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.

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.

第4题：

The Cluster Administrator wants to use disk heartbeats as a non-IP network. What Volume Group consideration must be accounted for prior to configuring disk heartbeats？（）  

• A、 The Volume Group major number must be the same on all nodes.
• B、 The Shared Volume Group must be created with the Big VG format.
• C、 The Volume Group must be created as Enhanced Concurrent Capable.
• D、 The "t factor" must be doubled to create the reserved area for disk hearbeats.

第5题：

What must an administrator do to create two new volume groups on a system with only one spare disk?（）

• A、Run the 'mkvg -M' command to create multiple volume groups on a single disk
• B、Add a new disk to the system or release a disk from the one of the existing volume groups
• C、Run the 'mkvg' command to create multiple volume groups on a single disk providing the disk does not have a PVID
• D、Run the 'mkvg' command to create multiple volume groups on a single disk providing the volume groups have the same PP size

第6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7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

第9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.

第10题：

Error log analysis indicates that a disk is starting to fail and will need to be replaced. The failing disk contains multiple logical volumes which span multiple disks. A free disk has been added to the failing disk’s volume group.Which of the following is the most efficient method to move the data from the failing disk to the new disk？（）

• A、Back up the data， remove the failing disk from the volume group， then restore the data to the new disk.
• B、Use the migratepv command to move data from one disk to another and then remove the failing disk from the volume group.
• C、Use the mirrorvg command to mirror the data to the new disk， break the mirror and then remove the failing disk from the volume group.
• D、Create a new filesystem on the new disk and use the mv command to move the data to the new filesystem， and then remove the failing disk from the volume group.
