    Times asked 1
    Official solution

    SimpleExaminer wohi ZIP chahta hai jo tumne submit kiya, local extra magic nahi.

    Examiner 2 cheezein: simple desi line + tumhare project ki exact file.

    Pehle ID, GitHub, portal ZIP. Phir run: Redis + Flask + worker + beat + Vue. Feature demo: login, RBAC, cache hit/miss, Celery mail, search.

    Line pe ungli: input kahan, kaunsa check, query/cache/task, JSON/UI. Copilot band. Jo nahi kiya honestly bolo + kaise add karte.

    Suggested flow1) ZIP
    2) Extract
    3) Redis + venv + pip
    4) npm/vite
    5) flask + celery worker + beat

    10> tell me the difference between Put and Post.
    Times asked 1
    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.

    Where have you used JWT? and where it stores it's data?
    Times asked 2
    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.

  3. 3
    for what v-if and v-for used for?
    Times asked 2
    Official solution

    Simplev-if ghar se nikaal deta hai (DOM se). v-show sirf light band karta hai (display:none).

    v-if false → element exist hi nahi — costly create/destroy, lekin secret HTML DOM mein nahi.
    v-show → hamesha DOM, CSS hide, toggle tez.

    Rare / permission UI: v-if (admin panel). Dropdown bar-bar: v-show.

    : shorthand v-bind ka, v-if ka nahi.

    Example

    <div v-if="isAdmin">Admin panel</div>
<div v-show="open">Dropdown</div>

    Project example: Admin links v-if="role==='admin'". FAQ accordion v-show="open".

    Viva tipSecurity ke liye sirf v-if kaafi nahi — API 403 bhi chahiye.

    Jwt and RBAC and show jwt stored area
    Times asked 2

    SimpleRBAC = Role Based Access Control. Roles (admin/user) se permissions milti hain, har user pe alag list nahi.

    if current_user.role != 'admin':
    flash('Not allowed')
    return redirect(url_for('user.home'))

    Why asynchronous and awaits are used
    Times asked 2
    Official solution

    SimpleSync line pe ruk jao (2+2). Async I/O pe wait karte hue baaki kaam chalte (fetch, Celery).

    JS async ≠ Celery async jobs. Context se bolo.

    Why async jobs: slow/scheduled/bulk off request thread.

    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.

    Project example: Login sync hash check fast. Email Celery async. Vue fetch async.

    Vue lifecycle hooks
    Times asked 4
    Official solution

    SimpleLifecycle = component ki zindagi ke stages. API call tab jab DOM ready ho — mounted.

    created: instance bani, this data, DOM nahi. mounted/onMounted: page pe aa gaya — fetch, Chart.js, setInterval.
    updated: data change ke baad. unmounted: cleanup (clearInterval) warna memory leak.

    Dashboards onMounted isliye: canvas/API tab valid. created mein $el nahi.

    Composition: onMounted(() => {}) setup ke andar.

    Example

    export default {
  async mounted() {
    const r = await fetch('/api/venues')
    this.venues = await r.json()
  }
}

    Project example: Venues.vue mounted fetch list. Clock component unmounted pe interval clear.

    Viva tipcreated: data setup, DOM nahi. mounted/onMounted: $el mil gaya — fetch yahi. Dashboards isliye onMounted use karti hain.

    Show JWT, if used.
    Times asked 2
    Official solution

    SimpleJWT teen tukde ki signed chitthi: header.payload.signature. Padhi ja sakti hai, badli nahi ja sakti.

    Encoded (Base64) + signed, encrypted nahi (JWE alag). Payload mein password mat daalo — koi jwt.io pe dekh lega.

    Login pe server secret se HMAC (HS256). Har API Authorization: Bearer <token>.
    Expiry exp. Change payload → signature fail → 401.

    Session MAD1 server yaad rakhta. JWT MAD2 client rakhta, server stateless-ish.

