A network administrator of a global organization is collapsing all controllers to a single cluster located in central Europe. Which concern must be addressed?
A.
Some channels may not be available consistently across the organization.
B.
Different RF policies per office are not available in this configuration.
C.
Syslog must be configured to the time-zone of the NMS platform.
D.
Centralized controllers cannot uniformly authenticate global users.
This is a global org hence clustering all WLCs in central EU will require the admin to specify the country codes to manage APs in various countries from a single WLC and ensure regulatory compliance.

so it says address the concern which A is a concern that needs to be taken into account, syslog is not restricted but if there is a channelling issue that's something to be concerned about
The question is "Which concern must be addressed", therefore the correct answer will be A.
Configuring country codes seems to address that concern: https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-5/config-guide/b_cg85/country_codes.html
I just looked it up, but you can actually change the channels allowed on a per RF Profile basis, which would allow restriction of channels in the needed regions. The original answer is legit.
Answer A says "available CONSISTENTLY". So the it's not that channels can't be used at all, but rather, it has to be costomized through RF Profile per each AP group.
Correct answer would be A
