Oracle Database 12cR2 Administration is an official Oracle certification exam, listed under the code 1z1-072. Clearing it earns the Oracle Database Administrator (Oracle Database 12c) certification, a Associate-level credential. It also ties into Oracle Database Administrator Certified Associate (OCA), Oracle Database 12c Administrator Certified Professional (OCP), which makes it a useful anchor for a longer certification plan. For employers, the value is simple: the vendor itself has verified what you know.
You will work through 70–80 questions in 120 minutes on the Oracle Database 12cR2 Administration exam. The content is only half the battle; the clock is the other half. Train both at once: set the ValidDumps test engine to full timed mode, practice skipping and returning to stubborn items, and repeat until finishing with minutes to spare feels normal rather than lucky.
Passing Oracle Database 12cR2 Administration requires ~65%, and the official registration fee is $245 USD (may vary by region). Remember that a retake bills the same $245 USD (may vary by region) all over again, so winging it is the most expensive strategy on the table. A better approach: benchmark yourself with the ValidDumps practice tests first, and schedule the real exam only once your scores sit comfortably and consistently above the requirement.
Basic knowledge of Oracle Database administration and SQL recommended. No strict official prerequisite, but foundational SQL knowledge is expected.
Requirements do evolve, so before you spend a registration fee, verify the current conditions on the official exam page.

DATADIR1 and DATADIR2 are database directory objects.
Examine this command:
[oracle@host01 ~] expdp system/oracle \
> FULL=y \
> DUMPFILE=datadir1:full%U.dmp, datadir2: full2%U.dmp \
> FILESIZE=2G \
> PARALLEL=4 \
> LOGFILE= datadir1:/expfull.log
> JOB_NAME= expfull
Which two are true about the expdp operation? (Choose two.)
Examine this extract from the show parameters command:
How are SGA and PGA memory managed by an instance using these parameter settings?
The ORCL database has DEFERRED_SEGMENT_CREATION set to TRUE.
UNDOTBS2 is the active undo tablespace.
Examine these commands:
USER1 executes DML, which generates more than 2 MB of UNDO.
What is the result and why?
The SCOTT/TIGER user exists in two databases, BOSTON_DB and DALLAS_DB, in two different locations.
Each database has a tnsnames.ora file defining DALLAS_DB as a service name.
Examine this command:
CREATE DATABASE LINK dblink1 CONNECT TO scott IDENTIFIED BY tiger USING 'dallas_db'; How do you execute the command so that only SCOTT in BOSTON_DB can access the SCOTT schema in DALLAS_DB?
You want to use table compression suitable for OLTP that will:
1. Compress rows for all DML statements on that table
2. Minimize the overheads associated with compression.
Which compression option is best suited for this?
