112. You want to influence the root bridge selection within the LAN. Which value is used by spanning tree protocol to elect a root bridge?

1. Amount of RAM
2. Speed of the links
3. MAC Address
4. IOS Version

113. Which of the following are associated with the application layer (layer 7) of the OSI model?

1. TCP
2. Ping
3. Telnet
4. None of the above

114. Which line from the output of the show ip interface command indicates that there is a Layer 1 problem?

116. Users have noticed extremely slow network performance, intermittent connectivity, and connection losses. After entering the "show interfaces" command, you notice that the Ethernet interface is configured as 100 Mbps full-duplex and that there is evidence of late collisions. What could be the cause of this problem?

1. Trunking mode mismatch
2. Improperly configured root bridge
3. Duplex mismatch
4. A routing loop

117. While troubleshooting a connectivity problem on the network, you issue the ping command from your PC command prompt, but the output shows "request times out." At which OSI layer is this problem associated with?

1. The data link layer
2. The network layer
3. The access layer
4. The application layer

118. After making some network changes you power off and then power on your Cisco router named PC1. What sequence of events occurs when PC1 is powered up?

1. Perform POST
2. locate Cisco IOS software
3. load the Cisco IOS software
4. locate configuration statements

119. A receiving host on the network named PC1 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?

1. Application
2. Data Link
3. Presentation
4. Session

120. Network equipment supporting the use of flow control mechanisms has been recently installed in the network. What is the purpose of flow control in a data network?

1. It reassembles segments in the correct order on the destination device.
2. It provides a mechanism for the receiver to control the transmission speed.
3. It ensures that data is retransmitted if an acknowledgment is not received.
4. It regulates the size of each datagram segment.
