Designing Cisco Enterprise Networks (ENSLD) — Question 16

Which control-plane technology allows the same subnet to exist across multiple network locations?

Answer options

• A. LISP
• B. VXLAN
• C. FabricPath
• D. ISE mobility services

Correct answer: A

Explanation

LISP (Locator/Identifier Separation Protocol) is designed to allow the same subnet to be present in multiple locations, facilitating seamless mobility and virtualization. VXLAN, FabricPath, and ISE mobility services do not provide the same capability to extend a subnet across different network locations in the same manner that LISP does.
