IBM Assessment: Power Systems Virtualization Technical Support for AIX and Linux -v2 認定 A4040-109 試験問題:

1. A system administrator needs to configure a redundant network environment for several AIX and Linux clients on a Power Systems server. Which highly available Virtual I/O server network solution should be used to meet this requirement?

A) VLAN tagging
B) Link Aggregation
C) Shared Ethernet Adapter Failover
D) Network Interface Backup

2. A number of POWER7 servers have been ordered to replace an existing infrastructure of POWER4 machines. All existing LPARs will be manually recreated on the new machines, preserving the installed operating systems.
An administrator is planning to attach the POWER7 machines to the subnet, allowing the LPARs to keep their hostname and IP addresses. The NIM server that will be used to restore the LPARs on the new machines allows its clients it initiate NIM client commands.
What needs to be considered to preserve the ability to restore an existing LPAR on the new infrastructure?

A) LPAR profiles need to be consistent between old and new infrastructure.
B) The POWER7 machines will be managed by a different HMC.
C) NIM client CPU ID validation should be disabled before installation on the new hardware.
D) Prior to migrating to POWER7, the AIX levels of the existing LPARs may need to be updated.

3. A client is planning to purchase a Power 770 with 2 enclosures, and needs to have redundancy for multiple LPARs. Which of these solutions provides the most redundancy for the LPARs at least cost?

A) Assign an IVE logical port from each enclosure to each LPAR. Assign an HBA from each enclosure to each LPAR.
B) Create two VIO servers assigning IVE and HBA adapters from different enclosures.
Configure SEA failover on the VIO servers and assign a virtual Ethernet adapter to the
LPARs. Assign SAN mapped virtual SCSI disks from each VIO server and use MPIO on
the LPARS.
C) Create two VIO servers assigning IVE and HBA adapters from different enclosures.
Assign a virtual Ethernet adapter from each VIO server to Setup NIB on the LPARs. Assign SAN mapped virtual SCSI disks from each VIO server and use MPIO on the LPARS.
D) Create a VIO server with two IVE adapters from different enclosures.
Configure EtherChannel on the VIO server and assign a virtual Ethernet adapter to the
LPARs. Assign an HBA from each enclosure to each LPAR.

4. A customer has four LPARs: VIO1, VIO2, LPAR1 and LPAR2 VIO Servers (VIOS) are configured with SEA adapter failover and 802.1Q is enabled on the LPARs.
During scheduled maintenance, VIO1 is brought down and the SEA failover happens automatically.
However, network traffic is not leaving the VIO for LPAR1.
The SEA interfaces are setup as follows:
VIO1 - SEA PVIDs 55,60,65,70 VIO2 - SEA PVIDs 45,60,65,75
The LPARs have their virtual network devices setup as follows:
LPAR1 - Adapter ID 55 - VLAN ID 75 LPAR2 - Adapter ID 60 - VLAN ID 45
What is the reason for the networking problem?

A) The LPARs have the wrong adapter IDs configured.
B) VIO2 has the wrong VLAN IDs configured.
C) LPAR1 has the wrong VLAN ID configured.
D) The LPARs and the VIO servers are on different subnets.

5. A systems service processor is being connected to a redundant HMC. Which of the following is required to support DHCP server on dual HMCs?

A) The two HMCs must be on different subnets.
B) The first HMC must be set as primary DHCP range.
C) Both HMCs must be running RMC on a shared private network.
D) The redundant HMC must have the 'Redundant DHCP Range' check box selected on ethernet ent0 configuration.
