FC0-U71 Practice Question: That the company's customer relationship…
A user reports that the company's customer relationship management (CRM) application is slow after a recent network upgrade. What could be the cause?
⚠ Common exam trap
CompTIA often tests the misconception that slowness after a network change must be caused by bandwidth or user load, rather than a firewall or ACL misconfiguration that introduces latency or packet loss.

Correct answer & explanation
✓
The network firewall is blocking certain CRM traffic.
A network firewall can introduce latency or block traffic if its rules are misconfigured after an upgrade. If the CRM application relies on specific ports or protocols (e.g., HTTPS on TCP 443, or a proprietary port like TCP 8080), the firewall might be inspecting, throttling, or dropping packets, causing perceived slowness. This is a common post-upgrade issue when ACLs or stateful inspection rules change.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The network firewall is blocking certain CRM traffic.
Why this is correct
Firewall rules may inadvertently throttle or block necessary ports, causing slowdown.
- ✗
The application has too many users.
Why it's wrong here
More users might slow the app, but the question says after a network upgrade, not user increase.
- ✗
The user's password has expired.
Why it's wrong here
Password expiration affects login, not application performance.
- ✗
The user is entering data too quickly.
Why it's wrong here
Data entry speed does not affect application responsiveness.
