Programming MCQ

Q: Application database users should have:

Correct answer: Least privilege — only the CRUD rights they need. Compromised apps then cannot drop tables or create users.

Q: The tool pair for finding slow queries is:

Correct answer: The slow query log plus EXPLAIN. Measure, explain, index — the performance discipline.

Q: The professional first step of a website project is:

Correct answer: Writing a one-page plan: purpose, users, tasks, sitemap. Requirements and structure decisions steer everything; code without them is rework waiting to happen.

Q: Real content should replace placeholder text:

Correct answer: As early as possible — placeholders hide layout problems. Lorem ipsum conceals overflow, length and hierarchy issues until they are expensive.

Q: Decorative images should have:

Correct answer: alt="" so screen readers skip them. Empty alt marks decoration; missing alt makes screen readers read the filename.
