which one of these actions should you take?

You replaced your Layer 3 switch, which is the default gateway of the end users. Many users

cannot access anything now, including email, Internet, and other applications, although other
users do not have any issues. All of the applications are hosted in an outsourced data center. In
order to fix the problem, which one of these actions should you take?

A.
Clear the MAC address table in the switch.

B.
Clear the ARP cache in the switch.

C.
Clear the ARP cache in the end devices.

D.
Clear the ARP cache in the application servers.

Explanation:
Each workstation has its own arp cache. To delete the arp cache on a windows desktop do the
following:
1. Open the “Command Prompt, ” the Windows application that enables running Windows
commands and software applications, by clicking the Windows “Start” button, clicking “Programs, “
clicking “Accessories” and then clicking “Command Prompt.”
2. Type “netsh interface ip delete arpcache” in the Command Prompt to clear your ARP cache.
3. Type “arp -a” in the Command Prompt to verify that the ARP cache was cleared. The output of
this command should be “No ARP Entries Found.”
