Final answer:
Among the roles listed, 'sn_customerservice.consumer_agent' is the one that cannot update a consumer's record in the ServiceNow platform, as this role is likely designed with restricted access compared to the other roles which have more privileges.
Step-by-step explanation:
The roles that cannot update a consumer's record among the ones listed is: sn_customerservice.consumer_agent. The roles of sn_customerservice_agent, sn_customerservice_manager, and admin generally have more privileges and are typically allowed to make updates to records. This is designed within the ServiceNow platform which is a popular enterprise service management software. Each role has a specific set of permissions which determines what actions they can perform within the system.
In ServiceNow, the admin role usually has the highest level of privileges, including the ability to modify any data or configuration. The sn_customerservice_manager would typically have managerial level permissions, which can include updating consumer records. The sn_customerservice_agent is usually given sufficient permissions to update records as part of their customer service duties. However, the sn_customerservice.consumer_agent role is likely designed with more restricted access, possibly to view records rather than update them, thus preserving the integrity and accuracy of consumer data.
