Quick Answer
The correct choice is to configure the EHR data source to use SFTP for file transfer. SFTP, or SSH File Transfer Protocol, encrypts the CSV file during transit over the network, directly addressing the need to encrypt data in transit for Customer Insights with SFTP. Since the on-premises EHR system sends a nightly batch file, SFTP ensures that protected health information is encrypted while moving to the cloud, complementing Dynamics 365’s default encryption at rest and satisfying HIPAA requirements for ePHI transmission. On the MB-910 exam, this scenario tests your understanding of data protection layers: encryption at rest is automatic, but you must choose the right protocol for data in transit. A common trap is confusing FTPS with SFTP—remember that SFTP uses SSH for encryption, not SSL/TLS. For a quick memory tip: think “S for Secure Shell” when you see SFTP, and recall that batch files from on-premises systems need encrypted file transfer, not real-time API encryption.
This MB-910 practice question tests your understanding of describe dynamics 365 customer insights. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 the Dynamics 365 administrator for a healthcare provider that uses Customer Insights to manage patient profiles. The organization must comply with HIPAA regulations. Patient data is sourced from an electronic health record (EHR) system and from a patient portal. The EHR system is on-premises and sends data via a nightly batch file in CSV format. The patient portal sends data in real-time via API. You need to ensure that all patient data in Customer Insights is encrypted at rest and in transit. The platform already encrypts data at rest by default. However, you are concerned about the data in transit from the EHR system. What should you do?
Encrypt the CSV file before uploading.
Why wrong: File encryption is not supported; use secure transfer.
Change the patient portal API to use batch uploads.
Why wrong: API is already secure.
Configure the EHR data source to use SFTP for file transfer.
Secures data in transit.
Enable double encryption at rest in Customer Insights.
Why wrong: Encryption at rest is not the issue.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure the EHR data source to use SFTP for file transfer.
Option C is correct because SFTP (SSH File Transfer Protocol) encrypts the CSV file during transit, addressing the concern about data in transit from the on-premises EHR system. Since the EHR sends data via a nightly batch file, using SFTP ensures the file is encrypted over the network, complementing the platform's default encryption at rest. This aligns with HIPAA requirements for protecting ePHI during transmission.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Encrypt the CSV file before uploading.
Why it's wrong here
File encryption is not supported; use secure transfer.
Change the patient portal API to use batch uploads.
Why it's wrong here
API is already secure.
Configure the EHR data source to use SFTP for file transfer.
Why this is correct
Secures data in transit.

Enable double encryption at rest in Customer Insights.
Why it's wrong here
Encryption at rest is not the issue.
Common exam traps
The trap here is that candidates may confuse encrypting the file itself (Option A) with securing the transfer channel, or assume that double encryption at rest (Option D) covers transit, when in fact HIPAA requires encryption both at rest and in transit, and the question specifically targets the transit vulnerability from the on-premises EHR system.
Detailed technical explanation
SFTP operates over SSH (port 22) and provides both authentication and encryption for file transfers, unlike FTP which transmits data in plaintext. In a healthcare scenario, using SFTP for batch CSV transfers ensures compliance with HIPAA's Security Rule (45 CFR § 164.312(e)(1)), which mandates encryption of ePHI in transit over open networks. The EHR system's nightly batch file is a classic use case where SFTP replaces insecure FTP or unencrypted HTTP transfers.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
