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. DNS delegations are automatically used to separate ______ in a single forest.






2. ______ zones provide a means to offload DNS query traffic in areas of the network where a zone is heavily queried and used.






3. By default - DCs include two application directory partitions reserved for DNS data: ______.






4. To ______ a zone is to create a new zone for a subdomain within a DNS namespace and relinquish authority of that new zone.






5. This operation performs a zone transfer from the secondary zone's master server regardless of the serial number in the secondary zone's SOA resource record.






6. The value you configure in the ______ text box determines the default Time to Live (TTL) that is applied to all resource records in the zone. The default value is one hour.






7. 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






8. 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.






9. 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.






10. A ______ is a database containing records that associate names with addresses for a defined portion of a DNS namespace.

18. To add an NS record - double-click any existing NS record in DNS Manager and add the server data to the ______ tab.






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






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

28. 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






29. 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.






30. The ______ partition is replicated among all DCs that are also DNS servers in every domain in an AD forest.
