Selected Answer: B

Answer is correct. A is not correct, if the hash key would be wrong, control path wouldnt come up in the first place. C is not correct. Secure Mobility is enabled by default on 9800 and therefore needs to be enabled on aireos. keyword is 'encrypt enable' on 2nd Line of AireOS konfig. D is not correct. case-sensitive doesnt matter. So B is the answer. Though on 9800 config there is an error: wireless mobility mac-address is with wrong mac. Should be 9800 own mac-address configured.
