- A
Refactor the application into microservices and use Kubernetes.
Why wrong: Refactoring into microservices is a major architectural change, not minimal changes.
- B
Increase the size of the virtual machines and allocate more vCPUs.
Scaling up provides more CPU and memory, which can improve performance for resource-intensive applications without requiring architectural changes.
- C
Move the application to a containerized environment using Docker.
Why wrong: Containerization would require significant rework and might not be considered 'minimal changes'.
- D
Implement a content delivery network (CDN) to cache static assets.
Why wrong: CDNs help with static content but do not address the overall performance of a legacy monolithic application that likely has dynamic content.
CV0-004 Deployment Practice Question
This CV0-004 practice question tests your understanding of deployment. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
An organization is migrating a legacy monolithic application to the cloud using a re-platform approach (lift and shift with minimal changes). After migration, performance is worse than on-premises. Which of the following is the BEST next step to improve performance without significant application changes?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
Increase the size of the virtual machines and allocate more vCPUs.
In a re-platform (lift and shift) migration, the application's architecture remains unchanged, so performance issues often stem from insufficient cloud resources. Increasing the VM size and allocating more vCPUs directly addresses resource contention without requiring code modifications, making it the best immediate step.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Refactor the application into microservices and use Kubernetes.
Why it's wrong here

Why this is correct
Scaling up provides more CPU and memory, which can improve performance for resource-intensive applications without requiring architectural changes.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the misconception that cloud-native solutions like containers or microservices are always the answer, but the trap here is that the question explicitly limits changes, making vertical scaling the only viable option without re-architecting.
Detailed technical explanation
How to think about this question
Under the hood, increasing vCPUs and memory reduces CPU queue length and memory pressure, directly improving throughput for compute-bound or memory-bound monolithic workloads. Cloud providers like AWS offer burstable instances (e.g., T3) that can provide additional performance credits, but for sustained loads, larger instance types (e.g., M5, C5) with dedicated vCPUs are more reliable. Real-world scenarios often involve right-sizing after migration using tools like AWS Compute Optimizer or Azure Advisor.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
