Customer Community Plus and Education Data Architecture (EDA) are two options that are required to use Advisor Link. Customer Community Plus is a license type that enables users to access Advisor Link features such as early alerts, appointments, and program plans from a portal. EDA is a data model that provides the foundation for Advisor Link and other education solutions. Person Accounts and Lightning Scheduler are not required to use Advisor Link. Reference:

Explanation
Data skew is the likely cause for all of these issues, such as record locking, long search times, and long record save times. Data skew is a condition that occurs when a large number of child records are associated with a single parent record, or when a large number of records are owned by a single user. Data skew can affect performance and functionality, such as locking records, slowing down queries, and increasing save times.
TDTM, insufficient code coverage, and insufficient data storage are not likely causes for all of these issues.

Explanation
A one-way integration between Salesforce and Marketing Cloud and a two-way integration between the event system and Salesforce are two integration directions that the consultant should recommend to meet the requirement. A one-way integration between Salesforce and Marketing Cloud allows Career Services to use student data in Salesforce to segment and target prospects for email campaigns in Marketing Cloud. A two-way integration between the event system and Salesforce allows Career Services to sync event attendance data from the event system to Salesforce, and update student records in Salesforce with career interest and credit completion data. A one-way integration between Marketing Cloud and the event system, and a two-way integration between the event system and Marketing Cloud are not integration directions that can meet the requirement.

The consultant should verify that trigger handlers were loaded into production when troubleshooting the issue of only the contact record being created when a contact record is created and a Community user is supposed to be created leveraging Table-Driven Trigger Management (TDTM) for the school that is implementing Salesforce with EDA to track parents and students in a community. Trigger handlers are classes that contain the logic for EDA triggers and can be controlled by Trigger Handler records. Trigger handlers need to be loaded into production before deploying declarative customizations or enabling features that depend on them. The consultant should verify that trigger handlers were loaded into production by checking if the EDA_TDTM package was installed or if the Trigger Handler records were created. The community being set to Active or declarative automations being deployed successfully are not steps that the consultant should verify when troubleshooting the issue of only the contact record being created when a contact record is created and a Community user is supposed to be created leveraging TDTM for the school that is implementing Salesforce with EDA to track parents and students in a community.

Explanation
Einstein Prediction Builder is a Salesforce solution that the consultant can recommend to automatically create a supporters' score based on their donation amount, giving capacity, giving history, and relationship type to the university. Einstein Prediction Builder allows the consultant to create custom predictive models without code, using fields from any object as inputs and outputs. Tableau CRM, Nonprofit Success Pack, and Insights Platform Data Integrity are not Salesforce solutions that can create a supporters' score based on the given criteria. References:
