Oracle WebLogic Server 12c: Administration I — Question 16

Identify two reasons for defining machines and assigning servers to them in WebLogic Server. (Choose two.)

Answer options

• A. A machine can be the proxy to a cluster.
• B. A machine definition is required to configure the Node Manager.
• C. To reference an instance of WebLogic Server, you must know its machine and port.
• D. A machine is a required organizational unit. A domain contains machines and machines contain servers.
• E. WebLogic Server uses server machine assignments to help it choose servers in a cluster on which to replicate session state.
• F. A machine's Cluster Weight attribute may be used by load balancers to help them determine how often to send requests to servers assigned to that machine.

Correct answer: B, E

Explanation

Option B is correct because a machine definition is essential for configuring the Node Manager, which manages server instances. Option E is also correct as WebLogic Server uses these assignments to effectively manage session state replication across servers in a cluster. The other options, while related to machines and clusters, do not directly address the reasons for defining machines and assigning servers.
