NestJS - Guards

Consider this scenario: You have a global guard and a controller guard. The global guard denies access, but the controller guard allows it. What will be the final result when accessing a route in that controller?

AAccess will be allowed because the controller guard overrides the global guard

BBoth guards will run but the last one decides access

CAn error will occur due to conflicting guard results

DAccess will be denied because the global guard runs first and blocks the request

Step-by-Step Solution

Solution:

Step 1: Understand guard execution order
Global guards run before controller guards in NestJS.
Step 2: Analyze guard effect on request
If the global guard denies access, the request is stopped immediately, so controller guard is not reached.
Final Answer:
Access will be denied because the global guard runs first and blocks the request -> Option D
Quick Check:
Global guard deny stops request early = Access will be denied because the global guard runs first and blocks the request [OK]

Quick Trick: Global guard deny stops request before controller guards run [OK]

Common Mistakes:

Assuming controller guard can override global guard
Expecting errors from guard conflicts
Thinking last guard decides access
