A systems administrator is tasked with deploying a new server that will host a custom, resource-intensive, three-tier financial application. The application vendor has provided documentation that specifies the required version of the .NET Framework, a specific Java Runtime Environment (JRE), and several proprietary libraries that must be present. The server will connect to a separate, existing database server. To ensure the application installs and functions correctly, which of the following actions should the administrator perform FIRST?
Install all available OS updates and perform a full system security scan.
Install and configure all specified frameworks, runtimes, and libraries on the server.
Create dedicated disk partitions for application logs and implement storage quotas.
Configure the web server role (IIS/Apache) and create a default site with an SSL certificate.
The correct answer is to first install all specified frameworks, runtimes, and libraries. Application servers are defined by the applications they run, and their primary requirement is to provide the necessary environment for that software. The vendor's documentation explicitly lists these dependencies, and without them, the application installation will fail or the application will not run correctly.
Configuring the web server role is a plausible but incorrect next step. While the application may have a web front end, the underlying application logic and its dependencies must be in place first. Often, the application's own installer will configure the web server as needed. Creating dedicated partitions is a good practice for manageability and performance tuning but is not the most critical initial step to ensure the application can be installed. Installing OS updates is also a critical server administration task (baselining), but in the context of deploying a specific application with known dependencies, ensuring those dependencies are met is the immediate priority to guarantee functionality. Sometimes, an application may require a specific OS patch level, but installing all available updates without first installing prerequisites can lead to compatibility issues.
