QUESTION NO: 1 Which of the following is true regarding the use of switches and hubs for network connectivity? A. Using hubs can increase the amount of bandwidth available to hosts. B. Hubs can filter frames. C. Switches increase the number of collision domains in the network. D. Switches do not forward broadcasts. E. Switches take less time to process frames than hubs take. Answer: C Explanation: A hub is a broadcast domain and a collision domain, while a switch is a broadcast domain, each interface is a collision domain. The switch is a device of data link layer, forwards and floods data frames based on the MAC address. The hub adopts the shared bandwidth working mode, while the switch adopts dedicated bandwidth. Switches increases the number of collisions domains in the network. Switches that are configured with VLANs will reduce the size of the collision domains by increasing the number of collision domains in a network, but making them smaller than that of one big,...

QUESTION NO:2  QUESTION NO:3 Which one of the following statements is the media access method that Gigabit Ethernet uses? A. CSMA/CA B. CSMA/CD C. point-to-point D. token passing  QUESTION NO:4 How does replacing a hub with a switch affect CSMA/CD behavior in an Ethernet network? A. In increases the size of the collision domain by allowing more devices to be connected at once. B. It effectively eliminates collisions. C. It reduces the total amount of bandwidth available to each device. D. It decreases the amount of time that a jam signal must be sent to reach all network devi...
