A risk reviewer is considering an Azure design that aims to: support centralized revocation without rotating the whole account key. Which limitation should still be documented?
Stored access policies apply to service SAS, not every SAS type, and their count is limited per container. That remains a practical service boundary even after the recommended change (associate service SAS signatures with a stored access policy on the container and update or remove that policy to revoke them) is implemented; retest it when identities, policies, service capacity or network paths change.
The successful check 'Delete or expire the policy and verify that same token no longer works' proves only the tested behavior and cannot eliminate every dependent failure. The specific remaining limitation is: Stored access policies apply to service SAS, not every SAS type, and their count is limited per container.
The two checks cover separate behavior: 'Delete or expire the policy and verify that same token no longer works' and 'Issue a policy-bound service SAS and prove it works before revocation'. Neither check removes the remaining operational limitation: Stored access policies apply to service SAS, not every SAS type, and their count is limited per container.
The incident (a retired project's service SAS remains functional even after the client is removed from the team roster) could recur if a related Azure dependency changes. The design still faces the limitation: Stored access policies apply to service SAS, not every SAS type, and their count is limited per container.
An Azure administrator must resolve a specific request: A vendor needs time-limited read access to a single exported blob and must not receive the storage account key. The expected outcome is: issue narrowly scoped delegated blob access that expires after the agreed window. Which option is appropriate?
A SAS can delegate limited operations without disclosing an account key to the external requester. This achieves issue narrowly scoped delegated blob access that expires after the agreed window through create a read-only SAS with appropriate expiry, HTTPS requirements and least-privileged resource scope instead of relying on merely similar resource settings.
Master keys confer broad rights beyond the named blob; that would not meet issue narrowly scoped delegated blob access that expires after the agreed window, for which the relevant Azure action is create a read-only SAS with appropriate expiry, HTTPS requirements and least-privileged resource scope.
The broad permissions exceed a single short-lived read-only delivery; that would not meet issue narrowly scoped delegated blob access that expires after the agreed window, for which the relevant Azure action is create a read-only SAS with appropriate expiry, HTTPS requirements and least-privileged resource scope.
Public access offers no recipient or expiry restriction; that would not meet issue narrowly scoped delegated blob access that expires after the agreed window, for which the relevant Azure action is create a read-only SAS with appropriate expiry, HTTPS requirements and least-privileged resource scope.
Operations sees an unexpected outcome: The vendor's token permits deletion and remains valid after the engagement ends. The original demand was: issue narrowly scoped delegated blob access that expires after the agreed window. Which cause is most consistent with the evidence?
The trace reports: The vendor's token permits deletion and remains valid after the engagement ends. The causal misconfiguration is: The SAS was generated with excessive permissions or an excessively long expiry. The targeted action is to regenerate a read-only scoped SAS with a short validity window and controlled HTTPS-only access.
The proposed mechanism concerns the vendor received a read-only SAS restricted to a short expiry, and all delete requests using it are denied, which is not established by the observed the vendor's token permits deletion and remains valid after the engagement ends. Test the more directly supported condition: The SAS was generated with excessive permissions or an excessively long expiry.
The ad hoc SAS tokens were not tied to a revocable stored access policy or relevant signing-key change; that mechanism would be more consistent with an observation such as a retired project's service SAS remains functional even after the client is removed from the team roster, rather than this case's the vendor's token permits deletion and remains valid after the engagement ends.
The storage firewall remains set to allow all networks or its approved ranges are too broad. That mechanism would be more consistent with an observation such as an unauthorized home IP can still reach the storage account public endpoint, rather than this case's the vendor's token permits deletion and remains valid after the engagement ends.
A service owner needs a practical fix after this failure: The vendor's token permits deletion and remains valid after the engagement ends. What is the best remediation?
Regenerate a read-only scoped SAS with a short validity window and controlled HTTPS-only access. This addresses the documented failure condition: the SAS was generated with excessive permissions or an excessively long expiry. Retest the affected operation and retain the original least-privilege boundaries.
The broad permissions exceed a single short-lived read-only delivery. In the reported incident (the vendor's token permits deletion and remains valid after the engagement ends), that change would not correct the cause: the SAS was generated with excessive permissions or an excessively long expiry.
Public access offers no recipient or expiry restriction. In the reported incident (the vendor's token permits deletion and remains valid after the engagement ends), that change would not correct the cause: the SAS was generated with excessive permissions or an excessively long expiry.

