Details for 1Z0-062

Particularly, 1Z0-062 certification test contains a total of about 67 multiple-choice questions that the students have to complete within 2 hours. If you want to pass this exam, you should try to get more than 64% of the correct answers. This Oracle test will cost you $245 and to ace it with flying colors, you should explore its topics first. Thus, here are a few of them:

Introduction to DBAAS.
Oracle network environment configuration;
User security administration;
Concepts of recovery and backup;
Developing and managing tablespaces;
Database storage structures and undo data management;
Oracle database architecture and management tools;

The procedure of earning this associate-level Oracle Database certificate expands by all odds the boundaries of candidates’ knowledge and applied experience, allowing them to accomplish complicated practical lab tasks on the final test, and then in practice on a daily basis. Meanwhile, Oracle certification tests reveal your potential and measure as well as challenge your capability to reason and act through real questions based on varied scenarios.

NO.30 You are connected using SQL* Plus to a multitenant container database (CDB) with SYSDBA privileges and execute the following sequence statements:

What is the result of the last SET CONTAINER statement and why is it so?

It succeeds because the PDB_ADMIN user has the required privileges.

It fails because common users are unable to use the SET CONTAINER statement.

It fails because local users are unable to use the SET CONTAINER statement.

If fails because the SET CONTAINER statement cannot be used with PDB$SEED as the target pluggable database (PDB).

NO.31 You run a script that completes successfully using SQL*Plus that performs these actions:
1. Creates a multitenant container database (CDB)
2. Plugs in three pluggable databases (PDBs)

The value of the MEMORY_MAX_TARGET parameter remains zero for the database instance.

The lower limits of the PGA_AGGREGATE_TARGET and SGA_TARGET parameters are set to 90 MB and 270 MB respectively.

The instance does not start up because Automatic Memory Management (AMM) is enabled but PGA_AGGREGATE_TARGET and SGA_TARGET parameters are set to nonzero values.

NO.33 Which three statements are true about a job chain?

It can contain a nested chain of jobs.

It can be used to implement dependency-based scheduling.

(Choose two.)

Both the indexes are created; however, only the ORD_COSTOMER index is visible.

The optimizer evaluates index access from both the Indexes before deciding on which index to use for query execution plan.

Only the ORD_CUSTOMER_IX1 index is created.

Only the ORD_CUSTOMER_IX2 index is created.

Both the indexes are updated when a new row is inserted, updated, or deleted In the orders table.

NO.35 After implementing full Oracle Data Redaction, you change the default value for the NUMBER data type as follows:

After changing the value, you notice that FULL redaction continues to redact numeric data with zero.

Re-create redaction policies that use FULL data redaction.

Re-connect the sessions that access objects with redaction policies defined on them.

Flush the shared pool.

Restart the database instance.

NO.36 Which two statements are true about the Automatic Database Diagnostic Monitor (ADDM)?
(Choose two.)

The ADDM requires at least four AWR snapshots for analysis

The ADDM runs after each AWR snapshot is collected automatically by MMON

The results of the ADDM analysis are stored in the Automatic Workload Repository (AWR)

The ADDM analysis provides only diagnostics information but does not provide recommendations

The ADDM calls other advisors if required, but does not provide recommendations about the advisors

NO.37 Examine the resources consumed by a database instance whose current Resource Manager plan is displayed.
SQL> SELECT name, active_sessions, queue_length,
Consumed_cpu_time, cpu_waits, cpu_wait_time
FROM v$rsrc_consumer_group;
NAMEACTIVE_SESSIONS QUEUE_LENGTH CONSUMED_CPU_WAITS

The CPU_WAIT_TIME column indicates the total time that sessions in the consumer group waited for the CPU due
to resource management.

The CPU_WAIT_TIME column indicates the total time that sessions in the consumer group waited for the CPU due
to I/O waits and latch or enqueue contention.

A user belonging to the DSS__QUERIES resource consumer group can create a new session but the session will be
