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 # 51

Examine this output: Which two are true? (Choose two.)

Any PDB not specified in the plan will be unable to execute statements in parallel.

PDB3 can use all available parallel execution processes at times.

PDB1 is always limited to 40% of the available system resources regardless of demand.

Any PDB notspecified in the plan will be able to use a maximum of 16.5% of the available system resources.

PDB3 is guaranteed to receive at least 20% of the available system resources if there is enough demand.

PDB2 is guaranteed at least 25% of the available parallel execution processes if there is enough demand.

Question # 52

choose three You want to duplicate one of your databases when connected to the target database and to the recovery catalog. Which three are true about this type of database duplication ) The duplication process can create backup sets or image copies

The target database must be open

The duplication process can use existing backup sets or image copies

The duplication process can use existing backup sets or image copies.

The target database must be in mount state.

The duplication -process pushes backup sets to the auxiliary instance.

The duplication process pushes image copies to the auxiliary instance.

Question # 53

Choose three. Which three are true about interpreting Recovery Manager (RMAN) error stacks returned to standard output?

If an RMAN command fails, the output will only identify the command that failed.

Some messages in the error stack are not errors.

If an RMAN command fails, the output will identify the channel ID where the failure occurred. D)Media Management errors appear as a line with " Additional information " and a number.

Media Management errors appear as a line with " sbtio " and a number.

Media Management errors appear as a line with " sbtio " .

Question # 54

For which two requirements can you use the USER_TABLESPACE clause with the CREATE PLUGGABLE DATABASE command? (Choose two.)

to specify a default tablespace in a PDB cloned from another PDB in the same CDB

to exclude all tablespaces except SYSTEM, SYSAUX, and TEMP when plugging in a PDB

to include specific user tablespaces only when relocating a PDB

to specify the list of user tablespaces to include when moving a non-CDB to a PDB

to exclude a temp tablespace when plugging in a PDB

to specify the list of tablespaces to include when creating a PDB from the CDB seed

Question # 55

Choose three. Which three are true about Data Pump in an Oracle multitenant environment?

It can be used to transport data from a non-CDB to a PDB.

It can be used to clone a CDB.

It can be used to transport data between PDBs.

It can be used to transport data from a PDB to a non-CDB.

It can be used to create a new PDB.

Question # 56

In your Database, the TBS PERCENT USED parameter is set to 60 and the TBS PERCENT FREE parameter is set to 20. Which two storage-tiering actions might be automated when using information Lifecycle Management (ILM) to automate data movement?

The movement of all segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED

Settingthetargettablespacetoread-only

The movement of some segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED

Setting the target tablespace offline

The movement of some blocks to a target tablespace with a lower degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED Correct

Question # 57

Choose the best answer. Which should be tuned first when doing a performance tuning exercise for an Oracle Database environment?

log writer performance

database writer performance

general operating system health

SQL statements

database instance memory management and sizes

Question # 58

Choose the best answer. Which operating system group is NOT needed to perform an Oracle Database installation?

OSASM

OSRACDBA

OSKMDBA

OSDBA

E ） OSOPER

Question # 59

Identify three scenarios in which RMAN will use backup sets to perform active database duplication.

when the duplicate ... from active database command contains the section size clause

when you perform active database duplication on a database with flashback disabled

when you specify set encryption before the duplicate ... from active database command

when the number of auxiliary channels allocated is equal to or greater than the number of target channels

when you perform active database duplication on a database that has readonly tablespaces

Question # 60

Choose three. PDB1 and PDB2 are pluggable databases in CDB1. Examine these commands: $ export ORACLE_SID=CDB1 $ sqlplus / as sysdba SQL > STARTUP ....... Database opened. SQL > SHOW PDBS CON_ID CON_NAME --------------------------------------------------------------------OPEN MODE READ ONLY NO MOUNTED MOUNTED SQL > ALTER PLUGGABLE Pluggable database altered. SQL > ALTER PLUGGABLE DATABASE pdb1 SAVE STATE; Pluggable database altered. SQL > ALTER PLUGGABLE DATABASE pdb1 CLOSE; Pluggable database altered.
