18

- Then he asked me the difference between http and HTTPS. Which I did.

Times asked 1

Official solution

SimpleHTTP postcard (koi padh le). HTTPS envelope (TLS lock).
Same headers, encrypted channel. MITM se password/token bachao. Local viva HTTP OK.
HTTP/1.1 version keep-alive. TCP neeche, TLS security layer, SMTP mail alag.
Browser + API ke beech extra darwaze: CORS origin allow, HTTPS encrypt transit, CSRF cookie-auto-send attack, XSS HTML inject, SQL injection raw query.
MAD2 SPA: Vue :8080 Flask :5000 → Flask-CORS. JWT localStorage XSS se chori ho sakta — v-html user input pe avoid. Password Network tab localhost pe dikhega; prod HTTPS, response mein password echo nahi.
401 unauthenticated, 403 unauthorized, 400 validation. Hash one-way — SHA decrypt nahi hota. Secret key .env, GitHub pe nahi.
Project example: Dev localhost http. Production https:// + cert.
Viva tipProtocols: HTTP/HTTPS app, TCP transport, TLS security, SMTP mail. HTTP/1.1 version — persistent connections.
19

- He also asked what is meant by MVC. Which again I did.

Times asked 1

Official solution

SimpleMVC: Model=data (SQLAlchemy), View=Jinja HTML, Controller=Flask routes/business logic.
Flask loosely MVC follow karta hai — routes controllers, templates views, models.py models.

When the company gets blacklisted, make sure that any drive from that particular company(even if the student got selected) should not be shown in the student dashboard.

Times asked 1

Official solution
