Zorluk: OrtaResource Locks

An Azure administrator configures a ReadOnly resource lock on a resource group named rg-finance. The resource group contains an Azure Virtual Network named vnet-prod. Another administrator then applies a CanNotDelete lock directly to vnet-prod. Which of the following statements describe the resulting effects of these locks? Select two.

  1. Users are prevented from adding a new subnet to vnet-prod.Cevap
  2. Users are prevented from deploying new resources into rg-finance.Cevap
  3. C
    Users can add a new subnet to vnet-prod because the directly applied CanNotDelete lock allows modification operations.
  4. D
    Users can deploy new resources into rg-finance as long as those resources do not have locks applied to them.

Cevap

Users are prevented from adding a new subnet to vnet-prod and users are prevented from deploying new resources into rg-finance.
The correct statements are that users are blocked from adding a subnet to the virtual network and blocked from deploying new resources to the resource group. This is because a ReadOnly lock is inherited by child resources, and when multiple locks exist, the most restrictive lock (ReadOnly) takes precedence over the less restrictive lock (CanNotDelete). A ReadOnly lock on a resource group also prevents any new resources from being created within that group.

Adım Adım Çözüm

1
Determine the inheritance of the resource locks.
The resource group rg-finance has a ReadOnly lock, which is inherited by all resources within it, including the virtual network vnet-prod.
Azure resource locks are inherited from parent scopes (subscriptions, resource groups) to child resources.
2
Evaluate the precedence when multiple locks apply.
vnet-prod has both an inherited ReadOnly lock and a direct CanNotDelete lock. The ReadOnly lock is more restrictive, so it takes precedence.
When multiple locks are applied, the most restrictive lock applies.
3
Determine the impact on resource modification and creation.
Adding a subnet to vnet-prod is blocked due to the active ReadOnly restriction. Additionally, creating new resources in rg-finance is blocked because the resource group itself has a ReadOnly lock.
A ReadOnly lock prevents all write and delete operations, including modifying resources and adding new resources to the locked scope.
