IBM C9030-644 Exam Actual Questions

Which of the following is the most critical factor of a Parallel Sysplex across multiple sites?

Correct Answer: A 🗳️
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)

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?

Correct Answer: D 🗳️
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.

An existing IBM z Systems client is concerned about the associated monthly software license costs. The clients own preliminary analysis suggested they can save money by off-loading workloads from their z Systems to x86 servers. The client is willing to work with IBM and they agreed to host an on-site workshop to discuss the matter.
Which is the most suitable resource needed to demonstrate to the client they might be making the wrong choice?

Correct Answer: D 🗳️
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.
