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 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






2. 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.






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






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






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






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






7. 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.






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






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






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






11. 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.






12. 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.






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






14. 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






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






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

18. 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.






19. 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.






20. 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.






21. 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.






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






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






24. 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.






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

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






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






29. 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.






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






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

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

39. 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
