Which two parameters must be substituted to have the installer consume the answers in the install-answers file?

The correct parameters that must be substituted for the installer to consume the answers in the install-answers file are -A or -a. These parameters are specifically designed to instruct the installer on where to find the pre-defined answers, allowing for an automated installation process.

Using -A or -a signals to the installer to read from the install-answers file, ensuring that the installation proceeds with the configurations specified within that file. This is particularly useful in environments where automated deployments are preferred, as it minimizes the need for manual input during the installation process, thereby accelerating and streamlining the configuration.

In contrast, other parameters such as -b, -c, -x, -y, -m, and -n do not serve the purpose of linking the installer with the answers file. They might represent different functionalities or controls within the installation process, but they are not related to the consumption of an install-answers file. The focus on -A or -a highlights their specific role in enabling a seamless installation experience by leveraging pre-configured responses.
