You have a network that uses a logical bus topology. How do messages travel through the network? 1) Messages are broadcast to all devices connected to the network. 2) Messages are sent to a central device that forwards them to the destination devices. 3) Messages are sent directly to the correct destination device. 4) Messages travel from one device to the next until they reach the destination device.

Messages are broadcast to all devices connected to the network.

You have a network that uses a logical ring topology. How do messages travel through the network? 1) Messages are sent directly to the destination device only. 2) Messages are sent to all devices connected to the network. 3) Messages travel from one device to the next until they reach the destination device. 4) Messages are sent to a central device that forwards them to the destination devices.

Messages travel from one device to the next until they reach the destination device.

Metropolitan area network (MAN)

Your manager has asked you to implement a wired network infrastructure that will accommodate failed connections. You don't have a large budget, so you decide to provide redundancy for only a handful of critical devices. Which of the following network topologies should you implement? 1) Star 2) Partial mesh 3) Full mesh 4) Bus

Partial mesh

You've implemented a network where each device provides all other devices on the network with access to shared files. Which type of network do you have? 1) Multiple access 2) Client-server 3) Peer-to-peer 4) Polling

Peer-to-peer

Ring

In the OSI model, what is the primary function of the Network layer? 1) Ensure that packets are delivered with no loss or duplication. 2) Transmit data frames. 3) Route messages between networks. 4) Enable communication between network clients and services

Route messages between networks.

You have a small network that uses a switch to connect multiple devices. Which physical topology are you using? 1) Mesh 2) Bus 3) Ring 4) Star

Star

During TCP/IP communication between two network hosts, information is encapsulated on the sending host and decapsulated on the receiving host using the OSI model. Match the information format with the appropriate layer of the OSI model. Layers: Transport layer Network layer Data Link layer Physical layer OSI Model: Bits Packets Frames Segments

Transport layer: Segments Network layer: Packets Data Link layer: Frames Physical layer: Bits

Bus

You've implemented a network where hosts are assigned specific roles, such as file sharing and printing roles. Other hosts access those resources, but they don't host services of their own. Which type of network do you have? 1) Client-server 2) Extranet 3) Intranet 4) Peer-to-peer

Client-Server

Which of the following tasks is associated with the Session layer? 1) Data block breakdown 2) IP address assignment 3) Connection establishment 4) Port number assignment
