You are investigating connectivity issues on your LAN and have noticed that sometimes you
cannot use Telnet from RTA to RTB. Sometimes, Telnet sessions will disconnect on RTA with the
message “connection reset by peer.” However, you can ping from RTA to RTB at all times. What
is most likely the cause of this issue?

A.
Quality of service is configured on RTA, limiting the Telnet sessions.

B.
Quality of service is configured on RTB, limiting the Telnet sessions.

C.
Control Plane Policing is configured on RTB, limiting the Telnet sessions.

D.
On router RTB, the “login block” mode went to a “quiet period” for the IP address of RTA.

E.
Another device that is connected to the switch is using the same IP address as RTB.

F.
Another device that is connected to the switch is using the same MAC address as RTB.

Explanation:
When another device connected to the switch has the same IP address as the device from which
you are pinging, the ping will go through but you will not be able to use any network services such
as Telnet because the same IP address is been used by another device.
