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 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.






2. 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.






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






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






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






6. 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.






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






8. 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






9. A ______ is a database containing records that associate names with addresses for a defined portion of a DNS namespace.






10. You use Group Policy to configure DNS clients to _________________.






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






12. 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.






13. 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.






14. 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.






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






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






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






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. 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.






20. 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.






21. 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.






22. 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






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






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






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






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






27. 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 ______.






28. 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.






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






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






31. To create a custom application directory partition - type the following command:






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






33. 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.






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






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






36. 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.






37. 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.






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






39. Scavenging can occur only when ______ is enabled.






40. 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.






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






42. 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: _______.






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