Quick Answer
The correct answer includes enabling a resource lock on the Azure SQL Database logical server and setting the minimum TLS version to 1.2, along with enabling Transparent Data Encryption (TDE). Setting the minimum TLS version to 1.2 enforces encryption in transit by rejecting all connections using older, insecure protocols, ensuring that every query sent to the database is encrypted over the network. This directly satisfies the security policy requirement for encrypted data in transit, while a resource lock prevents accidental deletion of the logical server, and TDE protects data at rest. On the DP-300 exam, this question tests your understanding of layered security controls—network, access, and data protection—and often includes a trap where candidates confuse encryption in transit (TLS) with encryption at rest (TDE). A useful memory tip is “TLS for travel, TDE for storage, lock for loss.”
This DP-300 practice question tests your understanding of plan and implement data platform resources. 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.
Your company is deploying Azure SQL Database for a new application. The security policy requires that all queries be encrypted in transit and that the database be protected against accidental deletion. Which THREE configurations should you implement? (Select THREE.)
Set the minimum TLS version to 1.2
Ensures encrypted connections.
Configure firewall rules to allow only specific IP addresses
Why wrong: Firewall does not enforce encryption.
Enable Microsoft Entra ID authentication
Why wrong: Entra ID is for authentication, not encryption.
Enable Transparent Data Encryption (TDE)
Encrypts data at rest.
Enable a resource lock on the Azure SQL Database logical server
Prevents accidental deletion.

Correct answer & explanation
Set the minimum TLS version to 1.2
Setting the minimum TLS version to 1.2 ensures that all connections to Azure SQL Database use a secure, encrypted channel, enforcing encryption in transit as required by the security policy. TLS 1.2 is the minimum recommended version, as older versions (1.0, 1.1) are deprecated and vulnerable to attacks like POODLE and BEAST.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse encryption in transit (TLS) with encryption at rest (TDE) or access control (firewall rules, Entra ID), and overlook the resource lock as a separate, required configuration for deletion protection.
Detailed technical explanation
TLS 1.2 uses cipher suites like TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 to provide forward secrecy and strong encryption. Resource locks, when set to 'CanNotDelete' or 'ReadOnly', prevent accidental deletion at the Azure Resource Manager level, overriding any delete permissions. TDE encrypts data at rest using AES-256, ensuring that physical database files are encrypted on disk, which is separate from in-transit encryption.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
