Exam AZ-104 topic 3 question 71 discussion

ChatGPT: No, you cannot change the default routing tier of a storage account after creating a Premium File Share for it. Explanation: The routing preference for a storage account (e.g., Microsoft network routing or Internet routing) is generally configurable at the time of creating the storage account. However: Premium File Shares use the Microsoft network by default to optimize performance and low-latency access. Once a Premium File Share is created for a storage account, the routing preference becomes locked to the Microsoft network, and you cannot change it to Internet routing. If you need to use a different routing tier, you'll need to create a new storage account with the desired routing preference and configure it accordingly. Let me know if you need help setting up or managing this configuration!

You can't change Network Routing type if you create Premium File Shares, is just grayed out. You can change Network Routing type only if you create Premium Block Blob or Page Blobs. You can change performance of created File Share on the right side by clicking on 3 point and then choose "Change size and performance"

Correct Answer 1. Performance - if you see the exhibit storage is not created. so to minimize cost of accessing you can change the performance. 2. Encryption type enable infrastructure encryption and premium account type is only changeable when you creating storage which eliminate this options here. Enable support for Customer-managed keys is also not applied on this storage because storage is created by selecting Microsoft managed keys.

Encryption type is the correct answer for the second one, your reasoning is correct, but you ,is read the question.

Minimize network cost - Default routing tier to Internet Routing seems like the correct option as per answer above. Good idea to read through the article just once: https://learn.microsoft.com/en-us/azure/storage/common/network-routing-preference

I agree with 'wasilak' about the answers. Also, the links shared by him offers the correct answers, read them carefully. "Configuring routing preference gives you the flexibility to optimize your traffic either for premium network performance or for cost." "When you configure customer-managed keys for a storage account, Azure Storage wraps the root data encryption key for the account with the customer-managed key in the associated key vault or managed HSM. The protection of the root encryption key changes, but the data in your Azure Storage account remains encrypted at all times. There is no additional action required on your part to ensure that your data remains encrypted. Protection by customer-managed keys takes effect immediately. You can switch between customer-managed keys and Microsoft-managed keys at any time."

Everyone who answered "1. Default routing tier" for the first box, try creating a storage account with the specified settings. In the "Routing preference" section, the "Internet routing" option is greyed out and inactive. Additionally, it's not possible to change the Endpoint type — this setting is not available. Unfortunately, I couldn't find a suitable answer for myself.
