Question 1 of 30
In a large enterprise network utilizing both underlay and overlay architectures, a network engineer is tasked with optimizing the performance of a multi-tenant application that relies on both Layer 2 and Layer 3 services. The engineer decides to implement an overlay network using Virtual Extensible LAN (VXLAN) to encapsulate tenant traffic. Given that the underlay network is based on a traditional IP routing architecture, which of the following considerations is most critical for ensuring efficient communication between the overlay and underlay networks?
Ensuring that the underlay network has sufficient bandwidth and low latency to support the encapsulated traffic without introducing significant overhead.
Configuring the overlay network to use a single multicast group for all tenant traffic to simplify management.
Implementing Quality of Service (QoS) policies exclusively on the overlay network to prioritize tenant traffic.
Relying solely on the underlay network's routing protocols to manage tenant traffic without any additional configuration.
