Which type of cookie is not erased when you leave the site and helps the site remember you across visits?

• A. Session cookies
• B. Persistent first-party cookies
• C. Third-party cookies
• D. Local storage cookies

Answer: (B)

Persistent first-party cookies are designed to survive beyond a single browsing session. They’re set by the site you’re visiting (the first party) and have an expiration date, so they stay on your device after you close and later return to the site. This persistence lets the site recognize you on subsequent visits, keep you logged in, and remember your preferences. By contrast, session cookies vanish when you close the browser, so they don’t remember you across visits. Third-party cookies come from external sites embedded on the page (like advertisers) and aren’t aimed at helping the site you’re visiting remember you. Local storage is a separate storage mechanism in the browser and not a cookie, even though it can also persist data. So the type that fits the description—not erased when you leave the site and helping the site remember you across visits—is persistent first-party cookies.
