第1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?()
第2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?()
第3题:
A customer needs maximum performance with fault-tolerance from their disk subsystem. Which RAID level meets this requirement?()
第4题:
A customer has a requirement for a single AIX LPAR to be highly available. The customer only has enough funding to purchase a single system. Which would be the most critical option to mitigate AIX availability?()
第5题:
Company.com is migrating from a third party managed disk subsystem to an IBM TotalStorage Enterprise Storage Server. Connection of the new storage server is complete, and it has been tested on all of the nodes in the three node HACMP cluster. How does the customer migrate to the new storage server with minimum down time?()
第6题:
Run cfgmgr
odmdelete CuAt
exportvg rootvg
Deallocate LPs from failed disk
第7题:
A
B
C
D
第8题:
One disk per node,one network
Two disks per node,one network
Two disks per node,six networks
Two disks per node,three networks
第9题:
Use the clinfo command to monitor the disk heartbeat
Use the mail command to check for messages form HACMP
Use the dhbread command to verify the disk heartbeat link
Use the clstat command to verify the appropriate network connections are available
第10题:
Target mode fiber channel can be used with a SAN solution.
The heartbeat could be established by using a disk heartbeat.
An RS232 line driver can be used to extend the existing serial connection.
The NIM for the serial connection can be altered to compensate for the additional delay caused by the increased distance.
第11题:
Disk should be mirrored across separate storage enclosures.
Disk heartbeats should be added over multiple disk adapters.
Disk major and minor numbers should be set as unique across nodes.
Disk adapter queue_depth should be increased from the default values.
第12题:
Only the heartbeat IP network can exist in a VPN style network.
HACMp must have separate VPN’s for all ’non-service’ and ’service’ adapter networks.
If a VPN is used for IP traffic the heartbeating must be done over disk connections.
HACMP can exist in a VPN network environment,but special considerations must be addressed.
第13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?()
第14题:
During the initial cluster design,a disk heartbeat,Point-to-Point non-IP network is being planned as part of a three-node cluster implementation. The disk environment will use LVM mirroring for disk redundancy. The volume groups will be created as Enhanced Concurrent Capable. To facilitate disk heartbeating,how many disks per node and how many networks will be required?()
第15题:
A client has the need to reboot one of their Virtual IO Servers. What command(s) would be run to list the clients that are dependant on Virtual IO Server disk and network resources?()
第16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?()
第17题:
lsmap -all -net
lsclient -disk -net
lsdev -virtual -client
lsmap -all; lsmap -net
第18题:
RAID-0
RAID-1
RAID-5
RAID-10
第19题:
The Disk hearbeat facility is initialized when creating enhanced concurrent mode volume groups through HACMP.
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.
The ’Chdev -v-C
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20题:
Dual power supplies.
Twice the amount of disk.
Two dual-port LHEA adapters.
Two dual-port fibre channel adapters.
第21题:
Build each server from the OS manufacturer’s build disk.
Use an imaging system to manually deploy the build to the servers.
Build each server with the manufacturer’s build disk.
Give the company build disk to the server manufacturer.
第22题:
Compress the volume.
Defragment the volume.
Convert the disk to a dynamic disk.
Enable Shadow Copies on the volume.
第23题:
More disk should be added to the disk heartbeat network,allowing more paths for heartbeats.
An RS232 network is required to supply a more robust non-IP network when disk heartbeating is implemented.
The network tunable parameters should be changed to allow more missed heartbeats since the disks may be heavily used.
An error notification method is required to determine the action to take in response to a failure of the disk heartbeat.
