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. A secondary zone will not be recognized as a valid name server until it contains a valid copy of zone data. For the secondary zone to obtain this data - you must first ______ to that server.






2. By default - DCs include two application directory partitions reserved for DNS data: ______.






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






4. For a delegation to be implemented - the parent zone must contain a _____ and an _____ (called a glue record) pointing to each authoritative server of the delegated domain.






5. Increasing the refresh interval ______ zone transfer traffic.






6. Alias resource records are sometimes called canonical names (CNAME). These records allow you to ______ a single host.






7. 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






8. 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






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






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






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






12. 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






13. The refresh interval is the time after the no-refresh interval during which time stamp refreshes are ______ and resource records are not scavenged. The default refresh interval is 7 days.






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






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






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






17. 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.






18. Also recommended for use in the following scenarios: When a host specified in an A resource record in the same zone needs to be renamed - When a generic name for a well-known server such as www needs to resolve to a group of individual computers tha






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






20. ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






21. 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: _______.






22. 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.






23. There are three basic steps in _______________: 1. Enable GlobalNames zone support. 2. Create the GlobalNames zone. 3. Populate the GlobalNames zone.






24. The value you configure in the ______ text box determines how long a secondary DNS server waits before querying the master server for a zone renewal. The default value for this setting is 15 minutes.






25. 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.






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

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






31. 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






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






33. Scavenging can occur only when ______ is enabled.






34. 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.






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






36. 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.






37. 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.






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






39. 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.
