Which of the following are valid log levels in many logging frameworks? (Choose Two)

Question

Options

• ADEBUG
• BVERBOSE
• CINFO
• DTRACE

• A
  72% (18)
• B
  20% (5)
• D
  8% (2)

Explanation

DEBUG and INFO are two of the most universally supported log levels across logging frameworks like Log4j, Python's logging module, SLF4J, and Winston. DEBUG is used for detailed diagnostic output during development, while INFO captures general operational messages confirming the application is working as expected.

VERBOSE (B) is not a standard level in most major frameworks - it appears in some platform-specific tools (like Android's Logcat) but is not part of the common cross-framework standard. TRACE (D) is a valid level in many frameworks (typically finer-grained than DEBUG), but it was not included in the correct answers here, making it the trickier distractor - the question is testing whether you know the most universally recognized levels.

Memory tip: Think of the classic severity ladder - DEBUG → INFO → WARN → ERROR → FATAL. These five are the core levels you'll find in nearly every major logging framework. If you see VERBOSE or TRACE as options, treat them as "maybe valid in some frameworks" but not the safest universal picks.
