DP-300 Implement a secure environment Practice Question
This DP-300 practice question tests your understanding of implement a secure environment. 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.
Exhibit
Refer to the exhibit.
```json
{
"type": "Microsoft.Sql/servers/databases/transparentDataEncryption",
"apiVersion": "2022-05-01-preview",
"properties": {
"status": "Enabled"
}
}
```
Refer to the exhibit. You are deploying an Azure SQL Database with Transparent Data Encryption (TDE) enabled via ARM template. The database will contain highly sensitive data, and your security policy requires that the encryption key be managed by your organization using Azure Key Vault. What additional configuration is needed?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the 'keyVaultUri', 'keyName', and 'keyVersion' properties to reference the key in Key Vault
Option A is correct because when deploying Azure SQL Database with TDE and customer-managed keys (CMK) via ARM template, you must explicitly specify the 'keyVaultUri', 'keyName', and 'keyVersion' properties under the 'encryptionProtector' resource to link the database to the specific key in Azure Key Vault. Without these properties, the template would only enable TDE with a service-managed key, not the required customer-managed key.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Set the 'keyVaultUri', 'keyName', and 'keyVersion' properties to reference the key in Key Vault
Why this is correct
Required to use customer-managed keys for TDE.
Related concept
Read the scenario before looking for a memorised answer.
✗
No additional configuration is needed; the template already enables TDE with customer-managed keys
Why it's wrong here
The template enables TDE with service-managed keys only.
✗
Deploy a separate key rotation policy in the ARM template
Why it's wrong here
Key rotation is separate and not required for initial configuration.
✗
Enable 'autoRotationEnabled' property
Why it's wrong here
Auto-rotation is optional, not required.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume enabling TDE in the ARM template automatically uses customer-managed keys, but they overlook the need to explicitly configure the encryption protector with Key Vault properties to switch from service-managed to customer-managed keys.
Detailed technical explanation
How to think about this question
Under the hood, TDE with customer-managed keys uses the 'encryptionProtector' resource of type 'Microsoft.Sql/servers/encryptionProtector' with 'serverKeyType' set to 'AzureKeyVault'. The 'keyVaultUri', 'keyName', and 'keyVersion' properties are mandatory to establish the link to the specific key version in Key Vault; omitting them results in the default service-managed key. A real-world scenario is when a security audit requires proof that the database uses a specific key version from a managed HSM-backed Key Vault, and the ARM template must explicitly reference that version to pass compliance checks.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
