Final answer:
For PCI DSS scoping, it's crucial to identify system components in the cardholder data environment, including those storing, processing, or transmitting cardholder data, and any that may impact security.
Step-by-step explanation:
When scoping an environment for PCI DSS, it is important to identify all system components that are part of or connected to the cardholder data environment (CDE). The PCI DSS scope includes any system that stores, processes, or transmits cardholder data, as well as any system that can affect the security of the CDE. To properly scope the environment, organizations need to create an accurate network diagram that includes all connections to the CDE, carry out an inventory of system components within the scope, and regularly review and update the scope to ensure that it remains accurate and covers all relevant components.
