A high school in New York (school A) is using videoconferencing technology to establish student
interactions with another high school (school B) in Russia. The videoconferencing is conducted between
two end devices through the Internet. The network administrator of school A configures the end device
with the IP address 209.165.201.10. The administrator sends a request for the IP address for the end
device in school B and the response is 192.168.25.10. Neither school is using a VPN. The administrator
knows immediately that this IP will not work. Why? - ✅✅✅CORRECT -This is a private IP address.

device drop the packet? - ✅✅✅CORRECT -when the value of the Hop Limit field reaches zero
What source IP address does a router use by default when the traceroute command is issued? -
✅✅✅CORRECT -the IP address of the outbound interface
What are the three IPv6 addresses displayed when the route from PC1 to PC2 is traced? (Choose three.) -
✅✅✅CORRECT -2001:DB8:1:1::1
