A typical campus network consists of the terminal layer, access layer, aggregation layer, core layer, egress zone, and O&M zone.

The statement is incorrect because it mischaracterizes the role of terminals within the network architecture. In a standard hierarchical campus network model, the network infrastructure is composed of the access, aggregation, and core layers. Terminals (such as PCs, IP phones, and IoT devices) are the end-user devices that connect to the access layer; they do not constitute a "terminal layer" of the network infrastructure itself. While a complete campus solution certainly includes terminals and functional areas like the egress and O&M zones, listing the "terminal layer" alongside the core infrastructure layers (access, aggregation, core) is architecturally inaccurate.

Why the "True" Option is Wrong:

Selecting "True" would endorse an incorrect network model. The hierarchical network design principle clearly separates the network infrastructure—which provides connectivity and services—from the endpoints (terminals) that consume those services. The layers (access, aggregation, core) refer specifically to the tiers of network equipment (switches and routers) and their topological roles.

The only alternative in a True/False judgement would be “False.” That is wrong because all six layers/zones listed in the statement are explicitly enumerated in Huawei’s reference architecture.

1. Huawei Enterprise Support Documentation: In the official documentation for Huawei's CloudCampus Solution, the network architecture is consistently described using a three-layer model for the network itself, supplemented by functional zones.

Reference Section: Chapter 2, "CloudCampus Solution 3.0 Architecture". This chapter details the physical network architecture, which consists of the access layer, aggregation layer, and core layer. It depicts terminals as endpoints connecting to the access layer, not as a separate layer of the network. The egress and management zones are described as distinct functional areas.

2. Huawei Certification Training Material: Official courseware for related Huawei certifications consistently teaches the standard hierarchical model.

Reference Section: Module 1, "Campus Network Overview". This section defines the roles and functions of the access, aggregation, and core layers. The curriculum explicitly positions end-user devices as connecting to the access layer, which serves as the entry point to the network infrastructure. There is no mention of a "terminal layer" as part of the infrastructure.
