Which configuration best isolates department-level administration on a single appliance?

• A. Configure dedicated routes in the admin partitions for each department.
• B. Configure Policy-based Routes for each department in the nsroot partition.
• C. Configure admin partitions that use dedicated VLANs.
• D. Configure a SNIP in each partition and bind a VLAN for the department.

Answer: (C)

Separating management networks with dedicated VLANs for each admin partition provides true network-level isolation of department administration on a single appliance. By placing each partition on its own VLAN, you create distinct subnets and boundary points, ensuring administration traffic from one department cannot mix with or reach the management space of another. This strong boundary at the network layer is the most reliable way to keep admin activities siloed, which is exactly what’s needed for department-level isolation.

Other approaches don’t establish the same boundary. Routing configurations inside admin partitions or policy-based routes in the root partition don’t create a hard, multiline boundary between partitions’ management planes. They influence where traffic goes but don’t prevent cross-partition admin access. Binding VLANs and SNIPs per partition can contribute to separation, but using dedicated VLANs for each admin partition is the clear, robust method to isolate administration on a single appliance.
