The left and right arrows are indicators of which type of deployment?

The left and right arrows represent the concept of moving changes or components between different environments in a deployment process. Specifically, they indicate promotion, where changes are moved from a lower environment to a higher one, such as from development to production, and back-promotion, which allows for changes to be reverted from production back to a development or lower environment. This two-way movement is essential for managing releases and making necessary adjustments as part of the deployment strategy.

In this context, the choice that correctly identifies the role of the left and right arrows as representations of the actions taken during a deployment process is promotion and back-promotion. This understanding highlights the significant aspect of managing changes effectively within a continuous integration/continuous deployment (CI/CD) pipeline.
