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.

第2题：

Company.com has a non-IBM disk storage unit connected by two Fibre channel connections. The  Nodes have multiple connections to the storage device that allow load balancing. A failure with one Fibre adapter or connection will not be noticed by the application， but it needs to be addressed.  How can HACMP help make this environment more robust？（）  

• A、 Customize disk heartbeat methods to detect disk adapter failures.
• B、 Customize an error notification method that monitors for volume group quorum loss.
• C、 Customize an error notification facility to act on the event when reported to the error log.
• D、 Customize a HACMP event script to monitor the disk connections and cause a fallover if there is a failure.

Company.com has decided to implement the "Fast Disk Takeover" and "Disk Heart Beat"  features of HACMP. What IBM distribution media will be required for a default installation？（）  

• A、 AIX media only
• B、 HACMP media only
• C、 AIX and HACMP media
• D、 HACMP and Concurent Resource Manager media

第5题：

An administrator has mirrored the root volume group to a second disk， but ’bootlist’ is failing to correctly add the second disk.  What is the likely cause of the problem？（）  

• A、The administrator has failed to run ’bosboot -ad <2nd disk>’ prior to the bootlist command.
• B、The administrator has failed to run ’bootinfo -B <2nd disk>’ prior to the bootlist command.
• C、The administrator has failed to run ’mirrorvg -m rootvg <2nd disk>’ prior to the bootlist command.
• D、The administrator has failed to run ’bosboot -ad /dev/ipldevice <2nd disk>’ prior to the bootlist command.

第6题：

Company.com has non-IBM fibre attached storage. The storage is connected to a node in the  cluster that has multiple adapters and virtual paths. There is a concern about detecting the loss of one of the fibre adapters since there is no indication to the administrator that one has failed.  What feature of HACMP can be sued to assist with this issue？（）  

• A、 Disk heartbeat
• B、 Error notification
• C、 Event notification
• D、 Application monitor

第7题：

After an HACMP migration， which included a large number of shared disks，cluster testing is   performed. During testing， it becomes apparent that Fast Disk Takeover is not working properly.  Which of the following is the most likely cause of the problem？（）  

• A、 The shared volume groups have not been converted to Big VGs.
• B、 The ’t factor" needs to be set on the volume group using chvg -t 2 vgname.
• C、 The shared volume groups have not been converted to enhanced concurrent mode.
• D、 The shared volume groups need to be varied on using the passive varyon option on all nodes.

第9题：

A two-node cluster has both a single TCP/IP heartbeat and a single non-IP serial heartbeat. TheService Level Agreement regarding the speed of cluster fallover has been updated，and Fast Disk Takeover will be implemented to meet the new Service Level Agreement.  Which of the following should be implemented to increase the reliability of Fast Disk Takeover？（）  

• A、 Disk should be mirrored across separate storage enclosures.
• B、 Disk heartbeats should be added over multiple disk adapters.
• C、 Disk major and minor numbers should be set as unique across nodes.
• D、 Disk adapter queue_depth should be increased from the default values.

第10题：

Companycom has a Linux LPAR on a p5 570 server. The 3rd party storage subsystem devices are not supported by Linux. How would access be provided to the storage subsystem devices for this Linux LPAR?（）

• A、Daisy chain the unsupported 3rd party storage subsystem devices with the local SCSI disk drive 
• B、Assuming the 3rd party storage subsystem has AIX support, enable access through a Virtual IO Server 
• C、Assuming the 3rd party storage subsystem has AIX support, implement the Linux partition within an AIX partition 
• D、3rd party storage is not an option for p5 570 servers and therefore only IBM disk subsystems can be considered as a solution
