Question

Options

• APolicy control point device
• BiMaster NCE Campus Controller
• CPolicy enforcement point device
• DAuthentication point equipment

• A

• B
  10% (3)
• C
  10% (3)
• D
  3% (1)

Explanation

Option A is correct because "Policy control point device" is not a recognized core role in business travel network architecture - policy control is handled centrally by the controller (iMaster NCE), not by a dedicated endpoint device in this scenario.

Why the distractors are wrong (i.e., why B, C, and D ARE core roles):

• B (iMaster NCE Campus Controller) is the centralized management and policy decision engine that orchestrates the entire business travel solution.
• C (Policy Enforcement Point device) is the edge device that enforces the policies delivered by the controller, making it essential to the architecture.
• D (Authentication Point equipment) handles identity verification for traveling users before granting network access, a fundamental security step.

Memory tip: Think of the three real roles as a trio - Controller → Enforce → Authenticate. The controller (NCE) decides, the enforcement point acts, and the authentication point verifies. A "policy control point" sounds plausible but conflates the controller's job with a physical device role - if something sounds redundant with what the controller already does, it's likely the fake answer.
