   A financial firm has two links to its trading platform: a primary MPLS link and a backup internet link. The trading application is sensitive to both latency and jitter. The firm wants to use the MPLS link as long as its latency is below 50 ms AND jitter is below 10 ms. If either metric exceeds its threshold, traffic should move to the backup link. The administrator has created an SLA profile with both thresholds. What must be configured to ensure the MPLS link is only used when BOTH metrics are within limits?

   • ACreate two separate SLA profiles, one for latency and one for jitter, and reference both in the routing policy.
   • BSet the SLA probe interval to 50 seconds and the jitter threshold to 10 ms in the routing policy.
   • CConfigure the routing policy to use the backup link as the primary path and the MPLS link as the backup.
   • DReference the SLA profile in the SD-WAN routing policy for the MPLS link, which will evaluate both metrics and mark the link ineligible if either threshold is exceeded.

   In a Palo Alto Networks SD-WAN setup, what happens when a link's measured latency exceeds the threshold defined in an SLA policy?

   • AThe firewall restarts the link's interface
   • BThe firewall may select a different path that meets the SLA requirements
   • CThe firewall blocks all traffic on that link
   • DThe link is immediately removed from the configuration

   What is the purpose of an SLA policy in a Palo Alto Networks SD-WAN configuration?

   • ATo define performance thresholds that a link must meet to be considered healthy
   • BTo create security rules for traffic inspection
   • CTo assign IP addresses to WAN interfaces
   • DTo specify the encryption method for data transmitted over the WAN

   A branch office has two WAN links: a low-latency MPLS link and a high-bandwidth broadband link. The company wants video conferencing traffic to use the MPLS link when its latency is below 80 ms, but to fall back to the broadband link when latency exceeds that. What is the correct way to implement this in the SD-WAN configuration?

   • ACreate an SLA profile with an 80 ms latency threshold and an SD-WAN routing policy for video traffic that references it.
   • BConfigure the broadband link as the primary path in the routing policy and the MPLS link as the backup.
   • CSet the SLA probe interval to 80 seconds and apply it to the video traffic policy.
   • DCreate a static route for video traffic via the MPLS link and a backup route via the broadband link.
