Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a VPC peering connection between the source and DMS.
Why it's wrong here
VPC peering is used for private IP connectivity, not public IP.
- ✗
Install the Cloud SQL Auth Proxy on the source database.
Why it's wrong here
Cloud SQL Auth Proxy is used for connecting to Cloud SQL, not for DMS connectivity from source.
- ✓
Allowlist the DMS public IP addresses in the source database firewall.
Why this is correct
DMS connects from its own IP range; allowlisting those IPs enables the connection.
- ✗

Why it's wrong here
VPN is used for private connectivity but not required if the source has a public IP.
