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






2. If either of the default application directory partitions is deleted or damaged - you can re-create them in DNS Manager by right-clicking the server node and choosing ______.






3. ______ 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.






4. 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.






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






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






7. The first step in preparing a zone for DNSSEC is to back up the current zone data. To back up a zone - type the following command at an elevated command prompt: _______.






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






9. Increasing the refresh interval ______ zone transfer traffic.






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






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






12. 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.






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






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






15. What does the 10 refer to in the following example: _ldap._tcp SRV 0 0 389 dc1.lucernepublishing.com.SRV 10 0 389 dc2.lucernepublishing.com.






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






17. 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 ______.






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






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






20. 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.






21. 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.






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






23. 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.






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






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






26. 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.






27. 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:






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






29. The Zone Transfers tab also allows you to configure ______ to secondary servers whenever a change occurs at the primary zone.






30. 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.






31. 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.






32. 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.






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






34. 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.






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






36. 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.

39. Scavenging can occur only when ______ is enabled.






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






41. 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.
