Which design consideration is important when implementing Layer 2 stretch across data center sites?

Disabling all security features

Ensuring all sites use the same routing protocol

Limiting the size of the Layer 2 domain to avoid excessive broadcast traffic

Using a single link between sites to simplify design

What is the purpose of using redundancy in a Layer 2 stretch DCI?

To reduce the need for routing protocols

To increase the number of VLANs

To ensure connectivity remains available if one link or device fails

How does VXLAN encapsulate Layer 2 frames for transport over an IP network?

It replaces the Ethernet header with an IP header

It uses MPLS labels to forward the frame

It adds a VXLAN header, UDP header, and IP header to the original Ethernet frame

It encrypts the frame and sends it over a secure tunnel
