Level 5 exam — harder

Exam — hardened questions

5.1 · Recall

1. What is lever #1 to speed up a site?

Images are often the first cause of slowness: compressing and sizing them (WebP) is lever #1.
5.1 · Application

2. What do the Core Web Vitals measure?

The Core Web Vitals (Google) measure perceived speed and stability; you aim for green and measure before/after.
5.1 · Arbitration

3. The site is slow on mobile with big photos. What's the priority?

You compress the images (lever #1), enable a cache, and re-measure. Speed retains visitors and helps SEO.
5.2 · Recall

4. What is over-nesting?

Over-nesting is stacking useless containers: it complicates responsive and maintenance.
5.2 · Arbitration

5. A section has 5 levels of nested containers. What to do?

You simplify: the simplest structure that gives the wanted result is the most robust and the easiest to make responsive.
5.2 · Application

6. What does a clean structure make easier?

A simple, logical structure adapts easily to screens (Flexbox) and is more easily maintained.
5.3 · Recall

7. How many H1s per page?

A single H1 per page, then H2/H3 in a hierarchy — good for SEO and accessibility.
5.3 · Application

8. What is the alternative text (alt) for?

The alt describes the image for engines (SEO) and screen readers (accessibility): a perfect common ground.
5.3 · Arbitration

9. Are SEO and accessibility separate, optional projects?

They largely meet (heading structure, alt, contrast) and are essential: polishing one often serves the other.
5.4 · Recall

10. What is an Elementor kit for?

A kit exports a configuration (styles, templates, settings) reusable from one project to another.
5.4 · Application

11. When should you back up?

You back up regularly and above all before any intervention (update, change), to be able to roll back.
5.4 · Arbitration

12. What does a truly pro delivery include?

Deliver clean = backup + tests (responsive, speed, links, forms) + documentation + maintenance planned. The work includes what comes next.
5.4 · Application

13. Why a test environment (staging)?

A test environment lets you try major changes (updates) risk-free before applying them in production.
5.1 · Application

14. What complements image compression for speed?

After images: a cache (minification), good hosting, a light theme and Elementor's optimization options (light containers).
