Oracle 1Z0-447 Sample Questions:

01. Before capturing from an Oracle source, which preparation enables the row-level change information GoldenGate needs?
a) Run DEFGEN on the source before any logging is enabled.
b) Enable supplemental logging, including table-level logging via ADD TRANDATA.
c) Disable ARCHIVELOG to reduce log volume.
d) Create database triggers on each source table.
 
02. What is the difference between GLOBALS parameters and MANAGER parameters?
a) GLOBALS control only Extract; MANAGER parameters control only Replicat.
b) GLOBALS configure the network ports; MANAGER sets the checkpoint schema.
c) They are interchangeable and can be placed in either file.
d) GLOBALS are instance-wide; MANAGER parameters control the Manager.
 
03. How does 'real-time data integration' extend beyond basic DML replication in GoldenGate?
a) It replaces log-based capture with scheduled batch extracts.
b) It adds transformation and delivery to targets beyond a raw apply of captured DML.
c) It requires triggers on the target to reformat each row.
d) It stops replicating DML and only replicates DDL changes.
 
04. When a record matching a condition is processed, the run must write a log entry and then stop the process.
Which mechanism configures this behavior?
a) FILTER with EVENTACTIONS, specifying actions such as LOG and ABORT.
b) The checkpoint table with an action trigger.
c) COLMAP with an action clause.
d) ENCRYPTTRAIL with an on-match handler.
 
05. A heterogeneous replication applies wrong values into some target columns, and the structures differ between source and target.
What is the most likely configuration cause to check first?
a) The database is in ARCHIVELOG mode on the source.
b) Trail encryption with ENCRYPTTRAIL is enabled.
c) A missing or stale SOURCEDEFS definitions file for the differing structures.
d) Veridata has not been scheduled to run.
 
06. Data at rest in the trail files must be protected.
Which GoldenGate capability addresses this?
a) Trail encryption via ENCRYPTTRAIL, using a master-key wallet.
b) The checkpoint table, which stores encrypted positions.
c) The COLMAP parameter, which scrambles columns.
d) The DYNAMICPORTLIST parameter, which secures ports.
 
07. On the target host, which process physically receives the data sent across the network and writes the remote trail?
a) The primary Extract, which writes the remote trail after mining the target logs.
b) The Data Pump on the target, which writes and then reads its own trail.
c) The Collector, started dynamically by Manager, writes the remote trail on the target.
d) Replicat, which writes the remote trail before applying it.
 
08. Two data centers must both accept writes to the same tables and stay synchronized with each other.
Which GoldenGate topology fits this requirement?
a) Broadcast replication from one source to many targets.
b) A unidirectional feed from one site to the other.
c) Consolidation replication from many sources to one target.
d) Bidirectional (active-active) replication between the two systems.
 
09. Within COLMAP, what does USEDEFAULTS do?
a) Encrypts any column whose mapping is left unspecified.
b) Sets default trail file names for the process.
c) Automatically maps source and target columns that share the same name and compatible type.
d) Filters out rows that do not match a default condition.
 
10. Source and target tables have identical structures.
Which table-definition parameter is appropriate, and why?
a) PURGEOLDEXTRACTS, because it aligns the definitions.
b) SOURCEDEFS, because it is always required for Replicat.
c) EXTTRAIL, because it declares the source structure.
d) ASSUMETARGETDEFS, since the target matches the source.
