A customer is planning to deploy HP MSM466-R access points in an extreme cold
environment to interconnect to the Unified Wired-WLAN Module in the HP switch. Which
requirement is needed to accomplish this?

A.
NEMA 4X enclosures should be used to house the access points.

B.
Switch ports must support PoE.

C.
PoE redundancy must be enabled on the interface.

D.
Access Point must deploy internal antennas.

Explanation:
Preventing untagged packets on the physical interface—If you use subinterfaces, you
typically do not also want the physical interface to pass traffic, because the physical interface
passes untagged packets. This property is also true for the active physical interface in a
redundant interface pair. Because the physical or redundant interface must be enabled for
the subinterface to pass traffic, ensure that the physical or redundant interface does not pass
traffic by leaving out the nameif command. If you want to let the physical or redundant
interface pass untagged packets, you can configure the nameif command as usual. See the
“Completing Interface Configuration (All Models)” section for more information about
completing the interface configuration.
