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. ______ 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.






2. 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.






3. 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: _______.






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






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






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






7. To create a custom application directory partition - type the following command:






8. 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.






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






10. 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.






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






13. To configure notifications - click ______ on the Zone Transfers tab when zone transfers are enabled.






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






15. 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.






16. When the zone is stored in a file instead of AD - by default the primary zone file is named zone_name.dns - and this file is located in the ______ folder on the server.






17. 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






18. 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.






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






20. 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.






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






22. The GlobalNames zone is compatible only with DNS servers running ______. Therefore - it cannot replicate to servers running earlier versions of Windows Server.






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






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






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






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






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






28. 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.






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






30. What are the server requirements for storing a zone in AD?






31. 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.






32. 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.






33. 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.






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






35. 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 ______.






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






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






38. 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.






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






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






41. By default - zone transfers are ______ from any zone.






42. 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






43. To add an NS record - double-click any existing NS record in DNS Manager and add the server data to the ______ tab.






44. 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






45. To ______ a zone is to create a new zone for a subdomain within a DNS namespace and relinquish authority of that new zone.






46. 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.






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






48. 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.
