What are common uses of cookies in web applications? (Choose two)

Question

Options

• ATo store user preferences
• BTo enforce strict password policies
• CTo maintain user sessions
• DTo encrypt all HTTP traffic

• A
  72% (33)
• B
  11% (5)
• D
  17% (8)

Explanation

Cookies are small pieces of data stored by a browser that allow web servers to persist information across requests. Storing user preferences (A) is a classic cookie use - things like language, theme, or font size are saved so they persist between visits. Maintaining user sessions (C) is arguably the most critical cookie use: a session token stored in a cookie lets the server recognize an authenticated user across multiple requests without requiring re-login on every page.

B is wrong because password policies are enforced server-side through validation logic, not cookies. D is wrong because HTTPS/TLS handles traffic encryption at the transport layer - cookies have no role in encrypting HTTP traffic.

Memory tip: Think of cookies as a browser's "sticky note" - they remember who you are (session) and how you like things (preferences). Encryption and security policies live on the server, not in a sticky note.
