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 customer has an xSeries x445 server attached to a DS4500 storage server containing two EXP710 disk expansion drawers with 14 disks in each.  The x445 is to be used for a video streaming application.  The customer wants to make the most cost-effective use of the disk capacity while retaining fault tolerance.  Which of the following solutions will satisfy the requirements？（）

• A、Create two RAID-10e arrays， one per disk expansion drawer
• B、Create a single RAID-10 array across the two disk expansion drawers
• C、Create a single RAID-5 array across both disk drawers utilizing all disks
• D、Create four RAID-5 arrays in 6+P format with two arrays to each disk expansion drawer

You are the network administrator for . All network servers run Windows Server 2003. The network includes a file server named TestKing17. TestKing17 contains a single disk for system files and two SCSI hard disks that comprise a 72-GB mirrored volume with 65 GB of read-only data. Users connect to this data by using shortcuts on their desktops. TestKing17 is scheduled for replacement. You have a scheduled maintenance window to complete this task. Before the maintainance window, you build a new server. You need to bring the new server online with current data and re-establish redundancy as quickly as possible. You must also ensure that the desktop shortcuts will continue to functions. What should you do?（）

• A、Name the new server TestKing20. Create a new mirrored volume by using two 72-GB disks. Connect TestKing20 to the network and copy the data from TestKing17. When copying is complete, shut down the old TestKing17.
• B、Name the new server TestKing17. Move both disks from the old TestKing17 to the new TestKing17. Scan the disks for changes.Connect the new TestKing17 to the network.
• C、Name the new server TestKing17. Break the mirror on the old TestKing17. Move one of the disks from the old TestKing17 to the new TestKing17. Scan the disk for changes. Initialize the disk. Select the spare disk and create the mirror. Connect the new TestKing17 to the network.
• D、Name the new server TestKing17. Remove one of the disks in the mirror from the old TestKing17. Move the disk to the new TestKing17. Scan the disk for changes. Import the disk. Shut down the old TestKing17 and connect the new TestKing17 to the network.

During the initial cluster design，a disk heartbeat，Point-to-Point non-IP network is being planned  as part of a three-node cluster implementation. The disk environment will use LVM mirroring for disk redundancy. The volume groups will be created as Enhanced Concurrent Capable.  To facilitate disk heartbeating，how many disks per node and how many networks will be required？（）  

• A、 One disk per node，one network
• B、 Two disks per node，one network
• C、 Two disks per node，six networks
• D、 Two disks per node，three networks

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.

A two-node cluster has both a single TCP/IP heartbeat and a single non-IP serial heartbeat. TheService Level Agreement regarding the speed of cluster fallover has been updated，and Fast Disk Takeover will be implemented to meet the new Service Level Agreement.  Which of the following should be implemented to increase the reliability of Fast Disk Takeover？（）  

• A、 Disk should be mirrored across separate storage enclosures.
