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. 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.






2. The four options presented on the _____________________ are the following: 1. To All DNS Servers In This Forest 2. To All DNS Servers In This Domain 3. To All DCs In This Domain 4. To All DCs Specified In The Scope Of This Directory Partition






3. 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






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






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






7. 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.






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






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






10. 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: _______.






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






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






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






14. 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.






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






16. 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.






17. 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.






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






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






20. 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.






21. 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.






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






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






24. ______ 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.






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






26. 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.






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






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






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






30. 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.






31. 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.






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






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






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






35. Scavenging can occur only when ______ is enabled.






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






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






38. 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:






39. 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.






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






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






42. 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






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






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






45. 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.






46. 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






47. 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 ______.
