Windows 10 Pro is the most appropriate operating system for corporate desktops that require integration with an Active Directory domain and support for enterprise-level security features. It offers native support for domain joining, group policy management, and other advanced security features like BitLocker encryption, making it suitable for a centralized managed IT environment.

ext4 is the recommended filesystem for the Linux partition in a dual-boot setup with Windows and Ubuntu Linux. ext4 offers improved performance, reliability, and support for larger file sizes and volumes than its predecessors, making it the standard for Linux distributions. Unlike NTFS and FAT32, which are primarily used with Windows, and exFAT, designed for flash drives and external storage, ext4 provides journaling, which helps protect against data corruption in the event of a system crash.

XFS is the ideal filesystem for Linux servers that need to efficiently handle high-volume, transactional data operations. It is designed to offer excellent performance in managing large files and high-performance volumes, making it suitable for environments that require high levels of data integrity and scalability, such as database and web servers.

The iOS/iPadOS ecosystem provides a consistent experience across Apple’s desktop (macOS) and mobile devices (iOS for iPhone and iPadOS for iPad), including a seamless integration and similar user interfaces. While Android and Windows offer solutions for mobile and desktop environments, respectively, they do not provide as unified and consistent an experience across both types of devices as the Apple ecosystem does.

Ubuntu Linux is the most suitable operating system for a secure workstation environment that demands high stability, extended security updates beyond traditional EOL, and auditable source code. Linux distributions like Ubuntu offer long-term support (LTS) versions, community-driven security updates, and open-source code, which allows for thorough security audits and customizations to enhance security posture, meeting the analyst’s requirements.

Btrfs (B-tree filesystem) is the most appropriate choice for Linux servers in a mixed-use environment that requires support for snapshots for easy backup and recovery. Btrfs is designed to include features like snapshotting, self-healing data, and scalability, making it suitable for dynamic and high-availability environments.

NTFS should be used on laptops running Windows 10 to meet the requirement for full disk encryption as mandated by the organization’s security policy. NTFS supports BitLocker, which is Microsoft’s full disk encryption feature, providing strong data protection by encrypting the entire disk volume.

Windows 10 Pro best fits the requirements for a company transitioning to remote work. It offers built-in VPN support, robust security features including BitLocker and Windows Defender, and compatibility with a wide range of remote desktop solutions, making it well-suited for remote work environments.

Android is the most suitable OS for a developer aiming for cross-device application development. It runs on a wide range of devices from smartphones to tablets, offering a unified development environment across different hardware. iOS and iPadOS are more restricted to Apple devices, and while Windows has broad support, it does not match Android’s versatility in mobile application testing and development.

ext4 is recommended for forensic analysts requiring detailed transaction logs to track changes and ensure data integrity. It offers journaling features that log all transactions, making it possible to recover previous states of the filesystem and ensuring data integrity. While NTFS and APFS offer similar features, ext4 is widely used in Linux, which is commonly used in forensic environments for its robustness and transparency.

NTFS (New Technology File System) supports file-level encryption and security permissions, making it suitable for protecting sensitive data. Unlike FAT32 and exFAT, which lack these advanced features, and ext4, which is primarily used in Linux environments, NTFS provides comprehensive security measures such as encryption with BitLocker and access permissions, aligning with the company’s IT policy requirements for data protection.

NTFS is most suitable for handling large volumes of data and supporting large files, which is essential for video editing projects. It overcomes the file size and volume limitations associated with FAT32 and offers more robust features compared to exFAT and ext3, including security permissions, encryption, and journaling, thereby providing the reliability and performance needed for handling large video files.

Chrome OS is designed to be lightweight and is optimized for web browsing, making it the best choice for devices with minimal hardware resources. It runs web applications and cloud-based tools efficiently, unlike Windows 10 Pro and macOS, which are full-featured operating systems requiring more system resources. While Ubuntu Linux can also be lightweight, Chrome OS is specifically tailored for web-centric usage.

macOS is the preferred operating system for graphic designers who require optimized performance for creative software like Adobe Creative Suite. macOS is known for its robust support for creative software and peripherals, including drawing tablets, making it a popular choice among professionals in the graphic design industry.

APFS (Apple File System) is the most likely filesystem to be encountered on a hard drive from a macOS computer, especially if it is a recent model. APFS is optimized for solid-state drives (SSDs) and provides strong encryption, space sharing, and improved file integrity compared to its predecessor, HFS+.

Windows 10 Pro is the ideal choice for running both Docker containers and native Windows applications. It supports Docker for Windows, allowing developers to create, deploy, and run containers directly on Windows, and it naturally runs Windows applications. While macOS and Ubuntu Linux support Docker, they may not seamlessly run all native Windows applications without additional software.
