Virtualization Technical Support for AIX and Linux - v2

Question 1

A customer is planning a new multi-tiered web based retail solution. The solution will be implemented on AIX, running on POWER7 based servers. Several options are being considered, including one enterprise class system, two mid-range systems, or several entry level systems.
Which of these documents will allow for an easy side-by-side comparison of the various models in the Power Systems range?

A. POWER7 Systems Facts and Features

B. AIX From Strength to Strength

C. Redpaper: IBM Systems Virtualization: Servers, Storage, and Software

D. IBM Power Systems Comparison Manual

Correct Answer: A

Question 2

A system with two WPARs is reaching the memory limits imposed on them. Both have
been set to a hard limit of 50%.
WPAR1 has a peak from 8am-10am of 70% memory resources WPAR2 has a peak from 2pm-6pm of 65% memory resources At peak times the system may kill processes which request more memory, as paging space
is exhausted.
What action would allow the two partitions to run efficiently at the same time?

A. Configure WPAR memory limits using shares, and then set a hard memory limit of 85%.

B. Use DLPAR to add additional memory to the global environment.

C. Configure the WPARs to run in passive mode.

D. Increase paging space by 20% for WPAR1 and 15% for WPAR2.

Correct Answer: A

Question 3

Which is the lowest edition of PowerVM that will permit redundant VIO Servers?

A. PowerVM Express Edition

B. PowerVM Standard Edition

C. PowerVM Enterprise Edition

D. PowerVM Basic Edition

Correct Answer: B

Question 4

Which of the following are valid outbound communication methods for Call Home using an HMC?

A. Local Modem VPN connection SSL Internet connection

B. SMTP Gateway connection Local Modem SSL Internet connection

C. SSL Internet connection VPN connection SNMP Gateway connection

D. SMTP Gateway connection VPN connection Local Modem

Correct Answer: A

Question 5

A Power Systems server is configured with a VIO server and several client LPARs. The administrator wants to use the padmin user to create a script, which will run on the VIO server to back it up to a remote system. Script output must be collected. How can this be achieved?

A. Create a backup script in /home/padmin
Run the script redirecting stdout and stderr to a log file

B. Create a backup script in /usr/ios/cli
Run "crontab -e root" to configure root to run it and redirect the output

C. Create a backup script in /usr/ios/cli
Use the "script" command in the shell program, to collect the output.

D. Create a backup script in /home/padmin
Use ssh from a remote system to run the script and capture the output on the remote
system.

Correct Answer: D

Question 6

What is a major benefit for using LHEA instead of an SEA?

A. 64 MAC addresses

B. Logical port throttling

C. 802.11Q support

D. Reduced networking configuration

Correct Answer: D

Question 7

An administrator must remove any installed efixes before attempting to install a new VIO Fix Pack. Which VIO command will advise if any VIO efixes are actually present?

A. lslpp

B. oem_platform_level

C. emgr

D. lssw

Correct Answer: D

Question 8

An architect is designing a new POWER7 implementation consisting of a VIO Server (VIOS) and 6 AIX partitions.
AIX partitions need to occasionally access a tape drive for restoration and backup of application data and tape access will not be required by more than on partition at any time.
The performance of the solution is not critical and the architect wants to keep the cost to a minimum.
Which of the following configurations will address the architects requirements?

A. Allocate a SAS tape drive to the VIOS partition.
Virtualize connections from the tape drive to the AIX clients using vSCSI.

B. Allocate a USB tape drive to the VIOS partition.
Virtualize connections from the tape drive to the AIX clients using NPIV

C. Allocate a FC tape drive to the VIOS partition.
Virtualize connections from the tape drive to the AIX clients using NPIV.

D. Allocate a SCSI tape drive to the VIOS partition.
Virtualize connections from the tape drive to the AIX clients using vSCSI.

Correct Answer: A

Question 9

An administrator is preparing to upgrade the environment's dual Virtual I/O servers (VIOS) from V1.2 to V2.1
What must considered in preparation for this upgrade?

A. All client LPARs must be shutdown as both VIO servers have to be upgraded to V2.1 at the same time.

B. The VIOS must be upgraded to the latest fixpack of V1.5 before upgrading to V2.1.

C. The only upgrade method that will be supported is using NIM because the current VIOS is lower than V1.3.

D. VIOS V2.1 requires AIX clients to be running AIX V6.1 at a minimum.

Correct Answer: B

Question 10

An LPAR requires more disk space so an application logging filesystem in datavg can be extended. There is an unused LUN, hdisk5, on the VIO Server.
Which command (or commands) will map the drive directly to the client?

A. mkvdev-vdev hdisk5 -vadaptervhost3 -devtest1_disk5

B. extendvg datavg hdisk5 mkvdev -vdev hdisk5 -vadapter vhost3 mklv -Iv testl disks -vdev vhost3

C. mkvdev-vdevvhost3-devhdisk5-vadaptertest1_disk5

D. extendvg datavg hdisk5 mklv-lv testl _disk5 datavg mkvdev -vdev testl _di sk5 -vadapter vhost3
