What are two purposes of a community of practice?

Communities of Practice (CoPs) within the SAFe framework are designed to be organized groups with a common interest in a specific technical or business domain. They collaborate regularly to share information, improve their skills, and actively work on advancing their knowledge of the domain. The purposes of CoPs include fostering a culture built on professional networking, personal relationships, shared knowledge, and common skills. This aligns with the options D and E, as CoPs enable SAFe participants to exchange knowledge and skills with people across the entire organization and provide opportunities for networking1. CoPs are not primarily for approving standards or aligning tasks across teams, nor are they for refining definitions of done, which excludes options A, B, and C from being correct answers.
