- A
A ReadOnly lock on the entire resource group.
Why wrong: ReadOnly would block normal updates and patching, which conflicts with the requirement to continue making changes.
- B
A CanNotDelete lock on each resource.
CanNotDelete prevents deletion while still allowing updates, and applying it per resource limits collateral impact.
- C
A policy assignment that denies delete operations on the resource group.
Why wrong: Azure Policy is not the right control for simple deletion protection when a lock is available and more direct.
- D
A management group with a deny assignment.
Why wrong: Management groups organize subscriptions and governance, but they are not the most precise control for protecting two resources in one group.

AZ-104 Manage Azure Identities and Governance Practice Question
This AZ-104 practice question tests your understanding of manage azure identities and governance. 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.
A shared resource group contains a VM and a storage account used by payroll. Administrators still need to modify configuration and apply patches, but accidental deletion of either resource must be prevented. What should the administrator apply?
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
✓
A CanNotDelete lock on each resource.
Option B is correct because a CanNotDelete lock prevents the deletion of a resource while still allowing all other operations, including configuration modifications and patching. This meets the requirement of protecting the VM and storage account from accidental deletion while preserving administrative access for updates.
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.
- ✗
A ReadOnly lock on the entire resource group.
Why it's wrong here
ReadOnly would block normal updates and patching, which conflicts with the requirement to continue making changes.
When this WOULD be correct
A ReadOnly lock on the entire resource group would be correct if the requirement was to prevent any changes to resources, such as in a production environment where no modifications are allowed, and only read access is needed for auditing or reporting.
- ✓
A CanNotDelete lock on each resource.
Why this is correct
CanNotDelete prevents deletion while still allowing updates, and applying it per resource limits collateral impact.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
A policy assignment that denies delete operations on the resource group.
Why it's wrong here
Azure Policy is not the right control for simple deletion protection when a lock is available and more direct.
When this WOULD be correct
This option would be correct if the question asked to prevent deletion of the entire resource group while still allowing deletion of individual resources (e.g., to protect the group structure but allow resource lifecycle management).
- ✗
A management group with a deny assignment.
Why it's wrong here
Management groups organize subscriptions and governance, but they are not the most precise control for protecting two resources in one group.
When this WOULD be correct
An administrator needs to prevent deletion of all resources across multiple subscriptions under a management group, while still allowing configuration changes. A deny assignment at the management group scope would enforce this restriction at a higher level.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓A CanNotDelete lock on each resource.Correct answer▾
Why this is correct
CanNotDelete prevents deletion while still allowing updates, and applying it per resource limits collateral impact.
✗A ReadOnly lock on the entire resource group.Wrong answer — click to see why▾
Why this is wrong here
A ReadOnly lock prevents all modifications, including patching and configuration changes, which are still required by administrators. The question explicitly states that administrators need to modify configuration and apply patches, so a ReadOnly lock is too restrictive.
★ When this WOULD be the correct answer
A ReadOnly lock on the entire resource group would be correct if the requirement was to prevent any changes to resources, such as in a production environment where no modifications are allowed, and only read access is needed for auditing or reporting.
Why candidates choose this
Candidates may think a ReadOnly lock is a simple way to prevent deletion, overlooking that it also blocks modifications, which are explicitly needed in this scenario.
✗A policy assignment that denies delete operations on the resource group.Wrong answer — click to see why▾
Why this is wrong here
A policy assignment that denies delete operations on the resource group does not prevent deletion of individual resources within the group; it only prevents deletion of the resource group itself. The question requires preventing deletion of the VM and storage account, not the group.
★ When this WOULD be the correct answer
This option would be correct if the question asked to prevent deletion of the entire resource group while still allowing deletion of individual resources (e.g., to protect the group structure but allow resource lifecycle management).
Why candidates choose this
Candidates may think a policy can enforce a blanket deny on all delete operations within the scope, but policies at the resource group level do not automatically apply to child resources unless explicitly defined with appropriate effect and scope.
✗A management group with a deny assignment.Wrong answer — click to see why▾
Why this is wrong here
A management group with a deny assignment would apply to multiple subscriptions, not just the single resource group. It is overly broad and does not target the specific resources (VM and storage account) within that resource group.
★ When this WOULD be the correct answer
An administrator needs to prevent deletion of all resources across multiple subscriptions under a management group, while still allowing configuration changes. A deny assignment at the management group scope would enforce this restriction at a higher level.
Why candidates choose this
Candidates may confuse management groups with resource groups or think that a deny assignment is a more powerful version of a lock, not realizing it applies at a broader scope and requires Azure RBAC permissions.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse resource locks with Azure Policy or RBAC, mistakenly thinking a policy or role assignment at the resource group scope will protect individual resources, when in fact locks must be applied directly to each resource to prevent its deletion.
Detailed technical explanation
How to think about this question
Azure resource locks operate at the Azure Resource Manager (ARM) control plane layer, using the `Microsoft.Authorization/locks` resource type. A CanNotDelete lock is implemented as a `CanNotDelete` role assignment that denies the `Microsoft.Resources/subscriptions/resourceGroups/resources/delete` action, but it still allows read, write, and other operations. Under the hood, locks are inherited by child resources but not by sibling resources, so applying a lock on the resource group would protect the group itself but not the VM or storage account individually unless they are explicitly locked.
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.
