A medium-sized hospitality company with 50 hotels needs to upgrade the existing WLAN in each hotel to 802.11n. During the site surveys for each hotel, what needs to be taken into consideration when determining the locations for each AP?
A.
Selecting APs that can be hidden in ceiling panels to provide a secure and clean aesthetic look.
B.
Selecting locations that make visual assessment of the AP operation easy.
C.
Selecting locations that are easily accessed so maintenance and upgrades can be performed quickly.
D.
Selecting AP locations where power is already available.
A - ‘Also, these are usually public places and thus susceptible to theft and vandalism. A common requirement is to properly secure APs to ceilings or walls or to hide them above the ceiling.’ ‘Hotels also have many of the same concerns as hospitals regarding aesthetics. APs may need to be hidden in the walls or ceiling, where possible, or behind elements of the furniture.’ Official Cert Guide, Ch.2. P.30. para.7. & P.31. para.2.
I would say A. While D seems to be the chosen answer by the website, most modern-day switches have PoE so power shouldn't be a huge concern with an AP. We also don't want the AP out in plane site for security reasons.
It is not A, please, please, please, you should never hide an AP in a ceiling unless you are using external antenna with it. There are lockable enclosures that can ensure security. In-ceiling mountings create horrible RF characteristics (nearside reflections off of ductwork, pipes, etc) and can be a nightmare to find during an upgrade or troubleshooting, also many times the mounting might have "overlooked", I have seen APs thrown on top of ceiling tiles just waiting to drop on someone or crammed next in the electrical wires.
This question is pretty poorly worded though, choice D is also false as most APs should be accommidated by POE, so a power supply should not be a factor. So is it B or C? Probably should be both.
