Question 6 Single choice

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.

Question 10 Single choice

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.
