PCNSA Securing Traffic Practice Question

Which TWO of the following are methods to identify users for User-ID? (Choose two.)

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Captive Portal

Options A and E are correct. Captive Portal authenticates users directly by requiring them to log in, and User-ID Agent collects user-to-IP mappings from directory services like Active Directory. Option B (Kerberos Authentication) is a protocol used for authentication but not a dedicated User-ID method. Option C (LDAP Synchronization) is a method for synchronizing directory data, not for identifying users in real time. Option D (XML API) is an interface for configuration, not a standard User-ID identification method.
