Answers to Exam Prep Questions

  1. C. To change the zone type, right-click the zone within the DNS management console and click Properties. In the Properties dialog box, make sure the General tab is selected and click the Change button beside the zone type. Select the option to store the zone within Active Directory. Answer A is incorrect because the zone type is configured at the zone level. Answers B and D are incorrect because there is no Zone Type tab available in either the server's Properties dialog box or the zone's Properties dialog box. There is also no option known as Active Directory Integrated.

  2. D. Mail servers are identified within a zone file using Mail Exchanger (MX) records. Answer A is incorrect because PTR records are used to associate an IP address with its hostname. Answer B is incorrect because A records are used to map hostnames to IP addresses. Answer C is incorrect because CNAME records are used to assign alias names to those names that are already referenced in another record.

  3. A. The new server should be configured as a secondary server. It will then maintain a copy of the DNS zone file. If the original DNS server goes offline, name resolution can still occur. Answer B is incorrect because master name servers are the source of the zone file for secondary servers. Answer C is incorrect because caching-only servers do not hold any zone information. Answer D is incorrect. A DNS forwarder is not a specific DNS role. When a DNS server is configured as a forwarder, it can forward requests that it cannot resolve to a specific DNS server.

  4. D. By configuring caching-only servers within each location, you can decrease the name resolution response time for users. Because the caching-only servers do not maintain any zone information, no traffic is generated from zone transfers. Therefore, answers A, B, and C are incorrect.

  5. C. If the hostname cannot be resolved using the NSLookup command, adding a PTR to the zone file will allow you to resolve the IP address to a hostname. Answer B is incorrect because Wrk02 is not the hostname being resolved. Answers A and B are incorrect because A records are used to map hostnames to IP addresses, not vice versa.

  6. C. By executing the ipconfig/flushdns command, you can delete the contents of the client resolver cache on the client computer. Although uninstalling the service would clear the contents of the cache, it's not the easiest way to perform the task; therefore, answer A is incorrect. Answer B is incorrect because deleting the file will completely remove it. Answer D is incorrect because this option is used to clear the contents of the cache file on the DNS server. However, the problem is not affecting any other DNS clients, which indicates that the problem likely resides with the cache on the DNS client.

  7. B. If the support tools have been installed, you can use Replication Monitor to ensure that replication between DNS servers is occurring on a regular basis. Answer A is incorrect because System Monitor is used to monitor the real-time performance of a DNS server. Answer C is incorrect because the DNS management console is used to configure and manage a DNS server but cannot be used to monitor DNS replication. Answer D is incorrect. DNS debug logging is used to collect detailed information about how a DNS server is operating.

  8. C. The Secure Only option is available only if the DNS service is installed on a domain controller. Therefore, answers A, B, and D are incorrect. Answer A is incorrect because this would not make the Secure Updates option unavailable. Answer B is incorrect because dynamic updates are performed when a computer or server updates resource records. Answer D is incorrect because primary and stub zones can be configured for secure updates.

  9. B. By configuring an authoritative DNS server within bayside.net to host a stub zone for the sales.bayside.net zone, any updates made to the authoritative name server resource records will be updated within the parent zone as well. None of the other options provided remedy this scenario effectively; therefore, answers A, C, and D are incorrect.

  10. B. To increase the rate at which the secondary server polls for updates, select the Start of Authority (SOA) tab from the zone's Properties dialog box and increase the refresh interval. Answer A is incorrect because the interval at which a secondary server polls for updates is configured at the zone level. Answer C is incorrect because the retry interval defines how often the secondary server continues to poll if the server does not respond. Answer D is incorrect because you must configure the refresh interval, and it must be done from the Start of Authority (SOA) tab.

  11. D. If a root DNS zone exists on the DNS server, you will not be able to configure a DNS forwarder. You must delete this file before you can proceed. Answer A is incorrect because you do not need to be a member of the Enterprise Admins group to manage a DNS server. Answer B is incorrect because changing the DNS role of the server will not determine whether the DNS server can be a forwarder. Answer C is incorrect because the round robin feature is used to load balance queries across multiple DNS servers.

  12. C. You should open the properties window for the DNS server called DNS01. Select the Forwarders tab and configure the DNS server to forward any name resolution requests for hostnames in the nwtraders.com domain to DNS02. Answers A and D are incorrect because DNS forwarders are not configured at the zone level. Forwarding must be configured at the server level. Answer B is incorrect because all name resolution requests should not be forwarded to DNS02. Only those requests for hostnames in the nwtraders.com domain should be forwarded to this server.

  13. The correct answer is Enable Round Robin. By selecting this option, the DNS server will be able to distribute queries across the web servers. It does so by rotating the list of web servers so a different web server is returned to a client.

  14. B. You should enable the BIND secondaries option on DNS-01. When this option is enabled, the Windows Server 2003 DNS server will not perform fast zone transfers because it is not supported by versions of BIND older than 4.9.4. Answer A is incorrect. This feature is disabled by default. Answers C and D are incorrect because this feature must be enabled on the Windows Server 2003 DNS server, not on the BIND DNS server.

  15. C. You should update the SRV record. The SRV record identifies services that are running on a host, the port used by the service, and the protocol. You should not update the Host (A) record. This record identifies the IP address assigned to a host. Answer B is incorrect because an Alias (CNAME) record specifies another DNS domain name for a name that is already referenced in another resource record. Answer D is incorrect because a Well Known Service (WKS) record identifies services running on a host by the service name, not the port number.

  16. D. To allow hosts on other subnets to resolve the NetBIOS names of the UNIX servers, static mapping must be configured because the UNIX servers are unable to register their NetBIOS records dynamically. Answers A and C are incorrect because performing these tasks does not allow hosts to resolve the NetBIOS names of the UNIX servers. Answer B is incorrect because if the clients can already resolve the names of hosts on other subnets, replication is already configured between the WINS servers.

  17. B. To allow B-Node broadcasts to be resolved across the network, a WINS proxy agent must be configured. The WINS proxy listens for B-Node broadcasts and contacts the WINS servers on the other subnets to resolve the name resolution request on behalf of the non-WINS client. Therefore, answers A, C, and D are incorrect.
