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. 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.






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






3. 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: _______.






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






5. 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.






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






7. To enable GlobalNames zone support - At an elevated command prompt - type the following: ______.






8. 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






9. 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.






10. 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.






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






12. You must be a member of the ______ group to create an application directory partition.






13. ______ 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.






14. 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 ______.






15. 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.






16. 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.






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






18. 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.






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






20. 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






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






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






23. 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






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






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






26. 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.

30. 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.






31. 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






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






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

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






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






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