AP - Redundancy and Fault Tolerance

The network represents linked devices where a line shows a connection. Devices can only communicate through connections shown.

Which of the following best explains the ability of the network to provide fault tolerance?

• The network is considered fault-tolerant because there are redundant paths between each pair of devices.

• The network is considered fault-tolerant because it guarantees that no individual component will fail.

• The network is not considered fault-tolerant because it relies on physical connections.

• The network is not considered fault-tolerant because it provides more paths than are needed.

Which of the following best explains how fault tolerance in a network is achieved?

• By providing high-bandwidth connections between devices, enabling data packets to be transmitted as quickly as possible

• By providing multiple paths between devices, enabling routing to occur even in the presence of a failed component

• By providing open network protocols, ensuring that all devices on the network are interacting in a standard way

• By providing software to monitor all network traffic, ensuring that data packets are sent and received in the proper order

Which of the following best explains how the Internet is a fault-tolerant system?

• The Internet is fault-tolerant because cybercriminals can conceal their actions, allowing them the ability to carry out faulty actions without leaving a trace.

• The Internet is fault-tolerant because there are usually multiple paths between devices, allowing messages to sometimes be sent even when parts of the network fail.

• The Internet is fault-tolerant because users can transmit messages using a variety of different protocols, allowing them to use devices from any manufacturer.

• The Internet is fault-tolerant because users usually understand and accept the fact that servers sometimes fail, allowing network engineers to repair faulty devices as quickly as possible.

Which of the following statements is true about the ability of devices A and C to connect

• If devices B and D were to fail, then information sent from device A could not reach device C

• If devices B and F were to fail, then information sent from device A could not reach device C

• If devices E and F were to fail, then information sent from Device A could not reach device C

What is the minimum number of connections that would need to be removed from the network in order for device A to not be able to communicate with device F?

• 2

• 3

• 4

• 5
