A network technician is documenting the physical topology of a campus and needs each Arista switch to automatically advertise and discover directly connected neighbors so a network diagram can be built. Which Layer 2 discovery capability from the fundamentals curriculum supports this task?
Explanation
The Neighbour Discovery topic explicitly covers building a network diagram using LLDP, which is used to discover directly connected neighbors [1][2]. Trunking, STP, and link aggregation serve other Layer 2 functions.
An engineer must configure routing between multiple VLANs but has only a single physical link between a router and a switch. According to the Inter-VLAN Routing topics, which two configuration approaches enable communication between VLANs?
Explanation
The Inter-VLAN Routing curriculum lists both Router on a Stick and Inter-VLAN Routing with SVIs as methods to route between VLANs [1][2]. Link aggregation and DHCP snooping serve different purposes.
