Question 1: Which protocol is used to automatically assign IP addresses to devices on a network?
- DNS
- DHCP (Correct answer)
- FTP
- SMTP
Correct answer: DHCP
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses and other network settings to devices when they connect.
Question 2: A sales associate notices that a customer's network uses WPA3. What is WPA3?
- A type of network cable
- A wireless security protocol (Correct answer)
- A VPN service

Question 3: Which of the following best describes a VPN?
- A device that blocks malware
- A network that creates an encrypted tunnel over a public network (Correct answer)
- A protocol for sending emails securely
- A type of network switch

A VPN (Virtual Private Network) creates an encrypted tunnel over a public network, allowing secure remote access to private network resources.
Question 4: What is the primary purpose of a network switch in a business environment?
- To connect a local network to the internet
- To assign IP addresses to devices
- To connect multiple devices within a LAN and forward traffic to the correct device (Correct answer)
- To protect the network from external threats
Correct answer: To connect multiple devices within a LAN and forward traffic to the correct device
A network switch connects multiple devices within a LAN and uses MAC addresses to forward data packets only to the intended recipient device.
Question 5: A customer asks about SSL certificates for their website. What is the main benefit of SSL?
- Faster website loading speeds
- Encrypted data transmission between the browser and server (Correct answer)
- Increased storage capacity
- Automatic software updates
Correct answer: Encrypted data transmission between the browser and server
SSL (Secure Sockets Layer) certificates encrypt data transmitted between a user's browser and the web server, protecting sensitive information from interception.
Question 6: What does the term 'bandwidth' refer to in networking?
- The number of devices connected to a network
- The maximum data transfer rate of a network connection (Correct answer)
- The physical size of network cables
- The number of IP addresses available
Correct answer: The maximum data transfer rate of a network connection
Bandwidth refers to the maximum rate at which data can be transferred over a network connection, typically measured in Mbps or Gbps.
Question 7: Which security measure requires users to provide two separate forms of verification before accessing a system?
- Single Sign-On (SSO)
- Multi-Factor Authentication (MFA) (Correct answer)
- Role-Based Access Control (RBAC)
- Network Access Control (NAC)
Correct answer: Multi-Factor Authentication (MFA)
Multi-Factor Authentication (MFA) requires users to provide two or more verification factors, such as a password plus a one-time code, before granting access.
