On a Linux workstation, the route command takes a long time before printing out the routing table. Which of the following errors does that indicate?
A.
The local routing information may be corrupted and must be re-validated using a routing protocol.
B.
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.
C.
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.
D.
The Linux Kernel Routing Daemon (LKRD) is not running and should be started using its init script or systemd unit.
E.
DNS resolution may not be working as route by default tries to resolve names of routers and destinations and may run into a timeout.
"The typical reason is that route tries to map the IP addresses in the table into their DNS names - and that can be quite slow because of the vagaries of the DNS system and your network."
Correct: E
"By default, this can be as long as 30 seconds! That means if a nameserver is not available, it will take a while before it tries the next one. And typically it won’t remind that this nameserver is down, so other DNS requests may have to experience the timeout as well."
