Describe the two different types of NAT.
(25) 
VerifiedTwo variations of NAT you need to be aware of are:
SNAT- Using Static Network Address Translation (SNAT),the gateway assigns the samepublic IP address to a host each time it makes a request to access the Internet.This methodworks well when a local host is running a server that is accessed from the Internet.It' sused on home networks that have only a single public IP address provided by an ISP.DNAT or Dynamic NAT- Using Dynamic Network Address Translation (DNAT),thegateway has a pool of public IP addresses that it is free to assign to a local host wheneverthe local host makes a request to access the Internet.Large organizations that leasemany public IP addresses use DNAT.
What utility is used to verify that TCP/IP installed,bound to the NIC,configured correctly,and communicating with the network?

Explain the three different tunneling protocols developed for transmission of IPv6 packets over or through an IPv4 network.
(34) VerifiedThree tunneling protocols developed for IPv6 packets to travel over or through anIPv4 network are:
6to4is the most common tunneling protocol.IPv6 addresses intended to be used bythis protocol always begin with the same 16-bit prefix (called fixed bits),which is 2002and the prefix is written as 2002::/16.The next 32 bits of the IPv6 address are the 32bits of the IPv4 address of the sending host.ISATAP (pronounced " eye-sa-tap" )stands for Intra-Site Automatic Tunnel AddressingProtocol .This protocol works only on a single organization' s intranet.By default,ISATAPis enabled in Windows 7 and Windows 8.1.Teredo (pronounced " ter-EE-do" )is named after the Teredo worm,which bores holes inwood.IPv6 addresses intended to be used by this protocol always begin with 2001 andthe prefix is written as 2001::/32.Teredo is enabled by default in Windows 7,but notWindows 8.1.On UNIX and Linux systems that don' t have Teredo installed by default,you can install third-party software such as Miredo to provide the Teredo service.
