Oracle Real Application Clusters 12c Essentials : 1z0-432

You have completed a rolling conversion fromDNS to GNScluster resolution from the database andcluster resources end.The remaining are the configuration changes to be done from theclient side.
Which two items need to betaken into account to achieve a successful connection?

• A. For each client using VIP names, change the VIP name on eachclient sothat they use the same server VIP name, but with the domain namein thedomain delegated to GNS.
• B. There is no need to change anything in client configuration as the combination of TAF and ONSwillautomatically take care of reaching the correct nodes
• C. For each client using a SCAN, change the SCAN theclient uses so that theclient uses the SCAN in the domain delegated to GNS
• D. All the nodes in the cluster need to be bounced oneafter the otherinorder for the changes to be completed as it is not possible to do it online

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

You are preparing two Oracle Linux nodes, node1 and node2, for the installation of Oracle Grid Infrastructure, you plan to use the existing Linux users "grid" as Grid Infrastructure software.
What task must be performed before installing the Grid Infrastructure?

• A. No task must be performed.
• B. Change the user ID ofthe grid user in node1, node2, or both nodes to guarantee that the user IDs are equal
• C. Use another Linux user as "grid" might be used for other purposes.
• D. Add "users" to supplementary groups of "grid" in node1. Or, alternatively remove "users" from supplementary groups ofnode2 "grid."
• E. Change the user "grid' initial login group to "dba"

The DISK_REPAIR_TIME attribute has expired after a transient disk error. What happens next?

• A. Oracle ASM drops the disk.
• B. Nothing, it was only a warning. All the disks are OK
• C. This means that Oracle will use ASM Fast Mirror Resync to sync the rest of the disks.
• D. This means that the disk is repaired and is put backinthe ASM disk group.

You want to change an existingOracle Clusterware standard Cluster to an Oracle Flex Cluster Thereis Grid Naming Service (GNS) and Flex ASM configured right now.In what order do you need to take the following steps?
1.StopOracle Clusterware 2.Determine the current mode of thecluster 3.Ensure that the GNSisconfigured with a fixed VIP. 4.Change the mode of the cluster to be an Oracle Flex Cluster. 5.Use theOracle Automatic Storage Management Configuration Assistant (ASMCA) to
enable Oracle Flex ASMinthe cluster 6.Start Oracle Clusterware

• C. 2,3,5, 4, 1,6
• D. 1, 2,3, 4,5,6
