Lab 12: TCP/IP Protocols - The Core Protocols

______ provides guarantees in its delivery and it creates point to point connection between hosts.

TCP

What control bit must be on to initiate the three-way handshake? 1) SYN 2) ACK 3) FIN 4) RST

1) SYN

What type of packet is an ARP reply? 1) Broadcast 2) Unicast 3) Multicast 4) Anycast

2) Unicast (a packet sent from point to point)

What control bit is used to indicate session termination? 1) SYN 2) ACK 3) FIN 4) RST

3) FIN

Why would an ARP frame have a destination MAC address of 00:00:00:00:00:00? 1) This is an error condition 2) This is an ARP information transfer 3) This is an ARP replay 4) This is an ARP request

4) This is an ARP request In the initial ARP request the IP address is known but the MAC address is not so the MAC address is all zeros.

TCP and UDP are __________ layer protocols. 1) Physical 2) Data Link 3) Network 4) Transport

4) Transport

What will using the ipconfig command show when used on its own? 1) name of the network interface 2) IP address 3) subnet mask 4) default gateway 5) All of the above

5) All of the above

What type of packet is an ARP request? 1) Broadcast 2) Unicast 3) Multicast 4) Anycast

1) Broadcast (a packet that is received by every device on the network)

What does the acronym ARP mean?

Address Resolution Protocol

The UDP protocol guarantees delivery by verifying sequencing for datagrams. True or False

False: The TCP protocol guarantees delivery through verification of sequencing.

What are the two types of packets used by the ARP protocol?

Request and Reply

TCP establishes a connection by using a _______ ________ __________.

Three Way Handshake

__________ protocol is used by some programs instead of TCP for fast, lightweight, unreliable transportation of data between hosts.

UDP

What command displays the current contents of the ARP cache on your computer?

arp -a

What command clears the current contents of the ARP cache on your computer?

arp -d

The UDP protocol data unit is a __________, not a segment.

datagram

On a Windows machine, what command can be entered at a command prompt to view your network configurations and to test communication with other computers?

ipconfig

What switch can be added to the ipconfig command to show more detailed information about TCP/IP settings?

ipconfig/all

What command can you use to verify network layer connectivity and that the host computer can connect to the network resources?

ping
