Why each option
To provide remote users with access to on-premises Cisco collaboration features via Mobile and Remote Access (MRA), Cisco Expressway-E, Expressway-C, and Cisco Unified Communications Manager (UCM) are the essential components.
Cisco Unified Border Element (CUBE) is for PSTN connectivity, and Cisco Video Communication Server (VCS) is an older product line largely superseded by Expressway for MRA functionality.
CUBE is used for PSTN connectivity, not for MRA, and VCS is an older product line for video communications.
Cisco Expressway-E provides secure external access for remote users, Cisco Expressway-C acts as the internal traversal server and registers with UCM, and Cisco UCM is the core call control platform where endpoints register and collaboration services are hosted, forming the complete MRA solution.
While Cisco IM and Presence Server is a collaboration service, it is not one of the three core architectural components (Expressway-E, Expressway-C, UCM) required to enable MRA itself, and VCS is an older product.