A deployment claims to meet: issue narrowly scoped delegated blob access that expires after the agreed window. The environment is: A vendor needs time-limited read access to a single exported blob and must not receive the storage account key. Which TWO test results would substantiate that claim? Select TWO answers.
Download the designated blob using only the delegated SAS URL. This supplies observed evidence for issue narrowly scoped delegated blob access that expires after the agreed window. It is not interchangeable with the second required check, attempt deletion and use the URL after expiry, verifying rejection, because that checks a separate success or failure boundary.
Attempt deletion and use the URL after expiry, verifying rejection. This supplies observed evidence for issue narrowly scoped delegated blob access that expires after the agreed window. It is not interchangeable with the second required check, download the designated blob using only the delegated SAS URL, because that checks a separate success or failure boundary.
A privileged administrator in a different subscription may succeed at 'Download the designated blob using only the delegated SAS URL' even though the intended caller fails. This does not prove the required behavior for download the designated blob using only the delegated sas url.
A release checklist recording 'Attempt deletion and use the URL after expiry, verifying rejection' is not evidence that the required operation actually succeeded or failed. To establish the correct result, the team must attempt deletion and use the URL after expiry, verifying rejection on the actual workload to prove its independent boundary.
A configured resource is not proof of live behavior. The required check must exercise download the designated blob using only the delegated SAS URL on the affected Azure deployment.
An infrastructure design was selected to meet: issue narrowly scoped delegated blob access that expires after the agreed window. What caveat remains relevant during operation?
A SAS is a bearer capability; possession can be forwarded, and scope/time controls do not prove the recipient's identity. That remains a practical service boundary even after the recommended change (create a read-only SAS with appropriate expiry, HTTPS requirements and least-privileged resource scope) is implemented; retest it when identities, policies, service capacity or network paths change.
The two checks cover separate behavior: 'Download the designated blob using only the delegated SAS URL' and 'Attempt deletion and use the URL after expiry, verifying rejection'. Neither check removes the remaining operational limitation: A SAS is a bearer capability; possession can be forwarded, and scope/time controls do not prove the recipient's identity.
The incident (the vendor's token permits deletion and remains valid after the engagement ends) could recur if a related Azure dependency changes. The design still faces the limitation: A SAS is a bearer capability; possession can be forwarded, and scope/time controls do not prove the recipient's identity.

The specific remaining limitation is: A SAS is a bearer capability; possession can be forwarded, and scope/time controls do not prove the recipient's identity.
During an Azure migration, consider this case: An internal app uses Azure Files over SMB, and employees should authenticate with domain identities rather than shared storage keys. The requirement is: enforce identity-based share access plus file-level authorization on the SMB path. Which change most directly satisfies the team?
Azure Files identity-based SMB access needs both a trusted identity path and permissions at the share and filesystem levels. This achieves enforce identity-based share access plus file-level authorization on the SMB path through configure a supported Azure Files identity source for SMB, appropriate share-level permissions and file/directory ACLs instead of relying on merely similar resource settings.
Control-plane Reader cannot replace share and NTFS-style permissions; that would not meet enforce identity-based share access plus file-level authorization on the SMB path, for which the relevant Azure action is configure a supported Azure Files identity source for SMB, appropriate share-level permissions and file/directory ACLs.
A shared key bypasses individual identity attribution and broadens access; that would not meet enforce identity-based share access plus file-level authorization on the SMB path, for which the relevant Azure action is configure a supported Azure Files identity source for SMB, appropriate share-level permissions and file/directory ACLs.
Blob permissions are separate from Azure Files SMB authorization; that would not meet enforce identity-based share access plus file-level authorization on the SMB path, for which the relevant Azure action is configure a supported Azure Files identity source for SMB, appropriate share-level permissions and file/directory ACLs.
After a deployment the owner reports: Employees can reach the SMB endpoint but are denied access to a protected directory despite having a share role. Which diagnosis should the administrator verify before making unrelated changes?
The trace reports: Employees can reach the SMB endpoint but are denied access to a protected directory despite having a share role. The causal misconfiguration is: The file or directory ACL or identity configuration does not grant the effective SMB permission. The targeted action is to correct the required share-level role and file/directory ACL for the authenticated user or group.
The proposed mechanism concerns only ARM resource-reading rights were granted to the identity, not the blob data-plane permission, which is not established by the observed employees can reach the SMB endpoint but are denied access to a protected directory despite having a share role. Test the more directly supported condition: The file or directory ACL or identity configuration does not grant the effective SMB permission.
The ad hoc SAS tokens were not tied to a revocable stored access policy or relevant signing-key change; that mechanism would be more consistent with an observation such as a retired project's service SAS remains functional even after the client is removed from the team roster, rather than this case's employees can reach the SMB endpoint but are denied access to a protected directory despite having a share role.

