True or False: "In the context of Amazon ElastiCache, from the application's point of view, connecting to the cluster configuration endpoint is no different than connecting directly to an individual cache node."
A.
True, from the application's point of view, connecting to the cluster configuration endpoint is no different than connecting directly to an individual cache node since, each has a unique node identifier.
B.
True, from the application's point of view, connecting to the cluster configuration endpoint is no different than connecting directly to an individual cache node.
C.
False, you can connect to a cache node, but not to a cluster configuration endpoint.
D.
False, you can connect to a cluster configuration endpoint, but not to a cache node.
B is correct

B. True, from the application's point of view, connecting to the cluster configuration endpoint is no different than connecting directly to an individual cache node.
B. True, from the application's point of view, connecting to the cluster configuration endpoint is no different than connecting directly to an individual cache node.
In the context of Amazon ElastiCache, the cluster configuration endpoint provides a single endpoint that represents the entire cache cluster. When an application connects to the cluster configuration endpoint, ElastiCache's automatic client-side routing feature directs the application's requests to the appropriate cache node within the cluster. From the application's perspective, it does not need to be aware of the individual cache nodes. The cluster configuration endpoint abstracts the underlying cache nodes, making it transparent to the application.
Therefore, the statement is true. From the application's point of view, connecting to the cluster configuration endpoint is no different than connecting directly to an individual cache node.
The configuration endpoint DNS entry contains the CNAME entries for each of the cache node endpoints. ref: https://docs.aws.amazon.com/AmazonElastiCache/latest/mem-ug/WhatIs.Components.html
ACD are wrong, but is B valid?
cluster configuration endpoint means cluster mode enabled, then there will be multiple shards, so connecting directly to an individual cache node means you can access only part of data but not all.
