Oracle Cloud Infrastructure 2020 Architect Associate — Question 30

With regard to Oracle Cloud Infrastructure Load Balancing service, which two actions will occur when a backend server that is registered with a backend set is marked to drain connections? (Choose two.)

Answer options

• A. All connections to this backend server are forcibly closed after a timeout period.
• B. Requests to this backend server are redirected to a user-defined error page.
• C. All existing connections to this backend sever will be immediately closed.
• D. All new connections to this backend server are disallowed.
• E. Connections to this backend server will remain open until all in-flight requests are completed.

Correct answer: D, E

Explanation

When a backend server is marked to drain connections, all new connections to that server are disallowed (D), while existing connections are maintained until they complete their requests (E). Options A, B, and C are incorrect because they imply forced disconnection or error redirection, which does not occur during the draining process.
