C. Intel encryption established parity with the IBM Z High Performance Bulk Data Encryption capability

D. IBM Pervasive Encryption leverages Full Disk Encryption (FDE) within their Intel servers

A client has a production data center and disaster recovery data center separated by more than 300 km.

What level of recovery can they achieve by using GDPS/GM (Global Mirror)?

A. RPO = 0, RTO = 0

B. RPO = 0, RTO > 0

C. RPO > 0, RTO = 0

D. RPO > 0, RTO > 0

In an environment with one IBM z14 and one z/OS LPAR, what component would contribute to higher availability?

A. Dual HMC setup

B. Three Phase Line cord

C. Parallel Sysplex

When planning a new disk unit to populate the reserved 16U space on a z14 ZR1, what could prevent installation?

A. 8U minimum and two power cords

B. Weight and power consumption

C. Height and maximum capacity

D. 6U minimum and Flash

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.

How was zBNA improved to support the latest driver level for the z14 server (GA2 in October 2018)?
