Which of the following is a benefit of the fault-tolerant nature of Internet routing?

The ability to use a hierarchical naming system to avoid naming conflicts

The ability to provide data transmission even when some connections between routers have failed

The ability to resolve errors in domain name system

The correct benefit of the fault-tolerant nature of Internet routing is:

The ability to provide data transmission even when some connections between routers have failed.

This characteristic ensures that the Internet can reroute traffic dynamically in case of failures, maintaining connectivity and allowing data to reach its destination despite the presence of faults in the network.

Which of the following statements are true about this network:

A - The network is fault tolerant. If one connection fails, any two devices can still communicate.
B - Computers C and E need to first communicate with at least one other device in order to communicate with each other.

A only

B only

A and B

Neither A nor B

To accurately determine the truth of statements A and B, we need to examine them in the context of the network's topology, which is not provided in your message. However, I can help you analyze the statements in a general context:

  • Statement A: "The network is fault tolerant. If one connection fails, any two devices can still communicate."

    • If the network is designed with redundant connections or pathways between devices (like in a mesh network), then this statement is likely true. In such cases, even if one connection fails, alternative paths still allow communication between devices.

  • Statement B: "Computers C and E need to first communicate with at least one other device in order to communicate with each other."

    • This statement would be true if computers C and E are not directly connected and require an intermediary device to relay messages. In a star topology or similar network configurations, this could often be the case.

Without knowing the specific network topology, we can't definitively declare A or B as true or false. However, here’s how you could evaluate them:

  1. If the network allows all devices to communicate directly with multiple alternate pathways, then A is true.
  2. If C and E can communicate directly without needing other devices, then B is false, and vice versa.

If you're familiar with the specific network layout, please provide that information so I can give a more accurate assessment. Otherwise, based on common network configurations:

  • If the network is fully interconnected or has sufficient redundancy, A would likely be true.
  • If C and E do not have a direct connection, B would be true.

So, it's possible that either just A, just B, both A and B, or neither applies based on the network's design. Please specify the network configuration if you need a precise answer.

What information is contained in a packet?

The entirety of a digital message

The entirety of a digital message, and metadata about the message, including where it came from and where it is going.

A small part of a digital message.

A small part of a digital message, and metadata about the message, including where it came from and where it is going.

Question: 2
True or False: All data sent over the Internet is broken down into several packets and sent over the network.

True

False

Question 1: What information is contained in a packet?

The correct answer is:

A small part of a digital message, and metadata about the message, including where it came from and where it is going.

Packets are used to break down large messages (such as files or streams of data) into smaller, manageable segments, each of which contains a portion of the message and metadata (such as source and destination IP addresses, sequence numbers, etc.).

Question 2: True or False: All data sent over the Internet is broken down into several packets and sent over the network.

The answer is:

True.

Most data sent over the Internet is indeed broken down into packets to facilitate transmission. This is a fundamental principle of how data is transmitted across networks to ensure efficient routing and delivery. Even larger files or data streams are divided into packets to adhere to the protocols and to manage network load effectively.
