Actual exam question from Microsoft's AZ-700
Question #: 20
Topic #: 3
[All AZ-700 Questions]

HOTSPOT -
Your company has 10 instances of a web service. Each instance is hosted in a different Azure region and is accessible through a public endpoint.
The development department at the company is creating an application named App1. Every 10 minutes, App1 will use a list of endpoints and connect to the first available endpoint.
You plan to use Azure Traffic Manager to maintain the list of endpoints.
You need to configure a Traffic Manager profile that will minimize the impact of DNS caching.
What should you configure? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

he Multivalue traffic-routing method allows you to get multiple healthy endpoints in a single DNS query response. This configuration enables the caller to do client-side retries with other endpoints in case a returned endpoint being unresponsive. This pattern can increase the availability of a service and reduce the latency associated with a new DNS query to obtain a healthy endpoint. MultiValue routing method works only if all the endpoints of type ‘External’ and are specified as IPv4 or IPv6 addresses. When a query is received for this profile, all healthy endpoints are returned and are subject to a configurable maximum return count.

Your statement is correct. We know it's external endpoint due to the key word "...accessible through a public endpoint" https://docs.microsoft.com/en-us/azure/traffic-manager/traffic-manager-configure-multivalue-routing-method#add-traffic-manager-endpoint "At this time adding endpoints using IPv4 or IPv6 addresses is supported only for endpoints of type External and hence MultiValue routing is also supported only for such endpoints." Therefore the other endpoints including Azure endpoint are not an option. Simple process of elimination.

I have tested it in the Azure Portal. If you try to use Azure endpoint you get error ..."MultiValue profiles cannot have endpoint with domain names, Azure endpoints or nested endpoints as targets"

• Azure endpoints are used for services hosted in Azure. • External endpoints are used for services hosted outside Azure, either on-premises or with a different hosting provider. • Nested endpoints are used to combine Traffic Manager profiles to create more flexible traffic-routing schemes to support the needs of larger, more complex deployments. as per the following I assume we are talking about azure endpoints, not external endpoints

I think the answer is correct. Multivalue is the only option that will return the list of the endpoints, which is the requirement. However, you cannot use Azure endpoints with a multivalue routing algorithm and also you are reaching out to all the WebApps from the "outside".

The catch is that " minimize the impact of DNS caching" and when we select Multivalue it clearly says "MultiValue routing method works only if all the endpoints of type ‘External’ and are specified as IPv4 or IPv6 addresses"

i think it has to be azure end point, as the services are hosted in Azure Azure endpoints are used for services hosted in Azure. External endpoints are used for IPv4/IPv6 addresses, FQDNs, or for services hosted outside Azure. Theses services can either be on-premises or with a different hosting provider. Nested endpoints are used to combine Traffic Manager profiles to create more flexible traffic-routing schemes to support the needs of larger, more complex deployments.

"Instances are hosted in Azure but are accessible via public endpoints". Hence External endpoints.
