Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
A company is planning a migration from on-premises to Google Cloud. They want to ensure minimal downtime and the ability to roll back quickly if issues arise. Which deployment strategy should they use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Phased migration
Phased migration involves moving workloads in stages, allowing testing and rollback at each phase. This minimizes risk and downtime. Blue/green and canary are more suited for application updates, not infrastructure migration. A big bang migration is high risk.
