Personal b, 10 Base TX c, 100Base TX d 100BaseFX ____area networks can cover large geographic distances, including the entire Earth. a. Personal b. Local c. Wide d. Universal The most popular contention-based protocol is____ a. token ring b. round-robin c. carrier sense multiple access with collision avoidance (CSMA/CA) d carrier sense multiple access with collision detection (CSMA/CD) The interval during which the signals propagate down the bus and back is the____ a exponential back off b, collision window c. attention d. bounce window In CSMA/CA, the amount of time a device is made to wait before it can transmit is called the____ a. frame space (FS) b, frame time (FT) c, inter frame space (IFS) d intra frame time (IFT) A____ is a device that interconnects two or more workstations in a star-wired bus area network and immediately retransmits the data it receives from any workstation out to all other workstations connected a. hub b. switch c. router d. repeater A transparent bridge creates the internal port table by using a form of____ a forward learning b, backward correction c. backward learning d forward correction In a____ architecture, the data frame begins to exit the switch almost as soon as it begins to enter the switch. a. forward b, backward c. cut-through d. random-propagation

Explanation / Answer

38. (Option A)A Round Robin protocol is a protocol in which each workstation takes a turn at transmission, and the terms are uniformly distributed over all workstations.

39. (Option B) If a receiver has just received one packet of data with bytes number 600 to 700, it will respond immediately with an ACK of 701.
40. (Option D) The logical link control (LLC) sublayer is primarily responsible for logical addressing and providing error control and flowcontrol information.
41. (Option C) A 10BaseT system transmits 10-Mbps baseband (digital) signals over twisted pair for a maximum of 100meters per segment length.
