IBM IBM Certifications C1000-038 Questions & Answers

• Question 21:

  A customer purchased a z14 M02 (two drawer) 710 with 1TB of active memory and 2TB of pre-planned memory installed. They are planning for the release of a new product which will require, for several days, additional processor and memory capacity. They have a CIU (Customer Initiated Upgrade) contract already in place.

  Utilizing CIU and OOCoD (On Off Capacity On Demand), which of the following options will satisfy the customer's requirement?

  A. Temporarily activate twice the amount of owned processor capacity that is present but not characterized in the two drawers, and purchase increments of the pre-planned memory up to the amount that is present in the two drawers.

  B. Temporarily activate all of the additional processor capacity that is present but not characterized in the two drawers, and purchase increments of the pre-planned memory up to the amount that is present in

  the two drawers.

  C. Temporarily activate all of the processor capacity that is present but not characterized in the two drawers, and temporarily add all the additional pre-panned memory increments up to the amount of that is present in the two drawers.

  D. Temporarily activate twice the amount of owned processor capacity that is present but not characterized in the two drawers, and temporarily add up to twice the amount of the active memory using the pre-planned memory in the two drawers.

  Correct Answer: A

• Question 22:

  B. CPE

  C. CBU

  D. CDP

  Correct Answer: A

• Question 25:

  A customer is running a z14-702 with two zIIPs. They started noticing that the zIIP utilization during peak hours was averaging about 85% due to a new Java application. After examining RMF, they realized that during these periods, much zIIP eligible work was overflowing to the general purpose CPs, causing them to also run over 90% for considerable periods of time.

  They have a limited budget for new equipment. After reading about Simultaneous Multithreading (SMT), they think they can solve their problem by turning SMT on instead of purchasing either another GP, a zAAP, or a third zIIP in order to get more throughput.

  What must they consider before making the decision to turn on SMT or purchasing another processor?

  A. Adding a third General Purpose processor and a zIIP is the only solution that will eliminate both problems.

  B. Adding a zIIP cannot be done because a 702 with two General Purpose CPs can only have two zIIP Processors.

  C. If there is a large amount of Java work, adding a zAAP would substantially reduce the zIIP utilization and free up the zIIPs to handle workloads that are specifically zIIP eligible.

  D. Turning on SMT, while providing more zIIP throughput, could affect the zIIP intensive workloads performance negatively.

  Correct Answer: A

• Question 26:

  A client with a fully depreciated production zBC12 would like to upgrade to a z14 ZR1 of equal capacity. At the same time, they would complete a data center move to a location across the country requiring minimal downtime.

  Which of the following would typically be the most economical way to migrate them from the zBC12 to the z14 ZR1, accommodating the data center move while providing the least amount of downtime?

  A. Purchase a net new z14 ZR1 for installation in the new data center.

  B. MES the zBC12 to a z14 ZR1 located in the new data center.

  C. MES zBC12 to z14 ZR1 in the current location; then move the z14 ZR1 to the new location.

  D. Perform a Migration Offering from zBC12 to the z14 ZR1 in the new data center.

  Correct Answer: A

• Question 27:

  Which of the following is used to consolidate host channels on an IBM z14?

  A. CFSIZER tool

  B. FICON Aggregation analysis

  C. Fit for Purpose study

  D. zBNA tool

  Correct Answer: D

  Which components of the database as a service solution should be presented to this future client?

  A. LinuxONE, Linux, and MySQL DB

  B. LinuxONE, Linux, and Db2 DB

  C. LinuxONE, Linux, and Oracle DB

• Question 29:

  What can a general purpose CP on the LinuxONE Rockhopper II or Emperor II be used for?

  A. IBM Db2 Analytics Accelerator (IDAA)

  B. Geographically Dispersed Parallel Sysplex (GDPS)

  C. Secure Service Container (SSC)

  D. Dynamic Provision Manager (DPM)

  Correct Answer: B

• Question 30:

  A client is concerned about their x86 database I/O response time. Further analysis reveals significant I/O wait delay.

  How is the IBM Z architecture better equipped than the x86 architecture to address this specific issue?

  A. It leverages the VRIO (Vector I/O) to control I/O wait.

  B. It leverages the I/O subsystem to manager I/O wait.

  C. It leverages the VIO (Virtual I/O) to eliminate I/O wait.

  D. It leverages zIIP processors to speed-up I/O wait.

  Correct Answer: C
