Explanation:

When using Salesforce Media Cloud in conjunction with Google Ad Manager (GAM) for ad order orchestration, much of the order lifecycle — such as campaign creation, line item setup, and inventory booking — can be automated via integration. However, there are still manual steps required in GAM by the Media Planner, particularly when it comes to managing creatives, which are assets (images, videos, or HTML) that will be displayed in ads.

✅ A. Check if creatives are loaded in GAM
Before a campaign can go live, the Media Planner must verify that the correct creatives have been uploaded into GAM. While orders and line items may be pushed from Salesforce automatically, creative files are not always handled via API and must often be uploaded or verified manually.

✅ C. Associate the creatives to a line item in GAM
Even if creatives are uploaded, they need to be manually associated with the specific line items in GAM. This assignment tells GAM which creative should run for which ad slot. This is another step that typically requires manual action from the Media Planner.

❌ Incorrect Answers:

B. Create order in GAM
This step is typically automated when using Salesforce Media Cloud with GAM. Once a media plan is approved in Salesforce, the integration can automatically push the order to GAM via API, eliminating the need for manual order creation.

D. Check availability of inventory in GAM
Inventory checks (e.g., forecasting availability) can also be automated through API calls from Salesforce to GAM. The availability results can be displayed in Salesforce during the media planning process, so the Media Planner does not need to manually log into GAM for this step.
