You are a network administrator for Litware, Inc. The company’s main office is located in Lima, and branch offices are located in five other cities. The network consists of a single DNS domain named litwareinc.com. The network configuration is shown in the exhibit. (Click the Exhibit button.)

All network servers run Windows Server 2003. All client computer IP addresses are assigned by using a DHCP server that is located in each office. Client computers are reimaged often and are assigned new names each time they are reimaged. All client computers are configured to reference their local DNS server as the preferred DNS server and to reference the central DNS server as the alternate DNS server.A primary zone for litwareinc.com is configured on a server in the Lima office. Secondary zones are configured on a server in each branch office. The retry interval, the refresh interval, the expiration interval, and the default minimum Time to Live (TTL) interval are configured with the default settings.Network bandwidth utilization averages 40 percent. The network connection between the Lima office and the Bogota office fails an average of twice per day.Users in the Bogota office occasionally receive incorrect responses to queries against the local DNS server when the network connection is interrupted during a zone transfer. 
You need to change the configuration of the start of authority (SOA) resource record for litwareinc.com. In addition, you need to reduce the possibility that users can query local DNS zones before successful zone transfers occur.  
What should you do?()

A.Change the retry interval to 12 hours.
B.Change the default minimum Time to Live(TTL) to 2 days.
C.Change the refresh interval to 2 days.
D.Change the expiration interval to 12 hours.
