• Question 52:

  Oracle 12cR1 Flex Cluster introduces a new topology, which allows for a higher level of scalability. Which four statements accurately describe the new topology's properties?

  A. Hub and Leaf topologies allow tightly and loosely coupled server membership

  B. Hub and Leaf topologies support implicit Server Pools.

  C. Leaf servers are standard as in previous versions.

  D. Leaf servers are light-weight, no shared storage, no peer-to-peer communication and dedicated to application service.

  E. Hub servers do not support Oracle ASM.

  Correct Answer: ABDF

• Question 53:

  Which statement accurately describes the benefit of the policy-managed database feature with Oracle RAC 12cR1?

  A. It protects against cascade failures due to network usage. It migrates workload isolation to specific pools. Less important workloads shut down immediately.

  B. It protects against cascade failures due to load. It ensures that workload isolation is balanced between pools. Less important workloads start transactionally

  C. It protects against cascade failures due to load. It ensures workload isolation between pools. Less important workloads shut down transactionally

  D. It protects against cascade failures due to load. It ensures workload isolation between pools. Less important workloads shut down and start uniformly.

  E. It protects against cascade failures due to load. It ensures workloads are not isolated between pools. Less important workloads shut down transactionally.

  Correct Answer: C

• Question 54:

  Identify the correct command to create the salesrep seivice for the PDB salespdb in the RAC 12cR1 CDB with DB_UNIQUE_NAME mycdb.

  A. Srvct1 add service -db mycdb -service salesrep -pdb create salespdb

  B. Srvct1 add service -db mycdb -service salesrep -pdb service salespdb

  C. Srvct1 add service -db mycdb -service salesrep -pdb salespdb

  D. Srvct1 add service -db mycdb -service salesrep -pdb service salespdb

  Correct Answer: C

• Question 55:

  Identify the incorrect statement about server pools.

  A. Server pools divide a cluster into logical groups of servers in which the application can be a database or non database.

  B. An application is considered a singleton when it runs on a single server in a pool. The database administrator must use the CRSCTL utility to create and manage clusters that contain Oracle RAC databases

  C. Oracle Default Server Pools are defined as FREE and GENERIC Server Pools.

  D. Database administrators can create and manage server pools that will contain Oracle RAC databases by using the SRVCTL utility.

  Correct Answer: C

• Question 56:

  A node is evicted from a three-node cluster due to poor latency of the underlying storage Which two statements are correct in describing the instance recovery process?

  A. Perform a restore of archive redo from flash recovery area to recover database

  B. Upon startup, the SMON/LMS processes perform instance crash recovery.

  C. Upon startup of failed instance, the SMON process performs instance crash recovery by using checkpoints to determine which data needs to be append to data files.

  D. User intervention is not required.

  E. Upon startup, PMON (process monitor) performs instance crash recovery automatically User intervention is not required

  Correct Answer: CD

• Question 57:

  Which new syntax has been introduced in ASM release 12cR1?

  A. Alter diskgroup DATA replace disk data_0001 with '/dev/disk02';

  B. Alter diskgroup DATA offline quorum disk data_0001 drop after 1 m;

  C. Alter diskgroup DATA set ownership owner = oracle for file '/dev/disk02';

  D. Alter diskgroup DATA drop disk '/dev/disk02' force;

  Correct Answer: A

• Question 58:

  You are talking to the network admin team about the Interconnect network in Oracle RAC and Clusterware. Which statement about the Private interconnect interface is incorrect?

  A. Oracle RAC and Oracle ASM instances use the private interconnect for inter-instance communication.

  B. Oracle Clusterware uses the private interconnect to exchange Clusterware-related messages among its nodes.

  C. It supports both IPv4 and IPv6.

  D. It supports redundant network interfaces for load balancing and high availability.

  Correct Answer: C

• Question 59:

  Which command can be used to create an Oracle ACFS file system resource?

  A. crsct1 create resource -t filesystem -f /dev/asm/ -m /

  B. srvct1 add filesystem -m / -d /dev/asm/

  C. asmcmd fscreate - - resource ACFS mount / -- file/dev/asm/

  D. srvct1 create resource -fs/dev/asm/ -mount /

  E. SQL > alter system add filesystemdevice = `/dev/asm/'mount_dir = `/';

  Correct Answer: B

• Question 60:

  What device path do you have to specify in ASM, if you want to use the multipath device?

  /dev/sdd = first path

  /dev/sdd = second path

  /dev/multipatha = path of the multipath OS driver

  A. Only /dev/sdc is enough, because asmlib knows it is a multipath device.

  B. /dev/sdc as disk group and /dev/sdd as failure group.

  C. You need to specify all the three devices and only then ASM will know this is a multipath device.

  D. Only /dev/multipatha is enough.

  Correct Answer: D
