Huawei Certified ICT Expert – Routing and Switching (HCIE-RS) — Question 22

Which of the following statements about the Portal protocol are correct? (Choose all that apply.)

Answer options

• A. The Portal protocol describes protocol interaction between the Portal server and access devices. It is used to transfer parameters such as the user name and password.
• B. The Portal protocol uses the client/server structure and runs over UDP.
• C. The Portal protocol supports two authentication modes: CHAP and PAP. CHAP is more secure than PAP.
• D. Portal packets use the TLV format to carry attributes, such as the user name password, and MAC address.

Correct answer: A

Explanation

Option A is correct as it accurately describes the function of the Portal protocol in transferring user credentials. Option B is incorrect because the Portal protocol does not run over UDP; it typically operates over TCP. Option C is misleading since while CHAP is indeed more secure than PAP, the statement does not specify that both modes are supported. Option D is incorrect since it misrepresents the details carried by Portal packets.
