3 traps. 20% of your score. Let's defuse them.
Domain 3 (Prompt Engineering and Claude Code) is worth 20% of the CCA-F exam. The trap answers in this domain are the most seductive on the entire test because they sound right.
You will see three patterns over and over:
The Domain 3 traps:
—Trap 1: Prompt-only solutions when code enforcement is needed
—Trap 2: Wrong model for the task (using Opus when Haiku is correct)
—Trap 3: Missing structured output validation
Each one feels like the right answer. That's what makes them traps.
