Question 4 Complete 3.33 points out of 5.00 ComputerA and ComputerB are located on the same subnet in an organization's TCP/IP local area network (LAN). ComputerA needs to send a message to ComputerB. ComputerA knows ComputerB's IP address, but does not know ComputerB's MAC address. Select one or more: I a. Before sending a message to ComputerB, ComputerA must first issue an ARP broadcast to obtain ComputerB's MAC address. b. After ComputerA learns ComputerB's MAC address, the MAC address is stored in ComputerA's address table for future use. ARP packets used in this scenario are sent at the application layer. d. ComputerA can send a message directly to ComputerB without knowing ComputerB's MAC address. Before sending a message to ComputerB, ComputerA sends an ARP request only to a router, and the router responds with ComputerB's MAC address. e. 3/28/22, 1:50 AM Question 10 Complete 1.67 points out of 5.00 Quiz overs BUCN Chap 4-5 & Assignment 2, Complete prior to Lecture 5): Attempt review Select all statements that correctly describe types of routing. C. Select one or more: a. One disadvantage of dynamic routing compared to static routing is that routers need to dedicate more computing resources to update their routing tables. b. One advantage of dynamic routing is that the routing decisions are continuously updated to reflect the changing network conditions with the goal of selecting the best route in the network. Static routing is a type of centralized routing, because the routes are manually defined by a network manager from a central management point in the network. d. Link state routing protocols make routing decisions based only on the speed of the circuit of each route that exists in a network. e. If the route defined between two routers that use static routing fails, the routers automatically revert to dynamic routing in order to build a new route between the routers.
