An Operator is trying to create 6,000 virtualized networks that are interconnected through a common Layer 2 closed user group. The Layer 2 networks must support both unicast and broadcast delivery. Because there is a 4K limitation when using VLANs, which IP-based overlay can accomplish this task?

A provider is offering services via several VNFs. After a major service outage, engineers find that the outage was due to a bug that caused a few of the VNFs to operate incorrectly. A new software version is available that fixes the problem. The new software also introduces new services that will be used by some of the VNFs. The old services still must be offered to a selected group of VNFs. How should the engineer proceed with the upgrade?

An SDN network is built using OpenFlow version 1.3 as the Southbound API. Both the master and slave SDN Controller have experienced a catastrophic failure. The switches are configured in Fail-Secure mode. How will the forwarding plane behave in this situation?
