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.

Explanation:
This 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. In the process of connecting
to cache nodes, the application resolves the configuration endpoint’s DNS name. Because the
configuration endpoint maintains CNAME entries for all of the cache nodes, the DNS name
resolves to one of the nodes; the client can then connect to that node.
