The data architect should recommend building a batch job to move two-year-old records off

platform, and delete records from Salesforce as an archiving solution. A batch job is a process that

runs in the background and performs operations on large volumes of data in Salesforce. By building a

batch job that moves two-year-old records off platform to an external storage system, such as

Amazon S3 or Google Cloud Storage, and deletes them from Salesforce, the data architect can reduce

the storage consumption and improve the performance of Salesforce org. Option A is incorrect

because using a third-party backup solution to backup all data off platform will not free up any

storage space in Salesforce, unless the data is also deleted from Salesforce after backup. Option B is

incorrect because building a batch job to move all records off platform, and delete all records from

Salesforce will result in losing all the current data in Salesforce, which may not be desirable or

feasible. Option D is incorrect because building a batch job to move all restore off platform, and

delete old records from Salesforce does not make sense, as restore implies restoring data back to

Salesforce, not moving it off platform.
