Which statement about VXLAN is true?
Suggested Answer: C Vote an answer
802.1Q VLAN identifier space is only 12 bits. The VXLAN identifier space is 24 bits. This doubling in
size allows the VXLAN ID space to support 16 million Layer 2 segments -> Answer 'VXLAN extends
the Layer 2 Segment ID field to 24-bits, which allows up to 4094 unique Layer 2 segments over
the same network' is not correct.
VXLAN is a MAC-in-UDP encapsulation method that is used in order to extend a Layer 2 or Layer 3
overlay network over a Layer 3 infrastructure that already exists.
