AZ-204 Certification Practice Question #112

Question

You have a static website hosted in an Azure Storage account named storage1. You access the website by using a URL that ends with the web.core.windows.net suffix.

You plan to configure the website to be accessible through the URL www.contoso.com. The website must be accessible during configuration.

The contoso.com zone is hosted in Azure DNS.

You need to complete the website configuration.

Which four actions should you perform in sequence? To answer, move the appropriate domain name configuration steps from the list of domain name configuration steps to the answer area and arrange them in the correct order.

Accepted Answer

The requirement for zero downtime (website must stay accessible during configuration) mandates the "asverify" CNAME pre-validation technique. The MS Learn article "Map a custom domain with zero downtime" documents exactly four steps: (1) identify the storage endpoint host name, (2) create the asverify CNAME in DNS to pre-validate ownership without disrupting traffic, (3) register the custom domain on the storage account, and (4) create the live www CNAME pointing to the storage endpoint. Community commenters c75e123 and 21c5438 both confirm this order and the zero-downtime rationale. The "Create an A record asverify" distractor is eliminated because CNAME-based mapping does not use A records.
