解説：
User exits don't work in passthru mode (no transformation).

質問 # 57
You can create a macro library that contains one or more macros. By using a macro library, you can define a macro once and use it again and again. What is true about macro libraries?

A. You can share the macros across parameter files.
B. If a macro is defined in a macro library, you may only call that macro once in a parameter file.
C. You can either have the Extract or the Replicat in the same GoldenGate Home invoke the macros in the library but not from with both Extract and Replicat.
D. You can invoke the macros in a library only one time in COLMAP in the Replicat parameter file.

正解：A

解説：
Macro libraries in Oracle GoldenGate allow you to define reusable macros and share them across multiple parameter files, improving consistency and reducing duplication in Extract and Replicat configurations.

質問 # 58
You have an issue where all threads are waiting for a specific transaction to be executed first. What is this issue related to?

A. It is caused by THREAD and THREADRANGE being used with wildcard MAP statements.
B. It is caused by the use of the MAXTRANSOPS parameter.
C. It is caused by the thread with the highest thread ID applying barrier transactions.
D. It is caused by barrier transactions in a Coordinated Replicat.

正解：D

解説：
In Coordinated Replicat, a barrier transaction is a transaction that must be applied in commit order, causing all threads to pause until that transaction is completed - leading to the situation where all threads wait for one.

Full DBA role is not mandatory for Extract or Replicat.

質問 # 65
What is implemented by Oracle GoldenGate to be able to obtain trail files from the source when the source Distribution Server cannot initiate communication with the target where the Receiver Server is?

A. A secured port must be implemented and opened by the target to enable the source Distribution Server to be able to initiate communication with the target's Receiver Server.
B. The Extract will directly send trail files for the Replicat to receive and apply changes.
C. Microservices Architecture Authentication will initiate communication for the Distribution Server.
D. A Receiver Server can pull trail files from Distribution Server using a single port for Reverse proxy.

正解：D

解説：
In Oracle GoldenGate Microservices Architecture, when the source Distribution Server cannot initiate outbound communication (e.g., due to firewall or network restrictions), the Receiver Server on the target can be configured to pull trail files using Reverse Proxy mode - establishing a single, secure inbound connection.

質問 # 66
You have offloaded data from the source onto a file. What method would you use to perform your initial load onto the target database?

A. GoldenGate Direct Load
B. File to Replicat
C. File to database utility
D. Direct bulk load to SQL*Loader

Oracle GoldenGate Software Command Interpreter (text-based interface)

質問 # 69
Add TranData enables supplemental logging of key values in the transaction logs whenever a row change occurs.

A. FALSE
B. TRUE

正解：B

解説：
ADD TRANDATA logs key changes needed for replication.

質問 # 70
How is Integrated Capture different from Classic Capture?

A. Integrated Capture is different because it receives Logical Change Records (LCRs) directly from a database logmining server.
B. Integrated Capture is different because it automatically configures the Capture process of GoldenGate.
C. Integrated Capture is different because it connects directly to the inbound server to apply transactions.
D. Integrated Capture is different because it captures processes to integrate with an application server.

正解：A

解説：
The main difference between Integrated and Classic Capture in Oracle GoldenGate lies in how changes are captured from the database. Integrated Capture uses a database logmining server to receive Logical Change Records (LCRs) directly, while Classic Capture directly reads redo log files.

質問 # 71
You need to manually patch Oracle GoldenGate source and targets. How should you proceed?

A. Stop access to the source and target databases. Start applying the patch on the source. Stop the data pump and Replicat. Apply the patch on the target. Start the Oracle GoldenGate processes whenever you are ready to begin capturing user activity again.
B. Stop access to the source and target databases. Allow Extract to finish capturing the transaction data that remains in the transaction log and stop Extract. Start applying the patch on the source. Wait until the data pump (if used) and Replicat are finished processing the data in their respective trails. Stop the data pump and Replicat. Apply the patch on the target. Start the Oracle GoldenGate processes whenever you are ready to begin capturing user activity again.
C. Stop access to the source database. Allow Extract to finish capturing the transaction data that remains in the transaction log and stop Extract. Start applying the patch on the source and on the target. Start the Oracle GoldenGate processes whenever you are ready to begin capturing user activity again.
D. Stop access to the source. Allow Extract to finish capturing the transaction data that remains in the transaction log and stop Extract. Start applying the patch on the source. Wait until the data pump/Replicat are finished processing the data in their respective trails. Stop the data pump/Replicat. Apply the patch on the target. If the patches changed table defs, run DEFGEN for the source tables to generate updated source defs, and then replace the old defs with the new ones in the existing source defs file on the target. Start GG processes when ready to begin capturing activity again.

正解：D

解説：
This is the only option that:
* Waits for Extract to finish capturing remaining redo/transaction log data ✅
* Waits for Data Pump and Replicat to reach EOF ✅
* Properly stops components in sequence ✅
* Accounts for definition file updates (DEFGEN) if metadata changes ✅

質問 # 72
If multiple GoldenGate processes are accessing a set of trail files, which process should include the PURGEOLDEXTRACTS parameter to trigger trail file clean-up?

A. Manager
B. Extract
C. Replicat
D. Extract and Replicat

正解：A

解説：
The PURGEOLDEXTRACTS parameter should be configured in the Manager (MGR) process, as it is responsible for monitoring trail file usage across GoldenGate processes and safely deleting files no longer needed by any Extract or Replicat.

質問 # 73
You must synchronize the starting point for Replicat with the restore point of the target database. How should you accomplish this?

A. Use the command option ATCSN.
B. Use the command option UNTIL CANCEL.
C. Use the command option RESUME.
D. Use the command option AFTERCSN.

正解：D

解説：
"AFTERCSN causes Replicat to start processing at the transaction that occurred after the one with the specified CSN. Any transactions in the trail that have CSN values that are less than, or equal to, the specified one are skipped."

質問 # 74
You are concerned that the process report generation in your production environment will become too large and not contain useful statistics.

A. GoldenGate automatically generates a new report when the processes start.
B. Use the parameter REPORT.
C. Use the parameter REPORTROLLOVER.
D. Use the ADD EXTTRAIL command option MEGABYTES.

正解：C

解説：
The REPORTROLLOVER parameter lets you automatically rotate and archive GoldenGate process report files based on size, time, or process restarts, preventing them from growing too large and cluttering with old data.

質問 # 75
An Oracle GoldenGate topology is a representation of the databases in a GoldenGate environment, how the GoldenGate components are configured on each server, and the flow of data between the components. What topology describes a configuration of data flow from one source site to many target sites?

A. Multimaster
B. Cascading
C. Integration
D. Broadcast

正解：D

解説：
Broadcast topology describes a one-to-many data replication model: A single source sends data to multiple target sites Targets often receive the same set of replicated changes
