• Telnet
• web
Jawab:
-> • DHCP

4. Which protocol is used by FTP to transfer files over the Internet?

-> • TCP
5. Which protocols are TCP/IP application layer protocols? (Choose two.)
• UDP
• FTP
• IP
• SMTP
• TCP
Jawab:
-> • FTP
• SMTP

6. Which of the following are layers of the TCP/IP model? (Choose three.)
• Application
• Physical
• Internet
• Network Access
• Presentation
Jawab:
-> • Application
• Internet
• Network Access
7. You are creating a network-based video game. What influences your decision about which transport protocol to use for the application?
• UDP will not disrupt the game to retransmit dropped packets.
• TCP provides extra acknowledgements that will ensure smooth video delivery.
• Both TCP and UDP can be used simultaneously to ensure speed and guaranteed delivery.
• Both TCP and UDP may slow transmission and disrupt game operation, so no transport protocol should be used.
Jawab:
-> • UDP will not disrupt the game to retransmit dropped packets.

Jawab:
-> • instant messaging
14. An Internet server is running both FTP and HTTP services. How does the server know which of these applications should handle an incoming segment?
• The packet header identifies it as an HTTP or FTP packet.
• The data in the segment is specially formatted for either HTTP or FTP.
• The segment destination port number identifies the application that should handle it.
• The source port number is associated with one of these well known server applications.
Jawab:
-> • The segment destination port number identifies the application that should handle it.

15. What term is used to describe how TCP/IP protocols are layered and interact to format, address, and transmit information across a network?
• protocol hierarchy
• protocol modeling
• protocol stack
• protocol layering
Jawab:
-> • protocol layering

16. What three items are contained in an Ethernet frame? (Choose three.)
• source IP address
• source MAC address
• destination IP address
• destination MAC address
• error-checking information
Jawab:
-> • source MAC address
• destination MAC address
• error-checking information

17. What information is contained in an IP header?
• source and destination IP addresses
• source and destination MAC addresses
• only destination IP and MAC addresses
• both source and destination IP and MAC addresses
Jawab:
-> • source and destination IP addresses

• 2
• 1
• 3
Jawab:
-> • 1

19. A device receives an Ethernet frame and recognizes the MAC address as its own. What does the device do to the message to get to the encapsulated data?
• removes the IP header
• removes the TCP header
• passes data to the application layer
• removes the Ethernet header and trailer
Jawab:
-> • removes the IP header

20. A client has decoded a frame and started the de-encapsulation process. In which order does the de-encapsulation process occur?
• 1) remove IP header
2) remove Ethernet header and trailer
3) remove TCP header
4) pass data to the application
• 1) add TCP header to data
2) add an IP header
3) add frame header and trailer
4) encode the frame into bits
• 1) remove Ethernet header and trailer
2) remove IP header
3) remove TCP header
4) pass data to the application
• 1) add TCP header to data
2) add Ethernet header and trailer
3) add an IP header
4) encode the frame into bits
jawab:
-> 1) remove Ethernet header and trailer
2) remove IP header
3) remove TCP header
4) pass data to the application

21. What is an advantage of the use of layers in the OSI reference model?
• It breaks network communications into larger parts.
• It increases complexity.
• It prevents changes in one layer from affecting other layers.
• It requires the use of single-vendor equipment for hardware and software communications.
Jawab:
-> It prevents changes in one layer from affecting other layers.
