Docker Certified Associate Certification Training Course - Application Containerization Benefits and Drawbacks

The video tutorial discusses the benefits and drawbacks of using containers compared to virtual machines. Containers offer a secure, lightweight, and cost-effective solution that is portable and reproducible across multiple cloud platforms. However, they face challenges such as lack of isolation, security vulnerabilities, and OS lock-in issues. Virtual machines, while more isolated, have limitations in hosting multiple applications.

What is one of the main advantages of containers over virtual machines?

• They are larger and more resource-intensive.

• They are less portable across cloud platforms.

• They boot slower than virtual machines.

• They are smaller and use fewer resources.

Which of the following is NOT a benefit of containers?

• They require more resources than virtual machines.

• They can run on multiple cloud platforms.

• They are lightweight and cost-effective.

• They are portable and reproducible.

How do containerized applications enhance deployment?

• By being incompatible with most systems.

• By requiring more manual configuration.

• By being less reproducible.

• By allowing multiple containers from a single image.

What is a significant drawback of containers?

• They provide complete isolation from the operating system.

• They are always protected by security scanners.

• They consume fewer resources than virtual machines.

• They have OS lock-in issues.

What problem can arise due to the lack of isolation in containers?

• They are completely isolated from the core operating system.

• They are always secure and monitored.

• They may not be protected by security tools.

• They have no compatibility issues.
