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 ______ allows you to specify the DNS query suffixes - prefixes - FQDNs - or reverse lookup subnets for which a Win 7 or Win Server 2008 R2 client will request DNSSEC.






2. ______ are public keys from other zones that are used to validate digitally signed records originating from those zones and from delegated subdomains that are also DNSSEC-compatible.






3. 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.






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

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






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






23. 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

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.






38. 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.






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