Final answer:
In a Windows Server 2019 without DHCP configured or a static IP, the machine would likely be assigned an APIPA address in the range of 169.254.0.1 to 169.254.255.254, not 127.0.0.1, 0.0.0.0, 192.168.1.100, or 10.0.0.1.
Step-by-step explanation:
If a Windows Server 2019 Desktop Experience is installed on a virtual machine that is not configured to use a DHCP server or it does not have a statically assigned IP address, it is most likely to be assigned an Automatic Private IP Addressing (APIPA) address. When the DHCP client can't reach a DHCP server, the Windows operating system assigns an automatic IP address in the range of 169.254.0.1 to 169.254.255.254. So, the correct answer is neither of the options given (a. 127.0.0.1, b. 0.0.0.0, c. 192.168.1.100, d. 10.0.0.1). Instead, you would see an IP address beginning with 169.254.x.x, where 'x' is specific to the instance.
Option a, 127.0.0.1, is known as the loopback address and is used for local testing on the computer itself. Option b, 0.0.0.0, is a non-routable meta-address used to denote an invalid, unknown, or non-applicable target. Options c and d, 192.168.1.100 and 10.0.0.1, are commonly used in private networks and typically assigned by a DHCP server or set manually; they are not automatically assigned in absence of DHCP.
