Huawei Certified ICT Expert – Routing and Switching (HCIE-RS) — Question 46

Which of the following statements about the underlay network of a VXLAN-based virtualized campus network is incorrect?

Answer options

• A. The virtualized campus network solution introduces VXLAN technology, which uses MAC-in-UDP encapsulation to build a logical network over a traditional IP network.
• B. The underlay network provides IP reachability so that VXLAN-encapsulated service packets can be transmitted between VTEPs.
• C. When iMaster NCE-Campus is used to implement automatic orchestration of routing domains on the underlay network, only one routing protocol can be deployed in a single area.
• D. When iMaster NCE-Campus is used to implement automatic orchestration of routing domains on the underlay network, only OSPF is supported.

Correct answer: D

Explanation

The correct answer is D because iMaster NCE-Campus supports multiple routing protocols, not just OSPF, for orchestration of routing domains. Options A and B are true statements about the functionality of the VXLAN technology and the role of the underlay network. Option C is also accurate, as it correctly states the limitation regarding routing protocols in a single area.
