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?
Each HMC should be connected to both Service Processors on a separate private network.
The HMCs should share the same DHCP range.
Each HMC should be managed by PowerVC.
The HMCs should use the same subnet to connect to the service processors.
Correct answer: A
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.

A customer purchased a new E870. They would like to implement Linux-based infrastructure solutions such as:
email serving
Web serving
Network services
email filtering
Which of the following will help to establish a proof of concept implementation for these applications?
PowerCare
PowerVC Manager
PowerVM
Power POC Redbook
Correct answer: C
Explanation:
The PowerVM hypervisor supports multiple operating environments on a single system. Live AIX, Linux and IBM i VMs can be moved between servers, eliminating planned downtime. References: http://www-03.ibm.com/systems/power/software/virtualization/features.html

Which of the following RAS features is always enabled and functional on an E870 / E880, regardless of configuration?
System auto-restart
Dynamic Processor Sparing
Dynamic Memory Sparing
Processor Instruction Retry
Correct answer: D
Explanation:
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.Reference: IBM Power Systems E870 and E880 Technical Overview and Introduction (October 2014), page 150https://mrt.presalesadvisor.com/PowerStoragePDF/687.pdf
