If your company used Reach Planner to forecast an awareness Video campaign, how should you set up the Video campaign to achieve similar reach to your media plan?

The correct answer is to ensure the frequency cap in your Video campaign matches the frequency cap set in Reach Planner. Reach Planner provides forecasts based on specific settings, including frequency. To achieve similar reach to your media plan, you must replicate those settings in your actual campaign. If the frequency cap differs, the actual reach will likely deviate from the forecast. Using Reach Planner from Google Analytics is not an option; it's a separate tool. Including keywords is for targeting, not for aligning with Reach Planner's reach forecasts. Using Reach Planner after a campaign is active is for analysis, not for initial setup alignment.
