Which two statements best describe elements of Continuous Delivery?

 Continuous Delivery is a set of practices that enable teams to release value to customers in short cycles, with high quality and low risk. One of the key practices of Continuous Delivery is to automate testing of Features and nonfunctional requirements, such as performance, security, and usability. This ensures that the code is always in a releasable state and reduces the feedback time and cost of defects. Another key practice of Continuous Delivery is to maintain a staging environment that emulates production, where the final integration, validation, and acceptance testing can take place before deployment. This reduces the risk of failures and errors in production and enables faster and more reliable releases. References: SAFe® for Teams - Know Your Role on an Agile Team, SAFe for Teams 6.0 (SP) Certification Training, SAFe for Teams | SAFe Practitioner (SP) Certification
