HOTSPOT You need to configure a new Azure App Service app named WebApp1. The solution must meet the following requirements: WebApp1 must be able to verify a custom domain name of app.contoso.com. WebApp1 must be able to automatically scale up to eight instances. Costs and administrative effort must be minimized. Which pricing plan should you choose, and which type of record should you use to verify the domain? To answer, select the appropriate options in the answer area.

To meet the requirements, the Standard App Service plan is the most appropriate choice.

The Free, Shared, and Basic tiers do not support the required autoscale capability of up to

eight instances. While Premium and Isolated tiers also meet the technical requirements, the

Standard plan is the most cost-effective option that satisfies all conditions, thereby

minimizing costs.

For domain verification, a TXT record is used. Azure provides a unique Domain Verification

ID that must be added as a TXT record to your domain's DNS settings. This process proves

to Azure that you have ownership of the custom domain before it can be associated with the

App Service app. While a CNAME record is used to map a subdomain, the TXT record is a

primary method specifically for the verification step.

Azure App Service pricing tiers: The official Azure documentation details the

features available in each App Service plan. The "App Service pricing" page shows

that the Standard plan is the first tier to include autoscale capabilities up to 10

instances and support for custom domains.

Custom domain verification: The official tutorial for mapping a custom domain to

an App Service app explicitly describes using a TXT record for domain ownership

verification.

DNS name to Azure App Service"

o Specific Section: In the "Get a domain verification ID" and "Create the DNS

records" sections, the procedure outlines creating a TXT record (asuid.your-

subdomain) with the verification ID as its value.
