第1题：

A two-node cluster is attached via SAN to shared disk. The customer has requested that one of  the nodes be moved to another room 300 feet away. However， this distance exceeds the length specified by the RS232 specifications.  What solution would resolve the RS232 specification issue with the fewest additional components？（）

• D、 The NIM for the serial connection can be altered to compensate for the additional delay caused by the increased distance.

第2题：

During normal cluster processing in a five-node cluster，one of the nodes unexpectedly crashes. A review of the system dump indicates that a DMS timeout has occurred. The cluster is configured to use disk heartbeats as a Point-to-Point network.  What should be done to address the problem with this configuration？（）  

• A、 More disk should be added to the disk heartbeat network，allowing more paths for heartbeats.
• B、 An RS232 network is required to supply a more robust non-IP network when disk heartbeating is implemented.
• C、 The network tunable parameters should be changed to allow more missed heartbeats since the disks may be heavily used.
• D、 An error notification method is required to determine the action to take in response to a failure of the disk heartbeat.

第3题：

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4题：

A customer needs maximum performance with fault-tolerance from their disk subsystem. Which RAID level meets this requirement？（）

• A、RAID-0
• B、RAID-1
• C、RAID-5
• D、RAID-10

第5题：

An operator just completed a repair to a disk subsystem that contains a disk heartbeat. Before returning the system back into production mode， there is a requirement to verify the disk heartbeat is functioning.  How should the operator determine if the disk heartbeat network functioning？（）   

• A、 Use the clinfo command to monitor the disk heartbeat
• B、 Use the mail command to check for messages form HACMP
• C、 Use the dhbread command to verify the disk heartbeat link
• D、 Use the clstat command to verify the appropriate network connections are available

A customer has a requirement to build a 4 node cluster. Disk heartbeating will be used as the non-IP network.What is the maximum number of disk heartbeat point-to-point links one would need to implement in order toachieve the highest level of availability？（）

• A、4
• B、6
• C、8
• D、12

第7题：

While adding the forced varyon volume group option， it is decided to create a disk heartbeat  Network over the disk paths. Which HACMP function is used to create disk heartbeat devices？（）

• A、 The Disk hearbeat facility is initialized when creating enhanced concurrent mode volume groups through HACMP.
• B、 HACMP does not create the disk heartbeat area directly； RSCT facility creates the area used for the disk heartbeat when the device is started by Group Services.
• C、 The ’Chdev -v-C " command creates an enhanced Volume Group from an ordinarilyVolume Group. This creates the heartbeat region on the vfirst disk in the chain.
• D、 The disk heartbeat area on the disk is created and initialized when the device is created inHACMP "Extended Configuration -> Extended Topology -> Disk heartbeat facility" smit path.
