Question 420
An operations ticket for Stonebridge Learning has two requirements: (1) deliver predictable east-west paths among multiple data-center racks, and (2) apply stateful application-aware inspection at the edge. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) Each leaf reaches other leaves through spine devices, reducing variable hop counts. (2) A next-generation firewall can classify application traffic and track sessions before permitting flows. Neither action is a substitute for the other.
Incorrect Answers
Neither step is the requested pair: Insert FFFE and invert the universal/local bit at the defined location is for form a modified EUI-64 interface identifier from a 48-bit MAC, and Use the service set identifier or SSID is for identify the broadcast identifier clients select to join a WLAN. Modified EUI-64 expands the 48-bit MAC and flips the U/L bit to form a 64-bit identifier. The proposed plan misses the two stated outcomes.
The second step covers (2), but the first addresses display the IPv6 forwarding table on a Cisco router. The IPv6 routing table exposes connected, static and learned IPv6 destinations. It leaves outcome (1) unfulfilled.
The first step covers (1), but the second addresses hold independent overlapping IP route tables on one router. VRFs logically isolate routing tables even when interfaces share one physical platform. It leaves outcome (2) unfulfilled.
