You are asked to implement a wireless network for a conference center and need to provision a high number of access points to support a large number of wireless client connections.
Which statement describes a valid solution for this requirement?

A.
Use a captive portal for guest access. Use both 2.4 GHz and 5 GHz bands. Enable frequency and access
point hand-off. Use more channels, thereby supporting more clients.

B.
Use an open wireless network with no portal. Use both 2.4 GHz and 5 GHz bands. Use 802.11ac capable
access points and configure channel bonding to support greater throughput for wireless clients.

C.
Use a pre-shared key only for wireless client security. Use the 5 GHz band only for greater security. Use
802.11ac capable access points and configure channel bonding to support greater throughput for wireless
clients.

D.
Use a captive portal for guest access. Use both the 2.4 GHz and 5 GHz bands, and configure frequency
steering. Configure rogue access point detection in order to automatically control the transmit power of each
AP.
