Huawei Certified ICT Associate – SD-WAN (HCIA-SD-WAN) — Question 19

Which of the following statements about fingerprint-based positioning technology are true?

Answer options

• A. The positioning engine generates a virtual fingerprint library through calculations based on the AP deployment and environment information.
• B. Terminals learn from each other to form a fingerprint library that can be shared.
• C. APs collect surrounding environment information to form a fingerprint library.
• D. The fingerprint map is obtained through onsite information collection.

Correct answer: D

Explanation

Answer D is correct because the fingerprint map is indeed created by collecting data directly from the environment at the location. Answers A, B, and C are incorrect as they misrepresent the fingerprint library's creation process, which relies primarily on onsite data rather than calculations or inter-device learning.
