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.

2. 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.






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






4. 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 ______.






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






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






7. 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.






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






9. 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






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






11. 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.






12. The no-refresh interval is the period after a time stamp during which a zone or server rejects a ______ refresh. The default no-refresh interval is 7 days.






13. 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:






14. The four options presented on the _____________________ are the following: 1. To All DNS Servers In This Forest 2. To All DNS Servers In This Domain 3. To All DCs In This Domain 4. To All DCs Specified In The Scope Of This Directory Partition






15. 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






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






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. Increasing the refresh interval ______ zone transfer traffic.






19. 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.






20. 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.






21. 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.






22. 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






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






24. 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.






25. ______ 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.






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






27. You use Group Policy to configure DNS clients to _________________.






28. 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






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






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

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






33. A ______ is a public key for a remote DNS server that is trusted and able to provide DNSSEC responses.






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






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






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






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






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






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






40. Scavenging can occur only when ______ is enabled.






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






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






43. 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.






44. 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.






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






46. The _____ option stores the zone in the domain partition. Every DC in the local domain will receive a copy of the zone - regardless of whether the DNS Server role is installed on that DC.






47. 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.
