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






2. 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.






3. For a delegation to be implemented - the parent zone must contain a _____ and an _____ (called a glue record) pointing to each authoritative server of the delegated domain.






4. 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






5. By default - zone transfers are ______ from any zone.






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






7. When you create a new zone - two types of records required for the zone are automatically created: ______






8. The ______ option stores the new zone in the ForestDnsZones partition. Every DC in the entire forest and on which the DNS Server role is installed will receive a copy of the zone.






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






10. For a DC to fall within the scope of such a directory partition - you must ______ that DC in the partition.

12. ______ 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.






13. The ______ partition is replicated among all DCs that are also DNS servers in a particular domain






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






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






16. 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






17. 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.






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






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

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






22. 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.






23. What are the server requirements for storing a zone in AD?






24. A ______ zone provides original read-write source data that allows the local DNS server to answer DNS queries authoritatively about a portion of a DNS namespace.






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






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






27. 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.






28. 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.






29. ______ in DNS refers to the process of using time stamps to track the age of dynamically registered resource records.






30. Scavenging can occur only when ______ is enabled.






31. TTL values are not relevant for resource records within their authoritative zones. Instead - the TTL refers to ______ in nonauthoritative servers. A DNS server that has cached a resource record from a previous query discards the record when that reco






32. 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.






33. Win 7 clients can be configured to request DNSSEC through the Name Resolution Policy Table (NRPT) in ______.
