Macie to identify sensitive personal information in the S3 files and classify it accordingly. Enabling AWS Config and Amazon GuardDuty will not help with this requirement as they are not designed to automatically classify and protect data.
