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. Scavenging can occur only when ______ is enabled.






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






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






4. 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.






5. 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.






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






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






8. 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.






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






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






11. 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






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






13. 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.






14. 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.






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






16. 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.






17. 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.






18. 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: _______.






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






20. 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.






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






22. 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.






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

28. 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.






29. ______ 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.






30. 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 ______.






31. 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.






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






33. 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.






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






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






36. 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






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






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






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