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.

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






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






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






5. 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.






6. 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.






7. ______ 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.






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






9. 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 ______.






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






11. A ______ is a data structure in AD that distinguishes data for different replication purposes.






12. 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.






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






14. 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.






15. 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.






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






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






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






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






20. The ______ service uses SRV records to locate DCs in a domain by searching the domain for the LDAP service.






21. 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.






22. 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 ______.






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






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






25. Increasing the refresh interval ______ zone transfer traffic.






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






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






28. 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.






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






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






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






32. DNSSEC in Win Server 2008 R2 allows a ______ to validate DNS data on behalf of its Win 7 clients.






33. 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






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






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






36. 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






37. 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.






38. 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.






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






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






41. 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: _______.






42. 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.






43. 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.






44. 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.
