Several users are reporting connectivity issues with their laptops. Upon further investigation, the
network technician identifies that their laptops have been attacked from a specific IP address
outside of the network. Which of the following would need to be configured to prevent any further
attacks from that IP address?

A.
Port security

B.
IDS

C.
Firewall rules

D.
Switch VLAN assignments

Explanation:
Firewall rules block or allow specific traffic passing through from one side of the
router to the other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources,
selectively allowing only specific outside users to access specific resources. Outbound rules (LAN
to WAN) determine what outside resources local users can have access to.
