In order to successfully install HACMP， which non-default AIX lpp is a requirement？（）  

单项选择题A cluster administrator is concerned about using the forced varyon resource group function. Although the function provides increased data availability if it is enabled for a cluster resource group， management is concerned about data integrity.  If a varyonvg command fails， an HACMP forced varyon will only occur if which of the following is true？（）

A. A loss of quorum has occurred on one of the disks in the failed volume group.
B. Selective fallover caused by an application moves a resource group to a takeover node.
C. A check is made to ensure at least one complete copy of all data is available in the volume group.
D. The MISSING_PV=TRUE environment variable has been set causing the volume group to be forced online.

单项选择题Using the C-SPOC utilities， an administrator has created a new volume group and filesytems. Theadministrator performs an Isvg -I command on the volume group and notices that the log logical volume created in C-SPOC is closed syncd and loglv01 has been created and is in use.  What step was required in order for the logfile created by C-SPOC to be used.（）

A. Perform the C-SPOC logform utility option prior to creating any filesystems.
B. Manually perform a logform outside of C-SPOC prior to creating any filesystems.
C. Run a logredo command and select log logical volume created in C-SPOC as the preferred jfslog.
D. Use C-SPOC to delete and recreate the log logical volume，set the perform logform option to true.

A. One adapter per node
B. Two adapters per node
C. Four adapters per node
D. No additional adapters per node

A. Adds to all nodes with the cluster running.
B. Adds to all nodes with the cluster stopped.
C. Adds with the cluster running，uses "Lazy Update" to perform the logical volume synchronization.
D. Adds to all nodes with the cluster running but requires the volume groups to be exported andimported after.

单项选择题A two-node cluster is attached via SAN to shared disk. The customer has requested that one of  the nodes be moved to another room 300 feet away. However， this distance exceeds the length specified by the RS232 specifications.  What solution would resolve the RS232 specification issue with the fewest additional components？（）

A. Target mode fiber channel can be used with a SAN solution.
B. The heartbeat could be established by using a disk heartbeat.
C. An RS232 line driver can be used to extend the existing serial connection.
D. The NIM for the serial connection can be altered to compensate for the additional delay caused by the increased distance.
