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?
Create a backup script in /home/padmin Run the script redirecting stdout and stderr to a log file
Create a backup script in /usr/ios/cli Run "crontab -e root" to configure root to run it and redirect the output
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.
Create a backup script in /usr/ios/cli Use the "script" command in the shell program, to collect the output.
An administrator has configured a system to provide resilient networking through the use of SEA failover. The administrator wants to know if the SEA for one VIO server, ent10, is the active adapter. Which of the following commands could the administrator use to determine the status of ent10?
netstat -cdlistats ent10
During a Live Partition Mobility action, the network on one of the MSPs fails and an error is shown. Checking the HMC, the administrator sees the following:
What is the current state of the source LPAR?
Running and accessible as normal
Running but inaccessible via network
Running but with read-only SAN connectivity
Running but in a restricted state
An administrator has a Power 720 with 64GB of memory and Active Memory Expansion (AME). An LPAR has only 10GB of memory available and an application has been sized at 15GB of memory. The administrator runs amepat to determine an efficient expansion factor. Based on the output, an expansion factor of 1.6 has been chosen. How should this be configured in the LPAR?
Enter 16GB as 'desired', enter 1.6 in the Active memory expansion factor field.
Enter 10GB as 'desired', enter 1.6 in the Active memory expansion factor field.
Enter 10GB as 'desired' and modify/etc/ame.conf with AME_RATIO=1.6.
Enter 16GB as 'desired' and modify/etc/ame.conf with AME_RATIO=1.6.
How can SMT be temporarily disabled at the next boot of a Linux LPAR?
Update/proc/cpuinfo special device file.
Use the ppc64_cpu command.
Set linux smt-enabled=off at the boot: prompt.
Use the smtclt command.
What configuration change must be made on a Power Systems server to allow a Host Ethernet Adapter (HEA) to be used as part of a Shared Ethernet Adapter (SEA) on a Virtual I/O Server?
The HEA port must be set to promiscuous mode.
Set the HEA Port Group Multi-Core Scaling value to 1.
Enable 802.11Q protocol on the HEA port that will be assigned to the SEA.
Set the "Allowable VLAN IDs" to the PVID of the VIOS Virtual Ethernet Adapter.
Which of the following is required when configuring an LPAR that will later be used for Live Partition Mobility?
All physical I/O must be allocated as "Desired" in LPAR properties
Virtual Fibre Channel adapters must be marked as "Desired".
Virtual Ethernet adapters must be configured as EtherChannels.
Virtual SCSI adapters must be marked as "Desired".
A company wants to migrate an existing x86 Linux CRM and database environment from a large cluster of servers to a Power 750 server. How can they perform this with minimal costs and rapid deployment?
Create virtual LPARs with Linux and migrate the applications, porting the x86 applications to Power.
Create virtual LPARs with Linux and migrate the applications to IBM Middleware for Linux.
Create virtual LPARs with Linux and install the applications using PowerVM Lx86.
Create virtual LPARs with Linux and install the applications using VMware.
As a result of an acquisition, an administrator is planning to consolidate some single-LPAR POWER6 520 servers onto an existing POWER7 server. The administrator is attempting to make these 520 systems HMC-managed. The network connection between the 520 system and an existing operational HMC have been verified and checked. However the POWER6 machines fail to appear on the HMC panels. What is the most likely resolution for this issue?
The POWER6 boxes need to be reset back to factory defaults.
The Flexible Service Processor (FSP) needs to be reset on each POWER6 520.
Upgrade to either PowerVM Standard or Enterprise edition.
Power cycle the physical system.
A system is being designed with redundant VIO servers which will each support networking and storage for 17 client partitions. What is the minimum quantity of adapters needed to support the networking and storage requirements?
An administrator would like to create AIX 5.2 Workload Partitions (WPARs) on a new POWER7 system. Which of the following is the minimum needed to achieve this?
PowerVM Enterprise Edition AIX 5.2 Workload Partitions for AIX
PowerVM Standard Edition WPAR Manager 2.1
AIX 7.1 Express Edition AIX 5.2 Workload Partitions for AIX
AIX 7.1 Enterprise Edition WPAR Manager 2.1
An administrator has configured NTP on the HMC using the hostname of a public NTP server and restarts the HMC. When the /var/log/ntp file is checked, the synchronization with the time server has not occurred. What is the most likely cause?
The firewall needs to be opened for xntp.
The "chhmc -c xntp -s start" command needs to be run.
The time server needs to be specified by IP address on an HMC.
NTP has been configured on the private network.
An application requires 40GB of memory, but only 20GB of memory can be allocated to the partition. What Active Memory Expansion factor should be set for the Hypervisor to target

All IBM certification tests presume a certain amount of "on-the-job" experience which is not present in any classroom or Web presentation. These recommended roadmaps will help you gain the skill and product knowledge which is represented in the test objectives. They do not teach the answers to the test questions, and are not intended to do so. These courses may not cover all subject areas in the certification test(s), or may contain more recent information than is present in the certification test. Taking any class does not guarantee that you will achieve certification.
Suggested courses are listed for the US only. Courses are often available in other countries and languages. Please check in your country using the first four characters of the course code.
