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

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

You must replace a failed disk that was dropped from a disk group.
You want the rebalance operation to occur with minimal performance impact.
Which two options exist to achieve this? (Choose two.)

• A.Use the WAIT clause with the ALTER DISKGROUP command.
• B.Increase the value of the DISK_REPAIR_TIME attribute for the disk group.
• C.Decrease the value of the DISK_REPAIR_TIME attribute for the disk group.
• D.Make sure that the ASM_POWER_LIMIT parameter is set to 1 before rebalancing the disk group.
• E.Set the POWER clause to 1 in the ALTER DISKGROUP command.

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

Examine this command:
SQl> CREATE DISKGROUP RECO HIGH REDUNDANCY:
FAILGROUP fgrp1 DISK
'/dev/disk1' NAME disk1,
'/dev/disk2' NAME disk2,
'/dev/disk3' NAME disk3,

'compatible.asm' = '12.1',
'compatible.rdbms' = '12.1',
'compatible.advm' = '12.1',
'content_type' = 'recovery';
Which three statements are true about this disk group?

• A.Any database instance with the COMPATIBLE parameter 10.1 and higher can use it.
• B.The RECO diskgroup may only be used for the FRA.
• C.Files created using a template with the redundancy attributes set to MIRROR will have three-way Mirroring.
• D.The Compatible attribute values of the disk group can be changed to lower values.
• E.Files created using a template with the redundancy attribute set to HIGH will have three-way mirroring.
• F.Files created in it have three copies for each allocation unit.

Your four-node cluster runs Oracle 12c Clusterware and supports a mix of RAC databases from Oracle 10g Release 2 to Oracle 12c Release 1.
All databases have one or more services defined.
The Oracle 10g Release 2 database clients connect to the database instances using the public VIP.
The Oracle 11g Release 2 and 12c Release 1 clients connect to the database instances using the Single Client Access Name (SCAN).
You must change the public VIPS.
Which three steps must be done to change the VIPs on host01, the first node in the cluster? (Choose three.)

• A.Use oifcfg setif to start the VIP on host01.
• B.Use srvctl start vip to start the VIP on host01.
• C.Use srvctl modify nodeapps to change the VIP on host01.
• D.Use oifcfg setif to stop the VIP on host01.
• E.Use srvctl stop vip to stop the VIP on host01.
