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.

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






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






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






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






6. 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






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






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






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






10. ______ 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.






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






12. 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






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






14. 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.






15. Increasing the refresh interval ______ zone transfer traffic.






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






17. 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

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






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






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






22. 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.






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






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






25. 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.






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






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






28. 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.






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






30. 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






31. 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.

33. 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.






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






35. 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.






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. 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






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






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






40. 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.






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






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






43. 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






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






45. 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.
