The Open Systems Interconnection reference model (OSI/RM) Network Layer serves which primary purpose? - correct answer It uses Layer 3 addresses to create multiple routed networks. The address 68.56.189.17 belongs to which Internet protocol (IP) class? - correct answer Class A What happens to a datagram sent by a higher level protocol to a 127.x.y.z address? - correct answer The datagram loops back inside the host and never leaves the network interface card (NIC). Which device evaluates and...

INSY 3303 Exam 1 Questions and Answers Already Passed Three basic components of a network: A server, client, and a circuit. What is a client? Is the inout-output device at the user end. (I.E. clients computer) What is a circuit? It is the pathway through which a message (data) travels. Think everything in-between the server and client, connects them together. What is a server? Typically servers provide some service for the clients. (data access, application logic, etc) Types of networks: LAN...

Cybersecurity Interview Questions and Answers 2024 - Networking Already Passed!! We will start with a set of cyber security interview questions based on networking. 01. What is the OSI model? Explain the different layers of the OSI model. The Open Systems Interconnection (OSI) model is a reference model that describes how applications interact with each other over a computer network. It has seven layers; they are as shown below: 1. Physical Layer: This is the lowest level of the OSI model....

What are advantages and disadvantages of a layered architecture? - Separation of concerns among logical layers promotes flexibility, scalibility, and maintainability. Multiple applications can reuse the components. It enables teams to work on different parts with minimal dependencies on other teams What are the similarities of the OSI model and five-layered Internet model? - They are both based on layered architecture. The are comparable to each other - see image 1 Both are networking stand...
