Networking Basics and Administration

What is a routing protocol?

• A routing protocol is a set of rules for directing data packets across networks.

• A routing protocol is a method for storing data in databases.

• A routing protocol is a software application for web browsing.

• A routing protocol is a type of hardware used in networking.

What is the main difference between static and dynamic routing?

• Static routing is manually configured; dynamic routing adjusts automatically using protocols.

• Static routing uses protocols to adjust automatically.

• Static routing is faster than dynamic routing.

• Dynamic routing requires manual configuration.

What is the purpose of a default gateway?

• To connect multiple devices within the same network.

• The purpose of a default gateway is to route traffic from a local network to external networks.

• To assign IP addresses to devices on the network.

• To provide a backup for network connections.

Explain the concept of subnetting.

• Subnetting is the process of merging multiple networks into one.

• Subnetting is a method to increase the size of a network by adding more IP addresses.

• Subnetting refers to the practice of encrypting network data for security.

• Subnetting is the practice of dividing a network into smaller sub-networks to improve performance and security.

What is the role of a router in a network?

• A router stores data packets for later use.

• A router is used solely for wireless connections.

• A router directs data packets between networks and connects multiple devices.

• A router amplifies signals to boost network speed.

Define IP addressing.

• A method for encrypting data on a network.

• A protocol for connecting to the internet.

• IP addressing is a system for assigning unique numerical labels to devices on a network.

• A technique for managing network traffic.

What is the difference between IPv4 and IPv6?

• IPv4 is faster than IPv6 due to its smaller address size.

• IPv4 supports unlimited devices, while IPv6 is limited to 4 billion devices.

• IPv4 has a 32-bit address space, while IPv6 has a 128-bit address space.

• IPv4 uses hexadecimal addresses, while IPv6 uses decimal addresses.

What is a subnet mask?

• A subnet mask is used for data encryption.

• A subnet mask is a type of firewall.

• A subnet mask is used to determine the network and host portions of an IP address.

• A subnet mask defines the speed of a network connection.

What are the common classes of IP addresses?

• Class H

• Class G

• Class A, Class B, Class C, Class D, Class E

• Class F

What is the purpose of NAT (Network Address Translation)?

• To provide a direct connection between devices and the internet.

• To increase the speed of internet connections for all devices.

• The purpose of NAT is to enable multiple devices to share a single public IP address and enhance security by hiding internal IP addresses.

• To assign unique IP addresses to each device on a network.
