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.

9. 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.






10. Consequently - when aging is enabled - dynamically registered resource records can be scavenged after ___ days by default.

13. 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






14. When scavenging is not enabled - you can perform manual scavenging in zones by right-clicking the server icon in the DNS Manager console tree and then choosing ______.






15. The value you configure in the ______ text box determines the length of time that a secondary server - without any contact with its master server - continues to answer queries from DNS clients. After this time elapses - the data is considered unrelia






16. The source zones from which secondary zones acquire their info are called ______ - and the data copy procedures through which this info is regularly updated are called zone transfers.






17. A ______ is a data structure in AD that distinguishes data for different replication purposes.

20. When you create a new zone - two types of records required for the zone are automatically created: ______






21. A ______ zone is similar to a secondary zone - but it contains only those resource records necessary to identify the authoritative DNS servers for the master zone.






22. The value you configure in the ______ text box determines the default Time to Live (TTL) that is applied to all resource records in the zone. The default value is one hour.






23. ______ 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.






24. What is the name of the record that contains a hash of the public key in a delegated subdomain?






25. The first step in preparing a zone for DNSSEC is to back up the current zone data. To back up a zone - type the following command at an elevated command prompt: _______.

27. The ______ option stores the new zone in the Domain-DnsZones partition. Every DC in the local domain and on which the DNS Server role is installed will receive a copy of the zone.






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






29. The ______ service uses SRV records to locate DCs in a domain by searching the domain for the LDAP service.






30. Win 7 clients can be configured to request DNSSEC through the Name Resolution Policy Table (NRPT) in ______.






31. 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






32. ______ resource records are used to specify the location of specific services in a domain.






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






34. For a DC to fall within the scope of such a directory partition - you must ______ that DC in the partition.






35. To enlist other DNS servers in the partition - type the following command:






36. To enable aging for a particular zone - you have to enable this feature both at the ______ level.






37. In this way - digital signatures use ______ cryptography to prove that information is unspoofed and unchanged.






38. When you do not store a zone in AD - the zone is called a ______ zone - and zone data is stored in text files on the DNS server.






39. DNSSEC in Win Server 2008 R2 allows a ______ to validate DNS data on behalf of its Win 7 clients.






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