Microservices - Authentication and Authorization

Given this simplified RBAC check in a microservice:

def can_access(user_role, action):
    permissions = {
        "user": ["read"],
        "admin": ["read", "write", "delete"]
    }
    return action in permissions.get(user_role, [])

print(can_access("user", "delete"))

What is the output?

ANone

BTrue

CKeyError

DFalse

Step-by-Step Solution

Solution:

Step 1: Understand permissions dictionary
The "user" role has only ["read"] permission, no "delete".
Step 2: Check if "delete" is in user permissions
Since "delete" is not in ["read"], the function returns False.
Final Answer:
False -> Option D
Quick Check:
"delete" in user permissions = False [OK]

Quick Trick: Check if action is in role's permission list [OK]

Common Mistakes:

MISTAKES

Assuming all actions allowed for user
Expecting KeyError for missing keys
