The backup path reports valid quality and becomes eligible when the primary deteriorates. This would verify resolution of a different case: A site enables new SD-WAN path steering but omits probe reachability through its edge firewall and incorrectly flags every backup path as failed. It does not show that the reported issue was fixed or that its intended action—Move or recreate the approved profile at the correct supported scope and update the matching SD-WAN policy.—worked.

Voice sessions shift on quality degradation while bulk transfers follow their cost-appropriate policy. This would verify resolution of a different case: A branch uses one SD-WAN profile for backup transfers and video calls, resulting in expensive failovers for harmless bulk-traffic delay. It does not show that the reported issue was fixed or that its intended action—Move or recreate the approved profile at the correct supported scope and update the matching SD-WAN policy.—worked.

A controlled latency degradation produces the expected qualified path selection without oscillation. This would verify resolution of a different case: A primary circuit has intermittent latency spikes but an SD-WAN quality profile uses an overly insensitive threshold that never triggers. It does not show that the reported issue was fixed or that its intended action—Move or recreate the approved profile at the correct supported scope and update the matching SD-WAN policy.—worked.

Path-quality thresholds can treat any single breached metric as a disqualifier. This mechanism instead explains a separate problem: A voice path changes even when only packet loss exceeds its threshold, but an engineer expects all three SLA metrics to fail before failover. The current incident requires the more directly applicable cause stated by the correct option.

Traffic distribution without specific business match conditions can choose an unsuitable egress. This mechanism instead explains a separate problem: A link management rule selects a low-cost Internet path for payment transactions even though their regulated destination must use the private link. The current incident requires the more directly applicable cause stated by the correct option.

Saved cloud configuration is not evidence of active data-plane settings on the firewall. This mechanism instead explains a separate problem: A cloud-managed SD-WAN template changes a branch's interface role but was never pushed to the target firewall. The current incident requires the more directly applicable cause stated by the correct option.

Maintain application/destination path-policy tests for regulated services. That safeguard addresses another potential failure: A link management rule selects a low-cost Internet path for payment transactions even though their regulated destination must use the private link. It is not the most targeted recurring control for the described cause: Policy references must resolve within applicable management scope and inheritance.

Test each SLA dimension against representative critical-app traffic. That safeguard addresses another potential failure: A branch voice application fails during high jitter on the primary WAN link because its path-quality profile evaluates latency only. It is not the most targeted recurring control for the described cause: Policy references must resolve within applicable management scope and inheritance.

Review transport capacity and cost when selecting traffic distribution profiles. That safeguard addresses another potential failure: An SD-WAN traffic distribution policy round-robins traffic over paths of unequal capacity and overloads a small LTE backup link. It is not the most targeted recurring control for the described cause: Policy references must resolve within applicable management scope and inheritance.

Correct site scope and deploy the required supported SD-WAN tunnel configuration to the spoke. That could address a different issue in the same blueprint area: An SD-WAN policy pushes successfully but a new spoke lacks the expected tunnel because template activation targeted only a neighboring site. It does not directly correct the given incident, whose decisive mechanism is: A quality profile only affects flows that match its referencing SD-WAN policy.

Adjust traffic distribution and capacity settings for the new measured link bandwidth. That could address a different issue in the same blueprint area: A transport change updates one path's assigned bandwidth but SD-WAN policy still selects it for a larger load than the link can carry. It does not directly correct the given incident, whose decisive mechanism is: A quality profile only affects flows that match its referencing SD-WAN policy.

Configure the appropriate SD-WAN routing and tunnel dependencies for the selected path. That could address a different issue in the same blueprint area: A site enables SD-WAN tunnel path switching but the selected tunnel interface is missing the required routing/security configuration. It does not directly correct the given incident, whose decisive mechanism is: A quality profile only affects flows that match its referencing SD-WAN policy.

Voice sessions choose an approved qualified path based on policy and measured performance. This would verify resolution of a different case: A branch has a high-quality private link and degraded broadband link, but a hard-coded app route forces voice over broadband despite better available private connectivity. It does not show that the reported issue was fixed or that its intended action—Match the correct App-ID or approved application group in the SD-WAN rule.—worked.

Both paths measure realistically and failover selects the healthy alternative. This would verify resolution of a different case: A branch’s configured SD-WAN SLA uses probe targets reachable only over its primary provider, so the backup is reported degraded even when healthy. It does not show that the reported issue was fixed or that its intended action—Match the correct App-ID or approved application group in the SD-WAN rule.—worked.

Test load allocation stays within revised capacity while priority apps remain stable. This would verify resolution of a different case: A transport change updates one path's assigned bandwidth but SD-WAN policy still selects it for a larger load than the link can carry. It does not show that the reported issue was fixed or that its intended action—Match the correct App-ID or approved application group in the SD-WAN rule.—worked.

An SLA threshold optimized for bulk traffic may not protect real-time media. This mechanism instead explains a separate problem: An SD-WAN branch voice rule uses a generic path quality threshold suitable for large file transfers, allowing jitter that breaks live calls. The current incident requires the more directly applicable cause stated by the correct option.

