What is the primary purpose of an overlay network in network virtualization?

To manage the physical switches and routers in the data center.

To replace the physical network with a fully virtualized infrastructure.

To create logical tunnels that carry virtual network traffic over the physical network.

To provide direct physical connections between virtual machines.

What is the main function of a virtual router?

To provide physical connectivity to the internet.

To forward frames within the same broadcast domain.

To route packets between different virtual networks or subnets.

To store virtual machine images.

A company has two virtual networks in its cloud environment: one for web servers and one for database servers. The web servers must be able to initiate connections to the database servers, but the database servers should not be able to initiate connections back to the web servers. What should the administrator configure to meet this requirement?

A virtual switch with VLAN tagging

A network virtualization edge (NVE) with VXLAN

A virtual router with a security policy

A VXLAN tunnel between the two networks

Which statement correctly describes the relationship between the underlay and overlay networks?

The underlay network is used only for storage traffic.

The overlay network is completely independent of the underlay network.

The overlay network relies on the underlay network to forward its encapsulated traffic.

The underlay network is created by the overlay network.

An administrator is deploying a new virtual machine (VM) in a cloud environment. The VM must communicate with other VMs on the same virtual network. Which component is required to connect the VM's virtual NIC to the virtual network?
