D. All required background processes are started.
E. SYS can access the database.

Answer: A,D

Explanation:
A .True. Background processes (e.g., PMON) start.
B .False. Consistency checks require MOUNT.
C .False. Control files open in MOUNT.
D .True. SGA is allocated at startup.
E .False. SYS access requires OPEN.

NEW QUESTION # 49
You want to apply the principle of Least Privilege in all your live databases. One of your requirements is to revoke unnecessary privileges from all users who have them using Privilege Analysis. Which three types of analyses can be done using the DBMS_PRIVILEGE_CAPTURE package?

A. Analysis of privileges granted indirectly to a role that are then used by a user who has beengranted that role.
B. Analysis of all privileges used by all users but excluding administrative users in the database.
C. Analysis of all privileges used by all users including administrative users in the database.
D. Analysis of privileges that a user has on their own schema objects that they did not use.
E. Analysis of privileges that a user has on their own schema objects that they did use.
F. Analysis of privileges granted directly to a role that are then used by a user who has been granted that role.

Answer: A,D,E

Explanation:
A .True. Captures unused self-owned object privileges.
B .False. SYS is excluded from capture.
C .False. No exclusion option for admin users.
D .False. Direct role grants aren't separately analyzed.
E .True. Tracks indirect role privileges used.
F .True. Identifies used self-owned privileges.

NEW QUESTION # 50
Which two statements describe how Optimizer Statistics are collected?

A. Optimizer Statistics are collected automatically by an automatic maintenance job that runsduring predefined maintenance windows.
B. Optimizer Statistics are collected in real-time as data is inserted, deleted, or updated.
C. Optimizer Statistics can be manually collected at multiple levels using DBMS_STATS.GATHER_*_STATS PL/SQL procedures.
D. Optimizer Statistics are collected automatically by Automatic Workload Repository (AWR) Snapshot.
E. Optimizer Statistics are collected by the Statistics Advisor.

Answer: A,C

Explanation:
Optimizer Statistics drive the cost-based optimizer's query plans. Let's dissect each option:
A . Optimizer Statistics are collected automatically by an automatic maintenance job that runs during predefined maintenance windows.
True. Oracle 23ai uses the AutoTask framework to gather stats automatically during maintenance windows (e.g., nightly 10 PM-2 AM). The GATHER_STATS_PROG job, managed by DBMS_AUTO_TASK_ADMIN, collects stats for stale or missing objects.
Mechanics:Controlled by STATISTICS_LEVEL=TYPICAL (default) and the DEFAULT_MAINTENANCE_PLAN. It prioritizes objects with >10% changes (stale stats) or no stats.
Practical Use:Ensures stats are current without manual intervention, critical for dynamic workloads.
Edge Case:Disabled if STATISTICS_LEVEL=BASIC or the job is manually disabled via DBMS_AUTO_TASK_ADMIN.DISABLE.
B . Optimizer Statistics are collected in real-time as data is inserted, deleted, or updated.
False. Stats aren't updated in real-time; this would be too resource-intensive. Instead, Oracle tracks changes (e.g., via DBA_TAB_MODIFICATIONS) and updates stats periodically via AutoTask or manually. Real-time stats exist in 23ai for specific cases (e.g., GATHER_TABLE_STATS with REAL_TIME_STATS), but it's not the default.
Why Incorrect:Real-time collection would degrade performance for OLTP systems, contradicting Oracle's batch approach.
C . Optimizer Statistics can be manually collected at multiple levels using DBMS_STATS.GATHER_*_STATS PL/SQL procedures.
True. The DBMS_STATS package offers granular control: GATHER_TABLE_STATS, GATHER_SCHEMA_STATS, GATHER_DATABASE_STATS, etc., allowing stats collection for tables, schemas, or the entire database.
Mechanics:Example: BEGIN DBMS_STATS.GATHER_TABLE_STATS('HR', 'EMPLOYEES'); END;. Options like ESTIMATE_PERCENT and DEGREE fine-tune the process.
Practical Use:Used for immediate stats updates post-DML or for custom schedules outside maintenance windows.
Edge Case:Overuse can lock stats (e.g., FORCE=TRUE), requiring careful management.
D . Optimizer Statistics are collected by the Statistics Advisor.
False. The Statistics Advisor (new in 23ai) analyzes and recommends stats improvements but doesn't collect them. Collection is still via DBMS_STATS or AutoTask.
Why Incorrect:It's a diagnostic tool, not an executor.
E . Optimizer Statistics are collected automatically by Automatic Workload Repository (AWR) Snapshot.
False. AWR snapshots capture performance metrics (e.g., wait times), not optimizer stats. Stats collection is a separate process via AutoTask or manual commands.
Why Incorrect:AWR and stats collection serve distinct purposes-monitoring vs. optimization.

NEW QUESTION # 51
Which three statements are true about Enterprise Manager Cloud Control?

A. It provides management for Oracle middleware.
B. It is available to manage a database only when that database is open.
C. It uses a web-based console built into the Oracle database using XML DB.
D. It provides management for Oracle-engineered systems.
E. It is integrated with My Oracle Support.

Answer: A,D,E

Explanation:
A .True. Integrates with MOS for patches and support.
B .True. Manages Exadata, etc.
C .True. Covers WebLogic and other middleware.
D .False. Web-based, but not built into the DB.
E .False. Can manage stopped instances via agents.

NEW QUESTION # 52
You execute this command: CREATE BIGFILE TABLESPACE big_tbs DATAFILE '/u01/oracle/data/big_f1.dbf' SIZE 20G; Sufficient storage is available in filesystem /u01. Which two statements are true about the BIG_TBS tablespace?

A. It will always have a 32K blocksize.
B. AUTOEXTEND is possible for the datafile.
C. It must be bigger than the largest SMALLFILE tablespace.
D. It will be a dictionary-managed tablespace by default.
E. Additional data files may not be added.

Answer: B,E

Explanation:
A .False. LMT is default in 23ai.
B .True. Bigfile tablespaces have one data file only.
C .True. AUTOEXTEND works with bigfile data files.
D .False. Block size defaults to DB_BLOCK_SIZE (e.g., 8K).
E .False. No size comparison requirement.
