Which device should be deployed?
- Router
- Switch
- Access point
- Firewall
Question 4
A technician needs to remotely access a Windows computer with a full graphical interface.
Which protocol should be used?
- Telnet
- SSH
- FTP
- RDP
Question 5
A user reports constant pop-up ads and browser redirects after installing a free application.
What is the most likely cause?
- Adware infection
- Rootkit
- Ransomware
- Worm
Answers and Explanations
Question 1:
Correct answer: SFTP
SFTP provides secure file transfer over SSH using port 22. It encrypts both authentication and data and operates over a single connection, making it secure and efficient for file transfers.
HTTP is an unencrypted protocol used for web traffic. It does not provide any security or file transfer protection.
FTP transfers files but does not encrypt data by default and uses separate channels, making it less secure.
HTTPS is used for secure web browsing, not as a standard file transfer protocol like SFTP.
Question 2:
Correct answer: 262 pins
DDR5 SO-DIMM modules use a 262-pin configuration, which ensures compatibility with modern laptop memory slots and supports newer memory technologies.
260 pins corresponds to DDR4 memory, which is not compatible with DDR5 systems.
288 pins is used for desktop memory modules and cannot fit in laptop slots.
204 pins is used by older DDR3 memory and is not compatible with newer systems.
Question 3:
Correct answer: Access point
An access point extends wireless coverage by allowing devices to connect to an existing wired network without creating a new network.
A router connects different networks and may create a new subnet, which is not required here.
A switch connects wired devices only and does not provide wireless connectivity.
A firewall filters network traffic but does not extend network coverage.
Question 4:
Correct answer: RDP
RDP allows full graphical remote access to a Windows system, enabling users to control the desktop environment remotely.
Telnet provides command-line access and is insecure because it does not encrypt data.
SSH provides secure command-line access but does not natively offer a full graphical interface like RDP.
FTP is used for file transfer and does not provide remote control capabilities.
Question 5:
Correct answer: Adware infection
Adware displays unwanted advertisements, pop-ups, and redirects, often after installing free or untrusted software.
A rootkit hides deep in the system to avoid detection but does not typically generate visible ads.
Ransomware locks files or systems and demands payment, which is not described here.
A worm spreads across networks automatically but does not usually cause pop-up ads.
