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. 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.






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






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






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






5. The source zones from which secondary zones acquire their info are called ______ - and the data copy procedures through which this info is regularly updated are called zone transfers.






6. 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






7. 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






8. 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

12. 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






13. 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

17. 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.






18. 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.






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

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






24. 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

27. 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.






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






29. 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.






30. 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 ______.






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






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






33. A ______ is a database containing records that associate names with addresses for a defined portion of a DNS namespace.






34. 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.






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






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






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






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






39. The _____ option stores the zone in the domain partition. Every DC in the local domain will receive a copy of the zone - regardless of whether the DNS Server role is installed on that DC.






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






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






42. 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.
