AWS Certified Solutions Architect – Professional — Question 149

What feature of the load balancing service attempts to force subsequent connections to a service to be redirected to the same node as long as it is online?

Answer options

• A. Node balance
• B. Session retention
• C. Session multiplexing
• D. Session persistence

Correct answer: D

Explanation

The correct answer is D, Session persistence, as it ensures that a user's session is consistently routed to the same server as long as it is available. Options A, B, and C do not specifically address the requirement of maintaining user sessions on the same node, making them incorrect in this context.
