UDM stands for Unit Deployment Manager.

• A. Unified Deployment Monitor.
• B. Unit Deployment Master.
• C. Unit Delivery Manager.
• D. Unit Deployment Manager.

Answer: (D)

Acronyms in deployment contexts are built from clear, role-based words. UDM combines Unit, Deployment, and Manager, which points to a role or system that coordinates how a unit moves into an operation—planning, scheduling, and tracking the deployment of personnel and equipment. That exact meaning fits best with Unit Deployment Manager, because it describes the entity responsible for managing the deployment process. The other phrasings shift the emphasis to monitoring, mastering, or delivering, which do not align with the standard function implied by UDM. So the expansion Unit Deployment Manager is the most accurate.
