Q1. You administer a six-instance, policy-managed, multitenant RAC database CDB1 with three PDBs: PDB_1, PDB_2 and PDB_3.
Server pool prod_pool has a cardinality of three and all six hosts of the cluster app.
Examine these commands executed on HOST01:
$ srvctl add service –db CDB1 –pdb PDB_1 service AR –serverpool prod_pool –cardinality singleton $ srvctl start service –db CDB1 –service AR
Which two statements are true regarding the AR service?
A. AR runs as a singleton service in the server pool prod_pool and the AR service is available in each of theCDB1 instances.
B. AR is available on any one available CDB1 instance in prod_pool at any one time.
C. AR can fail over to any one of the available CDB1 instances.
D. AR is available only on the CDB1 instance on HOST01.
E. AR can fail over to any other available CDB1 instance in prod_pool.

B. All servers in a new cluster installation belong to the generic server pool.
C. The server pool contains servers that host administrator-defined high availability resources.
D. Server pools must be managed with the srvctl utility for servers hosting a database.
E. All servers in a new cluster installation belong to the free server pool.
Q5. Which three statements are true about Server Categorization in Oracle 12c Clusterware?
A. All server attributes that may be used to determine the server category are discovered automatically byOracle Clusterware.
B. Different Hub nodes in a flex cluster may belong to separate administrator-defined categories.
C. All hub nodes in a flex cluster belong to the same Oracle-supplied category.
D. A server may be added to only one category using the crsctl utility.
E. All leaf nodes in a flex cluster belong to the same Oracle-supplied category.

Q6. Which two statements are true about initialization parameters for Clustered ASM instances?
A. A change to ASM_DISKSTRING requires a restart of all ASM instances for the change to take effect.
B. ASM_POWER_LIMIT controls he number of RDBMS instances that can access a disk group while it isbeing rebalanced.
C. The ASM_DISKGROUP parameter is optional.
D. The default value of INSTANT_TYPE is ASM.
E. The maximum value of ASM_POWER_LIMIT is 1024.
Q7. Which four statements are true concerning the upgrading of Oracle Grid Infrastructure 12c?
A. The ORACLE_HOME environment variable must be set to the Grid Infrastructure home directory in theinstallation owner’s environment.
B. The upgrade must be done in-place.
C. The upgrade must be done out of place.
D. Upgrade validation may be done using the Oracle Universal Installer which in turn invokes the built-incluster verification utility.
E. The cluster verification utility cluvfy.sh can verify that the cluster is ready for an upgrade.
F. The ORACLE_SID environment variable must be set to the SID of the ASM instance in the installationowner’s environment.
G. The cluster verification utility cluvfy.sh can generate fixup scripts to run on all nodes of the cluster.
Q8. Examine this output: ASMCMD> volinfo – G ACFS –a Diskgroup Name: ACFS Volume Name: VOL1 Volume Device: /dev/asm/vol1-280
Size (MB): 2048
Resize Unit (MB): 32
Stripe Columns: 4
Stripe Width (K): 128
The ACFS disk group has 10 GB free space and the file system is currently mounted.
You execute this command to increase the volume size: ASMCMD >volresize –G ACFS –s
Which statement is true regarding the outcome?
A. It succeeds
B. It fails because the file system must be unmounted before resizing.
C. It fails because resizing a volume containing an ACFS file system must be performed using ACFSUTIL.
D. It succeeds but the file system is automatically unmounted.
E. It fails because the –f option is not specified.
