Unit 1 Assignment 1 Windows 2008 Network Services

Unit 1 Assignment 1 Windows 2008 Network function If you run through a routed local anesthetic airfield network and high-speed link up that argon fairly reli satisfactory, you might be able to use one DNS innkeeper for a larger, doubled sub-netted network bea. If you abide a high heel of client nodes on a wholeness subnet design, you might ask to add more than one DNS host to the subnet to provide backup and failover if the preferred DNS innkeeper stops responding.When determining the cast of DNS innkeepers you pick up to use, rate the effect of district impartings and DNS call into question traffic on slower cogitate in your network. Although DNS is designed to help quash broadcast traffic between local subnets, it does create some traffic between hosts and clients that should be reviewed, particularly when utilize in complexly routed LAN or crazy environments. Consider the effects of zone transfer over slower speed links, wish those typically used for a coarse area network (WAN) connection.Windows 7 declare Your UnderstandingAlthough the DNS Server serve up supports incremental zone transfers and DNS clients and servers can cache recently used names, traffic considerations are sometimes subdued an issue, particularly when DHCP leases are shortened and, as a result, dynamic updates in DNS are performed more frequently. One option for transaction with remote locations on WAN links is to set up a DNS server at these locations to provide caching-only DNS service. With most installations, you should have at least two server computers hosting each of your DNS zones for fault tolerance.DNS was designed to have two servers for each zone, one as a primary server and the other as a backup or secondary server. When making any final examination determinations about the number of servers to use, first assess the level of fault tolerance you desire for your network. Because there is no fixed determine to the maximum number of clients a D HCP server can service or to the number of scopes you can create on a DHCP server, the primary factors to consider when you determine the number of DHCP servers to use are network architecture and server hardware.For example, in a single subnet environment, only one DHCP server is necessary, although you whitethorn want to use two servers or deploy a DHCP server forgather for increased fault tolerance. In multiple subnet environments, routers must forward DHCP messages between subnets, so router performance can affect your DHCP service. In both cases, DHCP server hardware affects service to clients.
