A network engineer is troubleshooting a newly deployed wireless network that is using the latest 802.11 standards. When users access high bandwidth services such as streaming video, the wireless network performance is poor. To improve performance the network engineer decides to configure a 5 Ghz frequency band SSID and train users to use that SSID for streaming media services. Why might this solution improve the wireless network performance for that type of service?

Requiring the users to switch to the 5 GHz band for streaming media is inconvenient and will result in fewer users accessing these services.

The 5 GHz band has more channels and is less crowded than the 2.4 GHz band, which makes it more suited to streaming multimedia.

The 5 GHz band has a greater range and is therefore likely to be interference-free.

The only users that can switch to the 5 GHz band will be those with the latest wireless NICs, which will reduce usage.

MAC address of the virtual router

MAC address of the standby router

MAC addresses of both the forwarding and standby routers

MAC address of the forwarding router

After a host has generated an IPv6 address by using the DHCPv6 or SLAAC process, how does the host verify that the address is unique and therefore usable?

The host sends an ICMPv6 echo request message to the DHCPv6 or SLAAC-learned address and if no reply is returned, the address is considered unique.

The host sends an ICMPv6 neighbor solicitation message to the DHCP or SLAAC-learned address and if no neighbor advertisement is returned, the address is considered unique.

The host checks the local neighbor cache for the learned address and if the address is not cached, it it considered unique.

The host sends an ARP broadcast to the local link and if no hosts send a reply, the address is considered unique.

Match the purpose with its DHCP message type. (Not all options are used.)
