Company.com has a three-node cluster with six resource groups. There are two resource groups  for each node. A new hardware component will be added to one of the nodes. The customer wants to move the resource groups to other nodes，but not necessarily in the normal fallover order. Also，the resource groups must be moved at night when there is no one in the computer center. What can be done so that the resource group is moved at the most convenient normal fallover order. Also，the resource groups must be moved at night when there is no one in the computer center.  What can be done so that the resource group is moved at the most convenient time for the customer？（）   

• A、 Create a custom resource group with a custom fallback timer to cause the system shutdown at he appropriate time.
• B、 Set the system to stop with "shutdown" command at the appropriate time and allow HACMP to relocate the resources.
• C、 Use a script that calls the cIRGmove command and place it in the cron or a queue to execute at the appropriate time.
• D、 Change the existing resource groups to a custom type and add a timer to perform a "shutdown -h" command at the appropriate time.

While installing the equipment for a new two-node cluster， it is discovered that the disk subsystem  Rack has one connection to the power mains. The explanation given was that the disks are to be mirrored between the two disk drawers in the rack and that a failure in either of the disk drawers would simply result in half of the disk being lost.  What can be done to avoid a single point of failure？（）   

• A、 Customize HACMP to overcome quorum issues.
• B、 Add a second PDU to separate the power connections.
• C、 Use RAID5 when implementing two IO racks in a HACMP environment.
• D、 Add another shared disk to each volume group to avoid quorum issues during fallover.

A system is being booted into maintenance mode due to root password recovery.  After accessing the root volume group and starting a shell without mounting the file systems， what is the next step？（）  

• A、Delete root’s password from the /etc/security/passwd file.
• B、Use the diag recovery tool option to reset root’s password.
• C、Execute the ’passwd’ command and assign a new passwd to root UId
• D、Mount the / and /usr filesystems on alternative mount points to edit the password file.

第7题：

While performing a site survey to document the existing environment before implementing a new HACMP cluster， it was discovered that a port filtering firewall was being used to protect the production system. The plan is to continue using the firewall and add a second firewall to avoid a single point of failure. Each node in the two-node cluster will have all of its network adapters connected to the firewalls， and all connections to the nodes will pass through these firewalls.  What must be considered about HACMP in a firewall environment？（）  

• A、 Firewalls are not supported in a HACMP environment.
• B、 HACMP uses only TCP/IP so firewalls are not relevant.
• C、 Specific ports must be open for HACMP communications.
• D、 Dynamic routing must be used to properly route packets in a firewall-protected environment.
