Demo Questions
Question 1
The IBM account has requested an analysis to review a zEC12 upgrade to a z13.
What analysis tool is required to ensure the z13 machine channels are reviewed to meet the customer’s FICON Express 16S performance requirements?
- zPCR
- zCP3000
- zBNA
- zSCON
Correct answer: A
Explanation:
The IBM Processor Capacity Reference for z Systems (zPCR) tool has been changed to support the new z/OS workload categories. Note: Capacity Planning Tool (GA Level) for z13 and zBX Model 4 include zPCR, zTPM, zCP3000, zBNA, zSoftCap, zTPM, zSCON.Incorrect Answers:B: The zCP3000 VM Extract Utility (CP3KVMXT) reads CP Monitor data and generates an Enterprise Data File (EDF) of system and workload related measurements for input into zCP3000. It supports VM running as native or in a partition. It can be used to model interactive VM workloads or workloads under guest operating systems such as Linux.C: IBM z Systems Batch Network Analyzer (zNBA) can be used to analyze client-provided System Management Facilities (SMF) records to identify jobs and data sets that are candidates for zEDC compression, across a specified time window, typically a batch window.D: zSCON is used for OEM Server Consolidation onto System z.

Question 2
You are leading a planning meeting for a disaster recovery (DR) test when a high-level company executive drops in to ask why the company should spend so much time and money on disaster recovery.
What is the most accurate response to this non-technical question?
- A company should plan for business resiliency because it doesn’t want to fail a tax audit.
- A company should plan for business resiliency to address future growth.
- A company should plan for business resiliency due to the risk of fraud.
- A company should plan for business resiliency in light of the (actual or potential) money that could be lost in case of an outage.
Correct answer: D
Question 3
Which functionality provides a high speed networking link for sharing data using server-to-server communications, at low latency, and with lower CPU overhead than traditional TCP/IP communications?
- SMC-R
- zEDC
- OSA Express5S
- High performance FICON
Correct answer: A
Explanation:
With SMC-R, System z network capability takes a new leap, strengthening performance for sharing data and reducing data transmission network overhead. The new System z® RDMA over Converged Ethernet (RoCE) feature — 10GbE RoCE Express—enables industry-standard RDMA capability on the System z platform. As an RDMA-capable network interface card (RNIC), it can transfer data using direct memory-to-memory communication, reducing the CPU overhead of the networking software stack. SMC-R provides application transparent exploitation of this new RoCE feature reducing the network overhead and latency of data transfers, effectively offering the benefits of optimized network performance across processors. This breakthrough also lowers the CPU cost associated when moving large amounts of data. Incorrect Answers:B: Using the zEnterprise Data Compression (zEDC) enhancements.This enhancement allows storage administrations to exploit zEnterprise data compression (zEDC) for non-VSAM compressed format data sets. Unlike previous compression types, no separate dictionary needs to be created, as zEDC compression hides the dictionary in the data stream. A new dictionary starts in each compression unit. The system can decompress the segment as is. C: OSA-Express is an integrated hardware feature that provides direct connection to clients on local area networks (LANs). The OSA-Express feature plugs into an I/O slot just like a channel card. Fiber-optic cable connects the OSA-Express feature to the network.References: https://www-01.ibm.com/software/network/commserver/SMC/ With SMC-R, System z network capability takes a new leap, strengthening performance for sharing data and reducing data transmission network overhead.
