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 use Group Policy to configure DNS clients to _________________.






2. 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.






3. 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.






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






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






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






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






8. By right-clicking a secondary zone in the DNS Manager console tree - you can use the shortcut menu to perform the following secondary zone update operations:






9. 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.






10. The _____ option stores the zone in the domain partition. Every DC in the local domain will receive a copy of the zone - regardless of whether the DNS Server role is installed on that DC.






11. 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






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






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






14. 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






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






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






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






18. 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.






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






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






21. When you create a new zone - two types of records required for the zone are automatically created. List them.






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






23. 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. The value you configure in the ______ text box determines how long a secondary server waits before retrying a failed zone transfer. Normally - this time is less than the refresh interval. The default value is 10 minutes.






25. 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.






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






27. 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.






28. 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.






29. 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






30. 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.






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






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






33. 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.






34. 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.






35. What kind of zones do not automatically perform time stamping on dynamically created resource records?






36. The GlobalNames zone is compatible only with DNS servers running ______. Therefore - it cannot replicate to servers running earlier versions of Windows Server.
