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






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






3. 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.






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






5. ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






6. 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.






7. 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






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

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






11. 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.






12. ______ 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.






13. To add an NS record - double-click any existing NS record in DNS Manager and add the server data to the ______ tab.






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






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






16. 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.






17. 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






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






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






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






21. 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.






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






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






24. Increasing the refresh interval ______ zone transfer traffic.






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






26. 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.






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






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






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. Scavenging can occur only when ______ is enabled.






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






32. When you create a new zone - two types of records required for the zone are automatically created: ______






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






34. The four options presented on the _____________________ are the following: 1. To All DNS Servers In This Forest 2. To All DNS Servers In This Domain 3. To All DCs In This Domain 4. To All DCs Specified In The Scope Of This Directory Partition






35. 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.






36. 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.






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






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






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






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






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






42. 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






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