A customer recently purchased a Power E870 that includes redundant Service Processors, and would like to
implement dual HMCs.
What does IBM’s Best Practice documentation recommend?

A.
Each HMC should be connected to both Service Processors on a separate private network.

B.
The HMCs should share the same DHCP range.

C.
Each HMC should be managed by PowerVC.

D.
The HMCs should use the same subnet to connect to the service processors.

Explanation:
Using a redundant HMC configuration with your service processor setup requires a specific port configuration,
as shown in the figure below.

The HMC’s first Ethernet port, eth0, should be configured to be a Dynamic Host Configuration Protocol (DHCP)
server over a private network.
