Question 290
An HPE Aruba Networking design review examines: A printer cannot run 802.1X but must stay in a limited wired segment. Which technical principle BEST explains the required approach?
Explanation
Correct Answer
Special endpoints need explicit constrained fallback, not blanket open ports. The case therefore calls for this specifically controlled action: use a governed MAC authentication or approved alternate access method with restrictive role. The acceptance evidence is that the printer can reach necessary services but not employee-only networks.
Incorrect Answers
This principle choice fits a different situation: A campus must reduce DHCP spoofing and unauthorized access to endpoint address information. It does not resolve the stated failure mode. For this case, the decisive principle choice is to special endpoints need explicit constrained fallback, not blanket open ports.
This principle choice fits a different situation: A user VLAN must not access a sensitive server subnet. It does not resolve the stated failure mode. For this case, the decisive principle choice is to special endpoints need explicit constrained fallback, not blanket open ports.
This principle choice fits a different situation: Employee switch ports require 802.1X authentication against an identity service. It does not resolve the stated failure mode. For this case, the decisive principle choice is to special endpoints need explicit constrained fallback, not blanket open ports.
