5. 【Pick One】 [Pick one] Which of the following statements about switch is incorrect? A. The speed of ports can be configured in switch B. The negotiation speed of the port will be the quicker one between switch and NIC C. The speed of switch ports is self-adaptive D. Backplane bandwidth should be twice the sum of all ports' highest speed of a switch

Which of the following statements accurately describe switches? Select all that apply.1 pointWhen a switch receives a data packet, it reads the MAC address of the destination device and maps it to a port. Some benefits to switches are effective control of traffic flow and improved network performance. Switches are less secure than hubs.A switch is a device that makes connections between specific devices on a network by sending and receiving data between them. 4.Question 4

Which of the following statement(s) is/are true for a circuit switched network? a. A communication link may be shared by more than connection. b. A communication link is dedicated to a connection and cannot be shared with other connections. c. The packet transfer delay between a pair of nodes may depend on the prevailing network traffic. d. It is more efficient for bursty traffic.

Which one of the following switches uses store and forward transmission?a.Packet switchingb.None of the abovec.Circuit switchingd.Both a and b

Refer to Exhibit The output that is shown is generated at a switch. Which three statements are true? (Choose three)Question 16Select one or more:All ports will be in a state of discarding, learning or forwarding.This switch must be the root bridge for all VLANs on this switch.Thirty VLANs have been configured on this switch.All designated ports are in a forwarding state.All interfaces that are shown are on shared media.The bridge priority is lower than the default value for spanning tree.

1.3-2 Packet switching versus circuit switching (1).  Which of the characteristics below are associated with the technique of packet switching? Select all correct answers. [Hint: more than one of the answers is correct].Group of answer choicesThis technique is used in the Internet.Resources are used on demand, not reserved in advance.Reserves resources needed for a call from source to destination.Data may be queued before being transmitted due to other user’s data that’s also queueing for transmission.Frequency Division Multiplexing (FDM) and Time Division Multiplexing (TDM) are two approaches for implementing this technique.This technique was the basis for the telephone call switching during the 20th century and into the beginning of this current century.Congestion loss and variable end-end delays are possible with this technique.
