MCTS: Configuring A DNS Zone Infrastructure

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

3. ______ are public keys from other zones that are used to validate digitally signed records originating from those zones and from delegated subdomains that are also DNSSEC-compatible.






4. A ______ is a public key for a remote DNS server that is trusted and able to provide DNSSEC responses.






5. During this operation - the server hosting the local secondary zone determines whether the serial number in the secondary zone's SOA resource record has expired and then pulls a zone transfer from the master server.






6. The four options presented on the _____________________ are the following: 1. To All DNS Servers In This Forest 2. To All DNS Servers In This Domain 3. To All DCs In This Domain 4. To All DCs Specified In The Scope Of This Directory Partition

10. ______ in DNS refers to the process of using time stamps to track the age of dynamically registered resource records.

15. When you create a new zone - two types of records required for the zone are automatically created. List them.






16. This operation performs a zone transfer from the secondary zone's master server regardless of the serial number in the secondary zone's SOA resource record.






17. Active Directory-integrated zones perform time stamping for dynamically registered records by default - even before aging and scavenging are enabled. However - primary standard zones place time stamps on dynamically registered records in the zone onl

22. The ______ partition is replicated among all DCs that are also DNS servers in a particular domain






23. The Zone Transfers tab also allows you to configure ______ to secondary servers whenever a change occurs at the primary zone.






24. DNSSEC enables a DNS server to ______ the resource records in its zones.






25. This operation reloads the secondary zone from the local storage.






26. What kind of zones do not automatically perform time stamping on dynamically created resource records?






27. The ______ option stores the zone in the user-created application directory partition specified in the associated drop-down list box.

32. Scavenging can occur only when ______ is enabled.






33. The ___________________ dialog box enables you to modify two key settings related to aging and scavenging: 1. the no-refresh interval 2. and the refresh interval






34. To enable GlobalNames zone support - At an elevated command prompt - type the following: ______.






35. ______ zones provide a means to offload DNS query traffic in areas of the network where a zone is heavily queried and used.






36. The ______ allows you to specify the DNS query suffixes - prefixes - FQDNs - or reverse lookup subnets for which a Win 7 or Win Server 2008 R2 client will request DNSSEC.






37. A ______ zone provides original read-write source data that allows the local DNS server to answer DNS queries authoritatively about a portion of a DNS namespace.
