Question 7 of 10
Which of the following methods can be used to ensure port security by completely disabling access to a network?

answer

Physically removing the patch cable from the switch port


Using a captive portal


Implementing IEEE 802.1X Port-based Network Access Control


MAC filtering

Answer 1

Correct answers:
- Physically removing the patch cable from the switch port
- Implementing IEEE 802.1X Port‑based Network Access Control

Why: unplugging the port obviously prevents any access, and 802.1X keeps a switch port in a blocked state until proper authentication, effectively disabling access for unauthenticated devices. MAC filtering can block devices but is easily spoofed (not a complete lock-down). A captive portal still allows basic network connectivity until web authentication and does not fully disable access.
