Which primary advantage does deploying an AWS RDS instance in Multi-AZ mode provide?
easy📝 Conceptual Q1 of 15
Step-by-Step Solution
Solution:
Step 1: Understand Multi-AZ purpose
Multi-AZ deployment is designed to increase availability and durability by automatically failing over to a standby instance in another AZ if the primary fails.Step 2: Evaluate options
Automatic failover to a standby instance in case of primary AZ failure correctly describes automatic failover. Improved read performance by distributing read traffic describes read replicas, not Multi-AZ. Reduced storage costs by sharing data across AZs is incorrect as Multi-AZ increases cost. Faster backups by using multiple AZs simultaneously is unrelated to Multi-AZ benefits.Final Answer:
Automatic failover to a standby instance in case of primary AZ failure -> Option CQuick Check:
Failover is the key Multi-AZ benefit [OK]
Quick Trick: Multi-AZ ensures failover, not read scaling [OK]
Common Mistakes:
MISTAKES- Confusing Multi-AZ with read replicas
- Assuming Multi-AZ reduces costs
- Thinking Multi-AZ speeds up backups
