Latency, not bandwidth, is what makes overseas VDI sessions feel slow on Gigabit internet
Short answer
C VDI interactivity is bound by round-trip time, so lowering latency to the hosting region fixes overseas slowness that Gigabit bandwidth cannot.
Question
Key Takeaways
VDI interactivity is bound by round-trip latency, so a fat pipe that is far away feels worse than a thin pipe that is close.
Overseas VDI users complain of slowness even though their office has Gigabit internet. Interactive desktop sessions are sensitive to round-trip time, and a long physical path to the VDI host adds latency that bandwidth increases cannot remove, so lowering latency is the fix.
Common mistake: Increasing bandwidth (A) is the reflex for slow connections, but the scenario already states Gigabit capacity, and more bandwidth does nothing for the delay each keystroke must endure.
Expert Analysis
Why the Answer Is Correct
A VDI session ships keystrokes, mouse events, and screen deltas back and forth continuously, so the user experience tracks round-trip time more than throughput. An overseas path to the hosting region accumulates propagation and transit delay on every exchange, and no amount of idle bandwidth cancels that waiting time. Bringing the session closer or otherwise lowering latency directly shortens every interaction, which is what the users perceive as speed.
Why the Other Options Are Wrong
A, more bandwidth, addresses throughput, but the office already has Gigabit and the complaint pattern is interaction lag, not slow downloads. B, compression, shrinks payloads and helps marginal links, but with a Gigabit pipe the bottleneck is delay per exchange, not bytes on the wire. D, added redundancy, improves availability and failover, neither of which changes how long a single packet takes to cross the ocean.
Community Comment Notes
Joshuac1392 defines latency as the round-trip data travel time and notes that even gigabit capacity cannot fix significant delay in interactive sessions. BigM adds the key observations that VDI performance is highly latency-sensitive, affecting mouse movements and keystrokes, and that Gigabit already rules out bandwidth. The unanimous vote backs C.

Joshuac1392 👍 3 Answered CC. Lowering latency The most likely solution to address slowness issues for VDI (Virtual Desktop Infrastructure) users overseas, despite having Gigabit internet, is to lower latency. Latency refers to the time it takes for data to travel from the user's device to the server and back. Even with high bandwidth (Gigabit internet), if there is significant latency, users may experience delays in accessing and interacting with their virtual desktops.

BigM 👍 1 Answered CExplanation: Even though the remote office has Gigabit internet, users are still experiencing slowness in the VDI (Virtual Desktop Infrastructure) experience. This suggests that bandwidth is not the issue, but latency likely is. 🔹 VDI performance is highly sensitive to latency rather than raw bandwidth. 🔹 Latency affects real-time interactions, such as mouse movements and keystrokes. 🔹 Lowering latency improves responsiveness and user experience.
