Microservices - Resilience Patterns

Identify the issue in this retry logic:

max_retries = 4
base_delay = 100
for retry in range(max_retries):
  delay = base_delay * (2 ** retry)
  if retry == max_retries:
    print("Retries exhausted")
  else:
    print(f"Waiting {delay}ms before retry")

AThe condition retry == max_retries is never true inside the loop

BThe delay calculation should use addition instead of multiplication

CThe loop should start from 1 instead of 0

DThe base_delay should be doubled each iteration manually

Step-by-Step Solution

Solution:

Step 1: Analyze loop range
range(max_retries) iterates from 0 to max_retries - 1, so retry == max_retries never occurs.
Step 2: Impact
The "Retries exhausted" message will never print inside the loop.
Final Answer:
The condition retry == max_retries is never true inside the loop -> Option A
Quick Check:
Loop index never equals max_retries [OK]

Quick Trick: Loop index max is max_retries - 1, not max_retries [OK]

Common Mistakes:

MISTAKES

Expecting loop variable to reach max_retries
Incorrect delay calculation assumptions
Misunderstanding loop ranges
