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.

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






5. 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.






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






7. Scavenging can occur only when ______ is enabled.






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






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






10. 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.






11. 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.






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

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






16. 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

18. 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.






19. 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






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

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






25. 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.
