A. (8) drives and a split backplane
B. (12) drives and a split backplane
C. (12) drive , do not split backplane
D. (8) SAS drives and an auxiliary controller
Answer: D
Q14. What is the main function of the P0WER8 CAPI feature?
A. It improves memory bandwidth.
B. It improves cache coherency.
C. It increases the clock frequency speed.
D. It connects auxiliary processors such as GPUs.
Answer: C
Q15. A customer wants to use SAN Flash Copy with Geographic Mirroring to synchronize an IBM i application between two sites. It is required that the application can be halted and moved to the remote system without disrupting other applications.
Which of the following describes a required application characteristic to support these requirements?
A. The application code and data must reside in an IBM i user Auxiliary Storage Pool (ASP).
B. All the application data objects must be defined to remote journaling.
C. The application code and data must reside in the IBM i system Auxiliary Storage Pool (ASP).
D. The application code and data must reside in an IBM i Independent Auxiliary Storage Pool (ASP).
Answer: D
Q16. 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
Q17. Which of the following statements is true regarding CAPI?
A. CAP1 allows for adapters like FPGAs and GPUs to bypass the CPU and access the memory directly, allowing for faster data access and reduced CPU utilization
B. CAPI enabled servers use general purpose accelerators that increase the processor clock without compromising stability and RAS.
C. CAPI allows supported third party CPUs (Oracle, Intel, AMD, etc.) to be installed to speed up processing of specific workloads such as big data, compression or Java.
D. CAPI is designed for High-Performance Computing only. Commercial workloads cannot benefit from CAPI acceleration
Answer: C
Q18. 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
Q19. 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
Q20. A customer is interested in migrating Little Endian (LE) Linux workloads to POWERS servers running Power KVM.
