[单项选择]our company has a main office and two branch offices. Domain controllers in the main office host an active directory-integrated zone. The DNS servers in the branch offices host a secondary for the zone. Each branch office has an application server. Users access the application server by using its fully qualified domain name. you need to ensure that users in the branch office can access their local application server even if the WAN links are down for three days. What should you do?（）
A. Increase the expires after setting to 4 days on the start of authority (SOA) record for the zone.
B. Increase the refresh interval setting 0 4 days on the start of authority (SOA) record for the zone.
C. Configure the zone aging / scavenging properties dialog box to enable scavenge state resource records, and set the refresh setting to 4 days.
D. Configure the zone aging / scavenging properties dialog box to enable scavenge state resource records, and set NO-refresh interval setting to 4 days.
[单项选择] your company has a main office and two branch offices. Domain controllers in the main office host an active directory-integrated zone. The DNS servers in the branch office host a secondary zone for the domain and use the main office DNS servers as their DNS master servers for the zone. The company adds a new branch office. You add a member server named branch3 and install the DNS service on the server. You configure a secondary zone for the domain. The zone transfer fails. You need to configure DNS to provide zone data to the DNS server in the new branch office. What should you do?（）
A. Run dnscmd using the zoneresetmasters option.
B. Run dnscmd by using the zoneresetsecondaries option.
C. Add the new DNS server to the zone transfers tab on one of the DNS servers in the main office.
D. Add the new DNS server to the DNSUpdateProxy global security group in active directory users and computers.
[单项选择] Your company has a main office and two branch offices that are connected by WAN links. The main office runs the DNS Server service on three domain controllers. The zone for your domain is configured as an Active Directory-integrated zone. Each branch office has a single member server that hosts a secondary zone for the domain. The DNS servers in the branch offices use the main office DNS server as the DNS Master server for the zone. You need to minimize DNS zone transfer traffic over the WAN links. What should you do？（）
A. Decrease the Retry Interval setting in the Start of Authority (SOA) record for the zone.
B. Decrease the Refresh Interval setting in the Start of Authority (SOA) record for the zone.
C. Increase the Refresh Interval setting in the Start of Authority (SOA) record for the zone.
D. Disable the netmask ordering option in the properties of the DNS Master server for the zone.
