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






2. 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.






3. 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.






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






5. ______ 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.






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






7. 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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






9. 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.






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






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






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






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






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






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






16. 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.






17. 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.






18. You must be a member of the ______ group to create an application directory partition.






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






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






21. Scavenging can occur only when ______ is enabled.






22. 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.






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






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






25. 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






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






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






28. 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






29. 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.






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. DNS delegations are automatically used to separate ______ in a single forest.






32. Increasing the refresh interval ______ zone transfer traffic.






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






34. 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.






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






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






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






38. 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: _______.






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






40. 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.

42. 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.






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






44. The ______ option stores the new zone in the Domain-DnsZones partition. Every DC in the local domain and on which the DNS Server role is installed will receive a copy of the zone.
