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






3. Scavenging can occur only when ______ is enabled.






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






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






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






7. 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: _______.






8. 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:






9. 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






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






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






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






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






14. 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.






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






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






17. 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.






18. 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.






19. 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






20. 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.






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






22. 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.






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






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






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






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






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






28. 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 ______.






29. 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.






30. ______ 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.






31. 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






32. 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.






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






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






35. 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.






36. Increasing the refresh interval ______ zone transfer traffic.






37. 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.






38. 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.






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






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