Exam N10-008 topic 1 question 162 discussion

A Layer 3 switch would allow this to occur, as it can segment the two departments by creating virtual LANs (VLANs) and routing traffic between them. A Layer 3 switch is a type of switch that can perform routing functions in addition to switching. It can use the network layer (Layer 3) of the OSI model to route traffic between different VLANs, which allows for the segmentation of different departments or networks within the same physical space. By creating VLANs for each department and using the Layer 3 switch to route traffic between them, the administrator can segment the two departments without the need for additional equipment.

GPT picks (C): "The option that would allow a systems administrator to use the least amount of equipment to segment two departments with cables terminating in the same room is (C) Layer 3 switch. A Layer 3 switch combines the functionality of both a switch and a router. It can create separate VLANs (Virtual Local Area Networks) for different departments while allowing them to connect through the same physical cables. This segmentation is achieved by using routing capabilities within the Layer 3 switch. Using a Layer 3 switch minimizes the need for additional equipment and provides efficient and isolated communication between the two departments."

You have to think like them. The real question is to check whether you know L3 switch supports VLAN (which could be used to segment).

C: Often referred to as a multilayer switch, a layer 3 switch adds a ton of flexibility to a network. The features of a layer 3 switch are: Comes with 24 Ethernet ports, but no WAN interface. Acts as a switch to connect devices within the same subnet. Switching algorithm is simple and is the same for most routed protocols.
