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






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

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






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

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






34. 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






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






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






37. 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.
