AZ-700 Question 17
Select 2You administer the Azure environment for a multinational organization that wants to bring its own public IP addresses (BYOIP) to Azure for a critical application. These IP addresses are currently used on-premises, and you have verified you own them. You need to plan for a custom public IP address prefix in Azure. Which two steps must you complete prior to successfully onboarding your IP addresses to Azure?
- A
Obtain and submit a Letter of Authorization (LOA) from the appropriate Internet registry validating your ownership of the IP addresses.
- B
Wait for Azure to automatically migrate all your existing on-premises routes without requiring any user intervention.
- C
Submit a Bring Your Own IP (BYOIP) request through the Azure Portal or PowerShell/CLI, providing the required LOA as part of the process.
- D
Set the IP address prefix as the default route in your Azure virtual networks before receiving any validation from Microsoft.
Show answer and explanation
Correct answers: A, C
Explanation
To bring your own IP addresses to Azure (BYOIP), you must verify and prove ownership of your IP ranges. The typical process includes obtaining and submitting a Letter of Authorization (LOA) from the relevant registry, then creating a BYOIP request in the Azure Portal, PowerShell, or CLI. Once validated by Microsoft, you can create a custom public IP prefix in Azure and associate it with your services. Refer to Microsoft� official documentation (https://learn.microsoft.com/azure/virtual-network/ip-services/public-ip-address-prefix#bring-your-own-ip-byoip) for the detailed BYOIP steps and requirements.
- A. Correct.
Correct. Microsoft requires proof of ownership of the IP range. A Letter of Authorization (LOA) from your Regional Internet Registry (RIR) or equivalent authority validates your right to use and advertise these addresses in Azure.
- B. Incorrect.
Incorrect. Azure cannot automatically migrate your on-premises routes or addresses without user involvement. You must validate ownership and submit a BYOIP request first.
- C. Correct.
Correct. After obtaining the LOA, you must submit a BYOIP request in Azure. This process includes providing the LOA and awaiting validation before finalizing the custom public IP prefix.
- D. Incorrect.
Incorrect. You cannot use the custom IP prefix as a default route in your networks before Microsoft confirms that the prefix passes validation. Attempting to route traffic prematurely would result in routing conflicts and potential downtime.
