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. 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






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






4. ______ 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.






5. 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.






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






7. 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:






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






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






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






11. 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 ______.






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






13. 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.






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






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






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. 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






18. 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.






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






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






21. 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.






22. 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.






23. 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.






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






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






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






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






28. 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.






29. 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.






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






31. 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.






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






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






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






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






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






37. 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.
