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






3. 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.






4. Used to facilitate the resolution of single-label computer names in a large network.






5. The Zone Transfers tab also allows you to configure ______ to secondary servers whenever a change occurs at the primary zone.






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






7. ______ 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.






8. The no-refresh interval is the period after a time stamp during which a zone or server rejects a ______ refresh. The default no-refresh interval is 7 days.






9. When you do not store a zone in AD - the zone is called a ______ zone - and zone data is stored in text files on the DNS server.

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






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.






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