QUESTION 1 OF 5
What is the most compressed valid format of the IPv6 address 2001 0db8000000160000001b 20000056?
Correct Answer: D
IPv6 addresses can be compressed by removing leading zeros and replacing consecutive groups of
zeros with a double colon (). Here’s how to compress the address
20010db8000000160000001b20000056
Remove leading zeros from each segment
2001db8000000160000001b20000056 becomes 2001db801601b200056
Replace the longest sequence of consecutive zeros with a double colon (). In this case, the two
consecutive zeros between the 16 and 1b
2001db80161b200056
Thus, the most compressed valid format of the IPv6 address is 2001db80161b200056.

For each statement about bandwidth and throughput, select True or False.
Note You will receive partial credit for each correct selection.
Correct Answer: A
Statement 1 Low bandwidth can increase network latency.
True Low bandwidth can result in increased network latency because the network may become
congested, leading to delays in data transmission.
Statement 2 High levels of network latency decrease network bandwidth.
False High levels of network latency do not decrease the available network bandwidth, but they do
affect the perceived performance and throughput of the network.
Statement 3 You can increase throughput by decreasing network latency.
True Decreasing network latency can increase throughput because data can be transmitted more
quickly and efficiently without delays.
Bandwidth vs. Latency Bandwidth refers to the maximum rate at which data can be transferred over
a network path. Latency is the time it takes for a data packet to travel from the source to the
destination.
Low bandwidth can cause network congestion, which can increase latency as packets wait to be
transmitted.
High latency does not reduce the actual bandwidth but can affect the overall performance and
efficiency of data transmission.
Reducing latency can lead to higher throughput because the network can handle more data in a
given period without delays.
True Low bandwidth can result in increased network latency because the network may become
congested, leading to delays in data transmission.
Statement 2 High levels of network latency decrease network bandwidth.
False High levels of network latency do not decrease the available network bandwidth, but they do
affect the perceived performance and throughput of the network.

Move each protocol from the list on the left to its correct example on the right.
Correct Answer: A
The correct matching of the protocols to their examples is as follows
DHCP Assign the reserved IP address 10.10.10.200 to a web server at your company.
DNS Perform a query to translate companypro.net to an IP address.
ICMP Perform a ping to ensure that a server is responding to network connections.
Here’s how each protocol corresponds to its example
DHCP (Dynamic Host Configuration Protocol) is used to assign IP addresses to devices on a network.
In this case, DHCP would be used to assign the reserved IP address 10.10.10.200 to a web server.
DNS (Domain Name System) is used to translate domain names into IP addresses. Therefore, to
translate companypro.net to an IP address, DNS would be utilized.
ICMP (Internet Control Message Protocol) is used for sending error messages and operational
information indicating success or failure when communicating with another IP address. An example
of this is using the ping command to check if a server is responding to network connections.
These protocols are essential for the smooth operation of networks and the internet.

DNS (Domain Name System) DNS translates human - friendly domain names like "companypro.net"
into IP addresses that computers use to identify each other on the network.
DHCP (Dynamic Host Configuration Protocol) DHCP automatically assigns IP addresses to devices on
a network, ensuring that no two devices have the same IP address.
ICMP (Internet Control Message Protocol) ICMP is used for diagnostic or control purposes, and the
ping command uses ICMP to test the reachability of a host on an IP network.

QUESTION 4 OF 5
Which protocol allows you to securely upload files to another computer on the internet?
Correct Answer: A
SFTP, or Secure File Transfer Protocol, is a protocol that allows for secure file transfer capabilities
between networked hosts. It is a secure extension of the File Transfer Protocol (FTP). SFTP encrypts
both commands and data, preventing passwords and sensitive information from being transmitted
openly over the network. It is typically used for secure file transfers over the internet and is built on
the Secure Shell (SSH) protocol1.

QUESTION 5 OF 5
A local company requires two networks in two new buildings. The addresses used in these networks must be in the private network range. Which two address ranges should the company use? (Choose 2.) Note You will receive partial credit for each correct selection.
Correct Answer: A,D
The private IP address ranges that are set aside specifically for use within private networks and not
routable on the internet are as follows
Class A 10.0.0.0 to 10.255.255.255
Class B 172.16.0.0 to 172.31.255.255
Class C 192.168.0.0 to 192.168.255.255
These ranges are defined by the Internet Assigned Numbers Authority (IANA) and are used for local
communications within a private network 1 2 3 .
Given the options A. 172.16.0.0 to 172.31.255.255 falls within the Class B private range. B.
192.16.0.0 to 192.16.255.255 is not a recognized private IP range. C. 11.0.0.0 to 11.255.255.255 is
not a recognized private IP range. D. 192.168.0.0 to 192.168.255.255 falls within the Class C private
range.
Therefore, the correct selections that the company should use for their private networks are A and D.
