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






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






4. 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






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






6. 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.






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






8. 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.






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






10. The no-refresh interval is the period after a time stamp during which a zone or server rejects a ______ refresh. The default no-refresh interval is 7 days.






11. 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.






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






13. 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 ______.






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






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






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






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






18. 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






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






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






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






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






23. 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.






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






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






26. 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






27. 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.






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






29. 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.






30. 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.






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






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






33. 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.






34. ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






35. 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.






36. ______ 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.






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






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