CV0-004 Troubleshooting Practice Question
A company migrated to a hybrid cloud and users report slow access to files stored in the cloud. The on-premises network is 100 Mbps. What troubleshooting step should be taken?
⚠ Common exam trap
CV0-004 often tests the misconception that slow cloud file access is always due to cloud storage performance, leading candidates to choose increasing the performance tier instead of first diagnosing the network path.

Correct answer & explanation
✓
Check VPN bandwidth and latency
The most likely bottleneck in a hybrid cloud scenario where users access cloud-stored files over a 100 Mbps on-premises connection is the VPN tunnel used to connect to the cloud. VPN bandwidth and latency directly affect file access speed, and issues such as insufficient tunnel capacity, high latency, or packet loss can cause slow transfers. Checking these metrics is the logical first troubleshooting step to identify whether the network path is the limiting factor.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable compression on the cloud storage gateway
Why it's wrong here
Compression reduces payload size but cannot raise the 100 Mbps on-premises link's throughput, so the bottleneck persists. It is tempting because compression genuinely helps bandwidth-constrained WAN transfers, but it would be the answer where the link is adequate yet data volumes are large, not where raw capacity is the constraint.
- ✓
Check VPN bandwidth and latency
Why this is correct
Checking VPN bandwidth and latency directly addresses the hybrid cloud bottleneck: the 100 Mbps on-premises link and any tunnel overhead cap throughput for cloud file access. Measuring both reveals whether encryption, routing or congestion is throttling transfers, satisfying the stem's constraint of diagnosing slow cloud file access across the hybrid connection.
- ✗
Increase cloud storage performance tier
Why it's wrong here
The bottleneck is the 100 Mbps on-premises link, not the cloud storage tier, so raising that tier changes nothing about transfer speed. It tempts because storage tiers govern IOPS and throughput for workloads running inside the cloud, which would be the right fix if the slowness were server-side.
- ✗
Move files to on-premises storage
Why it's wrong here
Relocating files on-premises abandons the hybrid design rather than diagnosing the 100 Mbps link that actually throttles transfers. It tempts as a quick workaround when the cloud connection is genuinely inadequate, but the stem asks for a troubleshooting step, not an architectural reversal.
