BIt stores backups in different AWS services

CIt increases fault tolerance by isolating failures to one AZ

DIt automatically scales the application to more regions

Step-by-Step Solution

Solution:

Step 1: Understand multi-AZ deployment
Deploying in multiple AZs protects the app from failure in one AZ by isolating faults.
Step 2: Analyze options
It reduces latency by serving users from multiple continents is about continents, not AZs. It automatically scales the application to more regions talks about regions, which is different. It stores backups in different AWS services is unrelated to AZ deployment.
Final Answer:
It increases fault tolerance by isolating failures to one AZ -> Option C
Quick Check:
Multi-AZ = better fault tolerance [OK]

Quick Trick: Multiple AZs protect from single data center failure [OK]
