Azure Traffic Manager supports the following traffic-routing methods:
Priority
Weighted
Performance
Multivalue
Geographic
Subnet
Performance Routing is recommended when there are endpoints in various geographic locations.
You need end-users to utilize the "closest" endpoint for the minimum possible network latency.
Option A is incorrect. Priority traffic routing is recommended when you want to have a primary/main service endpoint for all traffic.
Option B is incorrect. The network is not a valid traffic routing method.
Option C is correct. Performance Routing is recommended when there are endpoints in various geographic locations. You need end-users to utilize the "closest" endpoint for the minimum possible network latency.
Option D is incorrect. Singlevalue is not a valid traffic routing method.
Option E is incorrect. Weighted routing is recommended when traffic is distributed all across a set of endpoints depending upon their weight.
