Configuration Management

Correct Answer: A clear baseline identification scheme

A clear baseline identification scheme is the most essential component to establish first in a version control repository because: It provides the fundamental structure for: - Identifying and labeling different versions of project artifacts - Creating a stable reference point for all future changes - Enabling effective tracking of modifications from a known starting point - Facilitating proper version comparisons and rollbacks While tracking changes, user permissions, and workflow processes are important, they are secondary considerations that build upon a proper baseline scheme. Tracking historical changes is valuable but requires a baseline to be meaningful. Documentation of access permissions is a security consideration that comes after establishing basic version control structure. Branching and merging workflows are advanced features that rely on having a solid baseline identification system in place first.

Correct Answer: To track the history of changes made to configuration items over time

The primary purpose of a Configuration Control Log is to track and document changes made to configuration items throughout their lifecycle. This historical record is essential for: - Understanding what changes were made - When changes occurred - Who authorized the changes - The reasons behind the modifications - Maintaining traceability and accountability This tracking helps in auditing, troubleshooting, and ensuring proper version control of configuration items. The other options are incorrect because: Meeting records and discussions are typically documented in meeting minutes or project communication logs, not in the Configuration Control Log. Roles and responsibilities documentation belongs in organizational process assets or project management plans. Establishing process flows for future changes is part of process improvement activities and lessons learned documentation, not the primary purpose of a Configuration Control Log.

Correct Answer: Ripple Effect: Changes in one component can trigger necessary updates in dependent components

The Ripple Effect is the most accurate principle describing cascading changes in configuration management where components share dependencies. This concept accurately describes how modifications in one component can necessitate changes in other dependent components, creating a chain reaction of updates. It reflects the real-world scenario where interconnected system elements require coordinated updates due to their relationships. The alternative answers are incorrect because: - Change Propagation suggests all components must update simultaneously, which is not always necessary or practical in real systems. - Sequential Modification implies a rigid, predetermined path of changes, which does not reflect the complex web of dependencies that may exist. - Dependency Chain incorrectly suggests that every change requires complete system reconfiguration, which is excessive and inefficient for most changes.
