1.
A customer has installed HACMP and is configuring a three-node cluster. One of the applications uses the AIX hostname as a key for authorization to execute on the specific computer. The application vendor was contacted and consented to having multiple copies of the application but required that only one application be active at any one point in time. How can the AIX host name dependency be managed in an HACMP environment?
2.
A customer 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 create a cluster. What considerations must be addressed during the planning session?
3.
A customer with an EtherChannel implementation is considering an HACMP solution. What considerations must be addressed in planning this configuration?
4.
A customer is adding HACMP to an existing pair of nodes. One node is using EtherChannel with only one adapter. The other node is using regular Ethernet connection to the switch. The customer is going to increase the number of network interfaces to two for each node. What other considerations need to be addressed in a HACMP environment?
5.
The administration staff of a large computer complex is resisting the installation of HACMP. There are concerns about the difficulty of managing and administering an HACMP cluster without an "administration only" network. Adding adapters to create an administration network is not possible due to limitations on the number of open IO slots in the servers. What can be done to address this issue?
6.
A customer 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?
7.
A customer is planning for an HACMP cluster and wants to know more about the network requirements. The plan is to use IPAT via IP aliasing and heartbeating via IP aliasing to preserve the corporate IP addresses. Currently the customer uses a separate VLAN for each individual subnet. Which statement best describes how HACMP co-exists with VLAN's in this configuration?
8.
During the initial cluster design, a disk heartbeat, Point-to-Point non-IP network is being planned as part of a three-node cluster implementation. The disk environment will use LVM mirroring for disk redundancy. The volume groups will be created as Enhanced Concurrent Capable. To facilitate disk heartbeating, how many disks per node and how many networks will be required?
9.
Continuous availability is required for an application in a two-node cluster. There is one rotating resource group in the cluster, and the nodes are identical machines. Client telnet connections to the application cannot be broken because it takes 20 to 30 minutes to recycle the client workstations and transactions will be lost. What configuration best provides continuous connectivity to the application?
10.
During a customer 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?