    Example

    eyJhbGciOiJIUzI1NiJ9.{"sub":1,"role":"admin"}.signature
# Authorization: Bearer <token>

    Project example: POST /login → token LS. fetch interceptor header. @jwt_required APIs.

    Show a Celery task executing (e.g. mail sending)
    Times asked 2
    Official solution

    SimpleCelery = background naukri. HTTP request ko 10 second email bhejne ke liye mat rokna.

    Distributed task queue: aap function ko abhi nahi, worker process mein later/retry/schedule pe chalaate ho.

    MAD2 typical jobs: daily reminder mail, monthly HTML report, user-triggered CSV export.

    Web request 200ms hona chahiye. 10,000 emails request thread mein = timeout. Worker alag CPU pe kaam kare.

    Redis broker chahiye. Beat alag process schedule ke liye.

    Example

    @celery.task
def daily_reminder():
    for u in User.query.filter_by(active=True):
        send_mail(u.email, 'Book something today!')

    Project example: User Export click → 202 Accepted. Worker CSV + email. Daily 6pm Beat reminder.

    Viva tipWorker + Redis bina Beat ke user-triggered chalega. Scheduled jobs ke liye Beat bhi chahiye.

    2) Input kahan se aata hai (form, URL <id>, session, JSON)?
    3) DB pe kya query/write?
    4) Output kya (render_template / redirect / jsonify)?

    Example

    @app.route('/book/<int:id>', methods=['POST']) — logged-in user session se, trek id URL se, Booking add, slots--, redirect history.

    SimpleTask function, beat dict, delay() call, worker+beat terminals, MailHog/CSV.

    App context DB. Args serializable. How many jobs: reminder, monthly, export — gino honestly.

    Celery Python ka distributed task queue — HTTP request ko 10s email/CSV ke liye mat rokna.

    Flow: Flask .delay() → Redis broker → Worker execute. Beat alag process hai (clock): crontab padhke due time pe queue mein daalta hai. Beat khud mail nahi bhejta; Worker haath hai.

    MAD2 typical: daily reminder (Beat), monthly report (Beat), user Export CSV (button, Beat nahi). JS async/await browser event loop hai, Celery server-side process — mix mat karo.

    Demo: tin terminals — redis-server, celery worker, celery beat — plus Flask. MailHog :8025 inbox. Result backend se task SUCCESS poll optional.

    Project example: tasks.py + config schedule + POST export.

Advice: Examiner is chill. Remain relaxed, and answer confidently upto the extent you know, no need to panic as he gives ample time to think and answer. Mostly the above questions will get repeated in your case too. Happy Learning.

    *What is axios.
    Times asked 2
    Official solution

    SimpleAxios HTTP library: JSON auto, interceptors, timeout. fetch built-in alternative.

    Na use kiya: 'fetch native, extra lib nahi' valid.
    Use kiya: interceptor mein token. Why didn't: deps kam.

    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

    axios.get('/api/venues', { headers: { Authorization: 'Bearer ' + token } })

    Project example: axios.defaults.headers.common.Authorization. baseURL :5000.

    Times asked 2
    Official solution

    SimpleJWT teen tukde ki signed chitthi: header.payload.signature. Padhi ja sakti hai, badli nahi ja sakti.

    Encoded (Base64) + signed, encrypted nahi (JWE alag). Payload mein password mat daalo — koi jwt.io pe dekh lega.

    Login pe server secret se HMAC (HS256). Har API Authorization: Bearer <token>.
    Expiry exp. Change payload → signature fail → 401.

    Session MAD1 server yaad rakhta. JWT MAD2 client rakhta, server stateless-ish.

    Example

    eyJhbGciOiJIUzI1NiJ9.{"sub":1,"role":"admin"}.signature
# Authorization: Bearer <token>

    Project example: POST /login → token LS. fetch interceptor header. @jwt_required APIs.

    GET read cacheable. POST create payload. PUT replace. PATCH patch. DELETE remove.

