Network and Transport Layer PE

Question 1

Devices use what protocol to communicate problems with data transmission?

Answer 1

ICMP

Question 2

ICMP works in conjunction with TCP and UDP. T or F

Answer 2

false

Question 3

You are introducing a new computer to your LAN, which primarily uses IPv6 for its network functionality. Assuming you did not configure information on it, regarding default its adjacent devices, or general network configuration, what protocol would the computer use to discover other devices in its network?

Answer 3

NDP (neighbor discovery protocol)

Question 4

TCP is faster and UDP is more reliable. T or F

Answer 4

False

Question 5

UDP is considered a _______ protocol, which allows it to support protocols that require faster transmission.

Answer 5

connection-less

Question 6

Protocols such as FTP, SSH, and Telnet all employ ______ to ensure connection-oriented transmission.

Answer 6

TCP

Question 7

In order to allow devices to share information over a network in a connection-oritented manner, TCP communication uses a ______ to ensure that both nodes involved are ready for transmission.

Answer 7

three way handshake

Question 8

______ allows multiple devices to share a single IP address, allowing all the devices to receive the same data.

Answer 8

IGMP (internet group management procotol)

Question 9

What “traceroute” option switch in linux tells the protocol to not resolve IPs to hostnames, allowing you to get your results faster?

Answer 9

-n

Question 10

What diagnostic tool allows you to trace the pathway that a packet travels?

Answer 10

traceroute

Question 11

You are on a Linux system, and have been tasked with finding a specific route that your unit can use to send an exploit to an adversary on the IP 50.64.0.33, with the hope that they can find a path within 50 hops.
Which command would you use to find the exact path they will take, assuming you do not want traceroute to resolve domain names for the IP address?

Answer 11

traceroute 50.64.0.33 -n -m 50

Question 12

As traffic begins transmission, heading towards a web server, it breaks into smaller pieces due to it being 2000 Bytes in length. This process, referred to as Segmentation, happens because of what Transport Layer concept/protocol?

Answer 12

TCP
