Environment variables keep sensitive data like API keys outside source code, preventing accidental exposure in code repositories.Step 2: Evaluate other options
They do not speed up programs, do not encrypt data automatically, and changes usually require restart.Final Answer:
They keep sensitive data out of source code and version control -> Option CQuick Check:
Env vars protect sensitive data = true [OK]
Quick Trick: Env vars keep secrets out of code and repos [OK]
Common Mistakes:
- Thinking env vars encrypt data
- Assuming env vars improve performance
- Believing env vars update live without restart
