You have a file server named srv3

http://csuglobal.blackboard.com/bbcswebdav/courses/KEY_ITS405/images/ITS405_MeMod04_Q09.jpg Refer to the graphic above to answer the following question. You are the administrator of the westsim.private domain. The data for the westsim.private zone is stored in Active Directory. You have just opened a branch office in Phoenix. The branch office is connected to the main offices with a slow WAN link. The WAN link is unreliable and is sometimes down for 3 days at a time. You plan on replacing the connection in the future, but for now the link will have to be used. You configure a secondary zone for westsim.private at the Phoenix location accepting the default configuration. The SOA record for the zone is shown in the graphic above. What change should you make to prevent name resolution problems at the Phoenix location?

Answer

Increase the Refresh interval to 3 days.

Decrease the Refresh interval value to 10 minutes.

Increase the Expires after value to 4 days.

Increase the Retry interval to 1 day.

Question 3

You are the network administrator for your company's network. Your network consists of 8 Windows 2008 Server computers, 500 Windows XP Professional computers, and 5 UNIX servers. One of your Windows 2008 Server computers is your DNS server. The DNS zone is configured as an Active Directory-integrated zone. The DNS zone is also configured to allow dynamic updates. Users report that although they can access the Windows XP computers by host name, but they cannot access the UNIX servers by host name. What should you do?

Answer

Manually enter A (host) records for the UNIX servers in the zone database.

On the DNS server, manually create a HOSTS file that contains the records for the UNIX servers.

Configure a UNIX computer to be a DNS server in a secondary zone.

Manually add the UNIX servers to the Windows domain.

Question 4

You are configuring the network for a new company with two sites: the main office is in Denver, and a branch office is in Phoenix. The sites are connected by a WAN link. All servers, including domain controllers, will run Windows Server 2008. All servers will be members of an Active Directory domain. The main office uses the domain of corp.westsim.com. All domain members are currently located only in the Denver location. The branch office uses the domain of research.corp.westsim.com. All domain members are located only in the Phoenix location. The following servers are in each location (Location, Server, Role): Denver, srv1.corp.westsim.com, Domain controller DNS server Denver, srv2.corp.westsim.com, Domain controller DNS server Denver, srv3.corp.westsim.com, Domain controller Phoenix, srv1.research.corp.westsim.com, Domain controller DNS server Phoenix, srv2.research.corp.westsim.com, Domain controller DNS server Phoenix, srv3.research.corp.westsim.com, Domain controller All zones are Active Directory integrated zones, and there are no other DNS servers on the network. To improve name resolution at the Phoenix location, you install a domain controller and DNS server named srv4.corp.westsim.com in the Phoenix location. You want this server to have a copy of the corp.westsim.com zone but not the research.corp.westsim.com zone. You do not want any servers in the Denver location to have a copy of the research.corp.westsim.com zone. You want to minimize DNS replication traffic where possible. What should you do? (Choose two. Each correct choice is part of the solution.)

Answer

Disable zone transfers on both zones.
