E .False. Defaults to $ORACLE_BASE or /u01/app/oracle if unset.

NEW QUESTION # 69
What are Optimizer Statistics?

A. Optimizer Statistics are part of system performance statistics stored in AWR required for calculating SQL execution plans.
B. Optimizer Statistics are statistics about data distribution within Oracle Datafiles.
C. Optimizer Statistics are a set of data distribution statistics collected in real time as data is inserted, deleted, or updated, which are stored in AWR and used for generating SQL execution plans.
D. Optimizer Statistics are table, column, index, and system statistics used for generating efficient SQL execution plans.

Answer: D

Explanation:
A .False. Not real-time; collected periodically.
B .False. Not about datafile distribution.
C .True. Includes table, column, index stats for plan generation.
D .False. Stored in data dictionary, not AWR.

NEW QUESTION # 70
Which resource plan is used to manage the resources for the predefined maintenance window?

A. The SYS_GROUP consumer resource group policies define the resources assigned ...
B. By default, all predefined maintenance windows use the DEFAULT_MAINTENANCE_PLANresource plan, and automated maintenance tasks run under subplan called ORA$AUTOTASK.
C. The resources used by the predefined maintenance window can only be adjusted if you create a new resource plan in Resource Manager ...
D. The predefined maintenance window starts automatically with 20% of the system resources ...

Answer: B

NEW QUESTION # 71
You must create a tablespace of nonstandard block size in a new file system and plan to use this command: CREATE TABLESPACE ns_tbs DATAFILE '/u02/oracle/data/nstbs_f01.dbf' SIZE 100G BLOCKSIZE 32K; The standard block size is 8K, but other nonstandard block sizes will also be used. Which two are requirements for this command to succeed?

A. The /u02 file system must have at least 100G space for the datafile.
B. DB_32K_CACHE_SIZE must be less than DB_CACHE_SIZE.
C. DB_32K_CACHE_SIZE must be set to a value that can be accommodated in the SGA.
D. DB_32K_CACHE_SIZE should be set to a value greater than DB_CACHE_SIZE.
E. The operating system must use a 32K block size.

Answer: A,C

Explanation:
A .False. No such restriction exists; DB_32K_CACHE_SIZE is independent of DB_CACHE_SIZE.
B .True. A nonstandard block size (32K) requires a corresponding cache (DB_32K_CACHE_SIZE) set to a non-zero value within SGA limits.
C .False. OS block size is irrelevant; Oracle manages its own block sizes.
D .False. No requirement for it to exceed DB_CACHE_SIZE.
E .True. The file system must have 100G available for the datafile.

NEW QUESTION # 72
Which two statements are true regarding Oracle database space management within blocks managed by Automatic Segment Space Management (ASSM)?

A. Update operations always relocate rows into blocks with free space appropriate to the length of the row being updated.
B. PCTFREE defaults to 10% for all blocks in all segments for all compression methods.
C. ASSM assigns blocks to one of the four fullness categories based on what percentage of the block is allocated for rows.
D. The first block with enough free space to accommodate a row being inserted will always be used for that row.
E. Insert operations always insert new rows into blocks with free space appropriate to the length of the row being inserted.

Answer: C,E

Explanation:
A .True. ASSM categorizes blocks (e.g., 0-25%, 25-50%) for efficient space use.
B .False. Updates may cause chaining/migration, not always relocation.
C .True. ASSM optimizes inserts into suitable blocks.
D .False. ASSM uses a bitmap, not necessarily the first block.
E .False. PCTFREE is segment-specific, not universally 10%.
