FT III-FT IV TCP/IP STRUCTURE AND ADDRESSING (190E10-3) (lesson one practice questions)
A Class C address provides for a maximum of how many usable hosts?
254
Which three of the following are functions of the TCP/IP Internetwork Layer? (Choose three.)
A global addressing structure Packet fragmentation Service type requests
The TCP/IP model Application Layer maps to which three Open Systems Interconnection reference model (OSI/RM) layers? (Choose three.)
Application Layer - Session Layer - Presentation Layer
Transmission control protocol (TCP) includes which three types of mechanisms to ensure reliable data transmission? (Choose three.)
Checksum - Acknowledgements - Sequence number
Which TCP/IP Internetwork Layer provides troubleshooting utilities, such as ping and traceroute?
Internet Control Message Protocol (ICMP)
Which three of the following are included in the TCP/IP Internetwork Layer? (Choose three.)
Internet Group Management Protocol (IGMP). Internet protocol (IP). Address resolution protocol (ARP).
The Open Systems Interconnection Reference Model (OSI/RM) Data Link Layer serves which primary purpose?
It builds a flat network model with unroutable physical addresses.
Which is the primary purpose of the Open Systems Interconnection reference model (OSI/RM) Presentation Layer?
It defines the format in which Application Layer information is sent across the network.
Which of the following is the primary purpose of the Open Systems Interconnection Reference Model (OSI/RM) Transport Layer?
It defines well known logical port addresses for communications between applications.
Which is the primary purpose of the Open Systems Interconnection reference model (OSI/RM) Session Layer?
It establishes, manages, and terminates dialogs between Presentation Layer entities.
The Open Systems Interconnection Reference Model (OSI/RM) Application Layer serves which primary purpose?
It provides the user interface to the system.
The Open Systems Interconnection Reference Model (OSI/RM) Network Layer serves which primary purpose?
It uses Layer 3 (Network Layer) addresses to create multiple routed networks.
Which TCP/IP Application Layer protocol allows companies to publicly post information over the Internet?
Network News Transfer Protocol (NNTP)
The TCP/IP model Network Interface Layer maps to which Open Systems Interconnection reference model (OSI/RM) layer(s)? (Choose all that apply.)
Physical Layer, Data Link Layer
Which of the following best describes an email message's communication flow through the TCP/IP model layers?
The Transport Layer breaks the data stream into pieces, which it passes to the Internetwork Layer. The Internetwork Layer adds the source and destination Internet protocol (IP) addresses and forwards the packets to the Network Interface Layer. The Network Interface Layer builds frames, and converts them to bits for transport across the physical network.
The Internet Assigned Numbers Authority (IANA) recommends organizations use private IP addresses under which condition?
The network uses gateways, routers, or firewalls to act on the network host's behalf.
Which TCP/IP Transport Layer protocol provides an end-to-end, transaction-oriented, best-effort, connectionless service?
User Datagram Protocol (UDP)
Telnet is a protocol in which TCP/IP layer?
application
