Question 500
A branch design for Riverside Data has two requirements: (1) select three nonoverlapping 20-MHz 2.4-GHz Wi-Fi channels in a common regulatory domain, and (2) distinguish a directed broadcast from an ordinary host IP. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) These nominal 20-MHz channel centers reduce adjacent-channel overlap in 2.4 GHz. (2) The all-ones host portion represents the subnet-directed broadcast in ordinary IPv4 subnets. Neither action is a substitute for the other.
Incorrect Answers
The second step covers (2), but the first addresses verify that an IPv6 interface has a link-local address. Link-local addresses are used for on-link neighbor discovery and routing adjacencies. It leaves outcome (1) unfulfilled.
The first step covers (1), but the second addresses diagnose rising CRC/FCS errors on one access port. Corrupt Ethernet frames commonly indicate physical media, cabling, or signaling faults. It leaves outcome (2) unfulfilled.
Neither step is the requested pair: Recognize an FE80::/10 address with outgoing-interface context is for identify an IPv6 link-local next hop, and Flood to other forwarding ports in that VLAN is for handle an unknown unicast destination received on one VLAN. A link-local IPv6 address is only meaningful on its link and may require an interface zone. The proposed plan misses the two stated outcomes.
