Premium questions with real-world problems

The Docker online test evaluates a candidate’s ability to work with the platform virtualization tool Docker, including the knowledge of how to configure containers and images, run services within those containers, and manage the lifecycle of those containers.

It’s an ideal test for pre-employment screening of candidates applying for any developer role. A good candidate for any job requiring the use of virtualization will be able to display competency with using Docker, one of the most popular containerization and virtualization platforms. This Docker test can be used to screen large groups of candidates to select only those with the required Docker knowledge to bring in for an interview.

Docker Command Line Arguments Docker Compose New Public

The automation team is testing their background Docker web server containers. They need to cleanly remove the existing containers without leaving any artifacts behind, then start new containers.

Complete the following docker commands to achieve these objectives:

# Gracefully end all processes in the containers
host> docker-compose stop
# Remove the containers and their anonymous volumes
host> docker-compose ____ -v
# Start containers in background
host> docker-compose up ____ apache php mysql

Docker Command Line Arguments Life Cycle New Public

As part of a load balancing scheme, your company uses multiple virtual machines which can provision and deprovision Docker containers as demand changes.

Complete the docker commands (with no additional arguments) that manage the lifecycle of a docker image.

  1. When a virtual machine completes startup, it runs the following command to ready the custom container image:
    docker create --name balanced-container company-image
  2. When the load balancer detects high usage, it signals the virtual machine to make the container available for use. The VM runs the following command:
    docker ____ balanced-container
  3. The load balancer detects that a container has been underutilized for more than 15 minutes. It signals the VM to suspend the container to conserve CPU resources. The VM runs the command:
    docker ____ balanced-container
  4. Finding an increased load again, the load balancer signals the VM to awaken the container. The VM runs the command:
    docker ____ balanced-container
  5. After an hour of underutilization, the load balancer signals the VM to gracefully end all processes in the container to conserve RAM resources. The VM runs the command:
    docker ____ balanced-container

Pass/fail grouping

Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.

Full customization

We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.

Cheating protection

Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.

Candidate reporting

Get an overview into the percentage of passes and fails. Then dive deeper into the results of your top candidates to select who goes onto the next phase of hiring.
