   A network administrator is configuring a router that will be used by two different business units. Each unit must have its own routing table, and they use overlapping IP subnets. The router has a single physical interface connected to a switch that carries both units' traffic using VLANs. What should the administrator configure?

   • ACreate a single subinterface with a trunk and use one VRF for both units.
   • BUse the physical interface with a single IP address and rely on NAT to separate the units.
   • CConfigure a single VRF and use route maps to filter routes per unit.
   • DCreate subinterfaces for each VLAN and assign each subinterface to a different VRF.

   A company runs a web server on a VM. They want to deploy a new version of the application without changing the underlying OS or libraries. They also need to ensure that the new version runs in an isolated environment with its own filesystem. Which approach should they take?

   • AUse a container to package the new application version with its dependencies.
   • BRun the new version directly on the host alongside the VM.
   • CCreate a new VM with the same OS and install the new application version.
   • DReplace the VM's OS with a different distribution to match the new version's requirements.
