Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 406

Which of the following are benefits from implementing the use of VXLAN’s in a network? (Choose two)

Answer options

• A. Increased scalability since VXLAN extends the IF field to 24 bits, providing up to 16 million unique ID values.
• B. Makes the implementation of Spanning Tree more efficient.
• C. Can be used to replace layer 3 routing protocols and increase routing efficiency at layer 2.
• D. Supports Equal Cost Multi-pathing (ECMP) so that load balancing over multiple links can be used.

Correct answer: A, D

Explanation

Option A is correct because VXLAN indeed extends the identifier field to 24 bits, allowing for a significantly larger number of unique identifiers, enhancing scalability. Option D is also correct as VXLAN supports ECMP, which enables efficient load distribution across multiple paths. Options B and C are incorrect as they do not accurately describe the benefits of VXLAN; VXLAN does not make Spanning Tree more efficient, nor does it replace layer 3 routing protocols.
