Oracle Cloud Infrastructure 2019 Developer Associate — Question 18

Which two will occur when a backend server that is registered with a backend set is marked to drain connections? (Choose two.)

Answer options

• A. It disallows new connections to that back-end server.
• B. It keeps the connections to that instance open and attempts to complete any in-flight requests.
• C. It redirects the requests to a user-defined error page.
• D. It immediately closes all existing connections to that instance.
• E. It forcibly closes all connections to that instance after a timeout period.

Correct answer: A, D

Explanation

The correct answer is A and D because marking a backend server to drain connections prevents new connections and immediately closes all existing ones. Option B is incorrect as it suggests keeping connections open, while options C and E do not represent the default behavior of draining connections.
