GDPS is a multi-site or single-site end to end application availability solution that provides the capability to manage remote copy configuration and storage subsystems (including IBM TotalStorage Enterprise Storage Server), to automate Parallel Sysplex operation tasks and perform failure recovery from a single point of control. A Coordinated Timing Network (CTN) is a collection of servers and Coupling Facilities that are time synchronized to a time value called Coordinated Server Time. STP (Server Time Protocol) introduces the concept of a Coordinated Timing Network (CTN), to meet two key goals of System z customers:Concurrent migration from an existing External Time Reference (ETR) network to a timing network using STP. Capability of servers that cannot support STP to be synchronized in the same network as servers that support STP (z9 EC, z9 BC, z990, z890) References: System z Parallel Sysplex Best Practices (January 2011)https://www-03.ibm.com/systems/z/advantages/gdps/faqs.html

Parallel Sysplex Advantages include incremental, granular growth with near linear scalability. With IBM's Parallel Sysplex technology, you can harness the power of up to 32 z/OS systems, yet make these systems behave like a single, logical computing facility. Incorrect Answers:B: On/Off Capacity on Demand (On/Off CoD) -This offering allows you to temporarily add additional capacity or specialty engines due to seasonal activities, period-end requirements, peaks in workload, or application testing. References: https://www-03.ibm.com/systems/z/advantages/pso/

Since 2007, the Eagle Team has worked with hundreds of customers, around the world, helping them examine the cost differences between System z and distributed options. Incorrect Answers:C: The IBM security tiger team was created to: 1. Articulate and sell IBM security solutions to "C-level" executives. In other words, align security solutions to business initiatives. 2. Cut across IBM brands. Tiger team members have deep knowledge of IBM security solutions from ISS, Rational, Tivoli, Websphere, etc. The focus is on customer needs rather than internal IBM organizational boundaries. 3. Act as security advocates within IBM.References: ftp://ftp.software.ibm.com/software/os/systemz/summit/handouts/Track_1_Collateral_-_Eagle_FAQs_Version_1A.pdfhttps://www.csoonline.com/article/2236493/cisco-subnet/ibm-s-security--tiger-team-.html

With the IBM z13 and IBM z13s servers, FICON channels are no longer restricted to the use of static SAN routing policies for ISLs for cascaded FICON directors. The z Systems servers now support dynamic routing in the SAN with the FICON Dynamic Routing (FIDR) feature. References: IBM z13 Technical Guide (May 2016), page 167

IBM Wave for z/VM is a provisioning and productivity management solution for managing virtual servers with z/VM. The IBM Wave interface provides an innovative approach to the task of managing one or multiple  IBM Z systems . Each system can be configured with one or many z/VM instances that can each run virtual Linux servers. References: https://www.ibm.com/support/knowledgecenter/en/SS6JTX/waveadmin/wave_intro_overview.html

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.

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/

Storage protection keys cannot be altered by application programs. There is no way, using the storage protection function, for a normal application program (not an authorized program) to protect part of its virtual memory from other parts of the application in the same address space. Note: Mainframe hardware has a storage protection function, which is normally used to prevent unauthorized alteration of storage. Storage protection is also used to prevent unauthorized reading of storage areas, although z/OS protects only small areas of storage this way.Storage protection works on 4K pages. It deals only with real memory, not virtual memory. When a page of virtual memory is copied from disk to a free page in main storage, z/OS also sets an appropriate storage protection key in that page of main storage. Storage protection was much more significant before multiple address spaces came into use. When multiple users and jobs were in a single address space (or in real memory in the days before virtual memory), protecting a user's memory from corruption (or inappropriate data peeking) was critical. With z/OS, the primary protection for each user's memory is the isolation provided by multiple address spaces. References: https://www.ibm.com/support/knowledgecenter/zosbasics/com.ibm.zos.zsecurity/zsecc_066.htm
