A hypervisor has multiple VMs connected to a virtual switch. The administrator wants to ensure that traffic between VMs on the same host does not leave the physical network. What is the behavior of the virtual switch in this scenario?

It forwards the traffic directly between the VMs without sending it to the physical network

It requires a virtual router to forward the traffic

It sends the traffic to the physical switch and back

It drops the traffic because it cannot route between VMs

Which component is associated with a virtual network interface?

A MAC address and an IP address.

A network architect is designing a VXLAN overlay for a data center. The architect needs to ensure that broadcast, unknown unicast, and multicast (BUM) traffic is handled efficiently. The underlay network does not support multicast. Which approach should the architect take?

Configure the underlay to support multicast

Use a central controller to forward BUM traffic

Disable BUM traffic in the overlay

Use head-end replication on the VTEPs

A VM is unable to communicate with other VMs on the same virtual network. The administrator checks the VM's configuration and confirms that the virtual NIC is attached to the correct virtual switch. What should the administrator check next?

The virtual router's routing table

The virtual NIC's IP address and subnet mask

The virtual switch's uplink configuration

What is the function of a Network Virtualization Edge (NVE)?

To filter traffic based on security policies.

To route traffic between virtual networks using BGP.

To provide the physical connection between the data center and the internet.

To encapsulate and decapsulate virtual network traffic at the edge of the overlay network.

Part of the Network Virtualization domain, which makes up ~10% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–6 in this domain), expect 1–2 from this objective — we provide 35 practice questions to prepare you well beyond it.
