Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 96

Which three options are reasons for an interface to go into err-disable state? (Choose three.)

Answer options

• A. security violation
• B. BPDU guard violation
• C. hard-coded speed duplex match on both sides
• D. ARP inspection
• E. storm-control broadcast
• F. grouping ports into a port channel

Correct answer: A, B, D

Explanation

The correct answers, A, B, and D, represent conditions that can trigger an interface to go into err-disable state due to security and configuration issues. Options C, E, and F are not valid reasons for this state as they pertain to configuration settings or traffic management that do not directly cause an interface to be err-disabled.
