A. HACMP cannot span sites； the environment must be contained in a single site.
B. HACMP/XD：HAGeo has unlimited distance mirroring that may be appropriate for this environment.
C. HACMP cannot be split into two sites that exceed the limitation s of the storage cable length.
D. HACMP/XD：PPRC that is included with the base HACMP distribution will enable site-to-site communications in HACMP.

A node in a three-node cluster was started， ad it acquired the following three cascading resourcegroups： ’rg1’， ’rg12’， and ’rg3’. The cluster design is to have ’rg1’ normally Node ’A’， ’rg2’ normally on Node ’B’， and rg3’ normally on Node ’C’. How can the administrator reposition the resource groups and correct the problem？（）
A. Change the cluster resource group definitions from cascading to rotating，synchronize the cluster，and restart HACMP
B. Edit the /urs/es/sbin/utilities/clhosts file to reflect he desired node-to-resource group relationships and restart HACMP
C. Use the clRGMove utility move rg2 o Node ’B’ and rg3 to Node ’C’，then start the cluster manager on Nodes ’B’ and ’C’ with the clstart utility
D. Disable Inactive Node Takeover，check the node priority list in the resource groups definitions，synchronize the cluster，and start HACMP on Nodes ’B’ and ’C’

During Company.com 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 methods of managing LVM changes while minimizing required downtime.（）
A. Make changes and allows 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 improtvg on the second node.
D. Set up a local NFS cross-mount， and use the local filesystem until the outage.
