CV0-004 Practice Question: Which THREE are common causes of network latency…
Which THREE are common causes of network latency in a cloud environment? (Choose three.)
⚠ Common exam trap
The trap in the CompTIA Cloud+ exam is that candidates often confuse 'high bandwidth utilization' with 'network congestion,' but the exam tests that latency is caused by queuing delay from saturation, not utilization alone, and that DNS delays are a pre-connection issue, not a latency factor during data transfer.

Correct answer & explanation
✓
Firewall rule misconfiguration
Firewall rule misconfiguration (A) is a common cause of network latency in a cloud environment because overly restrictive or incorrectly ordered rules can force traffic to be inspected multiple times or dropped and retransmitted. For example, a misconfigured stateful firewall may require packets to traverse multiple security groups or network ACLs, adding processing delay per packet. This is especially impactful in virtualized environments where firewall processing is offloaded to the hypervisor or a virtual appliance, introducing micro-latency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Firewall rule misconfiguration
Why this is correct
Misconfigured firewall rules can cause dropped packets or added inspection delay.
- ✗
DNS resolution delays
Why it's wrong here
DNS delays impact initial connection setup, not ongoing data transfer latency.
- ✓
Jumbo frame misconfiguration
Why this is correct
Inconsistent MTU settings can cause fragmentation and increased latency.
- ✗
High bandwidth utilization
Why it's wrong here
High utilization alone does not necessarily cause latency unless congestion occurs.
- ✓
Packet loss
Why this is correct
Packet loss leads to TCP retransmission and increased latency.
