Q7. You plan to apply a patchset to a RAC database running on a two-node cluster.
The cluster has this configuration: Grid infrastructure release 12.1.0.1.0 RAC database release 12.1.0.1.0
All software installed on local file systems
The database is deployed on ASM disk groups.
Examine this list of possible tasks:
Apply the patchset to Grid Infrastructure by installing it in a new location. Stop all database instances.
Apply the database patchset in a new location.
Apply the database patchset on top of the existing ORACLE_HOME.
Start only one database instance in upgrade mode and run the upgrade script.
Start all database instances in upgrade mode and run the upgrade script.
Start all database instances and run the upgrade script. Start all database isntances.
Identify the required tasks in the correct order to apply the patchset with the least amount of down time.
A. 1, 3, 2, 5 and 8 B. 3, 2, 5 and 8
B. 1, 2, 3, 5 and 8

Q9. When installing Oracle Grid Infrastructure 12c, which three options exist for the configuration of Grid naming Service (GNS)?
A. using Shared GNS for the leaf nodes and local GNS for the hub nodes in a Flex Cluster
B. using Shared GNS running on another cluster
C. using Shared GNS for the hub nodes and local GNS for the leaf nodes in a Flex Cluster
D. creation of a new GNS for this cluster
E. using DHCP to assign Node Virtual IP addresses for nodes in the cluster
Answer: A,B,E
Q10. Your flex cluster has these attributes:
1.Hub nodes host01 and host02
2.Leaf nodes host03 and host04
3.Full Featured GNS is configured and running.
You attempt to run this command to add two more nodes to the cluster:
$ ./addnode.sh –silent “CLUSTER_NEW_NODES={host05,host06}” “CLUSTER_NEW_NODE_ROLES={hub,leaf}”
What is the result and the reason for this result?
A. It fails because no VIP was specified for the hub node host05.
B. It fails because hub and leaf nodes may not be added by the same execution of addNode.sh.
C. It fails because GNS doesn’t assign VIPs for leaf nodes and no VIP was specified in the command.
D. It succeeds because no VIP specification is required for leaf nodes and none need to be specified for hubnodes when using full featured GNS.
Answer: B
