1、a cluster with 10 adapter per node is converted to use IPAT address takeover via IP aliasing.During the conversion,the customer ran out of IP subnets in the allocated range.What feature in the HACMP can help resolve this issue?
A.disk based heartbeats
B.heart beating via aliasing
C.ip aliases for the non-service addresses
D.a single subnet for all non-standby adapters

2、 a custer has decided to implement virtual hosts in their web server.the current estimate is to create six virtual hosts with unique URL's and IP addresses. the solution is going to usethe IP aliasing function in HACMP. how many resouce groups are required to support this configure.
A.1
B.2
C.6
C.7

3、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 enviroment 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?
A.one disk per node,on network
B.two disks per node,one network
C.two disks per node,six networks
D.two disks per node,three networks

第二題想不通為什么用1個RG就可以搞定。
第三題的答案是C，我也是選D

yanbing

第二題很容易理解�。�

一個RG可以有多個svc ip�。�

第三題就不知道了�。�！

我現(xiàn)在覺得第一題倒有可能是D。。

看來237的題目確實有難度。。。主要都是平時碰不到的方式

如果在一個RG上配置了多個service ip，那么如何進行takeover呢

這位仁兄的題是從哪里來的？是你考試的時候記下的嗎？

第一題感覺可以是B吧.

IP aliases used for heartbeat
These IP addresses are allocated from a pool of private, non-routable addresses,
and are used to monitor the communication interfaces without the need to
change their base (boot) IP address.
This is useful in certain cases when it is not desirable to change the base IP
addresses (as they are defined in AIX) of the network adapters on each node,
Note: It is possible to configure one persistent node IP label (address) per
network per node. For example, if you have a node connected to two networks
defined in HACMP, that node can be identified via two persistent IP labels
(addresses), one for each network.
Restriction: It is not possible to configure a persistent node IP label on the SP
Switch, on ATM Classical IP, or on non-IP networks.
Chapter 2. Planning and design 27
and those addresses do not conform to the HACMP requirements (they are in
the same subnet, so the network adapters cannot be monitored).
For this purpose, HACMP provides the usage of heartbeat over IP aliases.
