   A government agency is assessing its network for SD-WAN. The inventory team is cataloging all WAN links. They find that some links are provided by a third-party contractor who manages the circuits and provides a monthly report. The report lists the circuit IDs and bandwidth, but not the actual performance data. The agency needs to determine if these links are suitable for SD-WAN. What is the most appropriate action for the inventory team?

   • ARequest the performance data from the contractor, and if unavailable, plan to conduct active performance testing on the links.
   • BExclude the contractor-managed links from the inventory because the agency does not have direct access to them.
   • CAccept the contractor's report as sufficient and include the links in the inventory with the listed bandwidth.
   • DAssume the links are not suitable for SD-WAN because they are managed by a third party.

   A hospital network is assessing its WAN for SD-WAN. The current architecture uses a single MPLS link from each clinic to the main hospital. The assessment team is evaluating high availability requirements. The hospital's electronic health record (EHR) system is critical and must remain available. The team is considering adding an LTE link as a backup. What is the most important factor to consider when assessing the LTE link for high availability?

   • AThe brand of the LTE modem provided by the carrier.
   • BThe LTE link's expected uptime and failover characteristics, including how quickly it can become active if the MPLS link fails.
   • CThe physical location of the LTE antenna on the clinic's roof.
   • DThe cost of the LTE data plan compared to the MPLS link.

   What is the purpose of a security posture review in an SD-WAN assessment?

   • ATo inventory all security certificates in use
   • BTo test the network's resistance to DDoS attacks
   • CTo evaluate the current security architecture and identify integration points for SD-WAN
   • DTo determine the physical security of data centers
