Users have been unable to reach www.comptia.org from a Linux server. A systems administrator is troubleshooting the issue and does the following: Based on the information above, which of the following is causing the issue?
A.
The name www.comptia.org does not point to a valid IP address.
A default route is needed for a system to communicate with external networks (outside it's local subnet). There is no default route in output 4. It shows only a route for the local subnet 192.168.168.0/24. Without a default route, the system does not know where to send packets meant for external networks, which explains why it cannot reach www.comptia.org.
The answer should be C.
I can't see any default routes on this configuration. But the name server on the same subnet is reachable, and does appear to have a valid IP address.It looks like there is another typo on this question though. The broadcast address 192.168.169.255 is outside the subnet of 192.168.168.10/24. So any broadcasts at that IP would be useless when attempting to talk to 192.168.168.0/24 devices.
