Customs and Border Protection Border Patrol Agent (CBP BPA) Practice Exam

The correct choice is commonly used because it pertains directly to the verification of identity information for Lawful Permanent Residents (LPRs). CIS (USCIS Immigration Services) and CLAIMS (Client and Activity Tracking System) specifically manage immigration records, including statuses and histories for individuals who have obtained lawful permanent residency in the United States. This system allows for the efficient verification of a person's immigration status and identity, making it crucial for processes that require confirmation of legal residency.

The other systems listed serve different purposes: SEVIS is primarily used for monitoring international students and exchange visitors; NCIC (National Crime Information Center) focuses on criminal history and law enforcement information; and PCQS (Passenger Compliance Query System) is designed for customs enforcement regarding travelers. Therefore, while those systems are essential in their respective domains, they do not specifically cater to the identity verification needs of LPRs, making the chosen option the most relevant in this context.
