Network Architectures

Choose the best definition to explain what is meant by a 'peer to peer' network.

• Computers have equal status and do not rely on a central server.  Each workstation is effectively a server and client.
• A client is used to make requests, the server processes these requests and then responds to the request.  The server provides a service.

Which one of these items is true of a peer-to-peer network?

• No network wide security in place
• Central control of security
• Has a central point of failure
• Easier to perform network wide backups

Which is a disadvantages of a client-server network?

• When server isn't on, clients don't power up
• Clients can't connect wirelessly to the server
• Dependent on server - if it goes down, clients stop working
• Clients are more expensive than servers

Which of the following is an advantage of a client-server network?

• Files and folders cannot be centrally backed up.
• Does not need an expensive server as individual workstations are used to access files.
• The server is expensive to purchase
• Files are stored in a centralised location, meaning it is easier to backup.

Which of the following is a disadvantage of a peer to peer network?

• Files and folders cannot be centrally backed up.
• Does not need an expensive server as individual workstations are used to access files.
• The server is expensive to purchase
• Files are stored in a centralised location, meaning it is easier to backup.

Which of the following is an advantage of a peer to peer network?

• Files and folders cannot be centrally backed up.
• Does not need an expensive server as individual workstations are used to access files.
• The server is expensive to purchase
• Network security can be carried out centrally.

Which of the following is an advantage of a peer to peer network?

• If one computer fails it will not disrupt the network.
• There is little or no security.
• Users can access shared data which is centrally controlled.
• If any part of the network fails, a lot of disruption can occur.

Which of the following is a disadvantage of a peer to peer network?

• If one computer fails it will not disrupt the network.
• There is little or no security which can leave them vulnerable.
• Users can access shared data which is centrally controlled.
• If any part of the network fails, a lot of disruption can occur.

Which of the following is NOT a description of a VLAN?

• It allows an administrator to segment networks.

• It is a logical partition of a Layer 2 network.

• It takes place inside a router.

• It is mutually isolated, and packets can only pass between them via a router.

Which of the following is NOT a benefit of VLAN?

• Sensitive data are separated from the rest of the network

• It increases the number of devices in the broadcast domain.

• Cost savings result from reduced need for expensive network upgrades.

• It reduces unnecessary traffic on the network and boosts performance
