Your company plans to provision blob storage by using an Azure Storage account. The blob storage will be accessible from 20 application servers on the internet.
You need to recommend a solution to ensure that only the application servers can access the storage account.
What should you recommend using to secure the blob storage?

A. managed rule sets in Azure Web Application Firewall (WAF) policies

B. inbound rules in network security groups (NSGs)

C. firewall rules for the storage account

D. inbound rules in Azure Firewall

E. service tags in network security groups (NSGs)






 

Suggested Answer: C

Community Answer: C

Configure Azure Storage firewalls and virtual networks.
To secure your storage account, you should first configure a rule to deny access to traffic from all networks (including internet traffic) on the public endpoint, by default. Then, you should configure rules that grant access to traffic from specific VNets. You can also configure rules to grant access to traffic from selected public internet IP address ranges, enabling connections from specific internet or on-premises clients. This configuration enables you to build a secure network boundary for your applications.
Storage firewall rules apply to the public endpoint of a storage account. You don't need any firewall access rules to allow traffic for private endpoints of a storage account. The process of approving the creation of a private endpoint grants implicit access to traffic from the subnet that hosts the private endpoint.
Incorrect:
Not B: You can use an Azure network security group to filter network traffic to and from Azure resources in an Azure virtual network. A network security group contains security rules that allow or deny inbound network traffic to, or outbound network traffic from, several types of Azure resources. For each rule, you can specify source and destination, port, and protocol.
Not E: A service tag represents a group of IP address prefixes from a given Azure service. Microsoft manages the address prefixes encompassed by the service tag and automatically updates the service tag as addresses change, minimizing the complexity of frequent updates to network security rules.
