Exam : IBM 000-237
Title : Hacmp for aix 5l


1. During a cluster functionality test, an administrator performs a graceful stop for Node 'B' in a three-node cluster. What is the expected state of the cluster after Node 'B' successfully completes?
A.All cluster resources halt on Node 'B', and one or both surviving nodes will gracefully acquire the resources.
B.All cluster processes halt on Node 'B', the cluster resources remain active, and the remaining nodes take no action.
C.All cluster processes stay active on Node 'B', cluster resources are halted, and the remaining nodes take no action.
D.All cluster resources will stop, cluster processes halt on Node 'B', and the remaining cluster nodes take no action.
Answer: D

2. Due to recent changes in infrastructure, a four-node cluster has been split into two locations, but is still listed as a single site in HACMP. The location split has proceeded smoothly, the only exception being the serial heartbeats. There are constant errors causing the serial network to go up and down. What is the best solution to resolve this issue?
A.Install the dialback failsafe optional filesets.
B.Change the speed parameter in "smitty tty" to be 38400,8,N,1.
C.Install additional rsct filesets required for non null modem connections.
D.Change the parameters in the Network Module to stop RSCT from changing the speed of the line.
Answer: D

3. During an HACMP installation, it is discovered that the customer is using the 802.3 frame type on the Ethernet adapters. How will this affect HACMP?
A.HACMP will support all Ethernet frame types except EtherChannel.
B.HACMP will not complete autodiscovery if an adapter of type 802.3 is discovered.
C.HACMP does not support 802.3 frame types and will ignore any adapters that are that type.
D.HACMP does not support 802.3 frame type but will attempt to add them to HACMP networks during the discovery process.
Answer: D

4. During a customer planning session, the LVM requirements for HACMP are provided. The administrator explains that there are five volume groups in the current production environment because filesystems constantly change due to the nature of the business. Maintenance outages are limited to one Saturday per month. There is some concern about the amount of time that will be required for outages once HACMP is installed. With HACMP, what will be the simplest method of managing LVM changes while minimizing required downtime?
A.Make changes and allow Lazy Update to sync the changes later.
B.Use the Cluster Single Point Of Control to manage LVM changes.
C.Use exportvg on the primary node and importvg on the second node.
D.Set up a local NFS cross-mount, and use the local filesystem until the outage.
Answer: B

5. During a planning session, a customer expresses concern about the behavior of the nodes when HACMP is installed. One 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.
