- A
Disable shared key access on the storage account.
Disabling shared key access prevents new requests from authenticating with account keys while leaving Entra-based access available.
- B
Assign the managed identity a data-plane role such as Storage Blob Data Reader.
The managed identity still needs a valid RBAC data role so it can continue reading blobs after key access is blocked.
- C
Replace the managed identity with a storage account key in the app settings.
Why wrong: Using a storage account key would violate the requirement to avoid secrets and would re-enable shared-key dependence.
- D
Remove all network rules from the storage account.
Why wrong: Network rules affect reachability, not authentication method, so they do not block shared key authorization.
- E
Create a service SAS and embed it in the code.
Why wrong: A service SAS still relies on shared key infrastructure and is not aligned with the goal of removing secret-based access.
Quick Answer
The correct answer is to disable shared key access on the storage account and assign the managed identity a data-plane role like Storage Blob Data Reader. Disabling shared key authorization forces the storage account to reject any requests signed with account keys or SAS tokens, which directly blocks the insecure access method while still allowing Azure AD authentication. The managed identity, already used by the web app, seamlessly authenticates via Azure AD without needing any stored secrets, so the app continues to read blobs uninterrupted. On the AZ-104 exam, this scenario tests your understanding of the “Allow storage account key access” toggle under the storage account’s Configuration blade, and the common trap is thinking you only need to disable shared key access without also granting the managed identity the correct RBAC role. Remember the two-step rule: turn off the key, then assign the role. A useful mnemonic is “Key off, role on” to ensure both changes are made.
AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A web app already reads blobs by using a managed identity. Security now requires blocking any future requests that use shared key authorization, while the app must continue to work without storing secrets. Which two changes should the administrator make? Select two.
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
Disable shared key access on the storage account.
Option A is correct because disabling shared key access on the storage account enforces the security requirement to block future requests that use shared key authorization. This setting, when enabled, rejects any request that does not use Azure AD authentication, such as those signed with storage account keys or SAS tokens. Since the web app already uses a managed identity, it can continue to authenticate via Azure AD without storing secrets, ensuring the app works seamlessly after the change.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think disabling shared key access will break the app, but they overlook that a managed identity with the correct RBAC role can authenticate via Azure AD, so the app continues to work without shared keys or secrets.
Detailed technical explanation
How to think about this question
When shared key access is disabled on a storage account, the Azure Storage service rejects any request that does not include an OAuth 2.0 token from Azure AD, effectively blocking all shared key and SAS-based requests. The managed identity, once assigned a data-plane role like Storage Blob Data Reader, obtains an Azure AD token via the Azure Instance Metadata Service (IMDS) endpoint at 169.254.169.254, which the web app can use to authenticate without any stored secrets. This approach aligns with the principle of zero-trust security by eliminating static credentials and relying on role-based access control (RBAC) for authorization.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
