How do practice questions check understanding?

Choose the direction of knowledge you are learning, explain the principles, premises and boundaries independently, and then analyze and find out the omissions. When you need to make up lessons, use "Learn Corresponding Knowledge" to return to the explanation; when you need to verify the implementation, complete the hands-on tasks on the page.

The questions are designed based on public official information and engineering boundaries. The scale, faults and goals in the cases are teaching assumptions. The reference materials support the technical mechanism, and the Q&A, migration scenarios and self-evaluation standards are designed by this site.

When preparing for the interview, explain the principles, boundaries, and trade-offs in your own words, and then check against the basic compliance, intermediate and advanced signals, and senior signals. Reading records and single answers do not directly represent mastery.
