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: Intranet, Extranet, Client-server or Peer-to-peer?

Client-server

What is the basic purpose of the OSI Physical layer? -Coordinate rules for sending and receiving electrical signals. -Define when devices have access to the LAN. -Define how physical network devices are identified on a network. -Maintain a list of known networks and neighboring routers.

Coordinate rules for sending and receiving electrical signals.

Which of the following are included as part of the Data Link layer specifications? (Select two.) -Physical topology -Digital data conversion -Data transmission between hosts -Cable and connector specifications -Physical network device identification

Data transmission between hosts Physical network device identification

In the OSI model, which of the following functions are performed at the Application layer? (Select two.) -Enabling of communication between network clients and services. -Communication setup, maintenance, and teardown. -Standard setting for sending and receiving signals. -Integration of network functionality into the host operating system. -Device control for data transmission rates.

Enabling of communication between network clients and services. Integration of network functionality into the host operating system

Which of the following geographic network types is typically managed by a city as a public utility: Local area network (LAN), Wide area network (WAN), Personal area network (PAN) or Metropolitan area network (MAN)?

MAN

Your manager has asked you to implement a network infrastructure that will accommodate failed connections. Which of the following network topologies provides redundancy for a failed link? -Mesh -Star -Bus -Ring

Mesh

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

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? -Partial mesh -Bus -Star -Full mesh

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: Multiple access, Client-server, Polling or Peer-to-peer?

Peer-to-peer
