Refer to the exhibit. Based on the information given, which switch will be elected root bridge and why?

Switch A, because it has the lowest MAC address

Switch A, because it is the most centrally located switch

Switch B, because it has the highest MAC address

Switch C, because it is the most centrally located switch

Switch C, because it has the lowest priority

Switch D, because it has the highest priority

Which layer in the OSI reference model is responsible for determining the availability of the receiving program and checking to see if enough resources exist for that communication?

Refer to the graphic. Host A is communicating with the server. What will be the source MAC address of the frames received by Host A from the server?

The MAC address of router interface e0

The MAC address of router interface e1

The MAC address of the server network interface

The MAC address of host A

A router has two Fast Ethernet interfaces and needs to connect to four VLANs in the local network. How can you accomplish this task, using the fewest physical interfaces and without decreasing network performance?

Use a hub to connect the four VLANS with a Fast Ethernet interface on the router.

Add a second router to handle the VLAN traffic.

Add two more Fast Ethernet interfaces.

Implement a router-on-a-stick configuration.

A network administrator is verifying the configuration of a newly installed host by establishing an FTP connection to a remote server. What is the highest layer of the protocol stack that the network administrator is using for this operation?

A receiving host computes the checksum on a frame and determines that the frame is damaged. The frame is then discarded. At which OSI layer did this happen?

Which of the following correctly describe steps in the OSI data encapsulation process? (Choose two.)

The transport layer divides a data stream into segments and may add reliability and flow control information.

The data link layer adds physical source and destination addresses and an FCS to the segment.

Packets are created when the network layer encapsulates a frame with source and destination host addresses and protocolrelated control information.

Packets are created when the network layer adds Layer 3 addresses and control information to a segment.

The presentation layer translates bits into voltages for transmission across the physical link.

Refer to exhibit: Which two destination addresses will be used by Host A to send data to Host C? (Choose two.)

The IP address of Switch 1

The MAC address of Switch 1

The IP address of Host C

The MAC address of Host C

The IP address of the router's E0 interface

The MAC address of the router's E0 interface
