Which of the following is the most deterministic strategy you can use to push a
specific AP to join a specific controller?
- A.Select the least-loaded controller
- B.Use DHCP option 43
- C.Configure the master controller
- D.Configure the primary controller
- Answer & Explanation
- Report
Answer : [D]
Explanation :
Explanation :
| If the primary controller responds to an AP’s discovery methods, the AP will always try to join it first, ahead of any other controller. Configuring an AP with a primary controller is the most specific method because it points the AP to a predetermined controller. Other methods are possible, but they can yield ambiguous results that could send an AP to one of several possible controllers. |
