Oracle Database Administration II

Engineering Data Sovereignty: Why Deep Database Architecture Triumphs Over Obsolete Dumps

We have coached hundreds of production DBAs, enterprise data architects, and infrastructure managers through this final, high-stakes milestone of the Oracle Database administration track. Let's look honestly at the modern enterprise environment scaling landscape. The database professionals who stumble on this intensive practical validation are almost always those who leaned heavily on low-tier, linear practice pools—those flat, context-stripped answer repositories floating around unverified technology forums. Those static, unverified materials simply cannot prepare you for live, multi-tenant container management or the intricate backup recovery workflows tested on the real exam. Candidates frequently get stuck searching for high-yield 1Z0-083 exam questions online, trying to source realistic Oracle Database Administration II practice tests to measure their operational skills, or hunting for an updated 1Z0-083 study guide that breaks down multi-section RMAN execution syntax. They quickly realize that memorizing static text strings fails completely when faced with scenario-based component debugging and real-world system emergencies.

At Exact2Pass, our approach targets the underlying structural logic, PL/SQL runtime parameters, and lifecycle governance of the active Oracle 19c container ecosystem instead. Our premium preparation platform delivers comprehensive programmatic breakdowns for every pluggable database cloning activity and cluster upgrade phase. You will master actual production-grade core mechanics instead of leaning on short-sighted memorization shortcuts. We map out Container Database (CDB) and Pluggable Database (PDB) resource profiles, automated AWR snapshots, RMAN media manager (SBT) storage configurations, and Grid Infrastructure standalone homes step by step. Our learning material is designed from the ground up by active, certified principal DBAs who manage multi-terabyte transactional arrays daily. Because of that, we completely avoid mindless, repetitive question-and-answer lists. Instead, our workspace functions as an active infrastructure simulation that forces you to evaluate session states, troubleshoot corrupted blocks, and tune SQL Access Advisor parameters like a master data engineer. You will learn the exact reason why a specific tablespace transport methodology or flashback sequence succeeds or drops fatal runtime exceptions. That is how you build real confidence before logging into your official Oracle MyLearn account or launching your Pearson VUE proctored exam workspace. Our adaptive training software develops deep operational skills that transfer perfectly to production tenants, helping you pass on your very first try.

Question # 41

choose two Which two are benefits of unified auditing in full mode?

All audit data is written to both the traditional locations and to the unified location.

The audit trail is in a single format.

Pre 12c audit data is written to the traditional locations and new 12c audit data is written to the unified location.

The audit trail is read-only.

The audit trail uses less space.

Question # 42

Choose three. Which three are true about upgrading an application in an application container?

An application root clone gets created automatically.

The upgrade can be performed when connected either to CDB$ROOT or to PDB$SEED.

After an application upgrade, the application container ' s PDBs remain synchronized with the existing application root.

The upgrade must be performed when connected to CDB$ROOT.

An application name and version number must be specified to upgrade the application.

After an application upgrade, the application container ' s PDBs are automatically synchronized with the application root clone.

Question # 43

Which three tasks can be automatically performed by the Automatic Data Optimization feature of Information lifecycle Management (ILM)?

Tracking the most recent read time for a table segment in a user tablespace

Tracking the most recent write time for a table segment in a user tablespace

Tracking insert time by row for table rows

Tracking the most recent write time for a table block

Tracking the most recent read time for a table segment in the SYSTEM tablespace

Tracking the most recent write time for a table segment in the SYSAUX tablespace Correct

Question # 44

You execute the following piece of code with appropriate privileges: BEGIN DBMS_REDACT.ADD_POLICY ( END; object_schema object_name column_name policy_name function_type expression = > ' SCOTT ' , = > ' EMP ' , = > ' SAL ' , = > ' SCOTT_EMP ' , = > DBMS_REDACT.FULL, = > ' SYS_CONTEXT ( ' ' SYS_SESSION_ROLES ' ' , ' ' MGR ' ' ) = ' ' FALSE ' ' ' ); END; BEGIN DBMS_REDACT.ADD_POLICY ( object_schema object_name column_name policy_name function_type expression = > ' SCOTT ' , = > ' EMP_VW ' , = > ' SAL ' , = > ' SCOTT_EMP_VW ' , = > DBMS_REDACT.NONE, = > ' SYS_CONTEXT ( ' ' SYS_SESSION_ROLES ' ' , ' ' MGR ' ' ) = ' ' FALSE ' ' ' ); User SCOTT has been granted the CREATE SESSION privilege and the MGR role. Which two statements are true when a session logged in as SCOTT queries the SAL column in the view and the table?

DataisredactedfortheEMP.SALcolumnonlyiftheSCOTTsessiondoesnothavetheMGR role set.

DataisredactedforEMP.SALcolumnonlyiftheSCOTTsessionhastheMGRroleset.

Data is never redacted for the EMP_VW.SAL column.

Data is redacted for the EMP_V.SAL column only if the SCOTT session has the MGR role set.

Data is redacted for the EMP_V.SAL column only if the SCOTT session does not have the MGR role set. Correct

Question # 45

Which two are true about diagnosing Oracle Database failure situations using Data Recovery Advisor? (Choose two.)

Using the Data Recovery Advisor LIST FAILURE command always requires that the database for which failures are to be listed is in MOUNT state.

A failure can be closed only when it has been repaired.

Data Recovery Advisor can be used if a database is closed.

The Data Recovery Advisor CHANGE FAILURE command can be used only to change failure priorities.

Data Recovery Advisor can proactively check for failures.

Question # 46

Choose two. Which two are true about backup set compression using RMAN default compression?

Compressed backups cannot have a section size defined.

Compressed backups can be written only to media.

Binary compression adds CPU overhead to backup operations.

Unused blocks below the high water mark are backed up.

Compression can be done only for locally managed tablespaces.

Question # 47

While backing up to the Oracle Fast Recovery Area (FRA), you determined the backup istaking too long and suspect a performance bottleneck. Which three are true about diagnosing and tuning these problems? (Choose three.)

If an RMAN BACKUP VALIDATE command takesroughly the same time as an actual backup, then both read and write I/O are likely bottlenecks.

Setting DBWR_IO_SLAVES to a non zero value can improve backup performance when using synchronous I/O.

If an RMAN BACKUP VALIDATE command takes noticeably lessthan an actual backup, then write I/O is a likely bottleneck.

If an RMAN BACKUP VALIDATE command takesroughly the same time as an actual backup, then read I/O is a likely bottleneck.

Data files with a high value in V$BACKUP_SYNC_IO.DISCRETE_BYTES_PER_SECOND are a potential performance bottleneck when synchronous I/O is used.

Setting DBWR_IO_SLAVES to a non zero value can improve backup performance when using asynchronous I/O/

Data files with a high value in V$BACKUP_ASYNC_IO.SHORT_WAITS are a potential performance bottleneck when asynchronous I/O is used.

Question # 48

Which three are true about transporting databases across platforms using Recovery Manager (RMAN) image copies? (Choose three.)

By default, the transported database will use Oracle Managed Files (OMF)

Data files can be converted on the destination system.

Data files can be converted on the source system.

A new DBID is automatically created for the transported database.

Databases can be transported between systems with different endian formats.

The password file is automatically converted by RMAN.

Question # 49

.Examine the RMAN command: RMAN > CONFIGURE ENCRYPTION FOR DATABASE ON; RMAN > BACKUP DATABASE PLUS ARCHIVELOG; Which prerequisite must be met before accomplishing the backup?

Oracle wallet for the encryption must be set up.

All the tablespaces in the database must be encrypted

Oracle Database Vault must be enabled.
