The correct way to structure the Campaign Manager 360 instances when an advertising agency adds several clients across different categories is to create an agency account with multiple advertisers within that account to ensure easy transferability.

• You should create several networks, with one for each of the clients.
• You should create multiple campaigns for each account you work with within the agency.
• You should create multiple campaigns, with one for each client.
• You should create an agency account with multiple advertisers within the account.

The correct answer is: You should create an agency account with multiple advertisers within the account.

Explanation: The answer “You should create an agency account with multiple advertisers within the account” is correct.

Structuring Campaign Manager 360 with a single agency account and individual advertisers for each client, regardless of their category, ensures simple transferability. This hierarchical setup centralizes agency-level administration while maintaining distinct data silos for each client within their respective advertisers. If a client relationship ends, their entire advertiser account, including campaigns and historical data, can be easily transferred to another agency’s CM360 instance without affecting other clients or requiring complex data migration. This structure streamlines client management and facilitates smooth transitions.
