Routing-Concepts-and-IP-Addresses-Assessment

Identify different classes of IP addresses (A, B, C, D, E).

Evaluate responses using AI:

OFF

Answer explanation

IP addresses are classified as follows: Class A (1.0.0.0 to 126.255.255.255), Class B (128.0.0.0 to 191.255.255.255), Class C (192.0.0.0 to 223.255.255.255), Class D (224.0.0.0 to 239.255.255.255 for multicast), and Class E (240.0.0.0 to 255.255.255.255 for experimental use).

Recall the structure of an IP address and the purpose of subnet masks.

Evaluate responses using AI:

OFF

Answer explanation

An IP address consists of four octets (e.g., 192.168.1.1) that identify a device on a network. Subnet masks determine the network and host portions of the IP address, enabling efficient routing and network management.

Define the term 'static route' and explain its significance in networking.

Evaluate responses using AI:

OFF

Answer explanation

A static route is a manually configured path for data packets in a network. Its significance lies in providing predictable routing, enhancing security, and optimizing traffic flow by avoiding dynamic routing protocols.

Interpret a subnet mask and determine the number of possible subnets and hosts.

Evaluate responses using AI:

OFF

Answer explanation

A subnet mask defines the network and host portions of an IP address. To find subnets, use 2^n (where n is the number of bits borrowed). For hosts, use 2^h - 2 (where h is the number of host bits). This helps determine possible subnets and hosts.

Compare and contrast the differences between static and dynamic routing.

Evaluate responses using AI:

OFF

Answer explanation

Static routing involves manually setting routes, making it simple but less adaptable. Dynamic routing uses protocols to automatically adjust routes based on network changes, offering flexibility and scalability but requiring more resources.

Evaluate the effects of subnetting on network performance and scalability.

Evaluate responses using AI:

OFF

Answer explanation

Subnetting improves network performance by reducing broadcast domains, leading to less congestion. It enhances scalability by allowing networks to grow efficiently, as new subnets can be added without disrupting existing ones.

Judge the effectiveness of static routing in different network scenarios.

Evaluate responses using AI:

OFF

Answer explanation

Static routing is effective in small, stable networks with few changes, as it requires minimal overhead. However, in dynamic or large networks, it can lead to inefficiencies and increased management complexity due to manual updates.

Recall the steps involved in sending a web request from a browser to a server.

Evaluate responses using AI:

OFF

Answer explanation

To send a web request, the browser constructs an HTTP request, establishes a TCP connection to the server, sends the request, and waits for a response. The server processes the request and sends back the appropriate data.

List the functions of an IP address in a network.

Evaluate responses using AI:

OFF

Answer explanation

An IP address serves several functions in a network: it uniquely identifies devices, facilitates communication between them, enables routing of data packets, and allows for location addressing within the network.

Evaluate the necessity of a default gateway in a network setup.

Evaluate responses using AI:

OFF

Answer explanation

A default gateway is essential in a network setup as it serves as the access point for devices to communicate with external networks. Without it, devices can only communicate within their local network.
