Question
A developer is testing a new application feature in isolation to avoid affecting the main system. What environment are they using?
A. Production environment
B. Sandbox environment
C. Development environment
D. Staging environment
E. Backup environment
Answer
B. Sandbox environment
Explanation
A sandbox environment isolates testing to prevent impact on the main system. Production runs live applications, development is for coding, staging mimics production, and backup stores data, none isolating tests like a sandbox.
A sandbox environment is a controlled, isolated setting designed specifically for testing new application features or code changes without affecting the main system or live production environment. This isolation ensures that any errors, bugs, or issues encountered during testing do not disrupt ongoing operations or compromise data integrity.
- Production environment: Used for live, operational applications accessed by end users. Testing here risks impacting real users and data.
- Development environment: Where developers write and initially test code, but it may not fully isolate changes from other ongoing development activities.
- Staging environment: Closely replicates production for final testing before deployment, but is not intended for isolated feature testing.
- Backup environment: Stores copies of data for recovery purposes and is not used for testing application features.
The sandbox environment is purpose-built for safe, isolated experimentation, making it the correct choice for testing new features without risk to the main system. This aligns with best practices and is a key concept for the CompTIA A+ Core 1 220-1101 exam.
