Explanation

Analysis of Correct Answer(s)

The most logical and immediate first step is to examine the campaign trafficking settings. This is because placements within Campaign Manager 360 control where ads can be delivered. By checking the trafficking settings, specifically the placement compatibility and environment targeting, the client can verify if the campaign is currently configured to serve on mobile web and in-app environments. This initial check provides a clear picture of the current setup before any changes are made. It directly addresses the need to "make sure of delivery" on mobile.

Analysis of Incorrect Options

  • Configure their account: This is too broad. Account-level settings are foundational, but the question concerns an existing campaign. The issue is more likely with the specific campaign's or placement's targeting rather than the entire account configuration.
  • Modify their existing campaign: This is an action to be taken after an initial check. The question asks for the first thing to check. You must first examine the settings to understand what, if anything, needs to be modified.
  • Set up campaign creatives for mobile-friendly sizes: The question states that some creatives are already mobile-optimized. While ensuring all creatives are suitable is important, it's not the first step. If the placement settings don't allow mobile delivery, having mobile-friendly creatives is irrelevant as they won't serve. The delivery settings are the primary gatekeeper.
