Which three components are integral parts of High Availability NFS (HANFS)?

Application VIP
DHCP
ExportFS
HAVIP
NFS
HAIP

Correct answer: CDE

Explanation:

CD: In addition to ACFS/ADVM and ASM, HANFS also relies on new Oracle 12.1 Clusterware (CRS) resources, namely the HAVIP and the ExportFS.DE: High Availability Network File Storage (NFS) for Oracle Grid Infrastructure provides uninterrupted service of NFS V2/V3/V4 exported paths by exposing NFS exports on Highly Available Virtual IPs (HAVIP) and using Oracle Clusterware agents to ensure that the HAVIPs and NFS exports are always online.References: https://docs.oracle.com/database/121/OSTMG/GUID-4D7A5911-8FA6-47DC-98BB-593B2C90D43E.htm#OSTMG95489http://www.oracle.com/ocom/groups/public/@otn/documents/webcontent/2011281.pdf

You just added an ASM disk to the DATA diskgroup.

Which two can be used to monitor the rebalancing?

ams_cmd lsop
v$asm_disk
v$asm_operation
v$asm_diskgroup
v$session_longops
amscmd lsdg

Correct answer: AC

Examine this command:

SQl> CREATE DISKGROUP RECO HIGH REDUNDANCY:

FAILGROUP fgrpl1 DISK

‘/dev/disk1’ NAME disk1,

‘/dev/disk2’ NAME disk2,

‘/dev/disk3’ NAME disk3,

FAILGROUP fgrpl2 DISK

‘/dev/disk4’ NAME disk4,

‘/dev/disk5’ NAME disk5,

‘/dev/disk6’ NAME disk6,

FAILGROUP fgrpl3 DISK

‘/dev/disk7’ NAME disk7,

‘/dev/disk8’ NAME disk8,

‘/dev/disk9’ NAME disk9,

ATTRIBUTE ‘au_size’=’4M’,

‘compatible.asm’ = ’12.1’,

‘compatible.rdbms’ = ’12.1’,

‘compatible.advm’ = ’12.1’,

‘content_type’ = ‘recovery’;

Which three statements are true about this disk group?

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

Correct answer: ADF

Explanation:

For a diskgroup with HIGH redundancy in a diskgroup and the template attribute set to MIRROR it will be a 3-way mirror. Note:When a file is created, redundancy and striping attributes are set for that file based on an explicitly named template or the system template that is the default template for the file type. Incorrect Answers:B: Compatible.rdbms is set to 12.1, not to 10.1.C: The compatible attributes cannot be reversed.E: FRA (Flash Recovery Area) is not referenced in the creation of the diskgroup.
