Docker Certified Associate Certification Training Course - Validating Docker Image

The video tutorial discusses methods to validate Docker images, focusing on checksum verification and Docker Content Trust (DCDT). Checksum verification ensures the integrity of downloaded images, while DCDT uses digital signatures to verify image authenticity. The tutorial explains how to enable content trust by setting an environment variable, ensuring images are signed by publishers.

What are the two primary methods for validating a Docker image?

• Checksum verification and content trust

• Network security and firewall checks

• Image scanning and vulnerability assessment

• Code review and testing

What is the default method Docker uses to verify the integrity of downloaded images?

• Automated testing

• Manual inspection

• Checksum verification

• Content trust

How does Docker Content Trust ensure the integrity of Docker images?

• Using checksum verification

• By using digital signatures

• By scanning for vulnerabilities

• Through manual verification

What must be set to enable Docker Content Trust?

• Docker content trust value to zero

• Docker content trust value to one

• Docker security level to high

• Docker image verification to enabled

What is the role of digital signatures in Docker Content Trust?

• They verify the integrity and authenticity of images

• They compress the Docker images

• They encrypt the Docker images

• They provide a backup of the images
