   In a Prisma SD-WAN NAT policy, what does 'source NAT' (SNAT) typically accomplish?

   • AIt changes the destination IP address of incoming packets to route them to an internal server.
   • BIt selects the best WAN link for the traffic based on SLA.
   • CIt blocks traffic from untrusted zones.
   • DIt changes the source IP address of outgoing packets to a public address, allowing internal devices to access the internet.

   A company has two sites connected via Prisma SD-WAN. Site A uses a private IP range of 192.168.1.0/24, and Site B uses the same range. The administrator needs to allow servers at Site A to communicate with servers at Site B without changing the IP addresses on the servers. Which configuration should be used?

   • AEnable link aggregation on the WAN interfaces at both sites to combine the links and eliminate the conflict.
   • BCreate a path policy that forces traffic between the two sites over a specific WAN link to avoid the IP conflict.
   • CPlace both sites in the same zone and create a zone-based firewall rule that permits all traffic between them.
   • DConfigure a NAT policy on the Site A branch that translates the source IP addresses of traffic destined for Site B to a different subnet, and a corresponding reverse NAT policy on Site B.

   A company uses Prisma SD-WAN to connect its headquarters to a remote office. The remote office has two WAN links: a 100 Mbps MPLS link and a 500 Mbps broadband link. The company wants to maximize bandwidth for large file transfers while ensuring that VoIP traffic always uses the MPLS link for low latency. Which configuration should be used?

   • ACreate a single path policy that uses MPLS for all traffic to ensure low latency.
   • BConfigure a NAT policy to translate VoIP traffic to use the MPLS link.
   • CCreate a single path policy that uses broadband for all traffic to maximize bandwidth.
   • DCreate a path policy for VoIP that uses MPLS as the primary link, and a separate path policy for file transfers that uses both links with link aggregation to combine bandwidth.

   • BThe cost of the WAN link
   • CSource IP address of the user
   • DThe color of the WAN link

   A financial services firm uses Prisma SD-WAN to connect its headquarters to a trading floor. The trading application is sensitive to latency and jitter. The firm wants to ensure that if the primary MPLS link fails, traffic is automatically switched to a secondary link without disrupting the trading session. Which Prisma SD-WAN feature should be configured?

   • ASet up link aggregation on the primary and secondary links to combine them into a single logical link.
   • BConfigure a NAT policy to translate the trading application's source address to a different IP on the secondary link.
   • CEnable sub-second failover on the path policy that governs the trading application traffic.
   • DCreate a zone-based firewall rule that allows trading traffic on both links.
