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






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






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






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






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






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






7. ______ 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.






8. Increasing the refresh interval ______ zone transfer traffic.






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






10. 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.






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






12. Scavenging can occur only when ______ is enabled.






13. 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






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






15. 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.






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






17. 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.






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






19. 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 ______.






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






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






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






25. 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






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






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






28. 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






29. 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: _______.






30. 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.






31. 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






32. The ______ partition is replicated among all DCs that are also DNS servers in every domain in an AD forest.






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






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






35. 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.






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






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






38. 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.






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






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






41. 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.






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.
