An overhead diagram illustrating an office network setup with three zones (A, B, C) featuring laptops, switches, and servers, highlighting connectivity and potential issues like bandwidth and single points of failure.

Draw the current office network problem with three zones (A, B, C). - Each zone has 10 users connected to one unmanaged switch. - Each zone’s unmanaged switch connects to its own dedicated core router in the server room. - Each core router connects to a separate ISP line Problems to highlight: - Each zone has only one uplink cable. If it fails, the entire zone loses internet. - Bandwidth limitation: each zone’s 1Gbps uplink must be shared by 10 users (100 Mbps per user). - Unmanaged switches cannot support VLAN, ACL, or QoS. - Three separate core routers increase complexity and management overhead.
