1. Which form of communication is a real-tem 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 list 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
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
- Corporation 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 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
