What is the role of a VTEP in a VXLAN network?

It provides the underlay routing protocol

It encapsulates and decapsulates VXLAN packets

A data center has two leaf switches acting as VTEPs, both connected to the same access switch via an Ethernet Segment (ES). The access switch is multihomed to both leaves. The design requires that both leaves forward traffic for the same VNI to provide load balancing, but the customer also needs to ensure that if one leaf fails, the other continues to forward without interruption. Which EVPN multihoming mode should be configured?

All-active mode, where both VTEPs forward traffic for the ES and use the same ESI to advertise the segment.

All-active mode with different ESIs on each leaf to allow independent forwarding.

Active-standby mode with a designated forwarder elected via the Spanning Tree Protocol.

Single-active mode, where only one VTEP forwards traffic and the other acts as a standby.

A network administrator is analyzing a packet capture from a VTEP and sees a frame with an outer UDP header. The administrator needs to confirm that this is a VXLAN-encapsulated frame and identify the VNI. Which part of the packet should the administrator inspect?

The outer MAC destination and the inner frame's source MAC address.

The UDP destination port and the VXLAN header's 24-bit VNI field.

The UDP source port and the inner Ethernet frame's VLAN tag.

The outer IP protocol field and the inner IP header's DSCP value.
