A customeris using thepolicy-managed database by name RACDB on a 4-node cluster. The server namesinthe Clusterare:dasher, vixen, comet, and dancer
There are two server pools defined, frontoffice and backoffice The attributes are as followsServerpoolmportance MinMax
Frontoffice1022 Backoffice512
There are two uniform services being created, crmsrv and hrsrv.
crmsrv is being assigned toserverpoolfrontoffice and hrsrv is assigned to backoffice.
Currently, allfour nodes are up and running. The database and its services are running as follows:
The serverpoolfrontoffice , which is running thecrmsrv service is being run on the dasher and vixen hosts
Theserverpoolbackoffice, whichis runninghrsvc service is being run on comet and dancer hosts.
What happens when the dasher node fails?

A. Because the crmsrv serviceis defined asuniform servicethe cluster ensures at least one node is up and running, which is the current case. So, there will be no service relocation thatwillhappen.

B. One of the nodes is moved from the backofficeserverpool to the fronofficeserverpool . This is moved with the consideration or importance and minimum attributes configured. Effectively, the crmsrv service wil run intwo nodes andhrsvc will run in one node.

C. Rebootlescrs cluster stack willbe tried inallthe duster nodes to resolve the issue.If this is notresolved, allnodes in thecluster get bounced to resolve the issues

D. Nothing happens because any service relocation is a major interruption to the clients who are connecting to the services.
