5.and asked me about MVC and that structure in my folder if i have implemented it

db.session.add(user)
db.session.commit()
users = User.query.filter_by(role='admin').all()
```

15.He gave a situation and asked what i could like "If a db error has occured how will you manage the situation" ans:exception handling can be implemented

Times asked 1
Official solution

Simpletry/except. Catch Exception not BaseException (SystemExit). IntegrityError 404 abort.
Exception handling. Types ValueError TypeError KeyError IntegrityError HTTPException.
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
```
try:
    db.session.commit()
except IntegrityError:
    db.session.rollback()
    return jsonify(msg='duplicate'), 400
```
Project example: commit except rollback 400.

Difference between authentication and authorisation

Times asked 4
Official solution

SimpleAuthentication: tu kaun hai? (login). Authorization: tujhe permission hai? (role check).
Example
```
# auth
if check_password_hash(user.password, pwd):
    session['user_id'] = user.id

# authz
if user.role != 'admin':
    abort(403)
```
2
Different HTTP methods

Times asked 1
Official solution

SimpleHTTP verbs REST ke tools. Methods HTTP ke hain, REST unhe convention se use karta hai.
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
```
GET /api/venues
POST /api/venues
PUT /api/venues/1
DELETE /api/venues/1
```
Project example: resources.py methods list. Postman 4-5 calls.
Viva tipGET typically no body (cacheable). POST/PUT/PATCH haan payload. PUT idempotent, POST nahi.

Advice: Very friendly proctor. He waits patiently for you to think and then code or answer. Also better to demonstrate downloading the project file from the vivabooking website submission page itself. You mostly wont need to perform checksum if thats the case. Just be confident and answer with conviction.
