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 _____ 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.






2. 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.






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






4. The ______ option stores the zone in the user-created application directory partition specified in the associated drop-down list box.






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






6. 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.






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

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






13. ______ 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.
