Networking Concepts Quiz

Network Test Questions

• Layer 3 Device: A router operates at Layer 3 of the OSI model.
• DNS Application: Resolving human-readable domain names to machine-readable IP addresses is a common DNS application.
• ACL Purpose: Access Control Lists (ACLs) in networking define which users or devices can access specific network resources.
• Modem Function: A modem converts digital signals to analog signals (and vice-versa) for communication over telephone lines.
• Router Role: A router forwards data packets between networks based on IP addresses.
• Secure Communication Protocol: HTTPS is used for secure communication over the internet.
• Subnet Mask Purpose: A subnet mask determines the network and host portions of an IP address.
• Email Protocol: SMTP is used to send emails across the internet.
• DHCP Server Function: A DHCP server assigns IP addresses to devices in a network.
• Hub Device Type: A hub in networking broadcasts data to all connected devices.
• Secure Communication Protocol (HTTPS): HTTPS is used for secure communication over the internet.
• Subnet Mask Purpose (Networking): Subnet masks in networking are used to determine the network and host portions of an IP address.
• Network Integration Process: Network integration is the process of connecting different networks for data exchange.
• VPN Technology: VPNs are used to connect remote local networks over the internet.
• DNS Function: DNS resolves domain names to IP addresses.
• QoS Function: QoS ensures optimal network performance by prioritizing network traffic.
• WAN Example: The Internet is an example of a Wide Area Network (WAN).
• IP Gateway Function: An IP gateway connects different types of networks and routes data between them.
• Firewall Function: Firewalls filter and control incoming and outgoing network traffic.
• VLAN Function: VLANs logically segment a physical network into smaller, isolated networks.
• Fiber Optic Cable Benefit: Fiber optic cables offer higher data transmission speeds over longer distances.
• Real-Time Communication Protocol: SIP (Session Initiation Protocol) is used for real-time communication.
• LAN Device: A switch connects multiple devices within a single local area network (LAN).
• WAP Function: A wireless access point (WAP) provides wireless connectivity to devices in a network.
• Ethernet Cable Type: Twisted-pair cable is commonly used for wired Ethernet connections.
• Secure Data Transmission Protocol: HTTPS is used for secure data transmission across the internet.
• IP Spoofing: IP spoofing involves pretending to be another device by falsifying its IP address.
• Secure Wireless Communication: WPA2 (Wi-Fi Protected Access 2) is used to secure communication in wireless networks.
• DHCP Function: DHCP automatically assigns IP addresses to devices in a network.
• Layer 2 Device: A switch operates at Layer 2 of the OSI model.
• IP Address Purpose: An IP address uniquely identifies a device on a network.
• Broadcast Definition: Broadcasting in networking refers to sending data to all devices on a network.
• Email Sending Protocol: SMTP (Simple Mail Transfer Protocol) is the protocol used for sending emails.
• Single IP Address Sharing: NAT (Network Address Translation) allows multiple devices to share a single public IP address on a private network.
• Router Function (Networking): Routers direct data packets between different networks based on IP addresses.
• Load Balancing: Load balancing distributes network traffic across multiple servers or paths for optimal performance.
• Secure Connection over Public Network: A VPN (Virtual Private Network) is used to create a secure connection over a public network.
• Switch (Networking): A switch forwards data frames within the same network based on MAC addresses.
