Your company has an Azure subscription that contains the following unused resources:
-> 20 user accounts in Azure Active Directory (Azure AD)
-> Five groups in Azure AD
-> 10 public IP addresses
-> 10 network interfaces
You need to reduce the Azure costs for the company.
Solution: You remove the unused network interfaces.
Does this meet the goal?

A. B.B
You are not charged for unused network interfaces. Therefore, deleting unused network interfaces will not reduce the Azure costs for the company.
https://docs.microsoft.com/en-us/azure/advisor/advisor-cost-recommendations#reduce-costs-by-deleting-or-reconfiguring-idle-virtual-network-gatewaysThe solution provided, which is to remove the unused network interfaces, does contribute to reducing Azure costs, but it may not be sufficient on its own to fully meet the goal of cost reduction for the company.
Here's a breakdown of the resources mentioned and their potential impact on costs:
User accounts in Azure AD: User accounts in Azure AD do not directly incur costs. However, if these user accounts have associated licenses (such as Azure AD Premium licenses), there might be associated costs. Removing unused user accounts can help avoid unnecessary license costs.
Groups in Azure AD: Similar to user accounts, groups in Azure AD do not have direct costs associated with them. However, they play a role in managing access and permissions for resources. It's important to review the group memberships and ensure that they are optimized and not granting unnecessary access to resources.
Public IP addresses: Public IP addresses typically have associated costs, especially if they are allocated but not in use. By identifying and releasing unused public IP addresses, you can reduce costs.
Network interfaces: Network interfaces are resources that facilitate network connectivity for virtual machines and other Azure resources. Unused network interfaces may indicate resources that have been decommissioned or are no longer needed. Removing them can help reduce costs associated with their provisioned network bandwidth.
Based on the information provided, removing the unused network interfaces is a step in the right direction for cost reduction. However, it's advisable to also review and consider removing any unused user accounts, release unused public IP addresses, and optimize group memberships to further reduce costs.
Therefore, the correct answer would be: B. No (Removing only the unused network interfaces is not sufficient to fully meet the goal of cost reduction. Additional actions, such as removing unused user accounts, releasing unused public IP addresses, and optimizing group memberships, should also be considered.)
The proposed solution to reduce Azure costs for the company is to remove the unused network interfaces.
Network interfaces (NICs) are used to attach a virtual machine to a virtual network, and they provide connectivity to other Azure services and the internet. If there are unused NICs in the Azure subscription, they are not serving any purpose, and hence removing them should not cause any issues with the functioning of the virtual machines or other services. Removing unused resources, in general, is a good practice as it helps to reduce clutter and complexity and may also result in cost savings.
However, it is important to note that the solution only addresses the unused NICs and not the other unused resources that are also present in the Azure subscription. There are 20 unused user accounts and five unused groups in Azure AD, and it is not clear whether these resources are needed or not. Additionally, there are 10 unused public IP addresses that may also be candidates for removal. Therefore, removing only the unused NICs may not be sufficient to achieve the goal of reducing Azure costs for the company.
In conclusion, while removing unused NICs is a good practice and may result in some cost savings, it may not be sufficient to meet the goal of reducing Azure costs for the company if there are other unused resources that are also present in the Azure subscription.
