Demo Questions
Question 1
Examine the output of this command:
ASMCMD> volinfo –G ACFS -a
Diskgroup Name: ACFS
Volume Name: VOL1
Volume Device: /dev/asm/vol1-280
State: ENABLED
Size (MB): 248
Resize Unit (MB): 32
Redundancy: MIRROR
Stripe Columns: 4
Stripe Width (K): 128
Usage: ACFS
Mountpath: /u01/app/grid/acfsmount
The ACFS disk group is a normal redundancy disk group with 5 GB of free space.
To increase the size of the ACFS file system, you execute this command as the root user:
$ /sbin/acfsutil size +200M /u01/app/grid/acfsmount
Which two statements are true regarding the outcome of this command?
- It resizes VOL1.
- It fails to resize the filesystem because it must be unmounted before resizing.
- It fails to resize VOL1 because it must be executed as a user belonging to the SYSASM group.
- It succeeds but leaves the filesystem unmounted.
- It resizes the filesystem mounted on /u01/app/grid/acfsmount.
Correct answer: AD
Question 2
You support a three-instance, policy-managed, multitenant RAC database CDB1 with two PDBs PDB_1 and PDB_2.
It runs on an eight-node cluster and a serverpool prod_pool has three servers.
Examine these commands executed on HOST01:
$ srvctl add service –db CDB1 –pdb PDB_1 –service HR –serverpool prod_pool
$ srvctl start service –db CDB1 –service HR
$ srvctl stop service –db CDB1 –service HR
Which two statements are true?
- HR is uniformly managed across all instances in prod_pool.
- srvctl stop service only closes PDB_1 in the instance on HOST01.
- srvctl stop service closes PDB_1 on all CDB1 instances.
- srvctl stop service prevents logins for HR only to CDB1 on HOST01.
- srvctl stop service prevents logins to any instance of CDB1 using service HR.
- HR is available on a single instance of prod_pool.
Correct answer: AE
Question 3
Which three statements are true about the services created when the DBCA is used to create a RAC database?
- They can be policy managed for a multitenant database.
- Singleton services are not permitted for multitenant databases.
- A server-pool must be created with SRVCTL before creating a policy-managed RAC database that uses that server-pool for a service.
- Policy-managed services specified for a database allow the creation of a new server pool using DBCA.
- They can be administrator managed for a multitenant database.
Correct answer: ADE
Explanation:
Because policy-managed configuration was selected, the server pool to host the new CDB must be defined. Choose between using an existing server pool or creating a new one and specifying the detail of the new server pool to be used by the CDB. Policy-managed deployments facilitate consolidation. In the case of schema consolidation, where multiple applications are being hosted in a single database (CDB) separated into PDBs, since server pools determine which services run together or separately, you can configure and maintain required affinity or isolation of PDB services. Managing a policy-managed database requires less configuration and reconfiguration steps than an administrator-managed one with respect to creation, sizing, patching, and load balancing. Also, because any server in the server pools within the cluster can run any of the CDB instances and PDB services, you do not have to create and maintain CDB instance-to node-name mappings and PDB service-to-node-name mappings.
