Which IBM tool is used to create subscription sets and add subscription set members when configuring data replication?

Introduction / Context:
This question is about DB2 and IBM data replication tooling. When setting up replication, administrators define subscription sets that describe what tables and changes are captured and applied between source and target databases. IBM provides graphical tools that simplify the creation and management of these subscription sets.

Given Data / Assumptions:

The environment uses IBM database products that support replication.

Subscription sets and their members need to be defined.

IBM graphical tools are available to assist with replication configuration.

Only one tool is dedicated specifically to replication tasks.

Concept / Approach:
Replication Center is the IBM tool specifically designed to configure and manage DB2 data replication objects such as subscription sets, subscription members, and replication sources. Other tools, such as Development Center and License Center, have different purposes. Journal is a generic term that does not refer to the graphical replication configuration utility.

Step-by-Step Solution:
1. Identify which options are actual DB2 tools and which are generic names. 2. Recall that Replication Center provides user interfaces for creating and editing subscription sets. 3. Understand that License Center manages product licenses, not replication metadata. 4. Recognize that Development Center is aimed at application development tasks like stored procedures. 5. Conclude that Replication Center is the correct tool for creating subscription sets and their members.

Verification / Alternative check:
IBM documentation for DB2 Data Propagator and later replication components references Replication Center as the primary interface for configuring replication environments and subscription sets.

Why Other Options Are Wrong:
Journal is not the name of a DB2 GUI tool in this context and does not describe replication configuration software.
License Center is used for license management and activation, not for defining replication objects.
Development Center focuses on development tasks and does not include full replication configuration capabilities.

Common Pitfalls:
Learners sometimes assume that any tool with a general sounding name could handle replication. It is important to remember the specific roles of IBM tools. Replication environments often involve many components, so using the dedicated Replication Center interface reduces configuration errors.

Final Answer:
The correct tool is Replication Center.
