A customer is using the policy-managed database by name RACDB on a 4-node cluster. The server names in the Cluster are: dasher, vixen, comet, and dancer. There are two server pools defined, frontoffice and backoffice. The attributes are as follows: ServerpoolImportance MinMax Frontoffice1022 BackOffice512 There are two uniform services being created, crmsrv and hrsrv. crmsrv is being assigned to serverpoolfrontoffice and hrsrv is assigned to backoffice. Currently, all four nodes are up and running. The database and its services are running as follows: The serverpoolfronoffice, which is running the crmsrv service is being run on the dasher and vixen hosts. The serverpoolbackoffice, which is running hrsvc service is being run on comet and dancer hosts. What happens when the dasher node fails?
Nothing happens because any service relocation is a major interruption to the clients who are connecting to the services.
You have recently completed building an 8-node 12cR1 RAC cluster, and you are now seeing a lot of instability, congestion, and network packet losses in the network. Which two items related to the private interconnect could have caused these issues?

In what order do you need to take the following steps? 1. Stop Oracle Clusterware. 2. Determine the current mode of the cluster. 3. Ensure that the GNS is configured with a fixed VIP. 4. Change the mode of the cluster to be an Oracle Flex Cluster. 5. Use the Oracle Automatic Storage Management Configuration Assistant (ASMCA) to enable Oracle Flex ASM in the duster. 6. Start Oracle Clusterware.
2, 3, 4, 5, 1, 6
Which tasks and in which order must be performed, before you can change the mode of a standard cluster to Flex?
1. Clusterware must be stopped on each node. 2. New Application VIPs must be created. 3. You must ensure that the GNS is configured with a fixed VIP. 4. Clusterware must be started on each node.
Which statement about the server Flex ASM is incorrect?
Flex ASM requires an ASM instance on each cluster node running an Oracle Database instance.
What is the mandatory step for a media recovery of RAC 12cR1 database with encrypted tablespaces?
You must relocate the sqlnet.ora file and remove it from $ORACLE_HOME/network/admin.
