Chapter 4: Introduction to TCP/IP Protocols

How many bytes are used for an IPv4 address?

4

How many layers are in the TCP/IP?

4 Layers: Application, Transport, Internet, and Network Interface

In the TCP/IP protocol suite, ____ is the core protocol responsible for logical addressing.

ARP

A(n) ____ address represents any one interface from a group of interfaces, any one of which can accept a transmission.

Anycast

In IPv4 addressing, a node with an IP address of 168.34.88.29 belongs to a Class ____ network.

B

In most cases, BOOTP has been surpassed by the more sophisticated IP addressing utility, ____.

DHCP

The local host name plus its domain name.

DNS

Data are formed into packets known as ___.

Datagrams

____ ARP table entries are created when a client makes an ARP request that cannot be satisfied by data already in the ARP table.

Dynamic

Ports ranging from 49152 through 65535; open for use without restriction.

Dynamic Ports

If your network does not need or use APIPA, it must be uninstalled to avoid conflicts.

False

The format of ARP tables is the same from one operating system to another.

False?

In IPv6, each address contains a(n) ____, or a variable-length field at the beginning of the address that indicates what type of address it is.

Format Prefix

A UDP header contains ____fields.

Four

At a minimum, what fields would you find in a hosts file?

IP address and host name

Unreliable, connectionless protocol, which means that it does not guarantee delivery of data.

IPv4

Newer version of IP is...

IPv6, also known as IP next generation, or IPng.

To traverse more than one LAN segment and more than one type of network through a router

Internetwork

You issue a transmission from your workstation to the following socket address on your LAN: 10.1.1.145:110. Assuming your network uses standard port designations, what Application layer protocol are you using?

POP

A standard method or format for communication between network devices.

Protocol

Any hosts on the Internet that need to look up domain name information.

Resolvers

In IPv4 addressing, a 32-bit number that, when combined with a device's IP address, indicates what kind of subnet the device belongs to.

Subnet Mask

The specialized protocols that work together and belong to a protol suite.

Subprotocols

A core protocol of the TCP/IP suite.

TCP (Transmission Control Protocol) TCP belongs to the Transport layer and provides reliable data delivery services.

A suite of networking protocols that includes TCP, IP, UDP, and many others.

TCP/IP (Transmission Control Protocol/Internet Protocol)

The major subprotocols of the TCP/IP suite, including IP, TCP, and UDP.

TCP/IP Core Protocols

On a client/server network running TCP/IPv4, what computer initiates the process of assigning an IP address through DHCP?

The Client

____ is more efficient than TCP for carrying messages that fit within one data packet.

UDP

A core protocol in the TCP/IP suite that sits in the Transport layer of the OSI model.

UDP (User Datagram Protocol) A connectionless transport service.

Ports ranging from 0 to 1023; assigned to processes that only the operating system or an administrator of the system can access.

Well Known Ports

In the domain name www.google.com, ____ is the top-level domain (TLD).

com

Which of the following DNS records identifies a mail server?

mail1 IN MX 178.99.201.12
