What is one of the key features of the survey tool in Dynamics 365 for Marketing to limit response duplicity?

The key feature of the survey tool in Dynamics 365 for Marketing that helps to limit response duplicity is the restriction on multiple completions by non-anonymous respondents. This means that when participants are identified (non-anonymous), the system is configured to allow them to submit their responses only once. This is crucial for maintaining the integrity and accuracy of survey data, ensuring that each response accurately reflects a unique participant’s perspective and minimizing skewed results that could arise from multiple submissions by the same individual.

While other options may address different aspects of survey management, such as ensuring that submissions come from distinct email addresses or implementing expiration dates, it is the restriction on multiple completions for identifiable respondents that directly targets the issue of duplicate responses. This feature is vital for organizations wanting to collect genuine feedback and make informed decisions based on straightforward and reliable survey data.
