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. To create a custom application directory partition - type the following command:






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






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






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






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






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






8. 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.






9. Increasing the refresh interval ______ zone transfer traffic.






10. 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






11. 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.






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






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






14. 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.






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






16. 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.






17. 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.






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






19. 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.






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. 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

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






24. 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.
