Answer:
Agent Armstrong needs to be licensed and appointed in every state in which beneficiaries to whom he markets ABC MA plans are located.
Explanation:
In the given scenario XYZ Agency maintains a website marketing the MA plans with which it has contracts. So they are not in one location.
Clients from multiple states can subscribe to their services via website.
Agent Armstrong follows up with individuals who request more information about ABC MA plans via the website and tries to persuade them to enroll in ABC plans.
Since clients enroll in different locations there is a need for Armstrong to be licensed and appointed in every state in which beneficiaries to whom he markets ABC MA plans are located.
This will satisfy the varying compliance rules that each state of operation may have. Thereby providing seamless service delivery to customers of XYZ agency.
