model? (Choose two.)

  • data link
  • network
  • physical
  • session
  • transport

24. Refer to the exhibit. What is the destination MAC address of the Ethernet frame as it
leaves the web server if the final destination is PC1?

  • 00-60-2F-3A-07-DD


25. Fill in the blank.
ARP spoofing is a technique that is used to send fake ARP messages to other hosts
in the LAN. The aim is to associate IP addresses to the wrong MAC addresses.

26. Which statement is true about the TCP/IP and OSI models?

  • The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.
  • The TCP/IP network access layer has similar functions to the OSI network layer.
  • The OSI Layer 7 and the TCP/IP application layer provide identical functions.
  • The first three OSI layers describe general services that are also provided by the TCP/IP internet layer.

27. What OSI layer is responsible for establishing a temporary communication session
between two applications and ensuring that transmitted data can be reassembled in proper
sequence?

  • transport
  • network
  • data link
  • session

28. If the default gateway is configured incorrectly on the host, what is the impact on
communications?

  • The host is unable to communicate on the local network.
  • The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.
  • The host can communicate with other hosts on remote networks, but is unable to communicate with hosts on the local network.
  • There is no impact on communications.

29. Refer to the exhibit. PC1 issues an ARP request because it needs to send a packet to PC3. In
this scenario, what will happen next?

  • RT1 will forward the ARP request to PC3.
  • RT1 will send an ARP reply with its own Fa0/0 MAC address.
  • RT1 will send an ARP reply with the PC3 MAC address.
  • SW1 will send an ARP reply with its Fa0/1 MAC address.
  • RT1 will send an ARP reply with its own Fa0/1 MAC address.

30. Refer to the exhibit. Consider the IP address configuration shown from PC1. What is a
description of the default gateway address?

  • It is the IP address of the Router1 interface that connects the company to the Internet.
  • It is the IP address of the Router1 interface that connects the PC1 LAN to Router1.
  • It is the IP address of Switch1 that connects PC1 to other devices on the same LAN.
  • It is the IP address of the ISP network device located in the cloud.
