Which statement about VXLAN is true?
A. VXLAN encapsulates a Layer 2 frame in an IP-UDP header, which allows Layer 2 adjacency across router boundaries.
B. VXLAN uses the Spanning Tree Protocol for loop prevention.
C. VXLAN extends the Layer 2 Segment ID field to 24-bits, which allows up to 4094 unique Layer 2 segments over the same network.
D. VXLAN uses TCP as the transport protocol over the physical data center network.

Which statement about VXLAN is true?
A. VXLAN encapsulates a Layer 2 frame in an IP-UDP header, which allows Layer 2 adjacency across router boundaries. B. VXLAN uses the Spanning Tree Protocol for loop prevention. C.

VXLAN uses TCP as the transport protocol over the physical data center network.
Explanation: 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.
