Explanation:
There are four traffic routing methods available in Traffic Manager:
App 1: Priority
Select Priority when you want to use a primary service endpoint for all traffic, and provide backups in case the primary or the backup endpoints are unavailable.
App2: Weighted
Select Weighted when you want to distribute traffic across a set of endpoints, either evenly or according to weights, which you define.
App3: Performance:
Select Performance when you have endpoints in different geographic locations and you want end users to use the "closest" endpoint in terms of the lowest network latency.
Note: 4th option is Geographic: Select Geographic so that users are directed to specific endpoints (Azure, External, or Nested) based on which geographic location their DNS query originates from.
