A telecommunications company is implementing Service Cloud and Experience Cloud with a goal to have a single view of their customers.

Which two activities and tools should a Solution Architect recommend to address these concerns when planning the data migration activity and assure it is completed in a timely manner? Choose 2 answers
A . Q Duplicate Management in Salesforce can be used to identify and manage duplicate records.
B . Use an ETL tool with a staging database in order to run data cleansing tools to obtain a clean data set.
C . Iteratively test smaller loads against a developer or partial copy sandbox and the full load against a full copy sandbox.
D . Iteratively test smaller loads against a developer sandbox and the full load against a partial copy sandbox.

Answer: B,C

Explanation:

B. An ETL (Extract, Transform, Load) tool is a software that can help extract data from multiple sources, transform it according to business rules, and load it into a target destination, such as Salesforce. An ETL tool can also help run data cleansing tools, such as deduplication, validation, standardization, and enrichment, to obtain a clean data set before migrating it to Salesforce.

C. Iteratively testing smaller loads against a developer or partial copy sandbox and the full load against a full copy sandbox can help ensure the data migration is successful and error-free. A developer or partial copy sandbox can be used for testing the data quality, mapping, and transformation rules, while a full copy sandbox can be used for testing the performance, scalability, and integrity of the data migration.
