1.Diff btw id and class in html

Times asked 1
Official solution

Simple:class object/array/string dynamic CSS.
Purpose dynamic class. Error red.
Directives Vue ke special attributes hain — HTML ko superpower: v-if/v-show, v-for, v-bind (:), v-on (@), v-model.
v-if DOM se hataata/jodta. v-show sirf CSS display. Rare/permission: v-if. Bar-bar toggle: v-show. v-model two-way form. v-bind one-way JS→attribute.
:key v-for pe zaroori warna Vue galat reuse. v-html XSS. Secret UI ke liye sirf v-if kaafi nahi — API 403 bhi.
MAD1 Jinja server HTML. MAD2 yeh directives browser mein reactive.
Example
```
<div :class="{ 'text-danger': error, 'fw-bold': important }">Msg</div>
```
Project example: :class="{ 'text-danger': error }"

where is the metadata stored?

Times asked 1
Official solution

Simpledata() local diary. Store school notice board.
Search query local. Logged-in user store. Persist: store + localStorage together.
state vs data: similar concept, scope alag.
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
```
// local
data() { return { q: '' } }
// global
this.$store.state.user
```
Project example: Login.vue local form fields. this.$store.state.user Navbar.

difference between client server and multi-server architecture? (the viva lasted for about 40 minutes)

Times asked 1

Official solution

SimpleMAD1 typical: Browser → Flask routes → validate/auth → SQLAlchemy → SQLite → Jinja response.
Suggested flowRequest → Route → Auth check → DB → render_template / redirect

Advice: he is a chill proctor, he asks all the questions from the sheet, so revise that well and go. from observation, he focuses on the backend part in the coding/code change questions, rather than asking to write the frontend code. in my case, not much code changes were asked. i also noticed he was asking me the exact topics ive already said during the demo, so he REALLY has that set of questions he always tests from. so DONT FORGET to check the sheet.
