Exam A

QUESTION 1Which scenario would provide the best opportunity to justify the RoCE Express feature?

A. Shared memory communication from a distributed Linux application to an MQ Linux guest on a z Systems server.

B. A z/OS WebSphere application that communicates to DB2 running on a z/OS LPAR on a separate z Systems server.

C. CICS to CICS communication between z/OS LPARs within the same z Systems server.

D. A Linux system running MQ on a z Systems server communicating to a z/OS MQ within the same server.

Correct Answer: ASection: (none)Explanation

Explanation/Reference:RoCE Express provides an RDMA capable network adapter providing access to RDMA over Converged Ethernet (RoCE). RoCE provides an optimized networkinterconnect for System z communications. Along with RoCE Express, z/OS provided a new RDMA based solution called Shared Memory Communications overRDMA (SMC-R). SMC-R is a sockets based solution providing transparent access to RoCE for TCP sockets applications over standard Ethernet. The IBM System z13 introduces the capability to share (virtualize) the 10GbE RoCE Express feature among multiple (up to 31) LPARs (or z/VM guest virtualmachines) using standardized PCIe virtualization (SR-IOV) technology.When RoCE Express is exploited by z/OS with SMC-R, the combined solutions provide two key value points:

Improved latency that can provide improved transaction rates for latency sensitive transactional based workloads, andLower CPU cost for workloads that transfer larger payloads (i.e. analytics, streaming, FTP, big data, data replication, web services, etc.)

QUESTION 35A z Systems Client Technical Specialist has a customer running z/OS 1.12 on a zEC12 machine. They want to get pricing for an upgrade to z/OS 2.2 for their newlypurchased z13 machine.

Which of the following can provide pricing for the z/OS operating system?

A. The IBM Washington System Center (WSC)

B. The Poughkeepsie Product Assistance Center (PPAC)

C. IBM Customer Service (ICS)


D. z Systems Digital Techline Center (zDTC)



QUESTION 36A customer is experiencing z/OS performance problems on their z13 while the system is taking a memory dump. Which chargeable z Systems feature couldprovide relief for this problem?

A. Flash Express

B. Simultaneous Multithreading

C. Single Instruction Multiple Data

D. zEnterprise Data Compression


Explanation/Reference:Typical simultaneous multithreading (SMT) implementations allow workloads from different control programs to use a compute core concurrently, but with variablecore capacity gains and thread execution slowdowns. The new IBM z13 platform implements SMT differently. At any point in time, a single control programmanages the entire core, giving each workload more repeatable core capacity for processing.
