A company wants to create a virtual network that isolates development and production traffic while sharing the same physical infrastructure. What is the most efficient way to achieve this?

Use a single overlay network and rely on firewall rules for isolation.

Use VLANs on the same switches without any overlay.

Create two overlay networks with different VNIs on the same underlay.

Build two separate physical networks, one for each environment.

What is the main purpose of an overlay network?

To encrypt all traffic between data centers.

To provide the physical transport for data center traffic.

To replace the physical network with a software-defined alternative.

To create virtual logical topologies that are independent of the physical network.

A service provider is evaluating overlay control plane options for a VXLAN fabric. They have a requirement to support a large number of tenants and MAC addresses, and they want to minimize the amount of state that must be synchronized across the network. Which control plane approach is most appropriate?

OSPF with type-5 LSAs for MAC advertisement

Centralized controller with a full copy of the forwarding table on every leaf

BGP-EVPN with MAC-VRF and IP-VRF

Static VXLAN tunnels with manual MAC learning

Which statement correctly describes the role of an underlay network in a data center?

It creates virtual logical topologies that are independent of the physical infrastructure.

It provides the logical segmentation of traffic between tenants.

It provides the physical connectivity and forwarding path between network devices.

It is a software-defined controller that manages virtual network functions.
