25
25. You are configuring two DHCP servers to provide fault tolerance to the 172.24.43.x subnet. You have placed two DHCP servers, one on the local subnet and the other one at the corporate office. You configure the scope of the first DHCP server to be 172.24.43.1-172.24.43.199. What should the scope of the second DHCP server be? a) 172.24.43.1-172.24.43.254 b) 172.24.43.1-172.24.43.199 c) 172.24.43.200-172.24.43.254 d) 172.24.43.255

26
26. You have two DNS domains, contoso.com and NY.contoso.com. You have the standard primary DNS servers for both domains located at the corporate office in San Francisco. If the WAN links fails between San Francisco and New York, how can you ensure that users can still resolve the DNS entries in NY to IP addresses? a) Create a standard primary DNS server for both domains in New York. b) Create a standard secondary zone for both domains in New York. c) Enable the DNS cache on the router for both domains in New York. d) Create an Active Directory integrated stub zone for both domains in New York.
b) Create a standard secondary zone for both domains in New York.
27

28
28. Which type of query receives the name resolution request and takes full responsibility for resolving the name? a) iterative b) recursive c) replication d) notification
