AWS Certified Solutions Architect – Professional — Question 357

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."

Answer options

• 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.

Correct answer: B

Explanation

In Amazon ElastiCache, connecting to the cluster configuration endpoint is functionally identical to connecting to an individual cache node from the client application's perspective. The configuration endpoint simplifies management by resolving to the node endpoints automatically, supporting features like Auto Discovery without requiring different connection logic. Therefore, the application does not distinguish between the two types of connections during the initial handshake.
