In Cisco IOS, what is the result of the ip dns spoofing command on DNS queries that are
coming from the inside and are destined to DNS servers on the outside?

A.
The router will prevent DNS packets without TSIG information from passing through
the router.

B.
The router will act as a proxy to the DNS request and reply to the DNS request with
the IP address of the interface that received the DNS query if the outside interface is
down.

C.
The router will take the DNS query and forward it on to the DNS server with its
information in place of the client IP.

D.
The router will block unknown DNS requests on both the inside and outside
interfaces.
