Which of the following best describes DNS? (Choose all that apply.)

Which of the following accurately represents an FQDN?

A DNS server that can't resolve a query from its local data sends a recursive query to a root server. True or False?

A resource record containing an alias for another record is which of the following record types?

What type of resource record is necessary to get a positive response from the command nslookup 192.168.100.10?

You re scanning the local cache on a DNS client, and you come across the notation ::1. What does it mean?

Your company just opened a small branch office where 10 computer users will work. You have installed a single Windows Server 2012 R2 computer configured as a member server for basic file and print server needs. Users require DNS for Internet access and to resolve names of company resources. You decide to install DNS on the existing server. Which of the following types of installations makes the most sense?

You have a DNS server outside your corporate firewall that s a stand-alone Windows Server 2012 R2 server. It hosts a primary zone for your public Internet domain name, which is different from your internal Active Directory domain names. You want one or more of your internal servers to be able to handle DNS queries for your public domain and to serve as a backup for the primary DNS server outside the firewall. Which configuration should you choose for internal DNS servers?

DNS ServerA forwards a query to ForwarderB, which replies with a not found message. DNS ServerA continues the lookup by querying a root server. True or False?

Which of the following is true about stub zones? (Choose all that apply.)

You have Windows Server 2012 R2 DNS servers, Windows Server 2008 DNS servers, and two old Windows 2000 DNS servers in a Windows domain. You just created a new zone, newzone.com, that you want replicated by Active Directory to all DNS servers. Where should you store the zone?

The DNS server at your headquarters holds a standard primary zone for the abc.com domain. A branch office connected by a slow WAN link holds a secondary zone for abc.com. Updates to the zone aren t frequent. How can you decrease the amount of WAN traffic caused by the secondary zone checking for zone updates?

When a DNS server responds to a query with a list of name servers, what is the response called?

What type of record does DNS create automatically to resolve the FQDN of an NS record?

You want a DNS server to handle queries for a domain with a standard primary zone hosted on another DNS server, and you don t want the server to be authoritative for that zone. How should you configure the server? (Choose all that apply.)

You re in charge of a standard primary zone for a large network with frequent changes to the DNS database. You want changes to the zone to be transmitted as quickly as possible to all secondary servers. What should you configure and on which server?

You have several hundred client computers using WINS to resolve names of some enterprise servers. Many of the client computers are laptops used to connect to the network remotely. You re trying to eliminate WINS from your network to reduce the number of protocols and services you must support. What can you do, with the least administrative effort, that allows you to stop using WINS yet still allows clients computers to use a single-label name for accessing enterprise servers?

You manage the DNS structure on your network. The network security group has decided that only one DNS server should contact the Internet. Under no circumstances should other servers contact the Internet for DNS queries, even if the designated server is down. You have decided that the DNS server named DNS-Int should be the server allowed to contact the Internet. How should you configure your DNS structure to accommodate these requirements?

You have a zone containing two A records for the same hostname, but each A record has a different IP address configured. The host records point to two servers hosting a high-traffic Web site, and you want the servers to share the load. After some testing, you find that you re always accessing the same Web server, so load sharing isn t occurring. What can you do to solve the problem?

You want to verify whether a PTR record exists for the server1.csmtech.local host, but you don t know the server s IP address. Which of the following commands should you use to see whether a PTR record exists for server1.csmtech.local?

You have two DCs, each with three Active Directory integrated zones. You re getting inconsistent DNS lookup results and suspect a problem with Active Directory replication. What tool can you use to investigate the problem? (Choose all that apply.)

To resolve a query, a DNS server looks in its local cache first. True or False?

You have just finished setting up your DNS infrastructure, and the DNS process seems to be working well. You want to be able to create a baseline of performance data so that if slowdowns occur later, you have information for comparison purposes. Which tool should you use?

You re having trouble with logons and other domain operations in your domain named csmtech.local. You want to verify that your domain clients can find domain controllers. Which of the following can you do? (Choose all that apply.)

Which is the correct order in which a DNS client tries to resolve a name?
