单项选择题Company.com recently updated the programs used in an HACMP pre-event. The procedure Involved coping the new code over the old code in the appropriate directory on one of the nodes as indicated by the HACMP event entry. The cluster was synchronized. During a fallover test， the backup system did not behave as expected.  What is the most likely problem？（）

A. The new pre-event program was node locked to a hostname
B. The new pre-event program was not made executable on al nodes.
C. The new pre-event program was not compatible with the backup machine.
D. The new pre-event program was not propagated to all the nodes in the cluster.

单项选择题Company.com has an application that has a hard-coded hostname in the startup routines. The application is being made highly available using HACMP. During testing， the application does not start on the standby node because the hostname was not what the application expected.  What can be done to fix this problem？（）

A. Manage the hostname in the application server start ands top scripts
B. Nothing， because this application cannot be controlled by HACMP and should be started  with   /etc/inittab
C. Change the hard-coded hostname in the application startup routines to use the uname rather than the hostname
D. Override the default ha_hostname in the cluster configuration to reflect the shared hostname rather than the default ha_hostname

单项选择题Company.com 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？（）

A. Al interfaces used for HACMP heartbeats must be identical. Differences in the interfaces will cause heartbeat failure.
B. The network interfaces should all be configured with the same frame type. The use of regular Ethernet frames is mandatory.
C. Network interfaces for HACMP must be all the same，Ethernet or 802.3. It does not matter which，as long as they are all the same.
D. HACMP can use any network interface supported by AIX. The options on the various interfaces are masked by the Ethernet switch and do not affect HACMP.
