ASA Resource Management in Multiple Context Mode

AD.

ASA (Adaptive Security Appliance) is a security device that provides network protection by inspecting traffic flows and enforcing security policies. It offers multiple context mode that enables the ASA to divide its resources into multiple virtual firewalls or contexts.

Here are the explanations for the given options:

A. The class sets the resource maximum limit for a context to which it belongs. This statement is correct. In the multiple context mode, resource management is done using resource classes. A resource class is a group of contexts with the same resource limits. The class sets the maximum limit for the resources that can be used by the contexts that belong to it.

B. A resource cannot be oversubscribed or set to be unlimited in the class. This statement is incorrect. A resource can be oversubscribed in the class, but it may lead to performance issues. Also, a resource can be set to unlimited, which means that there is no limit to the resource usage.

C. The resource limit can only be set as a percentage in the class and not as an absolute value. This statement is incorrect. The resource limit can be set as an absolute value or as a percentage of the total available resources.

D. Context belongs to a default class if not assigned to any other class. This statement is correct. If a context is not assigned to any resource class, it belongs to the default resource class.

E. The default class provides unlimited access for all the resources. This statement is incorrect. The default class has resource limits, and if a context belongs to the default class, it can use the resources within those limits.

In summary, options A and D are correct statements that describe ASA resource management in multiple context mode.
