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.

It is a set of recommendations by the optimizer to change the access methods used.

It is auxiliary information collected by the optimizer for a SQL statement to eliminate estimation error.

It is a set of recommendations by the optimizer to restructure a SQL statement to avoid suboptimal execution plans.

It is auxiliary information collected by the optimizer for a SQL statement to help use better joins orders.

Question # 63

Which four are true about RMAN backup sets? (Choose four.)

A backup piece can belong to only one backup set.

A data file can be split into multiple sections stored in different backup sets.

Blocks from multiple data files can be contained in one backup piece,

A backup set can contain only one backup piece.

Question # 64

RMAN is connected to the target database prod1 and an auxiliary instance in nomount state. Examine the command to create a duplicate database: RMAN > DUPLICATE TARGET DATABASE TO dup1 FROM ACTIVE DATABASE NOFILENAMECHECK PASSWORD FILE SPFILE; Which two statements are true about the execution of the duplicate command?

All archive redo log files are automatically copied to the duplicate database.

The duplicate database has the same directory structure as the source database.

The duplicate database is created by using the backups created during the execution of

he duplicate command.

The password file and SPFILE for the duplicate database dup1 are created in their respective default locations.

The duplicate database is created without using RMAN backups and prod1 is allowed to remain open during duplication.

Question # 65

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

Data Recovery Advisor can proactively check for failures.

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

ata Recovery Advisor can be used if a database is in the NOMOUNT state.

A failure can be closed only if the database is in MOUNT state.

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

Question # 66

What is the effect of specifying the " ENABLE PLUGGABLE DATABASE " clause in a " CREATE DATABASE " statement?

It will create a multitenant container database (CDB) with only the root opened.

ItwillcreateaCDBwithrootopenedandseedreadonly.

It will create a CDB with root and seed opened and one PDB mounted.

It will create a CDB that must be plugged into an existing CDB.

ItwillcreateaCDBwithrootopenedandseedmounted.

It offers fine-grained analysis of all the SQL statements in the analysis task as a group.

SQL statements that were originally run concurrently are run concurrently by SPA.
