Zorluk: OrtaConfigure Storage Account Network Access

You have an Azure subscription that contains a virtual network named VNet1 and a storage account named stcorpdata. You need to configure secure private access to the storage account from VNet1 using a private endpoint. The solution must ensure that resources in VNet1 can resolve the storage account's FQDN to its private IP address. Which sequence of steps should you perform to complete the configuration?

  1. 1Create a private DNS zone named privatelink.blob.core.windows.net.
  2. 2Link the private DNS zone to the virtual network VNet1.
  3. 3Create a private endpoint for the storage account's blob sub-resource in VNet1.
  4. 4Configure private DNS integration to register the private endpoint's IP address in the private DNS zone.
  5. 5Configure the storage account's public network access to Disabled.

Cevap

To configure secure private access to the storage account, you must first create the private DNS zone, link the zone to the virtual network, create the private endpoint, integrate it with the DNS zone to auto-register DNS records, and finally restrict the storage account's public network access.
The correct order establishes the prerequisite DNS infrastructure (creating the private DNS zone and linking it to the virtual network) before creating the private endpoint and integrating it. Finally, public access is disabled to restrict all traffic to the private network route.

Adım Adım Çözüm

1
Create a private DNS zone named privatelink.blob.core.windows.net.
The DNS namespace for the private endpoint is established in the subscription.
You must create the private DNS zone first so that it can be linked to virtual networks and receive DNS records.
2
Link the private DNS zone to VNet1.
VMs in VNet1 are configured to query the private DNS zone for name resolution.
Without linking the zone to the VNet, resources in the VNet will be unable to resolve the private DNS zone records.
3
Create a private endpoint for the blob service of stcorpdata in VNet1.
A private IP address is allocated to the storage account within the VNet subnet.
The private endpoint must be created to establish a private network interface for the storage service.
4
Configure private DNS integration with the private DNS zone.
A DNS A record is registered mapping stcorpdata.privatelink.blob.core.windows.net to the private endpoint's IP address.
DNS integration ensures that clients can resolve the storage account's public endpoint FQDN to the private IP address.
5
Set the public network access of the storage account to Disabled.
Public internet traffic to the storage account is blocked, and access is restricted to private endpoints only.
This locks down the storage account to complete the security configuration once private connectivity is confirmed.
