单选题 During a planning session, it is determined that a three node cluster (Node ’A’, Node ’B’, and Node ’C’) will meet the customer’s application needs. Node ’B’ will be a hot-standby fallover node for both Node ’A’ and Node ’C’ resource groups.  A serial network for this cluster will require which connections?()  

A

 A single serial network between Node ’A’ and Node ’B’ and Node ’C’

B

 A point-to-point link between Node ’A’ and Node ’C’,and Node ’B’ and Node ’C’

C

 A serial network between Node ’A’ and Node ’C’,and a serial network between Node ’B’ and Node ’C’

D

 A point-to-point link between Node ’A’ and Node ’B’ Node ’B’ and Node ’C’ and Node ’A’ ad Node ’C’

单选题 Company.com has a six-node concurrent resource group with an application that is accessed by  a web connection to the cluster nodes. How is the workload moved to another cluster node during a node failure?()  

A

 The concurrent application must control the web interface through application monitoring.

B

 A second resource group will be required to move the web application and IP label to a new node during a node failure.

C

 The concurrent resource group can support multiple IP labels through IP aliasing so all IP labels are defined in the concurrent resource group.

D

 The dynamic node priority facility in HACMP will relocate the web application and the IP label,if it is correctly defined in the application start and stop script.

单选题 Company.com wishes to use IPAT via IP replacement in a two-node mutual cluster. Each node  has two Ethernet 10/100/1000 adapters. Throughout the planning session,the customer has asked questions about subnet and VLAN requirements for the intended network topology.  Which of the following best describes the network requirements?()  

A

 The service IP addresses must be on a separate subnet and VLAN.

B

 The non-service and service IP addresses must be on the same subnet and on the same VLAN.

C

 All interfaces on a node must be in different subnets. All subnets must be on the same VLAN. 

D

 One non-service and one service IP address must be on the same logical subnet. All interfaces must be on the same VLAN.

单选题 What affect will a shutdown -Fr command have on the resource groups on a cluster node?()

A

 They will be placed in an error state.

B

 They will be released an not acquired by another node.

C

 They will migrate to the next node in the priority list.

D

 They will migrate to the next node and be reacquired by the first node on system restart.

单选题 During the process of fallover testing, a client/server database needs to be tested. On the AIX Server, start/stop/cleanup scripts and server application functionality have been tested.  Before moving onto the next step of fallover testing,what action must be completed?()

A

 Run who -a and validate that client connections are restored.

B

 Verify that the client side application is functioning properly.

C

 Check hacmp.out log file to validate that the application server started.

D

 Verify that the application will successfully stop and restart on the fallover node.

单选题 During Company.com planning session, the network administrator discusses the requirements of having a persistent MAC address associated with the IP Service address.  How can this be accomplished using HACMP?()  

A

 Enable routed to handle dynamic route creation.

B

 Use IPAT via IP aliasing and define the required MAC address.

C

 Add the Service IP Label to the /etc/cluster/ping_client_list.

D

 Use IPAT via IP replacement and define the required MAC address.
