Standard Edition Supports a maximum of 10,000 device management, 10,000 number allocation and registration, and 1000 concurrent conference ports. SMC standard edition has a co-deployed SC by default.

Technical Deep Dive

A DMZ is a security network segment separating externally accessible services from trusted internal systems. Huawei CloudVC uses Switch Center for H.323/SIP registration and call control as well as public/private network traversal. A DMZ proxy SC can provide a controlled boundary for Internet-connected endpoints, while an internal SC and SMC remain inside the trusted network. The V2.0 SCT guidance says a proxy SC may be configured in a DMZ according to the customer's network.

If the customer does not already operate a DMZ, a non-DMZ deployment may be considered where the topology and security policies permit it. However, absence of a DMZ alone does not prove that such an architecture is the best security design. External exposure, firewall rules, NAT traversal, segmentation, and organizational policy must be assessed. Huawei SC supports relevant traversal functions but cannot eliminate the need for proper network security. The intended examination answer is TRUE for the described non-DMZ option, with the deployment recommendation treated as conditional rather than mandatory.
