Question 4.
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?

Answer: A

Question 5.
Your company has a server named Server1 that runs Windows Server 2008. Server1 runs the DHCP Server role and the DNS Server role. You also have a server named ServerCore that runs a Server Core installation of Windows Server 2008. 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.

Answer: A

Question 6.
Your company has a domain controller named Server1 that runs Windows Server 2008 and the DNS server role. A server named Server2 runs a custom application. You need to configure DNS to include the following parameters for the custom application:

B. Service Locator (SRV)
C. Canonical Name (CNAME)
D. Well-Known Service (WKS)

Answer: B

Question 7.
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 the DNS Master servers 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 offices 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.
