PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
A project manager is planning to migrate an on-premises data center to a hybrid cloud environment. The organization requires that the project team can provision and manage both on-premises and cloud resources through a single pane of glass. Which technology should the project manager prioritize?
⚠ Common exam trap
The trap here is assuming that any cloud service model (IaaS, PaaS, SaaS) inherently provides unified management across hybrid environments, when in fact a dedicated management platform is required.

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
✓
Hybrid cloud management platform
A hybrid cloud management platform provides a single interface to manage both on-premises and cloud resources, meeting the requirement for unified provisioning and monitoring. The other cloud service models (IaaS, PaaS, SaaS) each address specific layers but do not offer cross-environment management, so they fail to satisfy the single-pane-of-glass need.
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 it's wrong here
IaaS provides virtualized computing resources over the internet, but it does not natively unify on-premises management. The project team would still need separate tools for on-premises infrastructure, failing the single-pane-of-glass requirement. IaaS is a cloud service model, not a management platform that spans both environments.
- ✗
Software as a Service (SaaS)
Why it's wrong here
SaaS delivers applications over the internet, but it does not manage underlying infrastructure. The project needs to manage servers and networks in both on-premises and cloud locations; SaaS abstracts those layers away. Thus, SaaS cannot provide the required unified infrastructure management.
- ✓
Hybrid cloud management platform
Why this is correct
A hybrid cloud management platform is designed to provide a unified interface for managing resources across on-premises and cloud environments. It enables centralized provisioning, monitoring, and governance, directly satisfying the requirement for a single pane of glass and simplifying operations for the project team.
- ✗
Platform as a Service (PaaS)
Why it's wrong here
PaaS offers a development and deployment environment, but it does not manage on-premises infrastructure. The project requires unified control over both on-premises and cloud resources, which PaaS does not deliver. PaaS focuses on application hosting, not cross-environment infrastructure orchestration.
Quick reference
Cloud Service Model Comparison
| Model | You Manage | Provider Manages | Examples |
|---|---|---|---|
| IaaS | OS, runtime, apps, data | Hardware, hypervisor, networking | EC2, Azure VMs, GCP Compute Engine |
| PaaS | Apps and data | OS, runtime, middleware, hardware | Elastic Beanstalk, Azure App Service |
| SaaS | Data and settings only | Everything else | Microsoft 365, Salesforce, Workday |
| FaaS / Serverless | Function code only | Infra, scaling, runtime | Lambda, Azure Functions, Cloud Run |
| CaaS | Containers and apps | Kubernetes, OS, hardware | EKS, AKS, GKE |
