Which of the following is not a benefit of using Docker?

The benefit that is not associated with using Docker is the existence of dependency conflicts. Docker is designed to encapsulate applications and their dependencies within containers, ensuring that they run consistently across different computing environments. This effectively mitigates the issue of dependency conflicts, which commonly arise when multiple applications require different versions of the same library or package.

By packaging applications with all their required dependencies into a container, Docker allows developers to avoid the typical complications of dependency management. This results in faster deployment, as the applications can be started on any system with Docker installed without worrying about whether the required dependencies are present or correctly configured.

The other options highlight significant benefits of Docker. For instance, faster deployment allows teams to move applications from development to production seamlessly. Easy scaling capabilities enable organizations to respond dynamically to changing loads by spinning up or down containers as needed. Consistent environments ensure that applications behave the same way in development, testing, and production, further streamlining the development process and reducing unexpected behaviors when an application is deployed.
