Can a routing table in a datagram network have two entries with the same destination address?
In a datagram network, the destination addresses are unique. They cannot be duplicated in the routing table.
A router that uses the RIP routing protocol has an entry for a network in the routing table It then receives an update with another entry for the same destination network but with a lower hop count?
it will append the update information to the routing table

When the destination network is not listed in the routing table of a cisco router what two possible actions the router might take?
The router discards the packet.The router forwards the packet out the interface indicated by the default route entry.
What is routing overhead?
nodes often change their location within network. so, some stale routes are generated in the routing table which leads to unnecessary routing overhead.
Which can exist in a distance vector network that has not converged?
routing loopsinconsistent traffic forwardingno traffic forwarding until system convergesinconsistent routing table entriesrouting table updates sent to wrong destinations
When a router does not have an interface for the destination network it sends the traffic to where?
If a router has a route in its routing table, it will have a next hop IP address and / or outbound interface. If a router does not have a route in its routing table the packet will be dropped.
What address does the router use to compare to the routing table?
in general the router uses the network address to compare to the routing table. Specifically, on the internet, the Router looks up the destination IP address in the router table to determine where to route the packet.
