This exam has an Assessment Exam option: A9030-644 Assessment: IBM z Systems Technical Support V7

Assessment exams are web-based exams that provides you, at a cheaper costs, the ability to check your skills before taking the certification exam.
This assessment exam is available in: English, Japanese

Passing the exam does not award you a certification, and it is only used to help you assess if you are ready or not to take the certification exam.

You can register for it at Pearson VUE and it will provide you a score report, showing you how you did in each section.

All IBM certification tests presume a certain amount of “on-the-job” experience which is not present in any classroom or Web presentation. The recommended courses and links will help you gain the skill and product knowledge represented in the test objectives. They do�? not teach the answers to the test questions, and are not intended to do so. This information may not cover all subject areas in the certification test, or may contain more recent information than is present in the certification test. Taking these or any classes will not guarantee that you will achieve certification

QUESTION 1
A customer wants to concurrently add a central processor (CP) to a running z/OS LPAR, but has no reserved processors defined.
What must they do to add this additional processor to the LPAR?

A. Dynamically update and activate the new profile.
B. Invoke Change Running System on HMC/SE (Support Element) to add the CP to the running LPAR.Configure the CP online in z/OS.
C. Configure a CP online in z/OS.
D. Take down the LPAR and deactivate the current profile.Update the profile with the number of processors needed.Activate the new profile and IPL the LPAR.

Answer: D

Explanation:
With a proper PFT (Profile table entry) you can add CP, ZIIP, IFL, and ICSF processor to an LPAR.

QUESTION 2
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?

A. SMC-R
B. zEDC
C. OSA Express5S
D. High performance FICON

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.


QUESTION 3
What is hybrid cloud?

A. It is a compute cloud that mixes compute nodes with different CPU architectures.
B. It is an laaS cloud that provides instances with different operating systems.
C. It is an architecture that combines public and private clouds.
D. It is an laaS cloud that provides ephemeral storage only.

Answer: C

Explanation:
A hybrid cloud is an integrated cloud service utilizing both private and public clouds to perform distinct functions within the same organization.
