質問 2

In a two node HA cluster, two identical servers (same CPU, memory, and I/O card configurations) are designed to host the database tier of a 3-tier application. They are connected to a large external disk array through two fibre channel links. Under normal operations the production database is hosted on server A and a batch reporting tool is hosted on server B.
What are possible remedies for slow performance of the production database during non-failure operation? (Choose two).

（A）Activate available ICOD CPUs on server A.

（B）Implement PVlinks on both servers.

（C）Terminate WLM and Perfview middleware to free up additional CPU.

（D）Terminate batch reporting on server B to reduce disk array load.

What is the result of typing an entry for the SUBNET variable into the
Serviceguard package configuration script?

（A）The subnet going down will cause the package to fail to the alternate node.

（B）Serviceguard will use the value to determine which subnet mask to use when adding package IP addresses.

（C）Serviceguard will know which subnet to add the package IP address.

（D）It defines the "heartbeat" subnet for the Serviceguard Manager.
