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






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






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






5. 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






6. ______ 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.






7. 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






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






9. 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.

11. 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:

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






14. 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.






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






16. 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: _______.






17. 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.






18. A ______ is a database containing records that associate names with addresses for a defined portion of a DNS namespace.






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






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






21. If either of the default application directory partitions is deleted or damaged - you can re-create them in DNS Manager by right-clicking the server node and choosing ______.






22. Increasing the refresh interval ______ zone transfer traffic.






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






24. 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.






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






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






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






28. Scavenging can occur only when ______ is enabled.






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






30. 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.






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






32. 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.






33. 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.






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






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






36. 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.






37. 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






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