Authentication-free rules allow unauthenticated users to access essential services before login.

The following traffic must be allowed before authentication:

DNS traffic→ Users need to resolve domain names for the Portal page.

Portal page access→ The captive portal must be reachable.

RADIUS server communication→ Users must authenticate via RADIUS.

Why is this statement true?

Understanding the Differences Between HWTACACS and RADIUS:

HWTACACS(Huawei Terminal Access Controller Access-Control System) is aHuawei-enhanced version of TACACS+used forAAA (Authentication, Authorization, and Accounting).

RADIUS (Remote Authentication Dial-In User Service)is also an AAA protocol but is mainly designed fornetwork access authentication, such asVPNs and wireless authentication.

Why is Option B Correct?

HWTACACS supports per-command authorization, meaning administrators canassign different command privileges to different users.

For example, ajunior network engineer may be allowed to view configurations but not modify them, while asenior engineer has full access.

RADIUS does not support granular command authorization, as it primarily controlsnetwork accessrather than device management.
