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. Increasing the refresh interval ______ zone transfer traffic.






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






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. 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

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






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






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

12. 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.






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






14. 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

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






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






18. By right-clicking a secondary zone in the DNS Manager console tree - you can use the shortcut menu to perform the following secondary zone update operations:






19. 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.






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






21. 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.






22. 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.

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






25. 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.






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






27. 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 ______.






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






29. 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.






30. 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.






31. You can perform a delegation only from a ________________.






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






33. 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






34. 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.






35. The ______ partition is replicated among all DCs that are also DNS servers in every domain in an AD forest.

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






39. 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






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






41. 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.






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






43. The ______ option stores the new zone in the ForestDnsZones partition. Every DC in the entire forest and on which the DNS Server role is installed will receive a copy of the zone.






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

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






48. 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.
