Questions: 7. A college is building a new dormitory on its campus. Workers are digging in the ground to install a new water pipe for the dormitory. A worker accidentally damages a fiber optic cable that connects two of the existing dormitories to the campus data center. Although the cable has been cut, students in the dormitories only experience a very short interruption of network services. What characteristic of the network is shown here? integrity quality of service (QoS) security fault tolerance scalability 8. What are two characteristics of a scalable network? (Choose two.) easily overloaded with increased traffic is not as reliable as a small network suitable for modular devices that allow for expansion offers limited number of applications

  1. The answer is the fourth one: fault tolerance.

Explanation:

  • Integrity: This refers to the accuracy and consistency of data over its lifecycle. It is not directly related to the ability of a network to continue functioning after a cable cut.
  • Quality of Service (QoS): This involves managing network resources to ensure the performance of specific applications, such as prioritizing voice traffic over data. It does not explain the network's ability to handle a cable cut.
  • Security: This pertains to protecting data and resources from unauthorized access or attacks. It is not relevant to the network's response to a physical cable cut.
  • Fault Tolerance: This is the ability of a network to continue operating properly in the event of a failure of some of its components. The fact that students experienced only a short interruption suggests that the network has redundancy or alternative paths, demonstrating fault tolerance.
  • Scalability: This refers to the ability of a network to grow and manage increased demand. It is not directly related to handling a cable cut.
  1. The two characteristics of a scalable network are:
  • Suitable for modular devices that allow for expansion.
  • Offers a limited number of applications.

Explanation:

  • Easily overloaded with increased traffic: This is not a characteristic of a scalable network. A scalable network should handle increased traffic without becoming easily overloaded.
  • Is not as reliable as a small network: This is incorrect. Scalability does not inherently affect reliability; a scalable network can be just as reliable as a small network.
  • Suitable for modular devices that allow for expansion: This is a characteristic of a scalable network, as it allows for growth and adaptation to increased demands.
  • Offers a limited number of applications: This is not typically a characteristic of a scalable network. A scalable network should support a wide range of applications as it grows. However, if interpreted as focusing on core applications to maintain performance, it could be seen as a characteristic in some contexts.
