220-1102 Practice Question: That their cloud-based virtual desktop (VDI) is…
A user reports that their cloud-based virtual desktop (VDI) is disconnecting frequently. The user's internet connection is stable, and other cloud services work fine. The technician checks the VDI's resource usage and finds that the virtual machine's RAM is consistently at 95% usage. What should the technician do to resolve the disconnections?
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 amount of RAM allocated to the VDI.
This scenario tests advanced troubleshooting of VDI performance. High memory usage can cause the VM to become unresponsive, leading to disconnections. Increasing the VM's RAM allocation directly addresses the resource bottleneck. Reducing RAM would worsen the problem, and network or GPU issues are not indicated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduce the amount of RAM allocated to the VDI.
Why it's wrong here
Reducing the amount of RAM allocated to a VDI would exacerbate performance issues, not resolve them. Insufficient memory forces the virtual machine's operating system to heavily rely on its paging file (swap space) on disk, leading to excessive disk I/O. This "memory pressure" significantly degrades system responsiveness, causing applications to freeze, the desktop to become unresponsive, and ultimately resulting in disconnections from the cloud-based VDI session.
- ✓
Increase the amount of RAM allocated to the VDI.
Why this is correct
Increasing the amount of RAM allocated to the VDI directly addresses memory-related performance bottlenecks. Providing more physical memory to the virtual machine allows the operating system and applications to run more efficiently, reducing the need for disk-based paging. This improves overall system responsiveness, prevents applications from crashing or becoming unresponsive due to memory exhaustion, and significantly enhances session stability, thereby mitigating disconnections.
- ✗
Reinstall the VDI client software on the user's device.
Why it's wrong here
Reinstalling the VDI client software on the user's local device is an inappropriate troubleshooting step for disconnections stemming from a cloud-based VDI's performance. The client software primarily facilitates the connection and displays the remote desktop; it does not influence the virtual machine's internal resource allocation or performance on the server side. Issues like insufficient RAM within the VDI itself cannot be resolved by manipulating the local client application.
- ✗
Enable GPU acceleration for the VDI.
Why it's wrong here
Enabling GPU acceleration for the VDI would not resolve disconnections caused by general system unresponsiveness or memory issues. GPU acceleration is specifically designed to offload graphics processing tasks from the CPU, improving visual performance for applications with demanding graphical interfaces or video playback. It has no direct impact on the amount of available system RAM or the underlying memory pressure that leads to overall VDI instability and disconnections.
