Regarding routing and forwarding

A. forwarding is the process of determining the path that data will take and builds the forwarding table; routing uses the forwarding table to send the packet to the next hop in the network

B. forwarding is the process of determining the path that data will take and builds the routing table; routing uses the routing table to send the packet to the next hop in the network

C. routing is the process of determining the path that data will take and builds the routing algorithm; forwarding uses the forwarding table to send the packet to the next hop in the network

D. outing is the process of determining the path that data will take and builds the routing table; forwarding uses the routing table to send the packet to the next hop in the network Content provider networks

(Google, Microsoft, Netflix, Akamai, etc.)

A. are centrally located at the core of the Internet to save bandwidth, regardless of the cost

B. are connected to their local/regional ISP or local access ISP

C. are often connected to several Tier 1 ISPs as well as to large access ISPs to save on costs and bandwidth

D. are only allowed to connect to one tier 1 ISP at a time

A routing algorithm

A. runs each time a packet arrives at a router, and determines the best path for the packet to take

B. runs each time a packet arrives at a router, creating a table of routers for the packet to take through the network

C. runs each time the network configuration changes, and creates a forwarding table that can be used to make forwarding decisions

D. runs once when the network is designed, defining how all packets will traverse the network
