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
✓
Violation of electronic security perimeter (ESP) requirements
NERC CIP requires clear electronic security perimeters (ESPs) between OT and other networks. Connecting OT to the corporate network can compromise the ESP, allowing unauthorized access to critical assets. This is a key compliance requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Violation of electronic security perimeter (ESP) requirements
Why this is correct
NERC CIP mandates ESPs to protect critical cyber assets; any connection must be controlled and monitored.
- ✗
Latency issues affecting real-time control
Why it's wrong here
Latency is a reliability issue but not the primary compliance risk.
- ✗
Increased bandwidth costs for WAN connectivity
Why it's wrong here
Cost is an operational concern, not a compliance risk.
- ✗
Incompatibility with legacy serial protocols
Why it's wrong here
Technical incompatibility is a challenge but not the most significant compliance risk.
