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






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






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. 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.






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






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. 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

12. ______ 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.






13. 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.

15. 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:






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






17. 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.






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






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






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






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






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






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






24. Increasing the refresh interval ______ zone transfer traffic.






25. 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.






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






27. 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.






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

32. 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.






33. 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

35. This operation reloads the secondary zone from the local storage.






36. 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.






37. 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.






38. To enlist other DNS servers in the partition - type the following command:
