Refer to the exhibit. A network administrator is configuring the security level for the ASA. What is a best practice for assigning the security level on the three interfaces?
- Outside 40, Inside 100, DMZ 0
- Outside 0, Inside 35, DMZ 90
- Outside 100, Inside 10, DMZ 40
- Outside 0, Inside 100, DMZ 50
Explanation: The Cisco ASA assigns security levels to distinguish among different networks it connects. Security levels define the level of trustworthiness of an interface. The higher the level, the more trusted the interface. The security level numbers range between 0 (untrustworthy) to 100 (very trustworthy). Therefore, the interface connecting to the Internet should be assigned the lowest level. The interface connecting to the internal network should be assigned the highest level. The interface connecting to the DMZ network should be assigned a level between them.
