- FTP
- NAT
- PPP
16. Which two protocols function at the internet layer? (Choose two.)
- ARP
- BOOTP
- ICMP
- IP
- PPP
17. Which publicly available resources describe protocols, processes, and technologies for the Internet but do not give implementation details?
- Request for Comments
- IRTF research papers
- protocol models
- IEEE standards
18. Which address on a PC does not change, even if the PC is moved to a different network?
- IP address
- default gateway address
- MAC address
- logical address
19. What is the protocol that is used to discover a physical address from a known logical address and what message type does it use?
- ARP, multicast
- DNS, unicast
- DNS, broadcast
- ARP, broadcast
- PING, multicast
- PING, broadcast
20. What will happen if the default gateway address is incorrectly configured on a host?
- The host cannot communicate with other hosts in the local network.
- The switch will not forward packets initiated by the host.
- The host will have to use ARP to determine the correct address of the default gateway.
- The host cannot communicate with hosts in other networks.
- A ping from the host to 127.0.0.1 would not be successful.
21. What is an important function of the physical layer of the OSI model?
- It accepts frames from the physical media.
- It encapsulates upper layer data into frames.
- It defines the media access method performed by the hardware interface.
- It encodes frames into electrical, optical, or radio wave signals.
22. Which procedure is used to reduce the effect of crosstalk in copper cables?
- requiring proper grounding connections
- twisting opposing circuit wire pairs together
