Configuring and Managing Network Services

Kaya is an administrator at Kelvin Computing. Benjamin, a user, wants to access a shared folder on SERVERA, so he uses the UNC \\servera\share to access the folder. His computer then sends out a broadcast to the network to resolve the name SERVERA. Because of the broadcast, all computers on the LAN interpret it and causes additional processing that interferes with other operations. What can Kaya do to avoid this additional overhead? a. Install a WINS server b. Restart the DNS Server c. Configure a default forwarder d. Configure a conditional forwarder

a. Install a WINS server

Christopher sets up multiple WINS servers in his organization and configures users' computers to use the WINS server. During testing, he attempts to access a folder called Share on the computer SERVERA. He enters the following statement into File Explorer: \\serverA\share. However, Christopher is unable to access the shared folder. What is the most likely reason for this issue? a. SERVERA does not have a NetBIOS name record on any WINS server. b. Christopher has not set up replication. c. The user computer is connect to the LAN but not to the Internet. d. The UNC syntax entered is incorrect and is missing arguments.

a. SERVERA does not have a NetBIOS name record on any WINS server.

Which of the following is the most likely cause for missing resource records in a secondary zone? a. Zone transfer issues b. An invalid entry in the DNS cache c. Zones that allow dynamic updates d. Manual DNS cache flushing

a. Zone transfer issues

Which of the following is true of WINS? a. It is enabled by default on all Windows Server systems. b. It can only resolve NetBIOS names to IPv4 addresses. c. If NetBIOS is enabled, a WINS server does not need to be installed on the network. d. If a computer is configured to use WINS, it resolves NetBIOS names using broadcasts.

b. It can only resolve NetBIOS names to IPv4 addresses.

Reno is facing some DNS server issues that he is unable to resolve using nslookup, DNS manager, and other general methods. He decides to use information from the DNS Server log to identify the issue. However, the information that was logged is insufficient to resolve the issue. Reno is able to identify the issue after enabling debug logging. What should Reno do next? a. Reno should permanently enable debug logging. b. Reno should turn off debug logging. c. Reno should delete all the log files. d. Reno should flush the DNS server cache.

b. Reno should turn off debug logging.

You are the administrator for an Active Directory domain and have been tasked with improving the response time for resolving DNS queries for resources in a second company-owned domain that does not use Active Directory. What type of zone can be used to accomplish this task with minimal overhead? a. A forward zone b. A reverse zone c. A stub zone d. A glue zone

c. A stub zone

Malia configures a primary zone on a DNS server to accept dynamic updates. Whenever a computer is added to the network, resource records for the computer are automatically created. For a computer, NX2001EY, Malia configures resource records manually. On the Zone Aging/Scavenging Properties window, she selects Scavenge stale resource records, sets the No-refresh interval to 14 days, and sets the Refresh interval to 14 days. She also enables automatic scavenging in the DNS server's properties. If Malia removes NX2001EY from the network, what is the most likely outcome in this scenario? a. The resource records for N2001EY will be deleted within 14 days. b. All the resource records for N2001EY will be made available for scavenging after 28 days. c. Some of the resource records for N2001EY will be made available for scavenging after 28 days. d. Malia will need to manually remove all the resource records for N20001EY.

c. Some of the resource records for N2001EY will be made available for scavenging after 28 days.

Michelle is configuring a DHCP server in her organization. When creating a new scope, she is prompted to enter the subnet delay. She chooses to enter a few milliseconds of delay. If true, which of the following would justify this choice? a. The network contains other DHCP servers that lease IP addresses. b. The organization contains computers with manually configured IP addresses. c. The organization contains DHCP relay agents in different locations. d. The network contains DHCP servers configured in a DHCP failover configuration.

c. The organization contains DHCP relay agents in different locations.

Tuyet types the following statement into File Explorer: \\serverA\Share1 . The NetBIOS name is resolved by a WINS server, and Tuyet is able to access the shared folder. After this interaction with the WINS server, Tuyet does not perform any other operations that requires her computer to interact with the WINS server for over a week. Which of the following is true of this scenario? a. The NetBIOS name is first broadcast over the LAN to all the computers. b. Tuyet is using a Windows XP computer or another legacy operating system. c. Tuyet's computer's name record will be deleted from the WINS server. d. The WINS server will automatically shut down because of inactivity.

c. Tuyet's computer's name record will be deleted from the WINS server.
