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. You must be a member of the ______ group to create an application directory partition.






2. 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.






3. Active Directory-integrated zones perform time stamping for dynamically registered records by default - even before aging and scavenging are enabled. However - primary standard zones place time stamps on dynamically registered records in the zone onl






4. The source zones from which secondary zones acquire their info are called ______ - and the data copy procedures through which this info is regularly updated are called zone transfers.






5. When scavenging is not enabled - you can perform manual scavenging in zones by right-clicking the server icon in the DNS Manager console tree and then choosing ______.






6. The value you configure in the ______ text box determines how long a secondary DNS server waits before querying the master server for a zone renewal. The default value for this setting is 15 minutes.






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






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






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

13. The value you configure in the ______ text box determines the length of time that a secondary server - without any contact with its master server - continues to answer queries from DNS clients. After this time elapses - the data is considered unrelia

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






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






17. The ___________________ dialog box enables you to modify two key settings related to aging and scavenging: 1. the no-refresh interval 2. and the refresh interval






18. 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






19. 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.






20. Manually created resource records for all zone types are assigned a time stamp of 0; this value indicates that they ______ be aged.






21. ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






22. There are three basic steps in _______________: 1. Enable GlobalNames zone support. 2. Create the GlobalNames zone. 3. Populate the GlobalNames zone.






23. DNSSEC in Win Server 2008 R2 allows a ______ to validate DNS data on behalf of its Win 7 clients.






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






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

29. A ______ is a data structure in AD that distinguishes data for different replication purposes.






30. 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.






31. 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.






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






33. 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.
