Quick Answer
The answer is Replatform and Replace. These two cloud-native migration strategies are correct because they both allow the company to leverage cloud-native features while minimizing code changes. Replatform involves moving a legacy application to a cloud-managed platform, such as switching from a self-hosted database to Amazon RDS, which requires only minor configuration adjustments rather than rewriting code. Replace goes further by adopting a SaaS alternative, like swapping a custom CRM for Salesforce, which eliminates code changes entirely while still delivering cloud-native capabilities. On the CompTIA Cloud+ CV0-004 exam, this question tests your understanding of the 7 Rs migration framework, specifically distinguishing between strategies that prioritize minimal code alteration versus full rearchitecture. A common trap is confusing Replatform with Refactor, which demands significant code rewrites. Remember the memory tip: “Replatform tweaks the platform, Replace swaps the app”—both keep your code intact.
This CV0-004 practice question tests your understanding of deployment. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is planning to migrate a legacy application to the cloud. They want to leverage cloud-native features while minimizing code changes. Which TWO migration strategies should they consider?
Replatform
Replatform offers cloud-native benefits with minimal changes.
Rehost
Why wrong: Rehost does not leverage cloud-native features.
Rebuild
Why wrong: Rebuild involves complete re-architecture.
Replace
Replace uses a cloud-native product with no code changes.
Refactor
Why wrong: Refactor requires significant code changes.

Correct answer & explanation
Replatform
Replatform (A) is correct because it involves migrating the application to a cloud-managed platform (e.g., moving from a self-managed database to Amazon RDS or Azure SQL Database) with minimal code changes, allowing the company to leverage cloud-native features like automated backups and scaling. Replace (D) is correct because it means adopting a SaaS alternative (e.g., replacing a custom CRM with Salesforce) that provides cloud-native capabilities without modifying existing code, aligning with the goal of minimizing code changes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
CompTIA often tests the distinction between 'Replatform' and 'Refactor,' where candidates mistakenly choose Refactor thinking it allows minimal changes, but Refactor actually requires significant code rework to adopt cloud-native patterns like containerization or serverless.
Detailed technical explanation
Replatforming often involves switching to a managed database service like Amazon RDS, which handles patching and replication via the MySQL or PostgreSQL wire protocol, requiring only a connection string change. Replace strategies leverage SaaS APIs (e.g., RESTful endpoints) that abstract underlying infrastructure, but may require data migration and integration testing to ensure compatibility with existing workflows. A subtle behavior is that replatforming can introduce latency if the cloud service is in a different region, requiring careful selection of availability zones.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
