1Z0-1123-25 Question 10
Single answerAn organization is migrating its on-premises e-commerce platform to Oracle Cloud Infrastructure (OCI). The team has completed an initial discovery phase, identifying application dependencies and security requirements. Which next step best aligns with fundamental best practices for ensuring a smooth migration process?
- A
Immediately replicate all on-premises data and cut over all production workloads at once
- B
Conduct a pilot migration with a representative subset of the application
- C
Skip environment testing to speed up the overall migration timeline
- D
Ignore non-critical security concerns to focus on core functionality first
Show answer and explanation
Correct answer: B
Explanation
A pilot migration is one of the most important fundamentals in any cloud migration strategy, especially on Oracle Cloud Infrastructure. By migrating a representative subset of the application first, teams can validate network configurations, security policies, data replication approaches, and performance expectations in a controlled environment. This approach mitigates risk, provides valuable insights for the broader migration, and aligns with Oracle� recommended best practices as outlined in the Oracle Cloud Infrastructure documentation on migration planning.
- A. Incorrect.
Option 1 is incorrect because a full cutover without a phased approach or pilot can lead to unexpected downtime and complexities that haven't been tested. Best practices recommend phased migrations after careful planning and testing.
- B. Correct.
Option 2 is correct because performing a pilot migration with a representative subset allows you to test application behavior, performance, and security in OCI before committing the entire workload. This ensures a smoother transition and reduces risk.
- C. Incorrect.
Option 3 is incorrect because skipping environment testing deprives the organization of crucial validation steps that ensure workloads function correctly in OCI. Testing is vital to verify performance, security, and reliability.
- D. Incorrect.
Option 4 is incorrect because ignoring security, even if it's considered non-critical, can introduce vulnerabilities. Security should always be an integral part of the migration process, regardless of the perceived priority of each concern.
