Resource summary

Question 1

Question
What is a characteristic of a fault tolerant network?
Answer
  • a network that protects confidential information from unauthorized access
  • a network that can expand quickly to support new user and applications without impacting the performance of the service delivered to existing users
  • a network that supports a mechanism for managing congestion and ensuring reliable delivery of content to all users
  • a network that recovers quickly when a failure occurs and depends on redundancy to limit the impact of a failure

Question 2

Question
Three bank employees are using the corporate network. The first employee uses a web browser to view a company web page in order to read some announcements. The second employee accesses the corporate database to perform some financial transactions. The third employee participates in an important live audio conference with other corporate managers in branch offices.
