Question 38
Which PoE mode enables powered-device detection and guarantees power when the device is 
detected? 
A. dynamic 
B. static 

---

C. active 
D. auto 
Answer:
B 
Explanation
static—Enables powered-device detection. Pre-allocate (reserve) power for a port before the 
switch discovers the powered device. The switch reserves power for this port even when no 
device is connected and guarantees that power will be provided upon device detection.

Note: “auto” – Enables powered-device detection; if enough power is available, automatically 
allocates power to the PoE port after device detection (default setting).” The answer “auto” is not 
correct as “auto” only allocates power “if enough power is available”.
