The answer is Virtual Desktop Infrastructure (VDI). VDI is the correct choice because it hosts entire desktop environments on a central server, delivering only screen updates to the user’s device via a remote display protocol. This means employees can access internal applications from home without installing software on their personal devices, as all processing and data remain securely on the server. On the CompTIA ITF+ FC0-U61 exam, this concept tests your understanding of virtualization and remote access methods, often appearing in questions contrasting VDI with VPNs or remote desktop services—a common trap is assuming a VPN alone avoids software installation, but VPNs still require a client. Remember the memory tip: “VDI streams the screen, not the software.”
FC0-U61 IT Concepts and Terminology Practice Question
This FC0-U61 practice question tests your understanding of it concepts and terminology. 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.
A company wants to implement a solution that allows employees to access internal applications from home without installing software on their personal devices. Which technology should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Virtual Desktop Infrastructure (VDI)
VDI provides hosted virtual desktops that users can access from any device, including personal ones, without installing software locally. The applications run on the server, and only screen updates are sent to the client, meeting the requirement of no software installation on personal devices.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Remote Desktop Services (RDS)
Why it's wrong here
RDS requires a Remote Desktop client installed on the device.
✗
Thin client
Why it's wrong here
Thin client is a hardware device, not a solution for existing personal devices.
✗
Virtual Private Network (VPN)
Why it's wrong here
VPN provides secure network access but still requires software on the client.
✓
Virtual Desktop Infrastructure (VDI)
Why this is correct
VDI provides a full desktop experience accessible via a web browser without installing software.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing VPN with VDI: candidates often think a VPN alone provides application access, but VPN only grants network-level connectivity and still requires local software or RDP clients to run the actual applications.
Detailed technical explanation
How to think about this question
VDI uses a hypervisor to host multiple virtual machines, each running a full desktop OS, and delivers the user interface via protocols like PCoIP or HDX. The key distinction from RDS is that VDI provides a dedicated desktop environment per user, whereas RDS shares a single OS instance. In practice, VDI can be accessed via a web browser using HTML5 clients, eliminating the need for any local software, which is critical for BYOD scenarios.

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 FC0-U61 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.
