Which of the following cannot be used to manage Amazon ElastiCache and perform administrative tasks?

Explanations:

AWS SDKs allow developers to interact programmatically with AWS services, including Amazon ElastiCache, enabling management and administrative tasks.

Amazon S3 is a storage service and does not provide capabilities for managing or performing administrative tasks on Amazon ElastiCache.

The ElastiCache CLI allows users to manage ElastiCache clusters and perform various administrative tasks directly from the command line.

AWS CloudWatch is used for monitoring and logging AWS resources, including ElastiCache, allowing users to manage their performance and operational health.
