Company.com has a two-node HACMP cluster with a single cascading resource group. Node ’A’  is the normal production node, and Node ’B’ is the standby node. One of the first steps in the HACMP test plan is to start the cluster and to verify that al elements for the resource group have been acquired. The administrator who is conducting the HACMP test starts the HACMP daemons on Node ’B’ with the ’smitty clstart" command. The administrator notices that Node ’B’ acquires the elements of the resource group, including a service IP labels,a shared volume group, and an application server that has been started. The expectation was that Node ’B’ would enter the cluster in a standby status, rather than acquiring production resources.  What should the administrator do to correct this problem?()   

  • A、 Change the cluster to a rotating design.
  • B、 Change the Cascading without Fallback flag to true.
  • C、 Change the Inactive Takeover field to false in the cluster configuration.
  • D、 Nothing should be done. This is the default behavior for cascading resource groups,and node ’A’ should have been started first.

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.
