Refer to the exhibit. After you apply the given configuration to a router, the DHCP clients behind the device cannot communicate with hosts outside of their subnet. Which action is most likely to correct the problem?
A.
Configure the dns server on the same subnet as the clients
Answer is correct, since question is "Which action is most likely to correct the problem?"
Means that the given set of command is missing something.
Since when we are configuring a DHCP server on a router:
conf t
service dhcp
ip dhcp pool <pool name>
network <network address of the pool>
default-router <ip address of the interface facing the hosts, or ip adress of the interface facing downstream clients>
dns-server <ip address of dns-server>
exit
The network command from within DHCP configuration mode accepts a prefix-length directly as an argument, as an alternative to a netmask.
The command is in the form "network network-number [mask | /prefix-length] [secondary]".
See https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_dhcp/configuration/15-sy/dhcp-15-sy-book/config-dhcp-server.html
The DNS sever does not need to be on the same subnet as your clients. You can double check this by going into your network settings and adjusting DNS to 1.1.1.1 or 8.8.8.8. You can check the before and after results with ipconfig /all in command prompt. Typically your default DNS server on your local network is your default gateway on SOHO routers but your SOHO router will send that DNS query up to the ISP and typically one of their DNS servers will answer your DNS query. Remember your router is typically getting DHCP information from the ISP as well.
and how would the default gateway ip address look in the given questions output?
