* A network technician is planning a network scope means that the technician is defining the range of IP addresses that can be assigned to the devices on the network.
* The web server needs to be within 12.31 69.1 to 12.31.69.29 means that the web server must have an IP address that falls within this range, which is a subset of the network scope.
* A range reservation is a feature of DHCP that allows the technician to reserve a specific range of IP addresses for a certain type of device, such as a web server, and prevent other devices from using those addresses. This ensures that the web server will always have an IP address within the desired range and avoid IP conflicts with other devices.
* A range reservation would meet this requirement, as the technician can configure the DHCP server to reserve the range of 12.31 69.1 to 12.31.69.29 for the web server and assign it an IP address from that range.
* The other options are not correct because:
* Lease time is the duration for which a DHCP server assigns an IP address to a device, not a way to specify a range of IP addresses.
* DNS is a service that resolves domain names to IP addresses, not a way to define a network scope or reserve a range of IP addresses.
* Superscope is a feature of DHCP that allows the technician to combine multiple scopes into one logical scope, not a way to restrict a range of IP addresses for a specific device.
