1. Bianka, a Polish traveler in Hanoi, Vietnam, stops and asks Nguyệt for directions to the Ngoc Son Temple. They verbally communicate and determine that they both speak English. After receiving directions in English to the temple, Bianka repeats them to Nguyệt. Nguyệt says, “Yes, that is correct.” Select the order of the communications protocols used in this scenario?
- language, method, confirmation
- method, confirmation, language
- confirmation, method, language
- method, language, confirmation
Explanation: Bianka and Nguyệt first decided on the method of communication (verbal). Then they determined the that both speak English (language). Finally, Bianka repeated the directions (confirmation).
2. Rory is studying the fields inside an Ethernet frame for an upcoming test and notices that the destination Media Access Control (MAC) address is listed first before the source MAC address. Which of the following protocol characteristics is Rory investigating?
- encapsulation
- timing
- message pattern
- message timing
- encoding
Explanation: Networking protocols often have some type of addressing information to indicate the source and destination for the message.
3. As Rory continues to study Ethernet, he discovers that a frame can typically be 64 to 1518 bytes of information that is converted into a series of bits before being sent out on the network. Which two protocol characteristics did Rory learn about for Ethernet?
- message size
- timing
- encoding
- encapsulation
- message pattern
Explanation: Networking protocols typically specify the maximum size for a message. In the case of Ethernet, there is also a minimum size of 64 bytes. In addition, Ethernet specifies a method for encoding the bits so that the destination can decode the message.
