The protocol that should be used to establish a secure network connection for backups is SSH.
<h3>Secure Shell</h3>
SSH stands for <u>Secure Shell</u>. SSH is a <u>protocol that allows users to remotely control and modify servers</u>. SSH is commonly used by administrators to manage certain systems or applications remotely. So the admin can enter the computer via the network, then run various commands to modify or manage files from one computer to another.
SSH has several crucial functions for managing data transfer traffic. Specifically, the following are the functions and benefits of SSH:
- Securing remote access to SSH-enabled systems or network devices for the user and processing them automatically.
- SSH will automatically terminate the connection if there is suspicious activity on the connection used. So you can avoid various cyber threats such as IP and DNS spoofing, data manipulation, illegal tracking, and others.
- Perform automatic and secure file transfers.
- Launch commands securely on remote devices or systems.
- Perform secure component management of network infrastructure.

Answer:
Option (A) A successful WPS attack has occurred
Explanation:
- WPS stands for Wi-Fi Protected Setup.
- Its a network security protocol in the Wi-Fi which has a vulnerability.
- The connection to the Wi-Fi can be established through the router in four ways. They are
- (a) PIN method
- (b) Push button method
- (c) Near field communication method
- (d) USB Method.
- Out of all the modes to be connected to the network, the PIN method has a flaw in it.
- In this PIN method, an attacker can brute force the PIN (guessing the PIN by some techniques) and gain unauthorized access to the network.
- In the given case in the question, the network administrator finds that multiple unauthorized devices has gained access to the network.
- Option (A) is correct.
- Option (B) ARP Poisoning, (C) botnet and (D) Evil Twin attack are different and so are the wrong options.

Explanation:
The Hexa-decimal numbers have base 16 and includes numbers:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F
The given steps are performed to convert a decimal number to hexa-decimal number, here to convert decimal number 35 to hexa-decimal number:
- Divide 35 by 16
- Note the remainder, r which is 3 here and quotient which is 2
- Again divide 2 (quotient) by 16 and note the remainder, r' which is 2 and quotient is 0
- We will stop here as the quotient is now 0. Usually division by 16 is repeated until we get quotient = 0
- Now arrange the remainder in reverse order to get the hexa-decimal number as r'r
- The hexa-decimal number is
The keyboard combinations that can be used to capture and print out a one-slide presentation using MSWord, showing everything on the screen is Function key + PrtScr
<h3>What is a Key Combination?</h3>
This refers to the procedure that is used to combine two or more keys on the keyboard to execute a task.
Hence, we can see that the procedure that can be used to carry out the operation is:
- Enter the screen you want to capture and print
- Press the Function key, followed by the PrtScr. Please note this can vary slightly, depending on the keyboard.
