Which show command will display only the Type 5 LSAs in the OSPF topology database? Select the best response.

When the client sends a probe request in the 2.4 GHz band, the AP may reply with information about
the 5 GHz BSS. ✘ The AP may ignore the initial probe requests or 802.11 authentication requests sent in the 2.4 GHzband by dual-band clients ✘ The AP may allow an 802.11 association with the client in the 2.4 GHz band, then send unicast channelswitch announcements to the client announcing the 5 GHz channel as the new channel. ✘ After receiving probe request frames from the same client in both bands, the AP may send anassociation request frame to the client in the 5 GHz band. ✔ The AP may allow an 802.11 association with the client in the 2.4 GHz band, then the AP may perform atransparent client handoff by transferring the client's MAC address to the 5 GHz radio. ✔

Which attribute must exist in the BGP update packet? Select the best response.

802.11a and 11n use six (6) "pilot" subcarriers as a reference for the receiver to detect frequency and
phase shifts of the signal. ✘ 802.11a/g/n OFDM includes several combinations of modulation and coding to achieve data rates from1-600 Mbps. ✘ With 802.11a OFDM, 16-QAM provides either 48 or 54 Mbps data rates, depending upon coding rates. ✘ 802.11n HT-OFDM utilizes 256-QAM, which increases the data rate from 54 Mbps (with 64- QAM) up to65 Mbps. ✔ In 802.11a OFDM, forty-eight (48) subcarriers are used as parallel symbol transmission paths to carrydata. ✔
