Now that you have reviewed the available VPN connectivity methods provided by the ASA, their comparison and the path taken by a packet through the ASA device, it is time to take a look at the licensing models available. When it comes to licensing on the ASA, a lot of information is involved. I suggest using the following information as a handy reference instead of trying to memorize all of it. You might be required to know the result of combining two matching licenses (for example, on two devices during a failover configuration). However, the majority of the information provided here is for your information only and will not be included on the exam.
You can view your currently installed and active licenses on the ASA by navigating to Configuration > Device Management > Licensing > Activation Key within the ASDM, or by issuing the show version command when working from the command-line interface (CLI).
