Exam N10-008 topic 1 question 287 discussion

GPT picks (B) Layer 3 switch: "A Layer 3 switch is a network switch that operates at both Layer 2 (data link layer) and Layer 3 (network layer) of the OSI model. It can have multiple VLAN interfaces configured, each associated with a different virtual LAN (VLAN). These VLAN interfaces allow the Layer 3 switch to route traffic between VLANs, effectively acting as a router within the switch. The other options are typically not associated with the capability to have multiple VLAN interfaces: (A) Hubs operate at Layer 1 (physical layer) and do not have VLAN interfaces. (C) Bridges operate at Layer 2 (data link layer) and typically do not have multiple VLAN interfaces for routing between VLANs. (D) Load balancers are devices used for distributing network traffic across multiple servers or resources, and while they may have VLAN support, they are not primarily known for having multiple VLAN interfaces for routing purposes."

A Layer 3 switch can have multiple VLAN interfaces because it is a type of switch that can perform routing functions, including routing between VLANs. Each VLAN on the switch can be configured with a Layer 3 interface, allowing traffic to be routed between VLANs. In contrast, a hub is a Layer 1 device that simply repeats incoming data to all connected devices, and does not have the ability to create or manage VLANs. A bridge is a Layer 2 device that can connect multiple network segments, but does not perform routing functions or have the ability to create VLAN interfaces. A load balancer is typically used to distribute network traffic across multiple servers, and does not have the ability to create or manage VLANs.
