   A manufacturing company is planning an SD-WAN deployment. The application dependency mapping reveals that the enterprise resource planning (ERP) system at headquarters depends on a database server in the data center, which in turn replicates to a secondary data center. The ERP client at a branch office connects to the primary database via a specific port. The team is unsure if the ERP traffic is being correctly identified in the current traffic analysis. What is the most critical piece of information to validate during the application dependency mapping?

   • ADetermine the total bandwidth used by all applications at the branch office to ensure the WAN link is sized correctly.
   • BConfirm the exact IP addresses and ports used by the ERP client to reach the primary database, and verify that the replication traffic between data centers is separate.
   • CDocument the physical location of the ERP server and the database server in the data center.
   • DIdentify the vendor of the ERP application to determine if it has known SD-WAN integration issues.

   A logistics company is assessing its network for SD-WAN readiness. The inventory team has a spreadsheet of WAN links, but the data is six months old. During a site visit to a regional distribution center, they find that the primary MPLS circuit was replaced with a 1 Gbps broadband connection, and a new LTE modem was added as a backup. The old spreadsheet still lists the MPLS circuit as active. What is the most appropriate immediate action for the assessment team?

   • ANote the discrepancy in the final report but continue using the spreadsheet data as the baseline for the SD-WAN design.
   • BUpdate the inventory spreadsheet with the new broadband and LTE details, and mark the MPLS circuit as decommissioned.
   • CAsk the site manager to confirm the change in writing before updating the inventory.
   • DKeep the MPLS circuit in the inventory as a 'planned' link in case the company decides to re-add it later.

   What is the purpose of application dependency mapping in an SD-WAN assessment?

   • ATo list all applications installed on end-user devices
   • BTo determine the cost of licensing each application
   • CTo identify which applications depend on which network resources and their performance needs
   • DTo measure the physical distance between data centers

   A university is assessing its network for SD-WAN. The management and operations review reveals that the network team uses a combination of spreadsheets, a legacy CLI-based monitoring tool, and manual change requests to manage the WAN. The team wants to understand how SD-WAN will change their operational workflows. What is the most important operational aspect to evaluate during this review?

   • AThe physical location of the network operations center (NOC).
   • BThe number of network engineers on the team and their individual job titles.
   • CThe team's current change management process and how it will need to adapt to the centralized, policy-based management of SD-WAN.
   • DThe brand of the existing monitoring tool and whether it is compatible with the SD-WAN vendor's API.

   What is the main purpose of traffic flow analysis in an SD-WAN readiness assessment?

   • ATo determine the cost of each WAN link
   • BTo identify the physical location of all network devices
   • CTo understand current bandwidth usage and application patterns
   • DTo test the security of the network against external threats
