Oracle WebLogic Server 12c: Advanced Administration II — Question 5

You need to ensure that when a failed admin server instance is restarted on another machine with a different IP address, the managed server is able to establish connection with the newly started instance.
Which technique will ensure that the connection can be made? (Choose the best answer.)

Answer options

• A. Configure a DNS name for AdminServer which maps to multiple IP addresses and specify this DNS name during managed server startup.
• B. Specify multiple admin server IP addresses during managed server startup.
• C. Use WLST to update the AdminServer IP address for a running managed server.
• D. Update the host file for a running managed server instance.

Correct answer: C

Explanation

Option C is correct because WLST allows for real-time updates to the AdminServer IP address, enabling immediate connection. Options A and B do not address the issue of IP address change during runtime. Option D would not take effect until the managed server is restarted, making it an ineffective solution for immediate reconnection.
