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.

3. 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.






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






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






6. 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

8. 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






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.






10. 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.






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






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






13. 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.






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

17. 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.






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






19. 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.






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






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






22. 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.






23. 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.






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






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






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






27. 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.






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






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

31. 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:






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






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






34. 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.






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






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






37. 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






38. ______ 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.






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






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






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






42. 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.






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






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






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