In the context of setting anomaly alert intensities in Prisma Cloud, an intensity setting of "Medium" could be used for the measurement of 100 events over 30 days. This setting indicates a moderate level of anomaly detection sensitivity, which is suitable for environments where there is a need to balance between detecting potential security issues and minimizing false positives.

To specifically target running containers with a Cloud Native Application Framework (CNAF) policy in Prisma Cloud, the administrator should scope the policy to Image names. By doing so, the policy will apply to containers based on the images they were created from, allowing for precise targeting of security policies to specific containers. This approach is part of Prisma Cloud's capabilities to provide granular security controls for containerized environments, ensuring that policies are effectively applied to the relevant containers​​.

In Prisma Cloud, the capability to scan serverless functions, such as AWS Lambda functions, for vulnerabilities is an integral part of ensuring cloud security posture management (CSPM) and compliance. Specifically, option C is correct because Prisma Cloud provides a dedicated section for defining policies related to serverless function vulnerabilities under the "Defend > Vulnerabilities > Functions" page. This feature allows administrators to create and manage policies that automatically scan serverless functions for known vulnerabilities, ensuring that the functions comply with the organization's security standards before they are deployed. This approach aligns with Prisma Cloud's comprehensive security model that covers various aspects of cloud security, including serverless functions, as outlined in the "Guide to Cloud Security Posture Management Tools" document​​
