Lesson 1

Lesson 1 1 For a computer to be accessible from the Internet, it must have an IP address that is both Registered and Uniqe. 2 A refferal is the process by which one DNS server sends a name resolution requests to another DNS server. 3The Internet Corpotation for Names and Numbers (ICANN)manages IANA, the ultimate source for all registered addresses. 4 IANA allocate blocks of addresses to Regional Internet Registries (RIR) which allocate smaller blocks in turn to Internet service provides (IPSs). Windows Server 2008 and Windows Server 2008 R2 include a new DNS feature called the Global Names Zone, Which can resolve single-label names like those used in the NetBIOS namespace. 6 A DNS server can function as a resolver, which simply provides name-resolution services to clients on the network. 7 Windows can use a variety of NetBIOS name-resolution machanisms, but the one most suited for the enterprise is the Windows Internet Names System (WINS). Toredo is an automatic tunneling protocol used by Windows workstation operating systems that are located behind NAT routers 9 A special type of DNS server specifically intended to send recursive queries to another server is called a forwarfer 10 The primary method for transmitting IPv6 traffic over an IPv4 network is called Tunneling TRUE/FALSE /F 1 Windows Server 2003 and Windows XP both include support for IPv6, and install it by default. /F 2 Push partnershops are preferable for WINS servers connected by slower links, such as WANconnections, because you can schedule replication to occur during off hours, when traffic is low. F 3 The IP standard included Class D, Which was reserved for experimental use, and Class E, which was reserved for use as multicast identifiers. T/ 4 Name resolution is the process of locating the IP address equivalent for a given name. T/ 5 Zone transfers are not necessary when you configure a primary zone to be stored in AD. F/ 6 If you have computers running Windows version prior to Windows 2000 on your network, then you must have a WINS server to provide NetBIOS name-resolution services.

T/ 7 T The ISATAP tunneling protocol incorporates the work station’s IPv4 address into the interface ID field of an IPv6address. T/ 8 Classless Inter-Domain Routing (CIDR) is a subneting method that enables administrators to place the division between the network bits and the host bits anywhere in the address, not just between octets. /F 9 In IPv6 link-local unicast addresses always begin with fd00 as the value of the first block. T/ 10 Using the same domain name for internal and external networks is usually not recommended, because it can make it difficult for internal users to access external resources
