If your property is integrated with both Display & Video 360 and Campaign Manager and auto-tagging is enabled, what will be the source/medium for sessions from Display & Video 360?

When Google Analytics 360 is integrated with both Display & Video 360 (DV360) and Campaign Manager (CM), and auto-tagging is enabled, the source/medium for DV360 traffic is dbm / cpm. Here's why: dbm: This is the standard source identifier for Display & Video 360 (formerly DoubleClick Bid Manager). cpm: This is the standard medium identifier for cost-per-thousand (CPM) advertising, which is a common pricing model in DV360. The other options are incorrect because: dcm-dbm / cpm and dfa-dbm / cpm are not the correct, concise source identifiers used by Google Analytics for DV360 traffic. While dcm (DoubleClick Campaign Manager) and dfa (DoubleClick Floodlight Activities) are related to the ecosystem, dbm specifically denotes DV360. dfa / cpm would incorrectly attribute the source solely to Floodlight Activities rather than the DV360 platform itself.
