Question 2 Single choice

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?

  1. A

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

  2. B

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

  3. C

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

  4. D

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

Question 5 Single choice

A customer starts using z/OS Encryption Readiness Technology (zERT) to gather knowledge about the state of encrypted network traffic in their system. They also use Sysplex Distributor, so there is TLS-encrypted traffic routed through the distributor systems to application hosts. The distributor systems also host TLS-encrypted TN3270 services for the network.

They started gathering data from the Sysplex Distributor hosts, since encrypted traffic is routed through those systems. A large number of encrypted TCP sessions seem to be missing from the customer's analysis.

What does the customer need to do to gather full analysis data?

  1. A

    Start gathering zERT data on all z/OS systems in their environment.

  2. B

    Configure the zERT collection correctly on the Sysplex Distributor hosts.

  3. C

    Move the collection of data to the z/OS application data hosts.

  4. D

    Move the collection of data to the network routers neighboring the z/OS systems.

Show answer and explanation

Correct answer: D

Question 6 Single choice

A customer has a new z14 and would like Container Pricing for the z/OS system based on their monthly usage.

How will the pricing be based through Resourcelink tables?

  1. A

    MIPS

  2. B

    LSPR

  3. C

    ITRR

  4. D

    MSU

  2. B

    CPE

  3. C

    CBU

  4. D

    CDP

Show answer and explanation

Correct answer: A

Question 8 Single choice

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?

  1. A

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

  2. B

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

  3. C

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

  4. D

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