Quiz Oracle - 1Z1-182 - Oracle Database 23ai Administration Associate –Valid Reliable Braindumps Questions

There is no shortcut to Oracle 1Z1-182 exam questions success except hard work. You cannot expect your dream of earning the Oracle Database 23ai Administration Associate CERTIFICATION EXAM come true without using updated study material Oracle Database 23ai Administration Associate (1Z1-182) exam questions. Success in the 1Z1-182 exam adds more value to your resume and helps you land the best jobs in the industry.

Oracle Database 23ai Administration Associate Sample Questions (Q50-Q55):

NEW QUESTION # 50
What is the result of the following command? ALTER PLUGGABLE DATABASE PDB1 DISCARD STATE;

A. PDB1 is reverted to its default properties, which includes not to automatically open after a CDB restart.
B. It is unnecessary if the PDB is in the process of being upgraded.
C. PDB1 is reverted to its default properties, which includes automatic opening after a CDB restart.
D. It should be used whenever PDB1 open mode needs to be changed.

Answer: A

Explanation:
A .False. DISCARD STATE isn't tied to upgrades; it resets PDB startup behavior.
B .True. Discards saved state, reverting PDB1 to manual open mode (not auto-open) after CDB restart.
C .False. Default is not auto-open; it's manual unless explicitly saved as OPEN.
D .False. Used for state management, not general mode changes (e.g., OPEN READ WRITE).

NEW QUESTION # 51
In which two ways would you disable timing information collected for wait events and much of the performance monitoring capability of the database?

A. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.LEVEL(BASIC).
B. By setting the TIMED_STATISTICS_LEVEL system parameter to FALSE.
C. By setting the STATISTICS_LEVEL parameter to BASIC.
D. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.DISABLE(TRUE).
E. By setting the TIMED_STATISTICS system parameter to FALSE.

Answer: C,E

Explanation:
A .True. TIMED_STATISTICS = FALSE disables timing data collection.
B .False. No such procedure exists.
C .False. No TIMED_STATISTICS_LEVEL parameter exists.
D .True. STATISTICS_LEVEL = BASIC disables most performance monitoring.
E .False. No such procedure exists.

NEW QUESTION # 52
Which two AWR-based tools listed below are part of Oracle Database self-tuning components?

A. Automatic capture of statistical information from the SGA and storing it in the AWR using Automatic Database Diagnostic.
B. Automatic Diagnostic Collector used to capture and store database errors and hung analysis.
C. Automatic Application Tracing used to collect High-Load SQL statements and statistics.
D. ADDM, a server-based expert that reviews database performance statistics captured by Snapshots to identify potential problems before system performance degrades noticeably.
E. Automatic population of performance views (V$ views) from statistical data stored in AWR repository and using Automatic Database Diagnostic.
F. Automatic Application Tracing used to collect High-Load SQL statements and statistics.

Answer: A,D

Explanation:
False. No "Automatic Application Tracing" exists as an AWR tool. SQL tracing (e.g., DBMS_MONITOR) is manual, and high-load SQL is captured by AWR indirectly via V$SQL snapshots, not a distinct tracing tool.
Why Incorrect:Conflates manual tracing with AWR's passive collection.
Explanation:
The Automatic Workload Repository (AWR) is a cornerstone of Oracle's self-tuning capabilities, collecting and storing performance statistics for analysis. Let's dissect each option:
A : Automatic capture of statistical information from the SGA and storing it in the AWR using Automatic Database Diagnostic.
True. AWR automatically captures statistics (e.g., wait events, SQL stats) from the System Global Area (SGA) via the MMON (Manageability Monitor) process, storing them in the AWR repository (in SYSAUX). This is part of the Automatic Database Diagnostic Monitor (ADDM) framework, though "Automatic Database Diagnostic" likely refers to this broader mechanism.
Mechanics:Snapshots are taken hourly by default (configurable via DBMS_WORKLOAD_REPOSITORY.MODIFY_SNAPSHOT_SETTINGS), persisting data like DBA_HIST_SYSSTAT for self-tuning analysis.
Practical Use:Enables historical performance tracking, feeding tools like ADDM and SQL Tuning Advisor.
Edge Case:If STATISTICS_LEVEL=BASIC, AWR collection is disabled, haltingself-tuning.
Historical Note:Introduced in 10g, enhanced in 23ai for finer granularity.
B : ADDM, a server-based expert that reviews database performance statistics captured by Snapshots to identify potential problems before system performance degrades noticeably.
True. The Automatic Database Diagnostic Monitor (ADDM) analyzes AWR snapshots to proactively detect issues (e.g., high CPU usage, I/O bottlenecks) and recommend fixes. It runs automatically after each snapshot in maintenance windows.
Mechanics:ADDM uses DBA_ADVISOR_FINDINGS to log issues, leveraging AWR data like DBA_HIST_SQLSTAT. Example: It might suggest adding an index for a slow query.
Practical Use:Prevents performance degradation in production systems by catching trends early.
Edge Case:Limited by snapshot frequency; real-time issues may need manual intervention.
C : Automatic Diagnostic Collector used to capture and store database errors and hung analysis.
False. No such tool exists as an "Automatic Diagnostic Collector" in AWR context. This likely confuses the Incident Packaging Service (IPS) or ADR (Automatic Diagnostic Repository), which handles errors but isn't AWR-based or self-tuning.
Why Incorrect:ADR collects trace files and logs, not AWR statistics, and isn't part of self-tuning.
D : Automatic population of performance views (V$ views) from statistical data stored in AWR repository and using Automatic Database Diagnostic.
False. V$ views (e.g., V$SESSION) are real-time memory structures in the SGA, not populated from AWR, which is historical (e.g., DBA_HIST_*). AWR doesn't back-feed V$ views; the reverse occurs via snapshots.
Why Incorrect:Misunderstands the data flow; AWR is a sink, not a source for V$ views.

NEW QUESTION # 53
Which data dictionary view describes the data sources of external tables?

A. DBA_ALL_USER_TABLES
B. DBA_ALL_USER_TAB_COLUMNS
C. DBA_ALL_USER_EXTERNAL_TABLES
D. DBA_ALL_USER_EXTERNAL_LOCATIONS

Answer: D

Explanation:
A .True. DBA_EXTERNAL_LOCATIONS (or prefixed variants) shows external table data sources (e.g., file paths).
B-D .False. These views cover columns or tables but not external sources specifically.

NEW QUESTION # 54
Which two statements describe why Database Auditing is a security requirement?

A. To protect against data corruption.
B. To monitor suspicious activity.
C. To monitor proper usage of the system and data by privileged users.
D. To protect against data theft by a non-authorized user.
E. To alert DBAs about system issues.

Answer: B,C

Explanation:
A .True. Auditing tracks suspicious actions.
B .False. That's monitoring, not auditing.
C .False. Auditing detects, doesn't prevent.
D .False. Corruption is a reliability issue.
E .True. Ensures privileged user compliance.