    GET exists bina REST ke bhi — browser address bar.

    HTTP verbs + status REST ki zabaan. GET read, POST create, PUT replace, PATCH partial, DELETE remove. GET typically no body.

    Status: 200 OK, 201 created, 202 accepted (Celery task), 400 bad input, 401 no/bad token, 403 role nahi, 404 missing, 409 conflict (double book), 500 server.

    AJAX/fetch page reload nahi. SPA poori isi pe. Postman se bina Vue ke API prove karo — examiner pasand.

    Example

    Times asked 2
    Official solution

    SimpleCache = pehli baar hisaab karke copy rakh lo, doosri baar copy dikha do.

    Baar-baar same expensive kaam (DB query, counting bookings) mat karo. Result Redis jaise store mein timeout ke saath rakh do.

    Cache hit: key mil gayi, DB skip. Cache miss: DB se lao, SET karo, return karo.

    Tradeoff: speed vs stale data. Admin naya venue add kare aur cache 50s ka ho to user purani list dekh sakta hai — isliye write pe invalidation zaroori hai.

    Browser cache, Flask-Caching, Redis alag layers hain. MAD2 examiner Redis + @cache.cached code dekhta hai.

    Example

    @cache.cached(timeout=50, query_string=True)
@app.route('/api/shows')
def shows():
    return jsonify([s.serialize() for s in Show.query.all()])

    CDN: no build, chhote apps, exam PC pe Node nahi to bhi chal. Weak: no .vue compile, 3rd-party cache, scale/team.

    CLI/Vite: Single File Components, env, code-split, production dist/. Scalable.

    What is ORM?
    Times asked 49
    Official solution

    SimpleORM = Object Relational Mapping. Database tables ko Python classes/objects se map karta hai, raw SQL kam likhni padti hai.

    Bina ORM: cursor.execute('SELECT * FROM user WHERE id=?', [5])
    ORM se: User.query.get(5) ya db.session.get(User, 5)

    Example model

    class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(120), unique=True)

    FaydePython mein soch sakte ho, SQL injection se protection (parameterized), relationships easy, DB switch thoda aasan.

    Nuksaancomplex queries slow/abstract, seekhne ki layer extra, kabhi raw SQL phir bhi chahiye.

    Portal pe submitted ZIP ka checksum diya hota hai. Local file ka hash nikaalo, match hona chahiye.
    Linux: sha256sum project.zip
    Mismatch = galat file / corrupt download. Examiner integrity check karta hai ki tumhari submitted copy hi run ho rahi hai.

    SimpleCRUD = Create, Read, Update, Delete — kisi bhi resource ke 4 basic operations.

    Create: POST, db.session.add(new_user); commit() — register, add trek.
    Read: GET, User.query.all() — dashboard list.
    Update: POST/PUT, user.name = 'Ram'; commit() — edit profile.

    DeletePOST/DELETE, db.session.delete(obj); commit().

    REST mapping: POST create, GET read, PUT/PATCH update, DELETE delete.
    Admin panel mein yeh 4 dikhana viva demo ka common task hai.

    SimpleSearch box GET form, backend query filter, results template mein.

    q = request.args.get('q', '').strip()
results = Doctor.query.filter(Doctor.name.ilike(f'%{q}%')).all() if q else []
return render_template('search.html', results=results, q=q)

    Jinja: {{ results|length }} matches. Empty: 'No results'.
    JS-only filter: saara data pehle load, client filter — chhote lists. Bada data: server search.
    Search generally GET (shareable URL). Count: len(results) ya db.func.count.

    SimpleBlacklist flag user/company ko block karta hai — login ya features band.

    user.is_blacklisted = True; db.session.commit()
    Login: if user.is_blacklisted: flash('Blocked'); return
    Student dashboard: blacklisted company ke drives hide — query filter join Company.is_blacklisted==False.
    Demo: admin blacklist → us user se login fail.

