11 You have been asked to explain converged networks to a trainee. How would you accurately
describe a converged network?A network is converged when all routers have formed an adjacency.
A network is converged immediately after a topology change has occurred.
A network is converged when all routers flush the unreachable networks from their
routing tables.A network is converged after all routers share the same information, calculate best paths,
and update their routing tables.

OSPF elects designated routers on multiaccess links.
RIP does not advertise a route beyond a hop count of 15.
EIGRP uses broadcast traffic to establish adjacencies with its neighbors.

topology table when a successor route goes down.

Classful IP addresses can be used only when static routing is configured in the network.
Classful IP addresses allow the network/host boundary to occur at any bit in the 32-bit address.
The subnet mask for classful IP addresses can be determined by the value of the first octet of the IPaddress.
Classful IP addresses require the subnet mask to be included in the routing updates that are
