01The cost of failing

Failing is the expensive way to practice

Score reportNot passed
Marked wrong

01 · Retake fees

AZ-900 retake: $99. Security+: $404. Every attempt is full price.

03 · Repeat odds

The retake pass rate is LOWER than the first-try rate — people who don’t change how they practice fail again.

The fix isn't more videos. It's seeing exam-format questions until nothing on test day is new.

02Try a question

Question 14 · Cloud concepts00:47

Which cloud deployment model gives an organization sole control over its infrastructure?

APublic cloud
BPrivate cloudCorrect answer
CHybrid cloud
DCommunity cloud

B is correct — a private cloud is operated for a single organization. Public and community clouds share infrastructure across tenants, so neither grants sole control.

Every question explains why each wrong answer is wrong.

Your weak domains, tallied.

Timed mode mirrors the real clock.
