   A network administrator is configuring routing zones on a Junos switch to isolate traffic between two departments. Each department will have its own routing instance. The administrator needs to ensure that the default gateway for each department is provided by the switch. What must be configured in addition to the routing instances?

   • AA VRRP group for each routing instance.
   • BA static route in the default routing table pointing to each department's subnet.
   • CA firewall filter to allow inter-VLAN routing.
   • DAn IRB interface for each department's VLAN, assigned to the respective routing instance.

   A data center administrator is designing network segmentation for a multi-tenant environment. Each tenant must have its own isolated routing table, but they will all share the same physical Junos switch. The administrator wants to use the simplest configuration that provides this Layer 3 isolation. Which approach should be used?

   • ACreate a separate VLAN for each tenant and use a single routing instance with IRB interfaces.
   • BUse a single routing instance and apply firewall filters to block inter-tenant traffic.
   • CConfigure a separate VRF for each tenant, but use the same route distinguisher (RD) for all.
   • DCreate a separate routing instance of type 'virtual-router' for each tenant and assign their respective interfaces to it.

   What is the primary purpose of a routing zone in Junos OS?

   • ATo define security policies that filter traffic between different network segments
   • BTo aggregate multiple physical interfaces into a single logical interface for higher bandwidth
   • CTo enable dynamic routing protocols to exchange routes with external networks
   • DTo provide a separate routing table and forwarding table for a set of interfaces

   What is the purpose of a route distinguisher (RD) in a VRF instance?

   • ATo make routes from different VRFs unique in a shared network
   • BTo encrypt routing information between VRFs
   • CTo specify the routing protocol used within the VRF
   • DTo define the import and export policies for the VRF
