Q11. Which feature is recommended to move memory resources from one LPAR to another?

A. Dynamic LPAR operation

B. Active Memory Sharing

C. Active Memory Expansion

D. Live Partition Mobility

Answer: B


Q12. A customer wants to save on IBM i licensing costs:

✑ They have three configurable processors and one IBM i license.

✑ LPAR1 is running IBM i with .5 CPU

✑ LPAR2 is running IBM i with .5 CPU

✑ LPAR3 is running AIX with 1 CPU

✑ All of the LPARs are uncapped.

✑ They want to limit the IBM i LPARs to using one core.

How can the customer enforce the limit and save on their IBM i licensing costs?

A. Put the IBM i LPARs in a shared processor pool with one core.

B. Put the AIX LPAR in a shared processor pool with one core.

C. Set the entitlement of each IBM i LPAR to "one"

D. Change the AIX partition to have .5 CPU entitlement.

Answer: C


Q13. Which of the following statements correctly describes a difference between the S814 and S824?

A. The S814 is a tower server and the S824 can be either a tower or rack mounted server

B. The S814 has one socket and the S824 has up to two sockets

C. The S814 can have one or two sockets and the S824 has four sockets.

D. The S814 uses 1U of rack space and the S824 uses 2U of rack space.

Answer: B


Q14. Which of the following are required in order to utilize Live Partition Mobility?

A. Dedicated processors PowerVM Enterprise Edition Virtual Ethernet

B. Dual VIO Servers PowerVM Enterprise Edition SAN attached disk two virtual processors

C. PowerVM Enterprise Edition SAN attached disk Virtual Ethernet

D. Dedicated processors Dual VIO Servers SAN attached disk Virtual Ethernet

Answer: A

Q15. A customer consolidated several environments running IBM i, Linux and AIX into an S824. Now the system's installed memory is insufficient. The customer believes that the Active Memory Expansion feature may resolve the memory issue.

Which of the following operating systems is capable of using the compression and decompression technology to resolve the issue?

A. AIX

B. IBM i

C. Red Hat

D. SUSE

Answer: B


Q16. Which statement is true regarding Power Systems being positioned as an open platform?

A. OpenStack management allows for a single HMC to provide centralized management across the whole private cloud.

B. CAPI allows clients to consolidate multiplatform workloads by attaching other manufacturer processors (like Intel or Oracle) on the servers.

C. PowerKVM allows clients to standardize on a single open source virtualization technology among RISC and x86 servers.

D. Linux on Power allows clients to transparently migrate workloads from Linux x86 servers via Live Partition Mobility.

Answer: C


Q17. A customer has a Power 740 with 16 cores and 64GB RAM, running an Oracle database. The server is attached to an EXP24S with 20 disks 300GB 10K RPM and has been experiencing performance issues. After an analysis there were some findings:

Average CPU usage for the database is 30% Average Memory usage is 60%

High I/O waits are being experienced, around 50% of total CPU

An Oracle sales representative ran a POC of an Exadata X4-2 Half Rack to help with the performance issues.

The performance on Exadata was better than the existing solution, so the customer called IBM, considering a migration to a new Oracle solution.

Which response is appropriate to defend the IBM solution?

A. Exadata X4-2 Half Rack has four servers with two sockets each. It should be compared with the performance of a POWER 770 which can also scale up to eight sockets. IBM can propose an upgrade scenario to even move partitions without downtime with LPM.

B. Exadata is a solution comprised of servers, disk storage, flash storage, networking and software. Your server is apparently fine, but there might be a problem with storage. IBM can propose a faster storage solution, allowing you to keep the server and optimize your costs.

C. Exadata might have run the Oracle database faster due to the fact that it is powered by Oracle SPARC T5 processors which were designed for Oracle software. On the other hand, other workloads will definitely run slower, so you should stick to the existing solution for a balanced performance across your environment.

D. Exadata is comprised of a cluster of servers connected by Infiniband. You are comparing this to a single server. IBM can propose a second server with an Infiniband network to address this issue.

Answer: B


Q18. What is the number of threads that can be processed for maximum throughput on a POWER8 core?

A. 12

B. 4

C. 8

D. 2

Answer: C


Q19. Shared Storage Pools (SSPs) are built on Cluster Aware AIX (CAA). What high-value function does this provide?

A. Automatic fall-over of LPARs between Power systems servers.

B. Synchronization of hdisk names in VIO Server across the cluster.

C. Thin provisioning of storage for client LPARs.

D. Zero-configuration implementation of NPIV storage.

Answer: C

B. Power VC

C. Power VP

D. Power SC

Answer: D
