In a network topology with three routers connected in a triangle, Router A advertises a route to network 192.168.1.0/24 with a metric of 1560. Router B receives this update with a metric of 2130. What action will Router B take regarding this route?
A) Router B will consider Router A as a feasible successor for network 192.168.1.0/24.
B) Router B will ignore the route advertised by Router A.
C) Router B will recalculate the metric and advertise the route to Router C.
D) Router B will send a triggered update to Router A requesting more information.
Answer: A) Router B will consider Router A as a feasible successor for network 192.168.1.0/24.
In a network topology consisting of four routers, Router A is directly connected to networks 10.0.0.0/24 and 20.0.0.0/24. Router B is connected to networks 20.0.0.0/24 and 30.0.0.0/24. Router C receives updates from both Router A and Router B about the network 20.0.0.0/24. Which update will Router C prefer?
A) Router A’s update for network 20.0.0.0/24 with a metric of 4500
B) Router B’s update for network 20.0.0.0/24 with a metric of 3000
C) Router A’s update for network 20.0.0.0/24 with a metric of 2500
D) Router B’s update for network 20.0.0.0/24 with a metric of 5000
Answer: C) Router A’s update for network 20.0.0.0/24 with a metric of 2500
Consider a network topology where Router A is connected to networks 192.168.1.0/24 and 10.0.0.0/24. Router B is connected to networks 10.0.0.0/24 and 172.16.1.0/24. If Router A fails, which router(s) will Router B consider as feasible successors for the network 192.168.1.0/24?
A) Router B
B) None, as there are no feasible successors
C) Both Router B and the successor to Router A
D) Router A
Answer: B) None, as there are no feasible successors
In a network topology where Router A is connected to networks 10.0.0.0/24 and 20.0.0.0/24, and Router B is connected to networks 20.0.0.0/24 and 30.0.0.0/24, if the link between Router A and Router B fails, what will Router B do?
A) Router B will send a triggered update to Router A.
B) Router B will declare itself as the successor for all networks.
C) Router B will recalculate routes and update its routing table accordingly.
D) Router B will wait for Router A to send updates.
Answer: C) Router B will recalculate routes and update its routing table accordingly.
In a network topology with three routers, Router A is connected to networks 10.0.0.0/24 and 20.0.0.0/24, Router B is connected to networks 20.0.0.0/24 and 30.0.0.0/24, and Router C is connected to networks 30.0.0.0/24 and 40.0.0.0/24. If Router A advertises a route to network 40.0.0.0/24 with a metric of 3500, what will Router C do upon receiving this update?
