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. 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.






2. A ______ zone is similar to a secondary zone - but it contains only those resource records necessary to identify the authoritative DNS servers for the master zone.






3. The four options presented on the _____________________ are the following: 1. To All DNS Servers In This Forest 2. To All DNS Servers In This Domain 3. To All DCs In This Domain 4. To All DCs Specified In The Scope Of This Directory Partition

21. To configure notifications - click ______ on the Zone Transfers tab when zone transfers are enabled.






22. ______ 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.






23. ______ resource records are used to specify the location of specific services in a domain.
