SD-WAN Engineer Practice Exam 2025: Latest Questions

An organization is planning an SD-WAN rollout to 40 branches. The WAN circuits at branches will vary widely in quality, and the business wants the SD-WAN fabric to prefer the best-performing path for voice and video without manual, site-by-site tuning. Which design approach best meets this requirement?

A branch has two ISP circuits. The business requirement is: "If one circuit fails, all traffic must continue over the remaining circuit with minimal interruption." Which SD-WAN capability most directly fulfills this requirement?

While deploying Prisma SD-WAN at a new branch, you want to reduce provisioning errors and standardize WAN interfaces, zones, and base security settings across all branches. What is the recommended method?

A network operator needs to verify that an SD-WAN policy is steering Microsoft Teams traffic over the low-latency circuit at a branch. Which operational check is most appropriate?

After enabling SD-WAN, a branch reports that business-critical SaaS traffic intermittently uses the backup broadband link even though the primary link is up. Monitoring shows short bursts of latency on the primary link. What is the most likely explanation?

A company is migrating to a dual-exit model: internet-bound traffic should break out locally at branches, while internal applications must go to headquarters. Which SD-WAN policy approach best supports this requirement?

During deployment, you must ensure that SD-WAN only steers traffic for a defined set of applications, and all other traffic follows traditional routing. Which configuration approach best meets this requirement?

A branch uses two circuits, and users complain that large file transfers sometimes degrade voice quality. You already have SD-WAN path selection configured correctly. What additional configuration is most likely needed to protect voice during congestion?

After integrating a branch with SASE for secure internet access, users report intermittent access failures to a SaaS application. The SD-WAN fabric is stable, and general internet access works. Which troubleshooting step is MOST appropriate to isolate whether the issue is due to SASE policy enforcement rather than SD-WAN path selection?

A new SD-WAN rule is intended to steer ERP traffic over MPLS when the MPLS link meets SLA, otherwise use broadband. However, ERP sessions continue to use broadband even when MPLS metrics are good. Link monitoring shows MPLS is healthy. Which is the MOST likely root cause?

An enterprise is planning an SD-WAN rollout to 40 branches. A key requirement is that only business-critical applications use the dedicated MPLS link, while all other traffic prefers broadband. Which SD-WAN design approach best meets this requirement?

A branch has two WAN circuits. Users complain that voice quality degrades intermittently, even though both links show low bandwidth usage. Which SD-WAN metric is most directly relevant to voice quality and should be used in path selection?

After enabling SD-WAN on a branch firewall, an administrator wants to validate that SD-WAN rules are actively making forwarding decisions. What is the most appropriate place to confirm SD-WAN rule matches and selected paths?

A company wants to migrate branches from traditional hub-and-spoke to SD-WAN with minimal disruption. Branches must continue to reach data center subnets during the transition, and the team wants centralized control of branch connectivity. Which phased approach is most appropriate?

A branch has two internet links and uses SD-WAN to steer Office 365 traffic. Users report that traffic occasionally takes the wrong path after a link flap. The administrator suspects inconsistent application identification during the first few packets of a session. What configuration best improves consistent steering for SaaS applications?

An administrator needs to ensure that business-critical traffic fails over within seconds when packet loss exceeds a threshold, but should not flap when transient loss occurs. Which SD-WAN configuration approach best addresses this requirement?

A branch uses SD-WAN with two transports: broadband and LTE. The goal is to use LTE only as a last resort due to limited data. Which configuration best enforces this behavior while still maintaining resiliency?

A network operations team wants to reduce mean time to resolution by quickly determining whether user complaints are caused by WAN path degradation or by application server issues. Which operational practice best supports this goal in an SD-WAN environment?

A branch is integrated with Prisma Access for security inspection. Users report intermittent inability to reach internal applications hosted in the data center after enabling SD-WAN. Internet access works normally. Which is the most likely SD-WAN-related cause?

A site uses SD-WAN with two active links. During an outage simulation, the team observes that new sessions fail over correctly, but existing long-lived TCP sessions stall for several minutes after the preferred path degrades. Which design adjustment most directly improves continuity for existing sessions during path changes?

A retail company is planning an SD-WAN rollout to 60 small branches. Most sites have commodity internet only, and the company wants to minimize operational overhead while ensuring each site can establish secure overlays without manual VPN configuration. Which design choice best supports these requirements?

An organization uses SD-WAN with two WAN links per branch (broadband and LTE). They want voice and video traffic to prefer broadband but automatically shift to LTE when broadband quality degrades, without failing over all traffic. Which configuration best meets this requirement?

You are investigating intermittent application complaints from a branch. The SD-WAN dashboard shows the branch is frequently changing paths for a business-critical app even though both links appear up. Which is the most likely configuration issue to check first?

A company is integrating SD-WAN branches with a cloud-delivered security service for internet-bound traffic. They want to ensure that only specific application categories (for example, social media and streaming) are sent to the cloud security service while other internet traffic breaks out locally. Which approach is most appropriate?

After deploying SD-WAN, a branch reports that traffic to a data center subnet is sometimes taking the incorrect WAN path, even though an SD-WAN policy exists for that subnet. The policy matches the correct destination, but behavior is inconsistent across new and existing sessions. What is the most likely explanation?
