Braindumps of 000-237
pSeries HACMP for AIX 5L

Exam Questions, Answers, Braindumps (000-237)

I have questions for you but I have only one suggestion for you to just go for www.examcheats.net study material.
Try my questions too. You will get the success.

QUESTION 1
During Abc .com planning session, the network administrator discusses the requirements of having a persistent MAC address associated with the IP Service address. How can this be accomplished using HACMP?
A. Enable routed to handle dynamic route creation.
B. Use IPAT via IP aliasing and define the required MAC address.
C. Add the Service IP Label to the /etc/cluster/ping_client_list.
D. Use IPAT via IP replacement and define the required MAC address.
Answer: D
QUESTION 2
During a planning session, it is determined that both nodes in a mutual takeover cluster will provide NFS mounts to a variety of Unix hosts. What is the first consideration that must b4e taken into account when using NFS with HACMP?
A. AIX Connections will need to be installed to provide the NFS shares.
B. Mutual takeover cluster cannot provide NFS services from both nodes.
C. The major number for the volume groups needs to be the same on both nodes.
D. The no option rfc 1323 must be set to 1 and the number of biods need to be adjusted to provide reasonable response times.
Answer: C
QUESTION 3
A database administrator wants a unique IP address for each of three instances of a database. Normally, all instances run on a large production node, but they may fallover to different standby nodes according to the dynamic node priority configuration. What is the best way to obtain unique addresses for each of the three database instances?
A. There is no way since this cannot be configured with HACMP.
B. Use IP Replacement address takeover and define all service addresses on the same NIC.
C. Use IP Aliasing for address takeover and define each alias in a separate resource group.
D. Use EtherChannel to map the three alias IP addresses to the common service address defined to HACMP.
Answer: C
QUESTION 4
Abc .com has several network adapters configured as backup paths using the Virtual IP addressing and dynamic routing of AIX. A second node needs to be added to the environment to crate a cluster. What considerations must be addressed during the planning session?
A. HACMP supports most types of networks, including Virtual IP Addressing by AIX.
B. If HACMP IP aliasing is used, the devices may be the Virtual IP type used by AIX.
C. Using the AIX Virtual IP Addressing scheme HACMP can provide near fault tolerant availability of the network.
D. The AIX Virtual Addressing mechanism is not supported by HACMP, but a similar configuration can be created in HACMP.
Answer: D
QUESTION 5
Abc .com has a new computer room that will be used to house a new HACMP cluster. Once of the outstanding features of the new computer room was the new large air conditioner. This unit has enough excess capacity for more than double the planned amount of equipment. Another feature of this computer room was the dual electric supplies to the room housed in two separate power panels. How would this impact the overall availability of the environment?
A. Dual power feeds will make the installation difficult to manage and less high available.
B. The single air conditioner is a single point of failure and the customer should be made aware of the issue.
C. The single air conditioner is a single point of failure and HACMP should be customized to compensate for the issue.
D. A single power feed should be used to avoid ground loops in the computer room causing premature failure of the systems.
Answer: B
QUESTION 6
Abc .com has an application that requires a serial connection for Electronic Data Interchange. What must be done to integrator the serial connection into an HACMP cluster?
A. Use an RS3232/422 serial Y cable.
B. Alter the device settings to 9600 8/n/1 xon/xoff.
C. Use a network based terminal server for the serial connection.
D. Nothing because HACMP does not support native serial connection fallovers.
Answer: C
QUESTION 7
During a planning session, Abc .com expresses concern about the behavior of the nodes when HACMP is installed. Once department is reliant on an older piece of equipment that is critical to operations and must communicate to the database server. Previous network changes indicated that this piece of equipment does not support gratuitous ARP. How can HACMP best incorporate this restriction into the cluster design?
A. The administrator must use Hardware Address Take over with HACMP.
B. The clsmuxpd process and the contents of the /etc/cluster/ping_client_list can address the issue.
C. HACMP does not have any facility to be compatible with older devices that have limited capabilities.
D. HACMP can use either hardware address take over, or clinfo can update the arp cache of the clients when an adapter event occurs.
Answer: D
QUESTION 8
An enterprise has three nodes: -Node 'A' is a production database, -Node 'B' is a production application server, and -Node 'C' is a test and development node. Node 'C' is used by six programmers to develop and the production application as business critical and would like to make it highly available with HACMP. Application development and testing is not business critical. Which of the following describes the best solution?
A. There is not an adequate solution because HACMP should not be configured in this environment without a dedicated standby node.
B. Nodes 'A' and 'B' should be configured in a cluster with mutual fallover of two cascading resource groups to provide both nodes will deliver acceptable response time with both resource groups.
C. Nodes 'A' and 'C' should be configured in one cluster, and Nodes 'B' and 'C' in another cluster to prevent both the database and application server from falling over to Node 'C' at the same time.
D. Nodes 'A', 'B', and 'C' should be configured in a cluster with Node 'C' the hot standby for both the database and application server resource groups. Workload Manager (WLM) must be configured on database and application developers from over utilizing the CPU resources.
Answer: B
QUESTION 9
Abc .com wishes to use IPAT via IP replacement in a two-node mutual cluster. Each node has two Ethernet 10/100/1000 adapters. Throughout the planning session, the customer has asked questions about subnet and VLAN requirements for the intended network topology. Which of the following best describes the network requirements?
A. The service IP addresses must be on a separate subnet and VLAN.
B. The non-service and service IP addresses must be on the same subnet and on the same VLAN.
C. All interfaces on a node must be in different subnets. All subnets must be on the same VLAN.
D. One non-service and one service IP address must be on the same logical subnet. All interfaces must be on the same VLAN.
Answer: D.
