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






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






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






4. Also recommended for use in the following scenarios: When a host specified in an A resource record in the same zone needs to be renamed - When a generic name for a well-known server such as www needs to resolve to a group of individual computers tha






5. 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.






6. Increasing the refresh interval ______ zone transfer traffic.






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






8. 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.






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






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






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

13. 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






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






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






16. 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






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






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






19. 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.






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






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

23. 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 ______.






24. 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.






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






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






27. 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.

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






31. 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.






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






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






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






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






36. 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.






37. 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.






38. 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






39. 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 ______.






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