單項選擇題
During an internal IT organization planning session， it is decided that a new cluster node would Enhance the performance of a distributed corporate application. Planning details have been assigned to the administrator. System outages are limited to one weekend per month； therefore， availability will be a key issue in the planning process. How much cluster downtime will need to be allocated for adding a new node？（）
A. None，everything can be done with the cluster active.
B. Minimal downtime will be required to import the volume groups.
C. Several hours are required for testing before final synchronization.
D. Minimal downtime will be required to connect and test the serial network.
單項選擇題
An administrator mistakenly shutdown production after a fallover because the service IP address Was shifted from the normal production node to the standby node. What can be done to avoid this type of mistake in the future？（）
A. Include the service IP address in the administrator’s PS1 prompt
B. Alias the service IP address to the hostname in the /etc/host file
C. Define a persistent IP address with HACMP and make it a practice to use the persistent address for administration work
D. Add a DNS entry to map the standby node name to the service IP address so telnet connections will be to the correct node
單項選擇題
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.
單項選擇題
A node in a three-node cluster was started， ad it acquired the following three cascading resourcegroups： ’rg1’， ’rg12’， and ’rg3’. The cluster design is to have ’rg1’ normally Node ’A’， ’rg2’ normally on Node ’B’， and rg3’ normally on Node ’C’. How can the administrator reposition the resource groups and correct the problem？（）
A. Change the cluster resource group definitions from cascading to rotating，synchronize the cluster，and restart HACMP
B. Edit the /urs/es/sbin/utilities/clhosts file to reflect he desired node-to-resource group relationships and restart HACMP
C. Use the clRGMove utility move rg2 o Node ’B’ and rg3 to Node ’C’，then start the cluster manager on Nodes ’B’ and ’C’ with the clstart utility
D. Disable Inactive Node Takeover，check the node priority list in the resource groups definitions，synchronize the cluster，and start HACMP on Nodes ’B’ and ’C’
單項選擇題
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.
單項選擇題
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’
單項選擇題
Company.com performs cluster verification every Sunday night with a corn job. The systems administrator reviews the /var/hacmp/clverify/clverify.log on Monday morning and notice that cluster verification posted a message about inconsistent filesystem names in one of the shared volume groups. What should the administrator do？（）
A. Cause a fallover to occur on the resource group.
B. Export the volume groups and re-import them on all nodes.
C. Run an importvg -L command on all the nodes in the cluster.
D. Investiage recent changes to the shared volume group and use C-SPOC to correct inconsistencies.
單項選擇題
A cluster administrator is trying to configure tmssa for the non-IP network. Having installed the devices.ssa.tm.rte fileset， what is the next step that must be performed to create the target mode devices？（）
A. Reboot each cluster node.
B. Change the ssa node number to a non-zero value.
C. Change the SSAR device state from defined to available.
D. Run the cfgmgr process on each node to create the target mode devices.
單項選擇題
While an electrician was adding additional circuits for the Data Center， the system running the Database inadvertently powered down. The fallover of the service IP labels and volume groups to the hot standby node completed as expected； however， the database did not start. The database log file indicated that the database was already started. What is the most likely cause of this problem？（）
A. The shared logical volumes and filesystems did not have database permissions.
B. There was a test instance running on the standby system that must be shutdown.
C. The tablespaces had an indicator indicating that the database had not shutdown properly.
D. The startup script for the highly available instance did not first perform cleanup operations.
單項選擇題
Company.com has decided to implement VPN for all network traffic. How might this might affect HACMP？（）
A. Only the heartbeat IP network can exist in a VPN style network.
B. HACMp must have separate VPN’s for all ’non-service’ and ’service’ adapter networks.
C. If a VPN is used for IP traffic the heartbeating must be done over disk connections.
D. HACMP can exist in a VPN network environment，but special considerations must be addressed.
