I passed the Docker Certified Associate Exam, thanks to the Pass4Success practice questions. There was a question about installing Docker on different operating systems. It asked for the steps to install Docker on a Windows machine using Docker Desktop. I was a bit unsure about the exact steps but still succeeded.

Happy to share that I passed the Docker Certified Associate Exam. The practice questions from Pass4Success were a lifesaver. One challenging question was about persistent storage in Docker. It asked how to create and manage named volumes and bind mounts. I had to think hard about the differences but managed to get it right.

Just cleared the Docker Certified Associate Exam! The Pass4Success practice questions were a great resource. There was a tricky question on creating Docker images using multi-stage builds. It asked how to minimize the final image size by using multiple FROM statements. I wasn't entirely confident in my answer, but I still made it through.

I recently passed the Docker Certified Associate Exam, and I must say, the Pass4Success practice questions were incredibly helpful. One of the questions that stumped me was about setting up a multi-node Docker Swarm cluster. It asked about the specific commands needed to initialize the swarm and add worker nodes. I was unsure about the exact sequence, but I managed to pass the exam.

Passing the Docker Certified Associate Exam was a great achievement for me, and I owe a big part of my success to the practice questions from Pass4Success. One question that I remember from the exam was related to running containerized applications from pre-existing images stored in a centralized registry. It required me to demonstrate my understanding of how to efficiently manage and deploy containers in a distributed environment, which was a key concept covered in my preparation.

Free Docker Docker Certified Associate Exam Exam Actual Questions

Question #4

Is this a way to configure the Docker engine to use a registry without a trusted TLS certificate?

Solution: Set IGNORE_TLS in the 'daemon.json' configuration file.

Reveal Solution Hide Solution
Question #5

You are pulling images from a Docker Trusted Registry installation

configured to use self-signed certificates, and this error appears:

`x509: certificate signed by unknown authority.

You already downloaded the Docker Trusted Registry certificate authority

certificate from https://dtr.example.com/ca.

How do you trust it? (Select two.)

Reveal Solution Hide Solution
Correct Answer: C, E

To trust a self-signed certificate from a Docker Trusted Registry (DTR), you need to place the certificate in the appropriate location on all cluster nodes and restart the Docker daemon. There are two possible locations for the certificate, depending on your OS and Docker version1:

* /etc/docker/certs.d/dtr.example.com/ca.crt: This is the preferred location for Linux systems and Docker versions 1.13 and higher. This directory is scanned by Docker for certificates and keys for each registry domain2.

* Your OS certificate path: This is the fallback location for other OSes and Docker versions. You need to find the certificate store for your OS and copy the certificate there. You also need to trust the certificate system-wide, which may require additional steps depending on your OS3.

The other options are not correct because:

* Passing '-trust-certificate ca.crt to the Docker client is not a valid option. There is no such flag for the Docker client4.

* Placing the certificate in '/etc/docker/dtr/dtr.example.com.crt' is not a valid location. The certificate should be in the /etc/docker/certs.d directory, not the /etc/docker/dtr directory1.

* Passing -- insecure-registry to the Docker client is not a recommended option. This flag disables the TLS verification for the registry, which makes the communication insecure and vulnerable to attacks.
