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?
This is a link-local address.
This is a private IP address.
There is an IP address conflict.
This is a loopback address.
This is a private IP address.
Refer to the exhibit. An organization is using static NAT to translate the private IP address of Host A to a single public IP address leased from the ISP. Which address is the inside global address of Host A?
209.165.202.129
203.0.113.2
192.168.2.253
192.168.1.1
192.168.1. 10
209.165.202.129
Consider the following routing table entry for R1:
D 10.1.1.0/24 [90/2170112] via 209.165.200.226, 00:00:05, Serial0/0/0
What is the significance of the Serial0/0/0?
It is the interface on the final destination router that is directly connected to the 10.1.1.0/24 network.
It is the R1 interface through which the EIGRP update was learned.
It is the interface on the next-hop router when the destination IP address the 10.1.1.0/24 network.
It is the interface on R1 used to send data that is destined for 10.1.1.0/24.
It is the interface on R1 used to send data that is destined for 10.1.1.0/24
A device has an IPV6 address listed as 2001:0DB8:75a3:0214:0607:1234:aa10:ba01. What is the interface ID of the device?

0607:1234:aa10:ba01
In what two situations would UDP be the preferred transport protocol over TCP? (Choose two.)
when applications need to guarantee that a packet arrives intact, in sequence, and unduplicated
when a faster delivery mechanism is needed
when delivery overhead is not an issue
when applications do not need to guarantee delivery of the data
when destination port numbers are dynamic
when a faster delivery mechanism is needed
when applications do not need to guarantee delivery of the data
Refer to the exhibit. A computer that is configured with the IPv4 address as shown in the exhibit is unable to access the internet. What is the problem?
The gateway address is in the wrong subnet.
The IP address is a network address.
The settings were not validated.
The IP address is a broadcast address.
The gateway address is in the wrong subnet.
