QUESTION 30
Which option lists the modes that are available for configuring UDLD on a Cisco switch?
A. normal and aggressive
B. active and aggressive
C. normal and active
D. normal and passive
E. normal and standby
Correct Answer: A
Explanation:
The Cisco-proprietary UDLD protocol monitors the physical configuration of the links between devices and ports that support UDLD. UDLD detects the existence of unidirectional links. When a unidirectional link is detected, UDLD puts the affected port into the errdisabled state and alerts the user. UDLD can operate in either normal or aggressive mode
