Question 10
At a design studio in Berlin, engineers report that a design treats the 802.3 Ethernet PHY rate as proof that a wireless station has authenticated. The work affects wireless workstations and video conferences. Which test result most directly confirms the required behavior?
Explanation
Correct Answer
This observation tests the 802.11, 802.1 and 802.3 protocol boundaries requirement at a design studio in Berlin. The expected result is that the trace and network design identify the correct standard for the failed behavior without treating wireless association as a wired port login. The necessary correction is to distinguish wireless 802.11 access, wired Ethernet 802.3 transport, and 802.1X port authentication before selecting the troubleshooting layer; a saved configuration alone would not prove it is working. In this case, the observed fault is that a design treats the 802.3 Ethernet PHY rate as proof that a wireless station has authenticated.
Incorrect Answers
At a design studio in Berlin, this measures a different network requirement, Ethernet frame, VLAN and IP layer interpretation. The case describes that a design treats the 802.3 Ethernet PHY rate as proof that a wireless station has authenticated, so accepting this result would leave the primary fault without direct verification.
At a design studio in Berlin, this would verify VLAN trunk and native VLAN consistency, not the failure reported in this scenario. The requested closure criterion instead concerns 802.11, 802.1 and 802.3 protocol boundaries: the trace and network design identify the correct standard for the failed behavior without treating wireless association as a wired port login. In this case, the observed fault is that a design treats the 802.3 Ethernet PHY rate as proof that a wireless station has authenticated.
At a design studio in Berlin, this measures a different network requirement, Ingress ACL enforcement and least privilege. The case describes that a design treats the 802.3 Ethernet PHY rate as proof that a wireless station has authenticated, so accepting this result would leave the primary fault without direct verification.
