DP-203 Practice Question: Reviewing an Azure Policy assignment that uses…
Exhibit
Refer to the exhibit.
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "Microsoft.Storage/storageAccounts/listAccountSas/action",
"Resource": "/subscriptions/.../resourceGroups/.../providers/Microsoft.Storage/storageAccounts/stgacct"
}
]
}
```You are reviewing an Azure Policy assignment that uses the above JSON to define a role-based access control (RBAC) action. What is the primary purpose of this policy?
⚠ Common exam trap
Test-takers frequently confuse the account-level SAS generation action with container or blob-level delegation, or mistakenly think the policy itself assigns roles rather than defining a permission that can be used in a custom role.
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
✓
To authorize generation of a shared access signature (SAS) token for the storage account.
The policy JSON defines a role-based access control (RBAC) action that grants the 'Microsoft.Storage/storageAccounts/listAccountSas/action' permission. This specific action authorizes the generation of a shared access signature (SAS) token at the storage account level, not at the container or blob level. Therefore, the primary purpose is to allow the generation of an account SAS token, which provides delegated access to storage services.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To assign RBAC roles to users for the storage account.
Why it's wrong here
RBAC role assignment is done via 'Microsoft.Authorization/roleAssignments/write'.
- ✗
To enable delegation of access to a specific blob.
Why it's wrong here
Blob-level delegation requires 'Microsoft.Storage/storageAccounts/blobServices/containers/blobs' actions.
- ✗
To allow users to set permissions on storage account containers.
Why it's wrong here
Setting container permissions is done via different actions like 'container/update'.
- ✓
To authorize generation of a shared access signature (SAS) token for the storage account.
Why this is correct
The 'listAccountSas' action generates an account-level SAS token.