An administrator has isolated a problem: Employees can reach the SMB endpoint but are denied access to a protected directory despite having a share role. What should be changed to correct it without unnecessary redesign?
Correct the required share-level role and file/directory ACL for the authenticated user or group. This addresses the documented failure condition: the file or directory ACL or identity configuration does not grant the effective SMB permission. Retest the affected operation and retain the original least-privilege boundaries.
A shared key bypasses individual identity attribution and broadens access. In the reported incident (employees can reach the SMB endpoint but are denied access to a protected directory despite having a share role), that change would not correct the cause: the file or directory ACL or identity configuration does not grant the effective SMB permission.
Blob permissions are separate from Azure Files SMB authorization. In the reported incident (employees can reach the SMB endpoint but are denied access to a protected directory despite having a share role), that change would not correct the cause: the file or directory ACL or identity configuration does not grant the effective SMB permission.

The owner requests release evidence for: enforce identity-based share access plus file-level authorization on the SMB path. Given this case: An internal app uses Azure Files over SMB, and employees should authenticate with domain identities rather than shared storage keys. Which TWO checks test the intended boundary? Select TWO answers.
Mount the share as an entitled user and read the approved folder. This supplies observed evidence for enforce identity-based share access plus file-level authorization on the SMB path. It is not interchangeable with the second required check, test an unentitled user against the same path and confirm access is denied, because that checks a separate success or failure boundary.

It is not interchangeable with the second required check, mount the share as an entitled user and read the approved folder, because that checks a separate success or failure boundary.
A release checklist recording 'Test an unentitled user against the same path and confirm access is denied' is not evidence that the required operation actually succeeded or failed. To establish the correct result, the team must test an unentitled user against the same path and confirm access is denied on the actual workload to prove its independent boundary.
A configured resource is not proof of live behavior. The required check must exercise mount the share as an entitled user and read the approved folder on the affected Azure deployment.
A privileged administrator in a different subscription may succeed at 'Mount the share as an entitled user and read the approved folder' even though the intended caller fails. This does not prove the required behavior for mount the share as an entitled user and read the approved folder.
The cloud team needs a bounded claim about: enforce identity-based share access plus file-level authorization on the SMB path. Which statement avoids promising more than the control supplies?
Share-level access alone does not override more restrictive file or directory ACLs. That remains a practical service boundary even after the recommended change (configure a supported Azure Files identity source for SMB, appropriate share-level permissions and file/directory ACLs) is implemented; retest it when identities, policies, service capacity or network paths change.
The incident (employees can reach the SMB endpoint but are denied access to a protected directory despite having a share role) could recur if a related Azure dependency changes. The design still faces the limitation: Share-level access alone does not override more restrictive file or directory ACLs.
The successful check 'Mount the share as an entitled user and read the approved folder' proves only the tested behavior and cannot eliminate every dependent failure. The specific remaining limitation is: Share-level access alone does not override more restrictive file or directory ACLs.
