What is a characteristic of a fault tolerant network?
- a network that protects confidential information from unauthorized access
- a network that can expand quickly to support new users 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*

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. If QoS is implemented on this network, what will be the priorities from highest to lowest of the different data types?
- financial transactions, audio conference, web page
- audio conference, financial transactions, web page*
- audio conference, web page, financial transactions
- financial transactions, web page, audio conference

1 Why is it useful categorize networks by size when discussing network design?

Knowing the number of connected devices will define how many additional layers will be added to the three-tier hierarchical network design.

Knowing the number of connected devices will define how many multilayer switches will be necessary at the core layer.

A high-level redundancy at the access layer may be better implemented if the number of connected devices is know.
