TESTOUT OF NETW202
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? A.
C. Instant messaging is the only answer that is both text based and real time.
2. Which type of network provides customers with limited access to corporate data such as inventory, parts lists, and orders? A.
B. An extranet provides as-needed access for external vendors and customers to a secure corporate network. An intranet is for internal users.
are collaborative web pages created and edited by users.
4. What prioritizes traffic and its characteristics to manage data? A.
C. Considering the importance of traffic flow when managing data is a function of a quality of service (QoS) strategy. Network administrators would evaluate the network traffic to determine a QoS strategy.
5. Rules that govern the process of network communication are called protocols.
6. What network traffic processes must be in place for quality of service strategies to work correctly? (Choose two.) A.
Traffic is classified based on quality of service requirements. B.
Priorities are assigned to each classification of application data. C.
Web traffic is always assigned to a high-priority queue for processing. D.
Digital movies are always assigned to the high-priority queue for processing. E.
E-mail traffic is always assigned to the low-priority queue.
A, B. A quality of service strategy first classifies traffic based on requirements and then assigns priorities to the classifications as needed by the owners of the network. The network administrator can give different priorities to e-mail, web traffic, and movies.
7. Copper cables and fiber-optic cables are two types of network media.
8. What are two components of network architecture? (Choose two.) A.
People that comprise the human network
Built-in growth potential
Data transfer across the network
Corporations that operate and maintain the data network
B, D. Two components of a network’s architecture are scalability, which is planning for growth, and fault tolerance, which includes redundant links. The other answers describe either users of the network or the product of it (data transfer). 9. Symbols that graphically represent network devices and media are called icons. 10. For which three reasons were circuit-switched, connection-oriented technologies rejected when the Internet was being developed? (Choose three.) A.
Circuit-switched technologies required that a single message be broken up into multiple message blocks that contain addressing information. B.
Early circuit-switched networks did not automatically establish alternative circuits in the event of circuit failure. C.
Circuit-switched technologies required that an open circuit between network endpoints be established even if data was not being actively transferred between locations. D.
The quality and consistency of messages transmitted across a connection-oriented, circuit-switched network cannot be guaranteed. E.
The establishment of simultaneous open circuits for fault tolerance is costly.
B, C, and E. Circuit-switched networks did not automatically establish alternative circuits in the event of circuit failure and required that an open circuit between network endpoints be established, even if data was not being actively transferred between locations. Also, the establishment of simultaneous open circuits for fault tolerance is costly.
11. For which three reasons was a packet-switched, connectionless data communications technology used when developing the Internet? (Choose three.) A.
It can rapidly adapt to the loss of data transmission facilities. B.
It efficiently utilizes the network infrastructure to...
