문제 #1

Which two statements are true concerning buffer states as shown in GV$BH.STATUS in Oracle 19c RAC? (Choose two.)

A. An xcur image is not shipped to another instance until commits occur for updated rows on the block.
B. A Pi block image may exist for a specific database block in only one instance.
C. An xcur block image may exist for a specific database block in only one instance.
D. An xcur image is not downgraded to a SCUR image for shipping to another instance until commits occur for updated rows on the block.
E. A CR image may get served from one instance to another to satisfy a read request.

문제 #2

Which two statements are true about High Availability NFS (HANFS)? (Choose two.)

A. HANFS' performance depends on the characteristics of the underlying ASM disks.
B. HANFS provides high availability in case of an NFS client failure.
C. HANFS provides high availability in case of cluster node failure.
D. NFS client requests are distributed by DNS in a round-robin fashion to the cluster nodes that export the NFS
E. HANFS does not depend on NFS services provided by the underlying operating system.

문제 #3

Examine this command and output:

Examine this command:

Which statement must be true for the successful execution of the second command?

A. The underlying advm volume must be configured with high redundancy.
B. The parent snapshot must be read-only.
C. The parent snapshot must be read/write.
D. The disk group compatibility attribute for advm must be set to 12. l or higher.

문제 #4

Secure Cluster Communication protects the cluster interconnect from common security threats when used together with Single Network Support. Secure Cluster Communication includes message digest mechanisms, protection against fuzzing, and uses Transport Layer Security (TLS) to provide privacy and data integrity between the cluster members.
Which statement is true about securing cluster interconnect communication?

A. Security for the cluster interconnect is invoked by auto-generated server certificates that will be assigned to each cluster node as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c.
B. Database administrators or cluster administrators must provide a valid server certificate and an Oracle Wallet for each node during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.
C. Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c and Database administrators or cluster administrators do not need to make any configuration changes for this feature.
D. Database administrators or cluster administrators must provide an encryption key during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.
E. Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c using an auto-generated encryption key that is stored locally on each node of the cluster in an Oracle Wallet and Database administrators or cluster administrators must provide a valid path for the Wallet file.

문제 #5

Disk group DGRP1 has these attributes:
1. Normal redundancy
2. Two failure groups FG1 and FG2 with two disks each
3. Compatibility settings set to 19.0
The FG1 failure group goes offline due to hardware failure.
Which two statements are true? (Choose two.)

A. Transactions on database objects stored in tablespaces in the dgrpi disk group fail.
B. New allocation units are not mirrored but changes to allocation units are tracked in the FG2 failure group.
C. New allocation units are mirrored in the FG2 failure group until FGl is restored and the disk group resvnchronized-
D. The redundancy is lowered until the FGl failgroup is restored and the disk group resynchronized.
