Question

Your company experiences bugs, outages, and slowness in its production systems. Developers use the production environment for new feature development and bug fixes. Configuration and experiments are done in the production environment, causing outages for users. Testers use the production environment for load testing, which often slows the production systems. You need to redesign the environment to reduce the number of bugs and outages in production and to enable testers to toad test new features. What should you do?

Why each option

To resolve production issues caused by developing, experimenting, and testing in the production environment, redesign by establishing a dedicated development environment for code writing and a separate test environment for configurations, experiments, and load testing.

ACreate an automated testing script in production to detect failures as soon as they occur.

Automated testing in production is a detection and monitoring strategy, not a preventive measure against the root causes of issues stemming from misuse of the production environment for development and testing.

BCreate a development environment with smaller server capacity and give access only to

While creating a development environment is a step in the right direction, it's incomplete as it doesn't address the need for a separate environment for configurations, experiments, and load testing that currently cause production issues.

CSecure the production environment to ensure that developers can't change it and set up one

While securing production is good, consolidating all development, configuration, and testing into a *single* separate environment risks conflicts and instability, especially when load testing is performed alongside active development.

DCreate a development environment for writing code and a test environment for configurations,Correct

Creating distinct development and test environments isolates new feature development and testing (including load testing and experiments) from the production system, preventing configuration changes, testing loads, and development bugs from impacting users and ensuring production stability.
