Question 144

On a regular users workstation the route command takes a long time before printing out the routing table. Which of the following errors does that indicate?

The local routing information may be corrupted and must be re-validated using a routing protocol.

One of the routers in the routing table is not available which causes the automatic router failure detection mechanism (ARF-D) to wait for a timeout.

There may accidentally be more than one default router in which case a default router election has to be done on the network in order to choose one router as the default.

DNS resolution may not be working as route by default tries to resolve names of routers and destinations and may run into a timeout.
