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

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

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

Which of the following RAS features is always enabled and functional on an E870 / E880, regardless of configuration?

Correct Answer: D 🗳️
Processor Instruction Retry allows the system to recover from soft faults that otherwise result in outages of applications or the entire server.
Note: Within the processor core, soft error events might occur that interfere with the various computation units. When such an event can be detected before a failing instruction is completed, the processor hardware might be able to try the operation again by using the advanced RAS feature that is known as Processor
Instruction Retry.
