A junior network administrator was given the task of configuring port security on SwitchA to allow
only PC_A to access the switched network through port fa0/1. If any other device is detected, the

successful pings from PC_A to RouterA, and then observes the output from these two show
commands.
Which two of these changes are necessary for SwitchA to meet the requirements? (Choose two.)

Statements A, B, C, and D of ACL 10 have been entered in the shown order and applied to
interface E0 inbound, to prevent all hosts (except those whose addresses are the first and last IP
of subnet 172.21.1.128/28) from accessing the network. But as is, the ACL does not restrict
anyone from the network. How can the ACL statements be re-arranged so that the system works
as intended?
