TCP/IP and the DoD Model

The Department of Defense created the DoD model which is made of four layers. What are they?

The Process/Application from the DoD model is equal to what layers in the OSI model?

The Host to Host layer from the DoD model is equal to what layer of the OSI model?

The Network Access of the DoD model is equal to what layers of the OSI model?

The DoD Process/Application Layer provides support on different applications. Which of these applications does it support?

Telnet is a protocol that its specialty is __________ ____________.

With File Transfer Protocol (TFTP) there is no authentication.

Post Office Protocol (POP) and Internet Message Access Protocol (IMAP) provides a storage facility for incoming mail. Its only used for receiving email.

Simple Mail Transfer Protocol (SMTP) is used to spool, queue, and send email only.

What is the well known port number for FTP?

What is the well know port number for Secured Shell and Telnet

What is the well known port numbers for HTTP and HTTPS?

What is the well known port numbers for SMTP and DNS?

DNS (Port 53) uses both TCP and UDP

What is the well known port numbers for SNMP and BOOTP/DHCP?

TCP is a full duplex, ______________ protocol that uses a virtual circuit for a sesssion, and UDP is a _____________ protocol that does not provide a virtual circuit for a session.

In the Dod Model, the only protocols that the Host to Host layer provide are TCP and UDP

TCP segment format contains a 16 bit source port and 16 bit destination port. It also contains a 32 bit sequencing number (when receiving segments) and a 32 bit acknowledgment (To request the next expected data via windowing)

UDP format does not sequence nor does it use any form of windowing so no acknowledgments are expected. Also it does not create a virtual circuit. The only format for UDP is a 16 bit Source port and a 16 bit destination port. It does have a 16 bit Length field and a 16 bit Checksum field along with the data.

Ports up to 1023 are considered to be well known port numbers as defined by the RFC 3232.

In the Dod Model the Internet Layer, what are the protocols supported?

What are the ports used in the Internet Layer's IP header to provide over to the Host to Host layer of the DoD model for both TCP and UDP?

The Protocol field in the IP header for the Host to Host (DoD) and Transport (OSI) layers can also be using protocols aside from TCP and UDP. What are the protocols?

What finds a hardware address from a known IP address?

What finds an IP address from its known hardware address?

This is a technique by which a device on a given network answers the ARP queries for a network address that is not on that network.

Internet Protocol (IP) is a connection-less protocol

What are port numbers used for?

The four layers of the TCP/IP Stack are 1)_________, 2) _____________, 3) ____________, 4)_____________.

The four layers of the DOD model are 1) ___________, 2) ____________, 3)_____________, 4) _____________ .

The TCP/IP Protocol Suite is the networking model and a set of communication protocols used for the internet and similar networks.

What are the TCP/IP Protocols for the Application Layer? (Choose three)

What is the TCP/IP Stack Model protocols for the Transport Layer?

What are the TCP/IP Model protocols for the Internet Layer? (Choose three)

What are the TCP/IP Model Protocols for the Network Access layer? (Choose three)

What two protocols uses session multiplexing?

TCP uses port number ____ for FTP, and for Telnet ____ and for HTTP ______ when supporting Application layer services.

What of the following are considered "Well Known Ports"? (Choose two)
