Question #1
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?
  1. A
    Each HMC should be connected to both Service Processors on a separate private network.
  2. B
    The HMCs should share the same DHCP range.
  3. C
    Each HMC should be managed by PowerVC.
  4. D
    The HMCs should use the same subnet to connect to the service processors.

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.

Question #2
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?
  1. A
    PowerCare
  2. B
    PowerVC Manager
  3. C
    PowerVM
  4. D
    Power POC Redbook

Correct Answer:
C
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.

Question #3
Which of the following RAS features is always enabled and functional on an E870 / E880, regardless of configuration?
  1. A
    System auto-restart
  2. B
    Dynamic Processor Sparing
  3. C
    Dynamic Memory Sparing
  4. D
    Processor Instruction Retry

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.

Question #4
Which of the following is a feature in PowerVM?
  1. A
    Hard capping of virtual machines
  2. B
    Processor Micro-Threading
  3. C
    Active Memory Expansion
  4. D
    SR-IOV adapter support

Correct Answer:
A
PowerVM supports Shared processor pools, which have the following benefit:
Processor resources for a group of VMs can be capped, reducing software license costs

Question #5
Which IBM product is used to build, deploy, and manage infrastructure?
  1. A
    PowerVM
  2. B
    PowerVP
  3. C
    PowerVC Manager
  4. D
    PowerSC Manager

Correct Answer:
A
PowerVM provides a secure and scalable server virtualization environment for AIX, IBM i and Linux applications built upon the advanced RAS features and leading performance of the Power Systems platform.
Incorrect Answers:
B: PowerVP provides real time performance information which identifies performance bottlenecks using a graphical display showing the performance health of virtualized workloads mapping VMs to physical resources.
C: PowerVC is designed to improve administrator productivity and simplify the cloud management of VMs on Power Systems servers.
D: IBM PowerSC provides a security and compliance solution optimized for virtualized environments on Power Systems servers.
