Explanation:
A URL filter is used to block URLs (websites) to prevent users accessing the website.
Firewall rules act like ACLs, and they are used to dictate what traffic can pass between the firewall and the
internal network. Three possible actions can be taken based on the rule’s criteria:
Block the connection
Allow the connection
Allow the connection only if it is secured
Incorrect Options:
B: Role-based Access Control is basically based on a user’s job description. When a user is assigned a specific
role in an environment, that user’s access to objects is granted based on the required tasks of that role. Since
the sales team needs to save and print reports, they would not be restricted if restrictions were role-based.
C: A MAC filter is a list of authorized wireless client interface MAC addresses that is used by a WAP to block
access to all unauthorized devices.
D: Port security works at level 2 of the OSI model and allows an administrator to configure switch ports so that
only certain MAC addresses can use the port.
