Difficulty: MediumApplication Installation and Configuration Concepts

An IT technician is deploying a specialized line-of-business application on a newly installed Windows 11 workstation. The application requires elevated administrative rights to install, requires network access on a custom service port, and saves shared database cache files to a central local directory for standard users. What is the correct sequence of steps the technician should perform from first to last to complete this installation and post-installation configuration?

  1. 1Verify system prerequisite compatibility, including OS architecture (64-bit) and required library dependencies.
  2. 2Execute the application setup installer using elevated administrator privileges.
  3. 3Configure NTFS permissions on the application data folder in C:\ProgramData to grant standard users Modify permissions.
  4. 4Create custom inbound and outbound traffic rules in Windows Defender Firewall for the application's network port.
  5. 5Log in under a standard user account to test application launch, network connectivity, and data persistence.

Answer

The correct sequence of steps is: 1) Verify system prerequisite compatibility, 2) Execute the application installer using elevated administrator privileges, 3) Configure NTFS permissions on the shared folder in C:\ProgramData, 4) Create custom inbound and outbound rules in Windows Defender Firewall, and 5) Log in under a standard user account to test functionality.
The correct deployment workflow follows established system administration standards: first verifying pre-installation system compatibility, then running the installer with elevated administrator rights to copy files to protected system locations. Following installation, post-install configurations are applied—adjusting NTFS permissions on shared directories (such as C:\ProgramData) so standard users can write data, and opening necessary network ports in Windows Defender Firewall. Finally, functional testing must occur under a standard user profile to confirm end-user operational capability.

Step-by-Step Solution

1
Perform pre-installation verification.
Confirms the host operating system meets minimum system requirements and architecture compatibility.
Checking prerequisites prevents installation failures or runtime crashes caused by incompatible OS bitness or missing software prerequisites.
2
Run the installer with elevated administrative rights.
Installs program binaries into protected system directories.
Standard users lack permission to modify protected system directories such as C:\Program Files.
3
Modify folder permissions in C:\ProgramData.
Grants the local Users group Modify NTFS permissions for the application folder.
Standard users cannot modify shared data in C:\ProgramData by default unless explicit write/modify permissions are granted.
4
Configure Windows Defender Firewall rules.
Opens specific network ports for the application's network communications.
Network traffic will be blocked by default unless firewall exception rules match the application's required ports.
5
Test operation using a non-administrative standard user profile.
Validates that standard users can run the application, connect to network services, and save data without UAC elevation prompts.
Testing under administrative profiles masks privilege and permission issues that end users will experience.
