A system administrator wants to provide for and enforce wireless access accountability during events where external speakers are invited to make presentations to a mixed audience of employees and non-employees. Which of the following should the administrator implement? A. Shared accountsB. Preshared passwordsC. Least privilegeD. Sponsored guest

C. and D.

Explanation:

We cannot really share anybody account details and password of such a level of speaker with anybody. Their privacy needs to be respected. Hence, we cannot share their accounts or provide them Preshared password.

We need to provide them however, only some privilege and nothing more than that, as our organization privacy and security of top secret information, from any outsiders, And the external speakers are definitely outsiders, And since then need to be paid as well, and hence we need to rate them as sponsored guest.

That explains the above answer.
