in question 272 the right answer states that an autonomous acces point is "configured and managed by the wlc" but this is not what i have learned in my ccna course. is this a mistake? i understand that lightweight aps are managed by wlc while autonomous work as standalones on the wlan.

52 should be b&c. controller failure has nothing to do with this type of issue. degraded state tells us its a raid issue, and if the os is missing then the bootable device isnt found. the only other consideration could be data loss but thats somewhat broad whereas b&c show understanding of the specific issues the question is asking about.
