Docker DCA 認定試験の出題範囲:
| トピック | 出題範囲 |
|---|
| トピック 1 | - Domain 6: Storage and Volumes: This domain measures the practical storage configuration knowledge of DevOps engineers. It includes selecting appropriate storage drivers based on the OS, configuring devicemapper, and comparing object and block storage. Candidates must understand image layering and its implications on the file system, handle volume configuration for persistent storage, and perform system cleanup of unused images. Cross-node storage usage and differentiating roles between UCP workers and managers are also addressed, along with managing external certificates within UCP and DTR environments.
|
| トピック 2 | - Domain 5: Security: This part of the exam focuses on the knowledge of cloud infrastructure administrators and addresses Docker security configurations and practices. It covers image signing, security scans, Docker Content Trust, and default engine protections. Candidates must configure RBAC settings within UCP, integrate identity systems such as LDAP or Active Directory, and manage UCP client bundles. Understanding MTLS, swarm security defaults, and UCP
- DTR certificate usage is essential to meet the requirements of this domain.
|
| トピック 3 | - Orchestration: This section of the exam measures the skills of DevOps engineers and covers the configuration and management of Docker Swarm clusters. It includes tasks such as setting up manager and worker nodes, converting containers into services, and manipulating stacks. Candidates must understand the role of templates, inspect and troubleshoot running services, and adjust service scaling and placement using node labels. The section also requires interpreting docker inspect outputs and handling communication between Dockerized applications and legacy systems, emphasizing the importance of quorum in cluster resilience.
|
| トピック 4 | - Networking: This domain targets DevOps engineers and covers Docker networking fundamentals. It includes creating bridge and overlay networks, publishing ports, diagnosing connectivity issues, and understanding network driver types. Candidates are expected to comprehend the Container Network Model, configure external DNS, and apply HTTP
- HTTPS load balancing techniques using Docker EE. Additional topics include evaluating traffic flow between Docker components and distinguishing between different port publishing modes like host and ingress.
