Demo Questions
Question 1
Which of the following is the most critical factor of a Parallel Sysplex across multiple sites?
- Coordinated Timing Network (CTN)
- Sysplex Distributor
- Network bandwidth
- Network latency
Correct answer: A
Explanation:
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 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.

Question 2
A banking customer is running a Parallel Sysplex with two z13 systems. Each server is configured with 100 CPs, 20 zllPs, 10 ICFs and 11 IFLs.
Both systems are currently running over 85% utilization business-critical workloads. The customer needs additional capacity for future growth.
Which solution will prevent a negative impact to the business?
- Upgrade the systems sequentially.
- Apply CoD processors to the systems.
- Perform a concurrent upgrade.
- Add a third machine to the sysplex.
Correct answer: D
Explanation:
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.

Question 3
A customer is planning to use a z13s with two CPC drawers as an external coupling facility.
What is the maximum number of Internal Coupling Facility (ICF) processors that can be used?
- 12
- 20
- 10
- 24
Correct answer: C
