You are the security administrator for a small business. The floor plan for your organization is shown in the figure below. You've hired a third-party security consultant to review your organization's security measures. She has discovered multiple instances where unauthorized individuals have gained access to your facility, even to very sensitive areas. She recommends that you provide employees with access badges and implement access badge readers to prevent this from happening in the future. Click on the office locations where access badge readers would be most appropriate.

Access badge readers are typically implemented at building entrances to control access to a facility. Only individuals who have an authorized access badge are allowed to enter the facility. Individuals who do not have an access badge must be cleared and admitted by security personnel. Additional access badge readers can be implemented within the facility to further restrict access to sensitive areas, such as the server room. References TestOut Security Pro - 3.1 Physical Threats

5.13.6 The Fiji router has been configured with Standard IP Access List 11. The access list is applied to the Fa0/0 interface. The access list must allow all traffic except traffic coming from hosts 192.168.1.10 and 192.168.1.12. However, you've noticed that it's preventing all traffic from being sent on Fa0/0. You remember that access lists contain an implied deny any statement. This means that any traffic not permitted by the list is denied. For this reason, access lists should contain at least one permit statement or all traffic is blocked. In this lab, your task is to: Add a permit any statement to Access List 11 to allow all traffic other than the restricted traffic. Save your changes in the startup-config file.

Complete this lab as follows: Enter the configuration mode for the Fiji router: From the exhibit, select the Fiji router. From the terminal, press Enter. Type enable and then press Enter.
