CSI Cloud Migration & Multi-Cloud 2 — Questions and Answers
Question 1: A company wants to move its on-premises Oracle database to AWS with minimal code changes. Which migration strategy best fits this requirement?
- Replatform using AWS RDS for Oracle (Correct answer)
- Refactor to Aurora PostgreSQL
- Repurchase with a SaaS ERP
- Retire the database entirely
Correct answer: Replatform using AWS RDS for Oracle
Replatforming (lift-tinker-and-shift) to AWS RDS for Oracle preserves the Oracle engine while reducing operational overhead with minimal code changes.
Question 2: In a multi-cloud strategy, which tool is commonly used to manage infrastructure consistently across AWS, Azure, and GCP?
- AWS CloudFormation
- Terraform (Correct answer)
- Azure Resource Manager
- Google Deployment Manager
Correct answer: Terraform
Terraform is a cloud-agnostic IaC tool that supports AWS, Azure, GCP, and many other providers through provider plugins.
Question 3: Which cloud migration pattern involves decomposing a monolithic application into microservices during the migration process?
- Rehost
- Replatform
- Refactor/Re-architect (Correct answer)
- Retain
Correct answer: Refactor/Re-architect
Refactoring or re-architecting involves redesigning the application, often breaking a monolith into microservices to leverage cloud-native capabilities.
Question 4: A business requires that certain data never leave a specific geographic region due to data sovereignty laws. Which multi-cloud feature addresses this requirement?
- Content Delivery Network (CDN)
- Data residency controls (Correct answer)
- Auto-scaling groups
- Global load balancing
Correct answer: Data residency controls
Data residency controls allow organizations to pin data storage and processing to specific geographic regions, satisfying sovereignty requirements.
Question 5: What is the primary purpose of a cloud migration factory?
- To automate the creation of cloud provider accounts
- To standardize and accelerate migrations using repeatable patterns and tooling (Correct answer)
- To manufacture physical servers for hybrid cloud
- To generate cloud cost reports automatically
Correct answer: To standardize and accelerate migrations using repeatable patterns and tooling
A cloud migration factory uses standardized processes, automation, and tooling to industrialize and accelerate the migration of workloads at scale.
Question 6: During a cloud migration assessment, an application is flagged as having high technical debt and low business value. What is the recommended disposition?
- Rehost it as-is to reduce cost
- Refactor to modernize the codebase
- Retire the application (Correct answer)
- Repurchase with a cloud-native SaaS alternative
Correct answer: Retire the application
Applications with high technical debt and low business value are prime candidates for retirement, eliminating unnecessary cost and complexity.
Question 7: Which networking approach enables consistent connectivity between workloads distributed across multiple cloud providers?
- VPC peering within a single provider
- Software-defined WAN (SD-WAN) (Correct answer)
- Public internet routing only
- Direct Connect to a single cloud
Correct answer: Software-defined WAN (SD-WAN)
SD-WAN provides vendor-agnostic, policy-driven connectivity across multiple cloud environments and on-premises locations.
