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






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






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






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






5. To enlist other DNS servers in the partition - type the following command:






6. The most common resource records you need to create manually include the following:






7. 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.






8. 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






9. ______ 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.






10. 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






11. 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






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






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






14. You can perform a delegation only from a ________________.






15. 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.






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






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






18. This operation reloads the secondary zone from the local storage.






19. To enable GlobalNames zone support - At an elevated command prompt - type the following: ______.






20. Scavenging can occur only when ______ is enabled.






21. 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.






22. 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.






23. 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.






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






25. To enable aging for a particular zone - you have to enable this feature both at the ______ level.






26. 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.






27. 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.






28. DNSSEC enables a DNS server to ______ the resource records in its zones.






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






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






31. Increasing the refresh interval ______ zone transfer traffic.






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






33. In this way - digital signatures use ______ cryptography to prove that information is unspoofed and unchanged.






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






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






36. 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.






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






38. 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.






39. When the zone is stored in a file instead of AD - by default the primary zone file is named zone_name.dns - and this file is located in the ______ folder on the server.






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






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






42. 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.






43. 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.






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