Exam PCNSA topic 1 question 122 discussion

is correct

C is correct. Application groups are static not dynamic.

An application filter is an object that dynamically groups applications based on application attributes that you select from the App-ID database. [Palo Alto Networks]

C, Filters are dynamic and can be added to a app group. App groups can also be added to other app groups

answer B Nesting Application Groups and Filters An administrator can nest application groups and filters. Multiple applications and multiple application filters can be combined into an application group. One or more application groups then also can be combined into one application group. The final application group then can be added to a Security policy rule.

An administrator can dynamically categorize multiple applications into an application filter based on the specific attributes Category, Subcategory, Tags, Risk, and Characteristic. For example, if you want to allow all audio streaming applications, you could create an application filter that includes the subcategory of audio-streaming, which automatically would add all applications to the filter from the App-ID database that are subcategorized as audio-streaming. The filter then would be added as an application to a Security policy rule. Application filters simplify the process of ensuring that all applications that meet any attribute automatically are added to a Security policy.
