A technician replaces a failed router in an office with the same model unit using the default settings.
After the installation, the technician reboots all of the PCs and servers. Upon reboot some of the PCs
are receiving IP addresses on the same subnet as the new router; other PCs are receiving addresses
on the same subnet as the servers. Which of the following most likely describes the issue?
A.
The DHCP lease pool was not large enough
B.
DHCP lease times were set too low
C.
The router is not the only DHCP server
D.
DHCP was not enabled on the replacement router
How is the answer not D? Routers are not generally DHCP servers
Typically now a lot of organizations will use their network router as the DHCP Server to save money. But you are reading to far into the question. Look at the symptoms and rule out the unlikely answers. A and B are the unlikely. And it wont be D because some PC’s are receiving valid IP address’s instead of APIPA, so they are getting them from somewhere and they are specific to a subnet. Its not a great question but it’s one of those that CompTIA will throw at you to see if you can find the small clues.