Aggressive distribution without session awareness can disrupt stateful applications. This mechanism instead explains a separate problem: A company selects symmetric flow distribution for a transactional app but uses indiscriminate per-packet traffic distribution across disparate Internet links. The current incident requires the more directly applicable cause stated by the correct option.

SD-WAN path selection does not automatically repair mismatched NAT identity. This mechanism instead explains a separate problem: During an ISP outage drill, an SD-WAN rule fails over but its source NAT still uses the unavailable provider address and the application's return traffic disappears. The current incident requires the more directly applicable cause stated by the correct option.

Verify probe reachability and target selection on every provider. That safeguard addresses another potential failure: A branch’s configured SD-WAN SLA uses probe targets reachable only over its primary provider, so the backup is reported degraded even when healthy. It is not the most targeted recurring control for the described cause: A quality profile only affects flows that match its referencing SD-WAN policy.

Monitor quality as well as availability for business-critical transports. That safeguard addresses another potential failure: An administrator configures SD-WAN path quality for business collaboration but ignores one-way packet loss on an underlay that appears operational. It is not the most targeted recurring control for the described cause: A quality profile only affects flows that match its referencing SD-WAN policy.

Test loss, latency and jitter independently for each SD-WAN SLA profile. That safeguard addresses another potential failure: A branch health monitor shows packet loss rising above the configured SLA but an engineer expects automatic reroute only when latency and jitter also exceed limits. It is not the most targeted recurring control for the described cause: A quality profile only affects flows that match its referencing SD-WAN policy.

Create a specific SD-WAN policy for the approved payment application and destination, prioritizing the compliant path. That could address a different issue in the same blueprint area: A link management rule selects a low-cost Internet path for payment transactions even though their regulated destination must use the private link. It does not directly correct the given incident, whose decisive mechanism is: Path-quality thresholds can treat any single breached metric as a disqualifier.

Enable appropriate path-health measurement and quality profiles for the protected application. That could address a different issue in the same blueprint area: An SD-WAN deployment monitors only tunnel availability and fails to detect high packet loss while both uplinks remain administratively up. It does not directly correct the given incident, whose decisive mechanism is: Path-quality thresholds can treat any single breached metric as a disqualifier.

Configure appropriate application-specific loss, latency and jitter thresholds in the SD-WAN Path Quality profile. That could address a different issue in the same blueprint area: A branch voice application fails during high jitter on the primary WAN link because its path-quality profile evaluates latency only. It does not directly correct the given incident, whose decisive mechanism is: Path-quality thresholds can treat any single breached metric as a disqualifier.

The primary carries expected load and the LTE link stays within its approved utilization. This would verify resolution of a different case: An SD-WAN traffic distribution policy round-robins traffic over paths of unequal capacity and overloads a small LTE backup link. It does not show that the reported issue was fixed or that its intended action—Review the SD-WAN Path Quality threshold logic and set thresholds that reflect the intended OR-based failure criteria.—worked.

Test traffic chooses the new ISP transport when it satisfies the application policy. This would verify resolution of a different case: After an ISP migration, the SD-WAN policy still points to the retired interface object and traffic cannot select the new healthy transport. It does not show that the reported issue was fixed or that its intended action—Review the SD-WAN Path Quality threshold logic and set thresholds that reflect the intended OR-based failure criteria.—worked.

Payment test flows use the approved private link while ordinary traffic retains its separate routing policy. This would verify resolution of a different case: A link management rule selects a low-cost Internet path for payment transactions even though their regulated destination must use the private link. It does not show that the reported issue was fixed or that its intended action—Review the SD-WAN Path Quality threshold logic and set thresholds that reflect the intended OR-based failure criteria.—worked.

Different application classes require different acceptable loss, jitter and latency thresholds. This mechanism instead explains a separate problem: A branch uses one SD-WAN profile for backup transfers and video calls, resulting in expensive failovers for harmless bulk-traffic delay. The current incident requires the more directly applicable cause stated by the correct option.

Policy references must resolve within applicable management scope and inheritance. This mechanism instead explains a separate problem: An SD-WAN rule refers to a Path Quality profile that was created in a different folder and is unavailable to the branch firewall. The current incident requires the more directly applicable cause stated by the correct option.

Traffic distribution without specific business match conditions can choose an unsuitable egress. This mechanism instead explains a separate problem: A link management rule selects a low-cost Internet path for payment transactions even though their regulated destination must use the private link. The current incident requires the more directly applicable cause stated by the correct option.

Test each SLA dimension against representative critical-app traffic. That safeguard addresses another potential failure: A branch voice application fails during high jitter on the primary WAN link because its path-quality profile evaluates latency only. It is not the most targeted recurring control for the described cause: Path-quality thresholds can treat any single breached metric as a disqualifier.

Alert on measured path-quality violations rather than link state alone. That safeguard addresses another potential failure: An SD-WAN deployment monitors only tunnel availability and fails to detect high packet loss while both uplinks remain administratively up. It is not the most targeted recurring control for the described cause: Path-quality thresholds can treat any single breached metric as a disqualifier.

Maintain application/destination path-policy tests for regulated services. That safeguard addresses another potential failure: A link management rule selects a low-cost Internet path for payment transactions even though their regulated destination must use the private link. It is not the most targeted recurring control for the described cause: Path-quality thresholds can treat any single breached metric as a disqualifier.
