A Linux system administrator is working on a Debian$-$based system and needs to switch from using DHCP to a static IP configuration for the network interface named eth$0.$ The desired static IP configuration is as follows:

IP Address: $10\mathrm{.}10\mathrm{.}15\mathrm{.}10$

Subnet Mask: $255\mathrm{.}255\mathrm{.}255\mathrm{.}0$

Gateway: $10\mathrm{.}10\mathrm{.}15\mathrm{.}1$

DNS Server: $8\mathrm{.}8\mathrm{.}8\mathrm{.}8$

Which of the following actions should the administrator take to achieve this configuration?
