Partitions—Reports—Host Connections Summary
Partitions—Reports—Orphaned Cartridge Report
Partitions—Reports—Partition Details
Partitions—Reports—Partition Summary
Reference: StorageTek SL500 Modular Library System, Partition Report Screens

QUESTION 2
What ACSLS command would change a cap priority?

A. set cap priority 5 0, 0, 1
B. define cap priority 5 0,0,1
C. change cap priority 5 0, 0, 1
D. lock cap priority 5 0, 0, 1

Answer: A

Explanation: A: The set cap priority command sets a CAP's automatic selection priority.
Format
set cap priority cap_priority cap_id
Reference: StorageTek ACSLS, Automated Cartridge System Library Software , set cap priority

QUESTION 3
Using ACSLS, how would you delete a tape pool?

A. Set scr off and delete the pool
B. Remove all data tapes and delete the pool
C. Delete pool 0 and all empty pools will delete automatically
D. Remove all volumes from the pool and then delete it

Answer: A

Explanation: Use the delete pool command to delete empty scratch pools. If a pool
contains scratch cartridges, you must reassign these cartridges to another
pool before deleting the first pool. If a scratch cartridge is mounted, it becomes
a data cartridge but remains in its scratch pool. Use the set scratch off
command to reassign the data cartridge to the common pool.
Reference: StorageTek ACSLS, Automated Cartridge System Library Software , delete pool

QUESTION 4
Which connectivity option is available only in an SL8500 library complex?

A. single TCP/IP connectivity
B. dual TCP/IP connectivity
C. multi TCP/IP connectivity

Answer: B

Explanation: The SL8500 library uses TCP/IP protocol over an Ethernet physical interface to manage and communicate with the library. This interface enables both enterprise-level (HSC) and open system platforms (ACSLS) to connect to and communicate with the SL8500. There are two separate Ethernet connections on the HBC card for host to library communications—Ports 2A and 2B.
* Port 2A provides the Dual TCP/IP host connection—this is an optional feature for SL8500 libraries..
* Port 2B provides the primary connection for host communications—this is the standard connection for SL8500 libraries.

Reference: StorageTek StreamLine SL8500, modular library system, Host Interfaces

QUESTION 5
Where are the messages written when a pool gets below the low water mark?

A. acsss_event.log
B. pool_error.log
C. hardware_event.log
D. Doesn't write an error message

Answer: A

Explanation: low_water_mark is the low volume warning threshold. If the scratch cartridge count falls below this threshold, ACSLS logs a warning message in the event log.
Valid values are 0 to 231-1. The default is 0.

Note: The ACSLS event log is the first stop for useful information in the event of problems with your library operation. This log contains information about library events, status changes, and errors. All sub-components within ACSLS will report events to the acsss_event.log by sending messages to a process called the event logger. The standard event log, which is automatically created when ACSLS is installed, is contained in the file $ACS_HOME/log/acsss_event.log and where $ACS_HOME is usually
/export/home/ACSSS/.

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.
References: IBM z13 and IBM z13s Technical Introduction (March 2016), page 90

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

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.
