Bring the ideas back
Outcome: Recall and apply the central ideas from the lessons due today without rereading them first.
Before you begin
Try each prompt from memory. Then reveal the model answer and compare the idea, not the exact wording. If the idea is unclear, reopen the original lesson after the attempt.
Today’s review covers ITF-001. The +1, +3, and +7 day intervals are overdue; the questions therefore mix simple recall, a new application, and a comparison.

How DNS helps your browser find a website
DNS lets people use readable domain names while computers obtain the network records they need, including IP addresses, so a device can contact the right server.
DNS only helps find where to connect (the address linked to the name). HTTPS protects the connection, and the browser requests and displays the webpage. DNS does not download or show the page.
The resolver may already hold a valid, unexpired answer in its cache, so it can reuse that information without repeating the full hierarchical lookup.
Review finished?
Record any idea that still feels unclear when reporting the result. Do not mark the review complete in the ledger until you have finished the attempt.
