Question 267

To implement Automatic Management (AMM), you set the following parameters:

When you try to start the database instance with these parameter settings, you receive the following error message:
SQL > startup
ORA-00824: cannot set SGA_TARGET or MEMORY_TARGET due to existing internal settings, see alert log for more
information.
Identify the reason the instance failed to start.

A.The PGA_AGGREGATE_TARGET parameter is set to zero.

B.The STATISTICS_LEVEL parameter is set to BASIC.

C.Both the SGA_TARGET and MEMORY_TARGET parameters are set.

D.The SGA_MAX_SIZE and SGA_TARGET parameter values are not equal.

Question 268

Examine the memory-related parameters set in the SPFILE of an Oracle database:

Which statement is true?

A.The value of the MEMORY_TARGET parameter cannot be changed dynamically.

B.Memory is dynamically re-allocated between the SGA and PGA as needed.

C.Only SGA components are sizedautomatically.

D.The size of the PGA cannot grow automatically beyond 500 MB.

Question 269

A database is stored in an Automatic Storage Management (ASM) disk group, disk group, DGROUP1 with SQL:

There is enough free space in the disk group for mirroring to be done.
What happens if the CONTROLLER1 failure group becomes unavailable due to error of for maintenance?

A.Transactions and queries accessing database objects contained in any tablespace stored in DGROUP1 will fall.

B.The data in the CONTROLLER1 failure group is copied to the controller2 failure group and rebalancing is initiated.

C.Mirroring of allocation units will be done to ASM disks in the CONTROLLER2 failure group until the CONTROLLER1 for failure group is brought back online.

D.Transactions accessing database objects contained in any tablespace stored in DGROUP1 will fail but queries will succeed.

E.ASM does not mirror any data until the controller failure group is brought back online, and newly allocated primary allocation units (AU) are stored in the controller2 failure group, without mirroring.

Question 270
