Refer to Exhibit, which statement about the configuration on the Cisco router is true?
A. The router sends only NTP traffic, using the loopback interface, and it disables eth0/0 from sending NTP traffic.
B. Eth0/0 sends NTP traffic on behalf of the loopback interface
C. The router sends only NTP traffic, using the eth0/0 interface, and it disables loopback0 from sending NTP traffic.
D. The router never sends NTP traffic, as using the loopback interface for NTP traffic is not supported on IOS routers.
I agree the best answer to be A; since you are in the eth0/0 interface and issuing the NTP disable command;
Answer A;
Use the ntp disable command in interface configuration mode to configure an interface to reject NTP packets. If the ntp disable command is configured on an interface that does not have any NTP service running, the interface remains disabled even after the NTP service is started by another NTP configuration. When you use the ntp disable command without the ip or ipv6 keyword, NTP is disabled on the interface for all the address families.
I think the best asnwer is A.
I agree, ntp is disabled on eth 0 but other interfaces we dont know, if not disables the ntp messages are sourced by loopback 0
