   What is the primary role of a Virtual Routing and Forwarding (VRF) instance?

   • ATo provide a separate routing table and forwarding table for each tenant.
   • BTo encrypt traffic between data center switches.
   • CTo filter traffic based on application layer information.
   • DTo load-balance traffic across multiple links.

   In a multitenant data center, how does VRF help with tenant separation?

   • AIt encrypts all traffic between tenants.
   • BIt assigns a unique MAC address to each tenant.
   • CIt provides a separate physical interface for each tenant.
   • DIt creates separate routing tables, preventing routes from leaking between tenants.

   A cloud provider wants to offer Infrastructure-as-a-Service to multiple customers while minimizing per-customer hardware costs. The provider expects variable demand and wants to maximize resource utilization across the customer base. Which architecture is most appropriate?

   • AMultitenant architecture with shared compute and network resources
   • BSingle-tenant architecture with dedicated servers per customer
   • CSingle-tenant architecture with virtualized servers per customer
   • DMultitenant architecture with dedicated VLANs per customer

   A data center operator is choosing between VLAN-based and overlay-based segmentation for a multitenant environment. The operator's primary concern is the ability to scale to thousands of tenants while keeping the physical network simple. Which approach should the operator choose?

   • AOverlay-based segmentation with MPLS to avoid encapsulation overhead
   • BOverlay-based segmentation because it provides a larger segment space and decouples tenant traffic from the physical topology
   • CVLAN-based segmentation with Q-in-Q to increase the segment count
   • DVLAN-based segmentation because it is simpler and requires no encapsulation

   In a multitenant data center, Tenant A and Tenant B use the same IP subnet (10.0.0.0/24) on different VRFs. The operator needs to ensure that traffic from Tenant A's VRF does not leak into Tenant B's VRF. Which configuration is required?

   • AEnsure that no route leaking is configured between the VRFs
   • BEnable VRF route target import/export for both VRFs
   • CConfigure a firewall filter on the shared physical interface
   • DUse the same VRF but different subnets for each tenant
