Why wrong: REST linked service is for REST APIs.
Question 403 of 851
Setting Up FTP Linked Service in Azure Data Factory
This DP-203 practice question tests your understanding of develop data processing. 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.
You are designing a data pipeline that uses Azure Data Factory to load data from an FTP server to Azure Data Lake Storage. The FTP server requires authentication with username and password. Which type of linked service should you create?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
FTP
Option A is correct because Azure Data Factory provides a native FTP connector that supports username/password authentication for connecting to FTP servers. This linked service type is specifically designed to handle the FTP protocol (RFC 959) and allows you to copy data directly from an FTP server to Azure Data Lake Storage without requiring any additional gateways or custom activities.
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
The trap here is that candidates often confuse the FTP connector with the HTTP or REST connector because they think all file transfers can be handled by generic web protocols, but FTP has its own distinct authentication and command set that requires a dedicated connector.
Detailed technical explanation
How to think about this question
The FTP linked service in ADF uses the FTP protocol's USER and PASS commands for authentication, and it supports both active and passive modes. Under the hood, ADF's FTP connector handles the control connection for commands and data connection for file transfers, which is distinct from HTTP-based connectors. In real-world scenarios, if the FTP server requires explicit FTPS (FTP over SSL/TLS), you would need to use the FTPS connector instead, as the standard FTP connector does not encrypt the control channel.
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.
TExam Day Tips
- 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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
