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 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.






2. 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.






3. 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:






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






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

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






9. 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.






10. 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.






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






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






13. 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

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






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






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






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

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






24. 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






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






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

28. 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.






29. 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






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






31. 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.

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






34. 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

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

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






40. DNSSEC enables a DNS server to ______ the resource records in its zones.






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






42. Scavenging can occur only when ______ is enabled.






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