Exam PSE-Strata-Pro-24 Topic 1 Question 30 Discussion

Segregating a network into unique BGP environments requires the ability to configure separateeBGP autonomous systems(AS) within the NGFW. Palo Alto Networks firewalls support advanced BGP features, including the ability to create and manage multiple autonomous systems.
* Why "It can be addressed by creating multiple eBGP autonomous systems" (Correct Answer B)?
PAN-OS supports the configuration of multiple eBGP AS environments. By creating unique eBGP AS numbers for different parts of the network, traffic can be segregated and routed separately. This feature is commonly used in multi-tenant environments or networks requiring logical separation for administrative or policy reasons.
* Each eBGP AS can maintain its own routing policies, neighbors, and traffic segmentation.
* This approach allows the NGFW to address the customer's need for segregated internal BGP environments.
* Why not "It cannot be addressed because PAN-OS does not support it" (Option A)?This statement is incorrect because PAN-OS fully supports BGP, including eBGP, iBGP, and features like route reflectors, confederations, and autonomous systems.
* Why not "It can be addressed with BGP confederations" (Option C)?While BGP confederations can logically group AS numbers within a single AS, they are generally used to simplify iBGP designs in very large-scale networks. They are not commonly used for segregating internal environments and are not required for the described use case.
* Why not "It cannot be addressed because BGP must be fully meshed internally to work" (Option D)?Full mesh iBGP is only required in environments without route reflectors. The described scenario does not mention the need for iBGP full mesh; instead, it focuses on segregated environments, which can be achieved with eBGP.
