Which four statements regarding IPMI configuration are true?

During the installation of Oracle Grid Infrastructure 11.2, it is possible to incorporate failure
isolation support by using Intelligent Platform Management Interface (IPMI).
Which four statements regarding IPMI configuration are true?

A.
Each cluster member node requires a Baseboard Management Controller (BMC), which runs a
firmware compatible with IPMI version 1.5.

B.
The ethernet port on each cluster node used by BMC must be connected to the IPMI
management network.

C.
Each node in the cluster must have an IPMI driver installed.

D.
The cluster requires a dedicated network specifically for IPMI.

E.
If you intend to use IPMI, you must provide an administration account username and password
when prompted during installation.

Explanation:
2.13.1 Requirements for Enabling IPMI
You must have the following hardware and software configured to enable cluster nodes to be
managed with IPMI:
Have IPMI Configuration completed and have IPMI administrator account information
If you intend to use IPMI, then ensure BMC interfaces are configured, and have an administration
account username and password to provide when prompted during installation.
For nonstandard installations, if you must change configuration on one or more nodes after
installation (for example, if you have different administrator usernames and passwords for BMC
interfaces on cluster nodes), then decide if you want to reconfigure the BMC interface, or modify
IPMI administrator account information after installation.
