1. Which form of communication is a real-time text-based communication type used between two or more people who use mostly text to communicate with each other?

  • Weblogs
  • Wikis
  • Instant Messaging
  • Podcasting
  • Collaboration Tools

2. Which type of network provides customer’s limited access to corporate data such as inventory, parts lists and orders?

  • intranet
  • extranet
  • internetwork
  • Internet

3. What balances the importance of traffic and its characteristics in order to manage data?

  • network administration
  • network traffic
  • QoS strategy
  • network evaluation

4. Which processes occur to network traffic so that quality of service strategies work correctly? (Choose two.)

  • Traffic is classified based on quality of service requirements.
  • Priorities are assigned to each classification of application data.
  • Web traffic is always assigned to a high priority queue for processing.
  • Digital movies are always assigned to the high priority queue for processing.
  • E-mail traffic is always assigned to the low priority queue.

5. What are two components of network architecture? (Choose two.)

  • people that comprise the human network
  • programmed services and protocols that move the messages across the network
  • data transferred across the network
  • technologies that support network communications
  • corporations that operate and maintain the data network

6. For which three reasons were circuit-switched, connection-oriented technologies rejected when the Internet was being developed? (Choose three.)

  • Circuit-switched technologies required that a single message be broken up into multiple message blocks that contain addressing information.
  • Early circuit-switched networks did not automatically establish alternative circuits in the event of circuit failure.
  • Circuit-switched technologies required that an open circuit between network endpoints be established, even if data was not actively being transferred between locations.
  • The quality and consistency of messages transmitted across a connection-oriented, circuit-switched network cannot be guaranteed.
  • The establishment of multiple, simultaneous open circuits for fault tolerance is costly.

7. For which three reasons was a packet-switched connectionless data communications technology used when developing the Internet? (Choose three.)

  • It can rapidly adapt to the loss of data transmission facilities.
  • It efficiently utilizes the network infrastructure to transfer data.
  • Data packets can travel multiple paths through the network simultaneously.
  • It allows for billing of network use by the amount of time a connection is established.
  • It requires that a data circuit between the source and destination be established before data can be transferred.

8. What is the role of QoS in a converged network?

  • ensures that all traffic above available bandwidth levels is dropped
  • establishes delivery priorities for different communication in a network
  • determines precise priorities for all network communication
  • allows unused bandwidth to be shared by other organizations within the network

9. Match the characteristics of a network architecture with their definitions by dragging the options on the left to targets on the right. (Not all options are used.)
