单选题You have three production databases, HRDB, FINDB, and ORGDB, that use the same ASM instance. At the end of the day, you execute the following command on the ASM instance to shut down: SQL shutdown immediate; What is the result of executing this command

第1题：

You are using an Automatic Storage Management （ASM） instance to manage the database files of your production database. After adding a new disk group to the ASM instance， you execute the following command：  ALTER DISKGROUP dg3 REBALANCE POWER 0； What would be the result of this command？（）

• A、The rebalancing of the disk group would be stopped.
• B、The rebalancing of the disk group would be completed as fast as possible.
• C、The command would result in an error because the value of POWER cannot be 0.
• D、The rebalancing of the disk group would be completed without affecting the disk group DG3.
• E、The command would result in an error because the disk groups cannot be manually rebalanced.

第2题：

• A、The ASM instance is shut down, but the other instances are still running.
• B、It results in an error because other database instances are connected to it.
• C、All the instances, including the ASM instance, are shut down in the IMMEDIATE mode.
• D、HRDB, FINDB, and ORGDB instances are shut down in the ABORT mode and the ASM instance is shut down in the IMMEDIATE mode.

第4题：

The ORACLE_SID environment variable is set to +ASM. ASMLIB is not used in the configuration. You executed the following command to startup the Automatic Storage Management (ASM) instance. SQL> STARTUP; Which two activities are performed during a successful start up operation? （）(Choose two.)

• A、The databases configured to use the ASM instance are mounted
• B、The disk groups are mounted as per the ASM_DISKGROUPS initialization parameter
• C、ASM starts the Oracle Cluster Synchronization Services (CSS) daemon if it is not started

第5题：

When an ASM instance receives a SHUTDOWN NORMAL command，what command does it pass on to all database instances that rely on the ASM instances disk groups？（）

• A、 TRANSACTIONAL
• B、 IMMEDIATE
• C、 ABORT
• D、 NORMAL

第6题：

Which of the following options is true about shutting down an Automatic Storage Management （ASM） instance？（）  

• A、 If the SHUTDOWN IMMEDIATE command is issued to the ASM instance， the ASM instance immediately shuts down.
• B、 If the SHUTDOWN ABORT command is issued to the ASM instance， the ASM instance will shut down all the database instances and then shut down immediately.
• C、 If the SHUTDOWN NORMAL command is issued to the ASM instance， before shutting down， the ASM instance waits for the dependent database instances to shut down.
• D、 If the SHUTDOWN TRANSACTIONAL command is issued to the ASM instance， the ASM instance passes the same SHUTDOWN command to the dependent database instances， but does not wait for any active transactions to complete before it shuts down.

第7题：

After executing the command alter diskgroup disk group2 drop disk dg2a； you issue the following command from the ASM instance：   Select group_number， count（*） from v$asm_operation；   What is the implication if the query against V$ASM_OPERATION returns zero rows？（）  

• A、 The drop disk operation is still proceeding and you cannot yet run the undrop disks operation.
• B、 The drop disk operation is complete and you can run the undrop disks command if needed.
• C、 The drop disk operation is complete and you cannot run the undrop disk command.
• D、 The query will fail since there is not a V$ASM_OPERATION view available in an ASM instance. 
• E、 None of the above is true.
