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.

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.

A customer purchased a new z14 3906-M02. They want the ability to add temporary CP capacity on short notice for a spike in production work.

What authorization feature should be configured?

A. OOCoD

B. CPE

C. CBU

D. CDP

A customer is interested in IBM LinuxONE as a platform for their new cloud-based application infrastructure. A sizing exercise has shown that one LinuxONE Emperor II machine (in LM2 configuration) is sufficient for their expected workload, but the customer is concerned about putting all the application workload on a single frame.

Which set of LinuxONE features can the technical specialist remind the customer about, to help to relieve their concern?

A. RAIM memory, Capacity on Demand, SIMD

B. Processor sparing, I/O redundancy, RAIM memory

C. Processor sparing, SIMD, CPACF

D. CPACF, I/O redundancy, Capacity on Demand

What IBM Z technology can be used to securely deploy application services using IBM Cloud Private, without having to change the application code to exploit the secure environment?

A. CPACF with Crypto Express

B. TKE Workstation

C. Crypto Express

D. Secure Service Container

A z13s customer is excited about the prospect of acquiring a z14 ZR1. They are very interested in the 16U Reserved component space within the z14 ZR1 CPC.

Which of the following is a limiting factor when proposing the 16U Reserved feature?

A. A maximum of two I/O drawers can be ordered.

B. The space is reserved for the IBM DS8882F.

C. Top Exit I/O cannot be ordered.

D. No three phase power is available.

Which IBM Z I/O adapter can connect to an IBM storage device?

A. OSA-Express6S GbE

B. Crypto Express6S

C. zHyperLink Express

D. ICA SR

What is Pervasive Encryption running z/OS on IBM Z?

A. Encryption of only data in-flight

B. Encryption of data in-flight and at-rest

C. Encryption of all types of data on IBM Z

D. Encryption of only data at-rest

A customer wants to replace two zEC12 processors in different locations with two z14 processors. The

customer has the following requirements:

Full redundancy within a z14 and in case of loss of one CPC.

Run 12 z/OS LPARs on each CPC.

Encryption requirements:

Some applications need SSL acceleration.

EP11 must be supported.

Pervasive Encryption must be supported.

Which of the following is the minimum hardware needed for each z14 to support the requirements?

A. 4 zHyperlink Express Ports, 8 Crypto Express 6S Features, CPACF enabled.

B. 4 Crypto Express 6S Features, CPACF enabled.

C. 2 TKEs, 6 Crypto Express 6S Features, CPACF enabled.

D. 8 Crypto Express 6S Features, CPACF enabled.

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?

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

B. Configure the zERT collection correctly on the Sysplex Distributor hosts.

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

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