Microsoft 70-642 TS: Windows Server 2008 Network Infrastructure, Configuring Certification 36-40

36. 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 offices 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 Server server role 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 by 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.
Answer: C

37. Your company has a main office and a branch office. The main office has a domain controller named DC1 that hosts a DNS primary zone. The branch office has a DNS server named SRV1 that hosts a DNS secondary zone. All client computers are configured to use their local server for DNS resolution.
You change the IP address of an existing server named SRV2 in the main office.
You need to ensure that SRV1 reflects the change immediately.
What should you do?
A. Restart the DNS Server service on DC1.
B. Run the dnscmd command by using the /zonerefresh option on DC1.
C. Run the dnscmd command by using the /zonerefresh option on SRV1.
D. Set the refresh interval to 10 minutes on the Start of Authority (SOA) record.
Answer: C

38. Your company has a single Active Directory domain. The company has a main office and a branch office. Both the offices have domain controllers that run Active Directory-integrated DNS zones.
All client computers are configured to use the local domain controllers for DNS resolution. The domain controllers at the branch office location are configured as Read-Only Domain Controllers (RODC).
You change the IP address of an existing server named SRV2 in the main office.
You need the branch office DNS servers to reflect the change immediately.
What should you do?
A. Run the dnscmd /ZoneUpdateFromDs command on the branch office servers.
B. Run the dnscmd /ZoneUpdateFromDs command on a domain controller in the main office.
C. Change the domain controllers at the branch offices from RODCs to standard domain controllers.
D. Decrease the Minimum (default) TTL option to 15 minutes on the Start of Authority (SOA) record for the zone.
Answer: A

39. Your company has a single Active Directory domain.
The company has a main office and three branch offices. The domain controller in the main office runs Windows Server 2008 R2 and provides DNS for the main office and all of the branch offices. Each branch office contains a file server that runs Windows Server 2008 R2.
Users in the branch offices report that it takes a long time to access network resources. You confirm that there are no problems with WAN connectivity or bandwidth.
You need to ensure that users in the branch offices are able to access network resources as quickly as possible.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Configure a standard primary zone in each of the branch offices.
B. Configure forwarders that point to the DNS server in the main office.
C. Configure a secondary zone in each of the branch offices that uses the main office DNS server as a master.
D. Install DNS servers in each of the branch offices.
Answer: CD

40. Your company has a server named Server1 that runs Windows Server 2008 R2. Server1 runs the DHCP Server server role and the DNS Server server role. You also have a server named ServerCore that runs a Server Core installation of Windows Server 2008 R2.
All computers are configured to use only Server1 for DNS resolution. The IP address of Server1 is 192.168.0.1. The network interface on all the computers is named LAN.
Server1 is temporarily offline. A new DNS server named Server2 has been configured to use the IP address 192.168.0.254.
You need to configure ServerCore to use Server2 as the preferred DNS server and Server1 as the alternate DNS server.
What should you do?
A. Run the netsh interface ipv4 add dnsserver “LAN” static 192.168.0.254 index=1 command.
B. Run the netsh interface ipv4 set dnsserver “LAN” static 192.168.0.254 192.168.0.1 both command.
C. Run the netsh interface ipv4 set dnsserver “LAN” static 192.168.0.254 primary command and the netsh interface ipv4 set dnsserver “LAN” static 192.168.0.1 both command.
D. Run the netsh interface ipv4 set dnsserver “LAN” static 192.168.0.254 primary command and the netsh interface ipv4 add dnsserver “LAN” static 192.168.0.1 index=1 command.
