CV0-004 Practice Question: Deploy a cloud application that requires…
A company wants to deploy a cloud application that requires predictable performance and dedicated resources for a critical database. Which cloud service model is MOST appropriate?
⚠ Common exam trap
A common mix-up: candidates choose PaaS (Option D) thinking it provides dedicated resources for databases (e.g., Azure SQL Database or Amazon RDS), but these services run on shared infrastructure with resource governance rather than true dedicated hardware, which can lead to performance variability under load.

Correct answer & explanation
✓
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) provides virtualized computing resources, such as dedicated virtual machines, storage, and networking, that can be configured to meet the predictable performance and dedicated resource requirements of a critical database. With IaaS, the company can provision a dedicated server instance with guaranteed CPU, memory, and I/O, avoiding the resource contention common in shared platforms. This model offers full control over the operating system, database software, and security settings, which is essential for a critical database workload.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Infrastructure as a Service (IaaS)
Why this is correct
IaaS allows provisioning of dedicated compute and storage for the database.
- ✗
Function as a Service (FaaS)
Why it's wrong here
FaaS is for stateless functions, not persistent database workloads.
- ✗
Software as a Service (SaaS)
Why it's wrong here
SaaS provides ready-to-use software, not dedicated database infrastructure.
- ✗
Platform as a Service (PaaS)
Why it's wrong here
PaaS typically manages the runtime, limiting control over dedicated resources.
