1Z0-1123-25 Question 99
Select 2You are an OCI migration architect planning to move your containerized e-commerce platform from an on-premises environment to Oracle Cloud Infrastructure (OCI). During the Discovery and Assessment phase, which two tasks must you complete to ensure a smooth transition? (Choose two)
- A
Inventory and categorize existing container images, their versions, and dependencies.
- B
Immediately deploy an Oracle Container Engine for Kubernetes (OKE) cluster on OCI.
- C
Evaluate network connectivity, security requirements, and compliance constraints for containerized workloads.
- D
Execute container resizing and cost-optimization strategies in the production environment.
- E
Rebuild all Docker images using an OCI-specific base image to ensure portability.
Show answer and explanation
Correct answers: A, C
Explanation
In the Discovery and Assessment phase of migrating containerized workloads to OCI, gathering details on existing container images, dependencies, and environment requirements (network, security, compliance) is crucial. This foundational information helps guide subsequent phases such as planning, building an appropriate OCI architecture, and ensuring a smoother deployment. Refer to Oracle� official documentation for 'Migrating Containerized Applications to OCI' to learn more about each phase and the recommended best practices for container migrations.
- A. Correct.
Option 1 is correct. Before migrating containers, you need to inventory and categorize container images, versions, and dependencies to identify compatibility or upgrade considerations. This baseline ensures you understand all components and can plan the migration strategy accordingly.
- B. Incorrect.
Option 2 is incorrect. Immediately deploying an OKE cluster is typically done in a later phase (Planning and Implementation). The Discovery and Assessment phase focuses on gathering information and requirements, not immediately provisioning resources.
- C. Correct.
Option 3 is correct. Evaluating network connectivity and security requirements is a critical part of the early Discovery phase. This step clarifies compliance requirements and network architecture constraints before deployment on OCI.
- D. Incorrect.
Option 4 is incorrect. Executing container resizing or cost-optimization strategies typically occurs after initial assessments and architecture planning. Over-optimizing early can lead to overlooking practical constraints discovered during assessment.
- E. Incorrect.
Option 5 is incorrect. Rebuilding Docker images for OCI-specific base images may be necessary later if compatibility issues arise. However, this is not part of the initial Discovery and Assessment phase, which focuses on gathering requirements and analyzing existing workloads.
