A network administrator is designing a network for a company with two sites. Each site has multiple VLANs. The administrator wants to route traffic between VLANs at each site and also between sites. Which of the following designs is the most efficient?

Use a router at each site for inter-VLAN routing and a switch for the inter-site link

Use a Layer 3 switch at each site for inter-VLAN routing and a router for the inter-site link

Use a router at each site for both inter-VLAN and inter-site routing

Use a switch at each site for inter-VLAN routing and a router for the inter-site link

A switch receives a frame with a destination MAC address that is in its MAC address table and is associated with the same port on which the frame was received. What will the switch do?

It will forward the frame out the port associated with the destination

It will forward the frame out all other ports

It will broadcast the frame to all ports

A network has a router with a default route and a more specific route to a destination. The default route has a lower metric than the specific route. Which route will the router use to forward packets to that destination?

Both routes, because they are both valid

The specific route, because it has a longer prefix match

Neither route, because the metrics are different

The default route, because it has a lower metric

A network administrator is designing a network for a company that has a data center and a branch office. The data center has multiple servers on different subnets, and the branch office has a single subnet. The company wants to ensure low latency for server-to-server traffic in the data center and efficient routing between the data center and the branch office. Which design should be used?

Use a Layer 3 switch in the data center for inter-VLAN routing and a router for the WAN link to the branch office

Use a router in the data center for both inter-VLAN and WAN routing

Use a switch in the data center for inter-VLAN routing and a router for the WAN link

Use a router in the data center for inter-VLAN routing and a switch for the WAN link
