A company is migrating from a legacy flat network to a virtual network architecture on Juniper devices. The primary goal is to improve security by isolating different departments (HR, Finance, Engineering). Which benefit of virtual networks directly supports this goal?

Virtual networks provide separate forwarding tables, preventing unauthorized routing between departments.

Virtual networks automatically encrypt all traffic between departments.

Virtual networks eliminate the need for firewall policies.

Virtual networks reduce the number of physical devices required.

Which configuration step is required to associate a logical interface with a routing instance on a Juniper device?

Set the interface as a member of the routing instance under the [edit routing-instances] hierarchy

Create a new VLAN and assign it to the interface

Physically connect the interface to a different switch port

Enable the interface for routing using the 'routing' command

What is the primary purpose of implementing virtual networks in a data center multitenancy environment?

To provide a single routing table for all tenants to simplify management

To increase the physical bandwidth available to each tenant

To replace the need for physical switches and routers in the data center

To allow multiple tenants to share the same physical infrastructure while keeping their traffic and resources logically separated

A data center operator uses Juniper QFX switches to host multiple tenants. Tenant A and Tenant B are on the same physical switch but must not see each other's traffic. The operator has configured separate routing instances for each tenant. What additional mechanism is essential to ensure that broadcast and multicast traffic from Tenant A does not leak to Tenant B?

Use a single VLAN for both tenants and rely on the routing instances for isolation.

Configure a firewall filter to block broadcast traffic between routing instances.

Configure separate VLANs for each tenant and map them to the respective routing instances.

Enable storm control on all interfaces to limit broadcast traffic.
