Demo Questions

Question 1
Refer to the exhibit. What will Router1 do when it receives the data frame shown? (Choose three.) 
 
  

  • A: Router1 will strip off the source MAC address and replace it with the MAC address 0000.0c36.6965.
  • B: Router1 will strip off the source IP address and replace it with the IP address 192.168.40.1.
  • C: Router1 will strip off the destination MAC address and replace it with the MAC address 0000.0c07.4320.
  • D: Router1 will strip off the destination IP address and replace it with the IP address of 192.168.40.1.
  • E: Router1 will forward the data packet out interface FastEthernet0/1.
  • F: Router1 will forward the data packet out interface FastEthernet0/2.



Question 2
Refer to the exhibit. Which three statements correctly describe Network Device A? (Choose three.) 
 
  

  • A: With a network wide mask of 255.255.255.128, each interface does not require an IP address.
  • B: With a network wide mask of 255.255.255.128, each interface does require an IP address on a unique IP subnet.
  • C: With a network wide mask of 255.255.255.0, it must be a Layer 2 device for the PCs to communicate with each other.
  • D: With a network wide mask of 255.255.255.0, it must be a Layer 3 device for the PCs to communicate with each other.
  • E: With a network wide mask of 255.255.254.0, each interface does not require an IP address.



Question 3
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?

  • A: transport
  • B: network
  • C: presentation
  • D: session
  • E: application



Question 4
Which of the following describes the roles of devices in a WAN? (Choose three.)

  • A: A CSU/DSU terminates a digital local loop.
  • B: A modem terminates a digital local loop.
  • C: A CSU/DSU terminates an analog local loop.
  • D: A modem terminates an analog local loop.
  • E: A router is commonly considered a DTE device.
  • F: A router is commonly considered a DCE device.



Question 5
Refer to the exhibit. 
 
  

Host A pings interface S0/0 on router 3. What is the TTL value for that ping?

  • A: 252
  • B: 253
  • C: 254
  • D: 255



Question 6
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: application
  • B: presentation
  • C: session
  • D: transport
  • E: internet
  • F: data link



Question 7
Refer to the exhibit. After HostA pings HostB, which entry will be in the ARP cache of HostA to support this transmission? 
 
  

  • A:
      
  • B:
      
  • C:
      
  • D:
      
  • E:
      
  • F:
      



Question 8
A network interface port has collision detection and carrier sensing enabled on a shared twisted pair network. From this statement, what is known about the network interface port?

  • A: This is a 10 Mb/s switch port.
  • B: This is a 100 Mb/s switch port.
  • C: This is an Ethernet port operating at half duplex.
  • D: This is an Ethernet port operating at full duplex.
  • E: This is a port on a network interface card in a PC.



Question 9
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?

  • A: physical
  • B: session
  • C: data link
  • D: transport
  • E: network



Question 10
Which of the following correctly describe steps in the OSI data encapsulation process? (Choose two)

  • A: The transport layer divides a data stream into segments and may add reliability and flow control information.
  • B: The data link layer adds physical source and destination addresses and an FCS to the segment.
  • C: Packets are created when the network layer encapsulates a frame with source and destination host addresses and protocol-related control information.
  • D: Packets are created when the network layer adds Layer 3 addresses and control information to a segment.
  • E: The presentation layer translates bits into voltages for transmission across the physical link.
