NEW QUESTION # 184
Will a DTR security scan detect this?
Solution.private keys copied to the image
Answer: B
Explanation:
Explanation
= A DTR security scan will detect private keys copied to the image. DTR security scan is a feature of Docker Trusted Registry (DTR) that scans images to detect any security vulnerability1. DTR security scan uses the open source tool SecretScanner2 to find unprotected secrets in container images or file systems. SecretScanner can match the contents of images against a database of approximately 140 secret types, including private keys3. Therefore, if an image contains private keys, DTR security scan will report them as potential secrets and alert the user to remove them from the image. References:

NEW QUESTION # 187
Are these conditions sufficient for Kubernetes to dynamically provision a persistentVolume, assuming there are no limitations on the amount and type of available external storage?
Solution: A persistentVolumeClaim is created that specifies a pre-defined storageClass.
Answer: B
Explanation:
= The conditions are sufficient for Kubernetes to dynamically provision a persistentVolume, because a storageClass defines the provisioner and parameters for creating a volume on-demand. A persistentVolumeClaim that specifies a storageClass triggers the dynamic provisioning process, and Kubernetes will automatically create and bind a persistentVolume that matches the request. This eliminates the need for manual intervention by cluster administrators to provision storage volumes. References:
* Dynamic Volume Provisioning | Kubernetes
* Persistent volumes and dynamic provisioning | Google Kubernetes Engine ...
* Dynamic Provisioning and Storage Classes in Kubernetes
