A company must deploy APs at multiple branch sites, as well as at a main site, and selects HP
MSM APs for this purpose. A centralized HP MSM Controller must manage the APs. The exhibit
shows the VLANs and addressing for a few of the branches as examples.
What is a guideline for deploying the APs and ensuring that they can contact the controller?

A.
The company should only use the DHCP option for discovery if the network DHCP server does
not already use option 43 to configure devices such as Voice over IP (VoIP) phones.
B.
Because APs are deployed across a Layer 3 boundary from the MSM Controller, they must be
pre-provisioned with static IP addresses.
C.
The company should create a DHCP scope that includes DHCP option 43. the IP address of
the controller, and the vendor code equal to 1.
D.
The company should configure the controller to assign IP addresses to the APs.
C is a good option

B is correct
Specific IP discovery: This method needs to be used when you do not have control over
the DHCP and DNS servers and no domain is registered to the controller. For example,
if the connection to the controller is routed over the public Internet.
Controller
AP
102.27.3.42 35.12.33.57
Provisioned to discover
the controller at the
address 102.27.3.42
For discovery to succeed, the AP must be provisioned with the controller IP address.