    Open routes.py and explain the registration route using your project code.
    Times asked 1
    Official solution

    SimpleRoutes/controllers URLs handle karte hain. app.py app banata hai, models.py data, templates/ views, static/ CSS-JS.

    Typical structure:
    app.py / __init__.py → Flask app, db.init, register blueprints
    models.py → tables
    routes.py / views → @app.route functions
    templates/ → Jinja HTML
    static/ → css, images
    instance/*.db → SQLite

    Ek route explain karne ka template:
    1) URL + methods 2) Auth/role check 3) Form/query se data 4) Business rule (duplicate, slots) 5) db.session 6) render ya redirect

    Example GET+POST same route: GET form, POST save.
    Data HTML se: form name= → request.form. Data HTML ko: render_template(..., items=query).
    Nayi .py file: import karke use karo, warna Flask ko pata nahi. Folder rename: imports/paths/templates check.

    What is ORM?
    Times asked 49
    Official solution

    SimpleORM = Object Relational Mapping. Database tables ko Python classes/objects se map karta hai, raw SQL kam likhni padti hai.

    Bina ORM: cursor.execute('SELECT * FROM user WHERE id=?', [5])
    ORM se: User.query.get(5) ya db.session.get(User, 5)

    Example model

    class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(120), unique=True)

    FaydePython mein soch sakte ho, SQL injection se protection (parameterized), relationships easy, DB switch thoda aasan.

    Nuksaancomplex queries slow/abstract, seekhne ki layer extra, kabhi raw SQL phir bhi chahiye.

    MAD1: SQLAlchemy (Flask-SQLAlchemy). Tables db.create_all() ya migrations se banti hain.

    Explain MVC architecture.
    Times asked 9
    Official solution

    SimpleMVC = Model-View-Controller. Code ko 3 hisson mein baant ta hai taaki mix na ho.

    Model: data + DB. models.py — User, Trek, Booking classes.
    View: jo user dekhta hai. templates/*.html + Jinja.
    Controller: beech ka logic. routes / app.py — request lo, model se data, view ko do.

    Example flow (register):
    Browser form POST → Controller register() → User model save → redirect → View dashboard.html

    Draw: Browser → Controller → Model → DB, phir Controller → View → Browser.
    ORM na ho to bhi MVC ho sakta hai — Model raw SQL functions ho sakte hain. Structure matter karta hai, library nahi.
    MVP/MVVM doosri architectures hain; MAD1 mein MVC expected hai.

    Difference between Authentication and Authorization.
    Times asked 20
    Official solution

    SimpleAuthentication poochta hai "tu kaun hai?", Authorization poochta hai "tujhe yeh kaam karne ki permission hai?"

    Authentication: login. Username + password check karke prove karte ho ki tum genuine user ho. Success pe session/token milta hai.
    Authorization: uske baad role check. Admin hi parking lot delete kar sakta hai, normal user nahi.

    Example (Flask):
    # Authentication

    if user and check_password_hash(user.password, form_password):
    session['user_id'] = user.id

# Authorization
if session.get('role') != 'admin':
    abort(403)  # logged in ho, lekin allowed nahi

    Project example: student login = authentication. Student admin dashboard nahi khol sakta = authorization.
    Validation alag cheez hai (form sahi bhara hai ya nahi, jaise age 18+).

    Write a Flask registration route in Notepad/VS Code.
    Times asked 1
    Official solution

    Register + Login skeleton (Notepad):

    @app.route('/register', methods=['GET','POST'])
def register():
    if request.method == 'POST':
        if User.query.filter_by(email=request.form['email']).first():
            flash('Exists'); return redirect(url_for('register'))
        u = User(email=request.form['email'],
                 password=generate_password_hash(request.form['password']))
        db.session.add(u); db.session.commit()
        return redirect(url_for('login'))
    return render_template('register.html')

    Login upar wale login-flow answer jaisa — check hash, session, redirect.
