Huawei Certified Network Professional – Routing and Switching v2 (HCNP-RS) — Question 33

Which of the following statements are false? (Choose three.)

Answer options

• A. An ASBR-Summary-LSA describes the route to an ASBR and is flooded within an AS.
• B. An ASE-LSA describes the route to an external AS and is flooded to an external AS.
• C. An AS-External-LSA does not belong to any specific area.
• D. The metric of a Type-1 external route is the AS external metric only.

Correct answer: A, B, D

Explanation

The correct answers are A, B, and D because an ASBR-Summary-LSA does not describe the route to an ASBR but rather summarizes routes to ASBRs, and an ASE-LSA is not flooded to an external AS. Furthermore, the metric for a Type-1 external route includes both the internal and external metrics, making D incorrect as well.
