FC0-U71 A small business wants to use a CRM system Practice Question
A small business wants to use a CRM system. They need to access it from mobile devices and desktops without installing software. Which deployment model fits?
⚠ Common exam trap
Candidates often confuse PaaS with SaaS, thinking a platform is sufficient for a ready-to-use application, but PaaS requires development effort to create the CRM software, whereas SaaS delivers it as a finished service.
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
✓
Software as a Service (SaaS)
Software as a Service (SaaS) delivers the CRM application over the internet, allowing users to access it from any device with a web browser without installing software. This model matches the requirement for mobile and desktop access with zero local installation, as the provider hosts and manages the entire application stack.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Platform as a Service (PaaS)
Why it's wrong here
PaaS provides a managed environment for developing and deploying applications, but the CRM itself must still be built or installed and maintained on that platform. It would be correct for hosting custom application code, not for consuming a finished CRM through browsers and mobile devices without installation.
- ✓
Software as a Service (SaaS)
Why this is correct
SaaS delivers the CRM over the internet via a browser, so no local installation is needed on mobiles or desktops. This directly satisfies the stem's requirement for software-free access across both device types, with the provider handling hosting, patching and availability.
- ✗
On-premises
Why it's wrong here
On-premises deployment requires installing and maintaining the CRM on the business's own servers, so mobile and desktop access depends on local software and network configuration rather than a browser. It would be correct where data residency or full infrastructure control is mandated, not for software-free access from any device.
- ✗
Infrastructure as a Service (IaaS)
Why it's wrong here
IaaS supplies raw virtual machines, storage and networking, leaving the CRM application, middleware and updates for the business to install and manage, so nothing is accessible without software deployment. It would be correct when full control of the operating system and infrastructure configuration is required, not for browser and mobile access to a ready CRM.
