A network engineer is capturing packets on a VTEP's underlay interface to verify VXLAN encapsulation. The engineer observes a frame destined to a remote VTEP and needs to confirm that the original Ethernet frame is correctly preserved. Which fields in the captured packet should the engineer examine to validate the VXLAN encapsulation?

The outer MAC destination is the remote VTEP's MAC and the inner frame has a modified source MAC.

The outer UDP destination port set to 4789, the VXLAN header with a valid VNI, and the original inner Ethernet frame intact.

The outer IP protocol field set to 47 (GRE) and the inner frame's VLAN tag preserved.

The UDP source port is always 4789 and the VXLAN header contains a 24-bit VNI followed by a 32-bit reserved field.

Which benefit does VXLAN provide over traditional VLANs in a data center network?

VXLAN provides built-in security features like encryption and authentication

VXLAN eliminates the need for any IP addressing in the network

VXLAN supports up to 16 million segments, whereas VLANs are limited to 4094

VXLAN can only be used in leaf-spine topologies
