Lesson 8.3 WGU C700 Secure Network Design. Questions and answers, 100% Accurate. In meshes - -How are routers organized? Gives ore reliability because it allows many possible alternative routes between endpoints - -Why are routers organized in meshes? f ind all rows that apply to an incoming packet. - -What must a router do first when routing a packet? It will will look at every row in the table to see if it is a match to the packet's destination and pick the best alternative route from the list of matches. routing table - -What does a router use to help make routing decisions? rows; a route for a range of IP addresses - -What does a routing table have? What do they represent? No, it only needs a row for each group of IPv4 addresses - -Does a routing table need a row for each IPv4 address? Yes - -Do routers perform calculation on all rows? Steps 1. find which of the rows in the routing table match the destination IPv4 address in an arriving packet - -What is step 1 out of 3 in how a router use its routing table to make routing decisions? Find the best-match row with the longest match (initial 1s in the row mask) - -What is step 2 out of 3 in how a router use its routing table to make routing decisions? if there is a tie on longest match, select among the tie rows based on: cost for metric (choose row with longest metric value) or speed metric (choose row with highest metric value) - only when needed - What is the tie-breaker rule in step 2 out of 3 in how a router use its routing table to make routing decisions? Send the packet back out the interface designated in the best match row - -What is step 3 out of 3 in how a router use its routing table to make routing decisions?
