Question 370
An acceptance check at North Quay Finance has two requirements: (1) shut an edge port immediately if an unexpected switch BPDU arrives, and (2) assign different WLAN client traffic to an approved wired segment. Which proposed plan satisfies both outcomes?
Explanation
Correct Answer
Both outcomes are covered: (1) BPDU Guard error-disables a protected edge port receiving a BPDU to prevent accidental loops. (2) Controller WLAN-to-VLAN mapping determines the wired broadcast domain for client data. Neither action is a substitute for the other.
Incorrect Answers
Neither step is the requested pair: Select the switch with the lowest priority plus MAC bridge identifier is for identify the spanning-tree root switch from bridge IDs, and Configure spanning-tree portfast on a true endpoint-facing access port is for enable rapid host access without waiting for ordinary STP transitions. STP elects the lowest bridge ID as the root for a spanning-tree instance. The proposed plan misses the two stated outcomes.
The first step covers (1), but the second addresses publish a wireless network name for corporate users from a WLC. The WLAN profile binds an SSID to its wireless security and policy configuration. It leaves outcome (2) unfulfilled.
The second step covers (2), but the first addresses reject unsecured wireless client associations on a protected SSID. A secure SSID must negotiate the configured credentials and cipher before passing client data. It leaves outcome (1) unfulfilled.
