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.
1. The value you configure in the ______ text box determines how long a secondary server waits before retrying a failed zone transfer. Normally - this time is less than the refresh interval. The default value is 10 minutes.






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






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






4. Public key cryptography provides ______ - which means that separate keys are used to encrypt and decrypt data.






5. Increasing the refresh interval ______ zone transfer traffic.






6. What does the 10 refer to in the following example: _ldap._tcp SRV 0 0 389 dc1.lucernepublishing.com.SRV 10 0 389 dc2.lucernepublishing.com.






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






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






9. Manually created resource records for all zone types are assigned a time stamp of 0; this value indicates that they ______ be aged.






10. 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.






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

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






19. 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






20. TTL values are not relevant for resource records within their authoritative zones. Instead - the TTL refers to ______ in nonauthoritative servers. A DNS server that has cached a resource record from a previous query discards the record when that reco

22. Used to facilitate the resolution of single-label computer names in a large network.

24. 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.






25. Any of three events can ________________: When the refresh interval of the primary zone's SOA resource record expires - When a server hosting a secondary zone boots up - When a change occurs in the configuration of the primary zone and this primary






26. You must be a member of the ______ group to create an application directory partition.






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






28. 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.






29. The most common resource records you need to create manually include the following:






30. 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.






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






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






33. 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.

38. Together - aging and scavenging provide a mechanism to ______ resource records - which can accumulate in zone data over time. Both aging and scavenging are disabled by default.






39. 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






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