CompTIA Data+ DA0-002 (V2) Practice Question

The correct answer is containerization. Containerization is a technology that packages an application with all of its dependencies, such as libraries and configuration files, into a single, isolated unit called a container. This ensures that the application runs reliably and consistently when moved from one computing environment to another, such as from the analyst's laptop to a colleague's machine, which directly solves the problem of library version conflicts.

• A virtual machine (VM) also provides an isolated environment but does so by virtualizing the entire hardware stack, including a full guest operating system. This makes VMs much more resource-intensive and slower to start than containers, which only virtualize the operating system and share the host kernel. For packaging a single application and its dependencies, containerization is the more lightweight and efficient solution.
• A shared file system allows multiple users to access the same files but does not manage the software environment or dependencies needed to run a script. The library conflicts would still occur.
• A cloud data lakehouse is a data storage architecture that combines the features of a data lake and a data warehouse. It is used for storing and analyzing large amounts of data, not for packaging application execution environments.
