The answer is to apply a CanNotDelete lock to the resource group. This lock prevents the deletion of the resource group and all resources within it, including the critical virtual machine and storage account, while still allowing administrators to update settings and perform configuration changes. On the AZ-104 exam, this scenario tests your understanding of Azure resource locks, specifically the distinction between CanNotDelete and ReadOnly locks—a common trap is choosing ReadOnly, which would block the required updates. The key concept is that CanNotDelete locks protect against accidental deletion without restricting read or write operations, making them ideal for shared environments during routine maintenance. For a quick memory tip, remember that CanNotDelete means "can still edit, just can't delete"—think of it as a safety net that catches only the delete action.
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 critical virtual machine and a storage account. Administrators must still be able to update settings, but nobody should accidentally delete either resource during routine maintenance. Which lock should be applied?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
CanNotDelete lock on the resource group.
The CanNotDelete lock on the resource group prevents deletion of the resource group and all resources within it, while still allowing administrators to update settings. This meets the requirement of protecting both the critical VM and storage account from accidental deletion during routine maintenance, without blocking configuration changes.
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.
✗
ReadOnly lock on the resource group.
Why it's wrong here
ReadOnly prevents most write operations, which would interfere with normal maintenance and updates.
✓
CanNotDelete lock on the resource group.
Why this is correct
CanNotDelete blocks deletion while still allowing normal update operations on the resources.
Related concept
Read the scenario before looking for a memorised answer.
✗
A policy assignment that denies delete operations.
Why it's wrong here
Azure Policy is not the primary tool for preventing accidental deletion in this scenario.
✗
A management group assignment with Contributor removed.
Why it's wrong here
Removing broad permissions is not the same as applying a targeted deletion safeguard to the resource group.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Policy with resource locks, thinking a deny policy can prevent deletion, but locks are the only mechanism that directly blocks delete operations at the resource level regardless of RBAC permissions.

Detailed technical explanation
How to think about this question
Azure Resource Manager locks are applied at the resource, resource group, or subscription scope and are inherited by child resources. The CanNotDelete lock uses the `Microsoft.Authorization/locks` resource type and is enforced by Azure RBAC, meaning even users with Owner permissions cannot delete the resource unless the lock is first removed. This is distinct from Azure Policy, which uses `policyDefinitions` and `policyAssignments` to enforce rules but does not block actions at the resource provider level; locks are evaluated after RBAC authorization and before the resource provider processes the request.

→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

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.

Variation 1. A shared resource group contains a VPN gateway and several virtual machines used by the finance department. Administrators must still be able to resize the VMs and update NSG rules, but no one should be able to delete the resource group or anything in it during the quarter-end freeze. Which lock should be applied?
medium
A.ReadOnly lock on the resource group
✓ B.CanNotDelete lock on the resource group
C.Management group lock on the subscription
D.Azure Policy deny effect on the resource group
Why B: The CanNotDelete lock (option B) prevents deletion of the resource group and all resources within it, while still allowing read and update operations such as resizing VMs and modifying NSG rules. This meets the requirement to block deletions during the quarter-end freeze without hindering administrative changes. ReadOnly locks would block all write operations, including resizing and NSG rule updates, which is not desired.
