Oracle 1Z0-182 Sample Questions:

01. During a design discussion, a colleague asks what an embedding actually captures about a piece of text or an image.
What does a vector embedding represent?
a) A compressed backup copy of the item's source row
b) The item's meaning encoded as an array of numbers
c) The physical block address of the stored value
d) A one-way hash value generated to enforce a uniqueness constraint
 
02. Most services register with the listener dynamically, but a DBA is identifying situations that call for static service registration in the listener configuration file.
Which two situations are valid reasons to configure a static registration entry?
(Choose two.)
a) To remove the need to ever start the listener.
b) To allow a management tool to start the instance remotely while it is down.
c) To support a tool that expects the service to be listed even when the instance is not registered.
d) To let the instance register its services automatically at startup.
e) To make routine client connections faster during normal operation.
 
03. Performance was poor during last night's batch window. The DBA wants an automated analysis that names the top root-cause findings for that period and recommends corrective actions, without manually reading raw statistics.
Which approach best meets this need?
a) Query dynamic performance (V$) views to inspect current session activity.
b) Create a SQL Plan Baseline so the optimizer reports the slow statements.
c) Review the ADDM analysis for that period, which reports top findings and recommends actions.
d) Generate an AWR report for the interval and manually read through the raw statistics to locate the root cause.
 
04. User A grants a table's SELECT object privilege to user B with the grant option, and user B then grants the same privilege to user C. User A later revokes the privilege from user B.
What happens to user C's access?
a) User C also loses the privilege, because object-privilege grants cascade on revoke
b) The revoke fails until user C's privilege is revoked first
c) User C keeps the privilege, because each object-privilege grant is independent once made
d) User C keeps the privilege until user B's account is dropped
 
05. Which memory structure temporarily holds the change vectors (redo entries) that describe modifications to the database before they are written to disk?
a) The database buffer cache
b) The large pool
c) The shared pool
d) The redo log buffer
 
06. A DBA must run the Database Configuration Assistant where a graphical display is available on one server but the operation has to be automated on many others.
Which two ways can DBCA be invoked to create a database?
(Choose two.)
a) By editing the control file directly to register a new database.
b) In interactive mode through its graphical wizard.
c) By running Oracle Universal Installer with a create-database flag.
d) By issuing a listener control command that provisions a database.
e) In silent mode driven by a response file.
 
07. Immediately after installing the Oracle Database software on a new server, a DBA performs required steps before creating a database.
Which two are legitimate post-installation configuration activities?
(Choose two.)
a) Issuing a media-recovery command to open the freshly installed binaries.
b) Running the configuration scripts the installer prompts to execute with elevated privileges.
c) Loading production data with a direct-path load before the database exists.
d) Dropping the SYSTEM tablespace to reclaim installation disk space.
e) Configuring a listener so that clients can connect to databases on the server.
 
08. On a standalone server, Oracle Restart is configured and a DBA administers its resources with srvctl.
Which three component types can be registered with and managed by Oracle Restart?
(Choose three.)
a) A single SQL execution plan.
b) The database instance.
c) An individual user's schema objects.
d) The Oracle Net listener.
e) A tablespace's undo retention setting.
f) An Oracle ASM instance.
 
09. To follow separation of duties, a DBA wants a dedicated administrator who can manage the TDE keystore and encryption keys without holding full SYSDBA control of the database.
Which approach best fits this goal?
a) Grant SYSDBA, since key management requires full administrative control
b) Grant the DBA role, which is assumed to include keystore administration
c) Grant a profile that permits keystore operations
d) Grant the administrative privilege dedicated to key management
 
10. When a pluggable database is unplugged from its container database, Oracle produces a descriptor that another CDB later uses to plug it in.
What does this descriptor contain?
a) The common users and roles from the root container.
b) A complete copy of all the PDB's data blocks stored inside the descriptor file.
c) Metadata describing the PDB and the location of its datafiles.
d) The redo generated by the PDB since it was created.
