DP-300 Implement a secure environment Practice Question
Exhibit
Refer to the exhibit.
```json
{
"role": "Azure SQL Database Contributor",
"scope": "/subscriptions/12345/resourceGroups/ProdRG/providers/Microsoft.Sql/servers/prodserver/databases/proddb",
"assignee": "user@contoso.com",
"condition": "((!(ActionMatches{'Microsoft.Sql/servers/databases/read'})) OR (@Request[Microsoft.Sql/servers/databases/read:DataAction] NotExists))",
"conditionVersion": "2.0"
}
```Refer to the exhibit. The exhibit shows an Azure role assignment with a condition. When user@contoso.com tries to read data from the database 'proddb', what will be the effect of this condition?
⚠ Common exam trap
Many candidates assume a condition only restricts certain operations or that metadata reads are separate from data reads, but Azure RBAC deny assignments unconditionally block the specified action, and 'read data' encompasses all data retrieval operations on the database.
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
✓
The user will be denied the ability to read data from the database.
The condition in the Azure role assignment explicitly denies read access to the database 'proddb' for user@contoso.com. In Azure RBAC, a deny assignment overrides any allow assignments, so even if the user has other roles granting read permissions, this condition will block all data read operations on that specific database. Therefore, the user will be denied the ability to read data from the database.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The user will be allowed to read all data from the database.
Why it's wrong here
The condition actually denies read data actions, not allows them.
- ✓
The user will be denied the ability to read data from the database.
Why this is correct
The condition denies read data actions because it excludes the data read action from the role.
- ✗
The user will be able to read the database metadata but not the data.
Why it's wrong here
The condition affects data read, not metadata read.
- ✗
The user will be able to assign the role to others.
Why it's wrong here
The condition does not affect role assignment permissions.
