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






2. 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.






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

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






6. 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

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






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






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






11. To add an NS record - double-click any existing NS record in DNS Manager and add the server data to the ______ tab.






12. 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.






13. 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.






14. 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.






15. 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.






16. 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.






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






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

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






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






25. ______ 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.






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






27. 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.

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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






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






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






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






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






35. 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.






36. 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.
