单选题
During an HACMP migration,two nodes of a four-node cluster have been migrated. The existing hardware of the remaining two nodes do not meet the pre-requisites of the HACMP level that is being installed.  Which of the following is the best method for resolving this issue?()
A

B

 Restore the two nodes that have been migrated with a cluster snapshot.

C

 Restore the two nodes that have not been migrated with a cluster snapshot.

D

第1题:

During a cluster functionality test, and administrator performs a graceful stop for Node ’B’ in a three-node cluster. What is the expected state of the cluster after Node ’B’successfully completes?()  

  • A、 All cluster resources halt on Node ’B’,and one or both surviving nodes will gracefully acquire the resources.
  • B、 All cluster processes halt on Node ’B’,the cluster resources remain active,and the remaining  nodes take no action.
  • C、 All cluster processes stay active on Node ’B’,cluster resources are halted,and the remaining nodes take no action.

正确答案:D

第2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.

  • A、 Perform a graceful takeover one node at a time and apply the updates.
  • B、 Perform the updates on all nodes simultaneously using C-SPOC utilities.
  • C、 Perform the updates on node at a time with the cluster software active.
  • D、 Perform a graceful stop of all cluster nodes and apply updates to all nodes.

第4题:

A cluster administrator is performing fallover testing during a scheduled system outage. Node ’A’  Was forced down and eventually rebooted. When Node ’A’ reintegrates into the cluster, the resource group state is offline. No errors are found in reviewing the hacmp.out file.  What could have been done to ensure the resource group was acquired when cluster processing was restarted on Node ’A’?()

  • A、 Nothing,HACMP does not require them automatically.
  • B、 Force the remaining nodes down,then reintegrate them all.
  • C、 Select reacquire resources after forced down on start menu.
