          ‘compatible.rdbms’ = ’11.2’, 
          ‘compatible.advm’ = ’11.2’, 
          ‘content_type’ = ‘recovery’; 
Which two statements a true about this disk group, created using Grid Infrastructure 12.1?

  • A: Each disk in each of the three fail groups is a mirror of the corresponding disk of the other two failure groups.
  • B: File created in this disk group always has two copies for each allocation unit: one primary and one secondary.
  • C: It can contain ASM Dynamic Volume Manager (ADVM) volumes.
  • D: Any database instance with the COMPATIBLE parameter set to 11.2 or higher can access it.
  • E: The ASM compatible attributes can be changed to 11.1 for this disk group.



Question 5
Which two statements are true about the UNDROP clause of the ALTER DISKGROUP statement?

  • A: It cancels pending drops of disks dropped using the DROP DISKGROUP command.
  • B: A disk cannot be undropped as a result of a drop diskgroup.
  • C: It automatically unmounts the disks after successfully undropping them.
  • D: It is not possible to cancel pending drops of disks dropped using the force option.



Question 6
Examine the output of the asmcmd and srvct1 commands:

  

Then you execute this command:
$ srvctl relocate asm – currentnode host03 –targetnode host02 
Which three statements are true regarding the execution of this command based on the output shown?

  • A: It fails because an ASM instance is not configured to run on HOST02.
  • B: It succeeds and starts an ASM instance on HOST02 and shuts down the ASM instance on HOST03.
  • C: It succeeds and 12c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST02.
  • D: It fails because the ASM instance has not been shut down first on HOST03.
  • E: It succeeds and starts an ASM instance on HOST02 but the ASM instance on HOST03 is not shut down until all connected clients disconnected.
  • F: It succeeds and 12c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST01.



Question 7
Which three statements are true about ASM Cloud File System (ACFS) encryption?

  • A: A copy of an encrypted file is not encrypted unless it is created in an encrypted directory.
  • B: acfsutil encr init is used to establish role separation between encryption managers and encryption auditors.
  • C: acfsutil encr off can be run by an encryption manager who may not have system administrator privileges.
  • D: acfsutil encr on can be used to specify the encryption key length for a directory or file.
  • E: An ACFS snapshot can be ACFS encrypted.



Question 8
Which two statements are true concerning ASM diskgroups using disks with a 4k sector size?

  • A: Their COMPATIBLE.ASM attributes must be set to 12.1 or higher.
  • B: Their COMPATIBLE.ASM attributes must be set to 11.2 or higher.
  • C: Performance of ACFS is improved by using these diskgroups.
  • D: Their COMPATIBLE.RDBMS attributes must beset to 11.2 or higher.
  • E: Their sector size attributes can be changed using the ALTER DISKGROUP command.



Question 9
Examine the output of this command:
   ASMCMD> volinfo –G ACFS -a 
   Diskgroup Name: ACFS
   Volume Name: VOL1
   Volume Device: /dev/asm/vol1-280
   State: ENABLED
   Size (MB): 248
   Resize Unit (MB): 32
   Redundancy: MIRROR
   Stripe Columns: 4
   Stripe Width (K): 128
   Usage: ACFS
   Mountpath: /u01/app/grid/acfsmount
The ACFS disk group is a normal redundancy disk group with 5 GB of free space. 
To increase the size of the ACFS file system, you execute this command as the root user:
   $ /sbin/acfsutil size +200M /u01/app/grid/acfsmount 
Which two statements are true regarding the outcome of this command?

  • A: It resizes VOL1.
  • B: It fails to resize the filesystem because it must be unmounted before resizing.
  • C: It fails to resize VOL1 because it must be executed as a user belonging to the SYSASM group.
  • D: It succeeds but leaves the filesystem unmounted.
  • E: It resizes the filesystem mounted on /u01/app/grid/acfsmount.



Question 10
You support a three-instance, policy-managed, multitenant RAC database CDB1 with two PDBs PDB_1 and PDB_2. 
It runs on an eight-node cluster and a serverpool prod_pool has three servers. 
Examine these commands executed on HOST01:
   $ srvctl add service –db CDB1 –pdb PDB_1 –service HR –serverpool prod_pool 
   $ srvctl start service –db CDB1 –service HR 
   $ srvctl stop service –db CDB1 –service HR 
Which two statements are true?

  • A: HR is uniformly managed across all instances in prod_pool.
  • B: srvctl stop service only closes PDB_1 in the instance on HOST01.
  • C: srvctl stop service closes PDB_1 on all CDB1 instances.
  • D: srvctl stop service prevents logins for HR only to CDB1 on HOST01.
  • E: srvctl stop service prevents logins to any instance of CDB1 using service HR.
  • F: HR is available on a single instance of prod_pool.
