This is an ASA 551X device with Security Plus License version 9.9.2
Memory Size is 4Gb RAM & 8Gb Flash
The Security+ License in a 5515X provides some features not available with a Base License.
For instance, you'll get features like High Availability through Stateful Active/Active Failover, Multiple Security Contexts, AnyConnect Client Support, etc.
NOTE:
A Security Plus License enables the AnyConnect Premium License. However, Cisco has changed the name AnyConnect Premium to AnyConnect APEX License.
This change was made because Cisco also offers an
AnyConnect PLUS License (also called Essentials).
Please check out this Link for more information about AnyConnect PLUS and APEX:
So a Security Plus License with AnyConnect APEX provides more features than AnyConnect Plus.
For instance, it implements Stateful Active/Active Failover providing up to 5 Security Contexts
2 Security Contexts are added by default. Additional Licenses are needed for more Sec. Contexts.
The CCNA Security Exam doesn't include Stateful Active/Active Failover. But this Topic is part of the CCNP Security Exam! Therefore, an upgrade to ASA 5515X with Security Plus Lic. would be recommended if you plan to move on to CCNP Security later on.
