Question 1

Explain the DHCP lease process.

Accepted Answer

The process by which a DHCP client requests IP configuration from a DHCP server involves several stages. First, the client sends a request (DHCPDISCOVER packet) to all hosts on the LAN. In reply, a DHCP server sends an offer (DHCPOFFER packet) that contains a potential IP configuration. The DHCP client then selects (accepts) the offer by sending a DHCPREQUEST packet to the associated DHCP server. Next, the DHCP server sends to the client an acknowledgment indicating the amount of time the client can use the IP configuration (DHCPACK packet). Finally, the client configures itself with the IP configuration. REJ: Please explore the section " The DHCP Lease Process" for more information.

Question 2

What is the use of group NetBIOS name records?

Accepted Answer

Group NetBIOS name records are used by legacy (pre-Windows 2000) systems to locate a Windows Server 2019 domain controller. Although these legacy systems are uncommon today, industrial and manufacturing machinery often have a very long useful life. The computers that operate this machinery may contain a legacy operating system that requires access to domain resources, such as shared printers and folders. In these cases, group NetBIOS name records can provide the location for the nearest domain controller. REJ: Please explore the section " Configuring a WINS Server" for more information.
