A customer has reached the limit of their IEEE Layer 2 VLAN implementation. The customer then switches to a VXLAN overlay architecture using Layer 3. In this scenario, how many unique VXLAN segments…

The correct answer is D. 16,777,216. Explanation/Reference: VXLAN is a header encapsulation technology that defines a 50 Byte wide header. The header itself includes a VXLAN ID (VNI or also called segment ID) field that is 24 bits wide allowing for 16,777,216 (2^24) unique VXLAN segments.
