GCP - Cloud SQL and Databases

AIt uses IAM authentication and encrypted tunnels, avoiding exposure of IP and passwords

BIt automatically backs up data during connection

CIt disables all firewall rules on the Cloud SQL instance

DIt caches queries locally to reduce network traffic

Step-by-Step Solution

Solution:

Step 1: Understand proxy security features
Cloud SQL Proxy uses IAM-based authentication and encrypted tunnels, so no need to expose IP or passwords.
Step 2: Evaluate incorrect options
Backup, firewall disabling, and caching are unrelated to proxy's security role.
Final Answer:
It uses IAM authentication and encrypted tunnels, avoiding exposure of IP and passwords -> Option A
Quick Check:
Proxy security = IAM + encryption, no IP exposure [OK]

Quick Trick: Proxy uses IAM and encryption, hides IP [OK]
