Question 1150
A change advisory for Orion Shipping has two requirements: (1) explain why indiscriminate BPDU filtering risks a bridging loop, and (2) discover a neighboring Cisco switch's device name and management address. Which proposed plan satisfies both outcomes?
Explanation
Correct Answer
Both outcomes are covered: (1) Suppressing BPDUs can hide redundant links from spanning-tree loop prevention. (2) CDP exchanges Cisco neighbor information at Layer 2, including platform and management identifiers. Neither action is a substitute for the other.
Incorrect Answers
The first step covers (1), but the second addresses identify the spanning-tree root switch from bridge IDs. STP elects the lowest bridge ID as the root for a spanning-tree instance. It leaves outcome (2) unfulfilled.
Neither step is the requested pair: Configure an appropriate WPA2/WPA3-Enterprise WLAN with RADIUS is for enforce per-user identity authentication for an enterprise WLAN, and Use HTTPS management instead of unencrypted HTTP is for secure browser-based device administration on a WLC. Enterprise WLAN security uses 802.1X/EAP against an authentication server. The proposed plan misses the two stated outcomes.
The second step covers (2), but the first addresses carry multiple VLANs between distribution and access switches. An 802.1Q trunk tags most VLAN frames so several VLANs can share one interswitch link. It leaves outcome (1) unfulfilled.
