- A
Deploy DMS on-premises as a virtual appliance.
Why wrong: DMS is a managed cloud service; not deployed on-premises.
- B
Set up VPC peering between the on-premises network and the DMS VPC.
VPC peering allows DMS to connect to the source database if the network is peered.
- C
Use a public IP for the source database with SSL.
Why wrong: Possible but not recommended; DMS can connect over public IP if authorized.
- D
Configure Cloud SQL Auth Proxy on the source server.
Why wrong: Auth Proxy is for client-to-Cloud SQL connections, not for DMS source connectivity.

PCD Migrate Data Solutions Practice Question
This PCD practice question tests your understanding of migrate data solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An engineer is using Database Migration Service for a continuous migration from on-premises MySQL to Cloud SQL. The source database is not directly reachable from DMS due to network restrictions. Which connectivity option should the engineer configure?

Correct answer & explanation
✓
Set up VPC peering between the on-premises network and the DMS VPC.
DMS requires network connectivity to the source. If direct VPC peering is not possible, the Cloud SQL Auth Proxy can be used (though typically for Cloud SQL to client, not for DMS source). The correct method is to use a public IP with authorized networks or a VPN. However, among the options, Cloud SQL Auth Proxy is not for source connectivity; VPC peering is correct if networks are peered. The best answer here is to use a VPN or VPC peering. Since DMS supports VPC peering and also reverse SSH tunnel (but not listed), the most plausible correct answer is VPC peering.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
