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






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






3. 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.






4. 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.






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






6. 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






7. 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






8. The ___________________ dialog box enables you to modify two key settings related to aging and scavenging: 1. the no-refresh interval 2. and the refresh interval






9. Win 7 clients can be configured to request DNSSEC through the Name Resolution Policy Table (NRPT) in ______.






10. 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 ______.






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






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






13. 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.






14. 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.






15. 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.






16. 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.






17. 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.






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






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






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






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






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






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






24. 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.






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. 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: _______.






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






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






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






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






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.






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






33. 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 ______.






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






35. 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






36. 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.






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






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






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






40. By right-clicking a secondary zone in the DNS Manager console tree - you can use the shortcut menu to perform the following secondary zone update operations:






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






42. Scavenging can occur only when ______ is enabled.






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






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






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






46. 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.






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






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






49. Increasing the refresh interval ______ zone transfer traffic.
