A test for a distributed system intermittently fails due to race conditions between services. Which change would best help fix this issue?

medium📝 Conceptual Q14 of 15

Microservices - Testing Microservices

AAdd retries with exponential backoff to handle timing issues

BRemove all network timeouts to avoid errors

CRun all services on the same machine to avoid network delays

DIgnore the failures since they happen rarely

Step-by-Step Solution

Solution:

Step 1: Identify cause of intermittent failures
Race conditions cause timing-related failures; retries with backoff help by spacing attempts to reduce conflicts.
Step 2: Evaluate options for fixing race conditions
Add retries with exponential backoff to handle timing issues adds retries with exponential backoff, a common pattern to handle timing issues. Options A, C, and D are ineffective or harmful.
Final Answer:
Add retries with exponential backoff to handle timing issues -> Option A
Quick Check:
Retries fix race timing = B [OK]

Quick Trick: Use retries with backoff to handle timing-related test failures [OK]
