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






2. 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.






3. 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.






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






5. 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 ______.






6. Increasing the refresh interval ______ zone transfer traffic.






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






8. 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.






9. ______ in DNS refers to the process of using time stamps to track the age of dynamically registered resource records.






10. 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.






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






12. 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






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






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






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






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






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






18. 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






19. 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.






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






21. ______ 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.






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






23. 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






24. To configure notifications - click ______ on the Zone Transfers tab when zone transfers are enabled.






25. 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.






26. 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.






27. 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.






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






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






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






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






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

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






36. 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.

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






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






40. 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 ______.






41. 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.






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