In Prisma Access, how does backbone routing benefit network performance?

Question

Options

• AIt provides optimized, low-latency routing between different Prisma Access locations
• BIt enables direct connections between mobile users and remote networks
• CIt forces all traffic through a centralized firewall instance
• DIt reduces the need for authentication checks on incoming traffic

• A
  88% (36)
• B
  7% (3)
• C
  2% (1)
• D
  2% (1)

Explanation

Option A is correct because Prisma Access uses a global backbone network - Palo Alto Networks' cloud infrastructure - to intelligently route traffic between its distributed nodes (Service Connections, Remote Networks, and Mobile User gateways), avoiding the congestion and unpredictability of the public internet and dramatically reducing latency.

Why the distractors are wrong:

• B is incorrect because backbone routing optimizes traffic between Prisma Access nodes, not between end users and remote networks directly - mobile users still connect to the nearest gateway first.
• C is the opposite of backbone routing's purpose; centralized choke-pointing increases latency, whereas the backbone distributes and optimizes traffic flows.
• D is incorrect and dangerous in concept - backbone routing is a performance mechanism, entirely separate from authentication, which Prisma Access still enforces.

Memory tip: Think of the backbone as a private highway system connecting Prisma Access locations - just like a toll road bypasses city traffic, the backbone bypasses the congested public internet to deliver faster, more reliable inter-site routing.
