I can't thank Examstrack enough for their authentic study material. It was a game-changer for my 1z0-497 certification exam.

Questions 2

Which statement regarding Oracle Active Data Guard 12c is false?

Options:

Any application compatible with a read-only database can run on an Oracle Active Data Guard standby.

It provides new support for DML to global temporary tables and the use of sequences in the standby database.

It repairs block corruptions detected in the primary or standby database.

It supports different software patch levels between a primary database and its physical standby database for the purpose of applying and validating Oracle patches in a rolling fashion.

It supports multi master and bidirectional replication architectures where there are multiple databases that all contain the same data, even if they are not synchronized.

Questions 3

Which normalization level is adopted in real-world database systems?

Options:

1NF

2NF

3NF

BCNF

Questions 4

Which three statements about Automatic Database Diagnostic Monitor (ADDM) are true?

Options:

It requires the database to be open.

It analyzes the performance of specified objects.

It implements all recommendations automatically.

It recommends solutions and quantifies expected benefits.

It retains snapshots in the SYSAUX tablespace until the database is restarted.

It analyzes the snapshots stored in the Automatic Workload Repository (AWR).

Questions 5

What happens if you execute these SQL statements?

SQL> show con_name

CON_NAME

--------------------------------

CDB$ROOT

SQL> create user 1_freed identified by y container=current;

Options:

A common user is created in the root container.

A local user is created in the root container.

A local user is created in all the PDBs.

The second SQL statement fails because a local user cannot be created in the root container.

Questions 6

When executing shutdown abort in a pluggable database (PDB), you ____________.

Options:

shut down abort the CDB

shut down abort the PDB

shut down immediate the PDB

shut down immediate the CDB

Questions 7

Which two statements about multitenant architecture are true?

Options:

Multiple PDBs on a single server need multiple database instances and multiple sets of database files.

Although consolidated into a single physical database, PDBs mimic the behavior of non-CDBs.

A PDB administrator can use Oracle Flashback or point-in-time recovery to retrieve lost data from a PDB, only by shutting down all the PDBs from the CDB.

It is easier to collect performance metrics for many databases in a CDB than individual non-CDB databases.

It takes more time to apply a patch to one CDB that holds hundreds of PDBs than to hundreds of non-CDB databases.

Questions 8

You want to clone PDB1 and PDB2 into the same CDB. Which statement is correct?

Options:

You cannot do this, because you can only clone PDBs into another CDB.

You can clone only one PDB (either PDB1 or PDB2) into the same CDB.

Cloning a PDB can use the source files copy method to the target PDB files.

Cloning a PDB can use the NOCOPY clause if the target PDB files use the source files.

Questions 9

Your customer is planning for a maximum-availability architecture at their data center to address their planned downtime, unplanned downtime, and replication needs.

Consider these options:

- Instance, site recovery, and heterogeneous setup

- Inter-region and intra-region load balancing across replicated databases

- Fine-grained error investigation of incorrect results

- Integrated client and application failover

- Fastest and simplest database replication

Which four options would you recommend?

Options:

Oracle GoldenGate

Global Data Services

Oracle Data Guard

Data Recovery Advisor

Oracle Flashback technology

Oracle Advanced Queuing

Questions 10

Which three statements about replication options are true?

Options:

The Oracle Streams information flow consists of three components: capture, redo transfer, arid consumption.

Oracle Streams is deprecated in Oracle Database 12c Release 1.

Oracle Database Advanced Replication is deprecated in Oracle Database 12c Release 1, including multimaster replication, updatable materialized views, multitier materialized views, and deployment templates.

Oracle Database Advanced Queuing is independent of Oracle Streams.

The Oracle GoldenGate software architecture is composed of three primary components: capture, propagate, and trail files.
