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. 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 ______.






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






3. 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.






4. 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.






5. 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






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






7. 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.






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






9. 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






10. 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.






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






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






13. 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:






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






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






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






17. 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.






18. ______ 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.






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






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






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






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






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






24. 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.






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






26. 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.






27. 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.






28. Scavenging can occur only when ______ is enabled.






29. 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






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






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






32. 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.






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






34. 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.






35. The GlobalNames zone is compatible only with DNS servers running ______. Therefore - it cannot replicate to servers running earlier versions of Windows Server.






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






37. 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






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






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