You don't want to use a HomeGroup because even though it's five users, you need to make sure that permissions are set up properly so that users can't look at data of other users. Because they are never going to get any larger, there is no reason to have them use any version of Active Directory or Windows Server.

You are hired by a small company to set up a network. The company sells pocket watches and it has only five employees. It can't afford a server and client access licenses. What type of network can you set up for the company? A Create a HomeGroup. B Set up on Azure Active Directory. C Load Windows Server onto a Windows 10 system. D Set up all Windows 10 clients on a workgroup.

D By setting up a Stateful network Answer D is correct. You will do this by setting up a Stateful network. Stateful means that DHCP is going to give our IPv6 clients all of their TCP/IP data (IP address, default gateway, and all DHCP options). Answer A is incorrect. Stateless configuration means that the client's address is based on the router's advertisement messages. Clients create their IP address and default gateway based on the router's advertisement message and their MAC address. They can still get all of the other DHCP options, but they will not get an IP address and default gateway from DHCP. Answer B is incorrect. DNS is a name-resolution service that resolves a hostname to a TCP/IP address. Answer C is incorrect. APIPA is used to automatically assign private IP addresses for home or small business networks that contain a single subnet, have no DHCP server, and are not using static IP addressing.

You are the network administrator for a large organization that has decided to use IPv6 and DHCP.

B Tell them that without the new hardware, there is no way to install Active Directory. C Use Microsoft OneDrive to install Active Directory. D Install Active Directory on the UNIX system.

C By setting up a Stateful network Answer C is correct. You will set this up by using a Stateful network. Stateful means that DHCP is going to give our IPv6 clients all of their TCP/IP data (IP address, default gateway, and all DHCP options). Answer D is incorrect because Stateless configuration means that the clients' address is based on the router's advertisement messages. Clients create their own IP address and default gateway based on the router's advertisement message and their MAC address. They can still get all of the other DHCP options, but they will not get an IP address and default gateway from DHCP. Answer A is incorrect because a DNS server turns a hostname into an IP address. Answer B is incorrect because APIPA is used to automatically assign private IP addresses for home or small business networks that contain a single subnet, have no DHCP server, and are not using static IP addressing.
