    Diffrence between http and https
    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.

Advice: Know your application's code properly. And just go through the questions from this spreadsheet. I also did that. A proctor generally asks similar type of questions everytime that's how I got all the common questions that I prepared from this sheet. Biggest Tip: If you haven't used a feature in your project, like in my case it was APIs, just say it politely and he most likely will not ask questions from there😅 Anyways at the end, he 's good proctor. Told me that my project was nice ☺️ and I should explore the APIs as well and more on OOP.

    PUT vs PATCH
    Times asked 2
    Official solution

    SimplePOST naya janam (har baar naya id). PUT poori photo replace. PATCH sticker chipkao.

    POST create, not idempotent. PUT full update, idempotent. PATCH partial.

    POST ki jagah PUT se REST semantics toot. GET typically no body.

    CRUD map: POST create, GET read, PUT/PATCH update, DELETE delete.

    Pehle 1-line definition, phir related MAD2 layer (Vue SFC / Flask route / models.py / tasks.py / Redis).

    4-line formula: input kahan se aaya, auth/validation kaunsa, DB ya cache ya Celery, kya return.

    Related mix mat karo — cache ≠ Celery, authentication ≠ authorization, v-if ≠ v-show, Beat ≠ Worker. Follow-up ke liye ek difference ready rakho.

    Example

    POST /api/venues
PUT  /api/venues/1   {all fields}
PATCH /api/venues/1 {only name}

    Project example: POST /api/venues create. PUT /venues/1 saari fields. PATCH sirf name.
