Company.com has a new computer room that will be used to house a new HACMP cluster. Onceof the outstanding features of the new computer room was the new large air conditioner. This unit has enough excess capacity for more than double the planned amount of equipment. Another feature of this computer room was the dual electric supplies to the room housed in two separate power panels. How would this impact the overall availability of the environment？（）A、 Dual power feeds will make the installation difficult to manage and less high available.B、 The single air conditioner is a single point of failure and the customer should be made aware of the issue.C、 The single air conditioner is a single point of failure and HACMP should be customized to compensate for the issue.D、 A single power feed should be used to avoid ground loops in the computer room causing premature failure of the systems.
A cluster administrator has been asked to install HACMP on two nodes with the following hardware： -two CPUs， - 1GB RAM， - one 1 36GB drive， -two 10/100/1000 Ethernet adapters， and -GB Fibre Channel adapters dual attached to SAN storage. In order to eliminate single points of failure，the administrator should first add which of the following：（） A、 an additional 1GB RAM to each node.B、 Another bootable mirrored disk drive.C、 A 10/100/1000 GB Ethernet adapter to be attached to a redundant switch.D、 Nothing，because this is a viable cluster solution with no single points of failure.
