B. at least one for the storage network 

C. at least one for the interconnect

Q6. Which three statements are true about Oracle Clusterware components, architecture, and behavior? 

A. The Cluster Ready Services Daemon (CRSD) is responsible for monitoring and maintaining the availabilityof cluster resources defined in the Oracle Local Repository file (OLR). 

B. All cluster nodes can write or read from the Oracle Clusterware Repository (OCR) file at the same time. 

C. The Oracle High Availability Services Daemon (OHASD) is responsible for monitoring and maintaining theavailability of the Clusterware stack on a cluster node. 

D. Voting disks stored in Automatic Storage Management (ASM) can be discovered or used even if the ASM instance on a cluster node is down. 

E. The Cluster Synchronization Services Daemon (CSSD) must connect to the cluster by accessing theOracle Clusterware Repository (OCR) file before the Oracle High Availability Services Daemon (OHASD) is started.

Answer: A,C,E 


Q7. Which three statements are true regarding ACFS snapshots in Oracle 12c ASM? 

A. They are contained in a directory on the same volume as their parent file system. 

B. All ACFS snapshot operations for all filesystem are serialized clusterwide. 

C. You can create a snapshot from an existing snapshot. 

D. They can be administered using ASMCMD. 

E. They can only be accessed when the file system is mounted. 

F. They are always point-in-time copies of the parent file system. 

Answer: B,C,E 

Explanation: 

All Oracle ACFS snapshot operations are serialized clusterwide in the kernel. you chose to create a snapshot image on an existing snapshot group, select a snapshot group from the existing snapshot group table (make sure you select a snapshot group that has not reached its maximum limit of snapshot images). 

Before you can access the files on a file system, you need to mount the file system.

Q8. Examine this output: ASMCMD> volinfo – G ACFS –a Diskgroup Name: ACFS Volume Name: VOL1 Volume Device: /dev/asm/vol1-280 

State: ENABLED 

Size (MB): 2048 

Resize Unit (MB): 32 

Redundancy: MIRROR 

Stripe Columns: 4 

Stripe Width (K): 128 

Usage: ACFS 

Mountpath: /u01/app/grid/acfsmount 

The ACFS disk group has 10 GB free space and the file system is currently mounted. 

You execute this command to increase the volume size: ASMCMD >volresize –G ACFS –s 

3G VOL1 

Which statement is true regarding the outcome? 

A. It succeeds 

B. It fails because the file system must be unmounted before resizing. 

C. It fails because resizing a volume containing an ACFS file system must be performed using ACFSUTIL. 

D. It succeeds but the file system is automatically unmounted. 

E. It fails because the –f option is not specified.

Q9. Which three statements are true concerning the Automatic Workload Repository (AWR) in a RAC environment? 

A. Taking an AWR snapshot in a RAC database captures data from all instances that have the databaseopened. 

B. Taking an AWR snapshot in a RAC database captures data from the local instance only. 

C. Data captured by an AWR is aggregated across all instances before being stored in the database. 

D. The awr_snapshot_time_offset parameter specifies the number of seconds each instance waits after thetop of the hour before taking its AWR snapshot. 

E. AWR snapshots are created when control_management_pack_access is set to “none” 

Answer: C,D,E 


Q10. Which two statements are true regarding server-side connect-time load balancing for a RAC database when using SCAN listeners?

C. The service’s connection load balancing goal must be manually configured to enable server-side connect-time load balancing. 

D. It’s enabled only when LOAD_BALANCE=YES is included in the TNS entry used by the client. 

E. Server-side load balancing requires the REMOTE_LISTENER to point to the SCAN. 

Answer: C,E
