How many Troubleshooting Scenario Questions questions are on this page?

This page has 13 Troubleshooting Scenario Questions scenario questions for the SD-WAN-Engineer exam, each with detailed explanations and wrong-answer analysis.

How should I approach SD-WAN-Engineer scenario questions?

Read the full scenario before looking at the answer options. Identify the constraint or requirement in the scenario, then eliminate options that are generally true but wrong for this specific case. Scenario questions reward careful reading over pattern matching.

How to approach troubleshooting scenario questions

These questions describe a network symptom and ask you to identify the root cause or the correct fix. They appear across all certification exams and reward systematic thinking over memorisation. The best candidates follow a consistent troubleshooting framework even under time pressure.

Quick answer

Troubleshooting Scenario Questions questions test whether you can apply the concept in context, not just recognise a definition.

How the topic appears in realistic exam-style scenarios.

Which detail in the question changes the correct answer.

How to eliminate plausible but wrong options.

How to connect the question back to the wider exam objective.

Practice scenarios

Question 1mediummultiple choice

Full question →

You are troubleshooting a performance issue where traffic is not taking the preferred path. Which tool in the Controller helps you visualize the path taken?

A
Interface counters
Why wrong: Counters do not reveal path selection logic.
B
Flow Monitoring
Flow monitoring provides deep visibility into the path and policy enforcement.
C
System Logs
Why wrong: Logs do not visualize path metrics.
D
Packet Capture
Why wrong: Too granular; flow monitoring is better for path analysis.

Question 2mediummultiple choice

Full question →

If a device is stuck in 'In-Progress' during a template push, what is the first troubleshooting step?

A
Check the Device Tasks in vManage to view the specific error log.
Device Tasks provide the most accurate status of a deployment operation.
B
Reboot the vManage server.
Why wrong: Rebooting vManage is overkill and disruptive for other sites.
C
Perform a factory reset on the device.
Why wrong: A factory reset is a destructive action that should not be the first step.
D
Change the vBond address.
Why wrong: The vBond address is only for initial orchestration.

Question 3hardmultiple choice

Read the full VPN explanation →

When troubleshooting a site-to-site VPN issue between two ION devices, which status should you check first?

A
NTP synchronization
Why wrong: While important, it is rarely the cause of a tunnel being down compared to configuration issues.
B
ISP routing table
Why wrong: Too low level; check the overlay first.
C
BIOS settings
Why wrong: BIOS is irrelevant to VPN status.
D
VPN Tunnel Status in the Orchestrator
The orchestrator provides the status of the overlay tunnels between nodes.

Question 4hardmulti select

Full question →

Which THREE areas of configuration should you verify if a site cannot reach the local LAN gateway?

A
Application security policy
Why wrong: Local LAN traffic typically bypasses these.
B
Interface IP/Mask
Must be on the same subnet as the gateway.
C
VLAN tagging configuration
Incorrect tagging prevents L2 communication.
D
Controller tunnel status
Why wrong: Only affects WAN connectivity.
E
ARP table status
Failure to resolve the gateway MAC address is a common symptom.

Question 5mediummultiple choice

Full question →

A branch loses connectivity to the internet, but local LAN traffic is fine. What should you troubleshoot first?

A
ISP connection and WAN interface
The WAN interface is the demarcation point for internet access.
B
Device power supply
Why wrong: The device is clearly on.
C
DHCP server settings
Why wrong: Clients have IPs since local traffic works.
D
Core Switch configuration
Why wrong: LAN traffic is working, so the switch is fine.

Question 6hardmultiple choice

Full question →

When troubleshooting a persistent 'Service Connection Down' status, which log type is most relevant?

A
System health logs
Why wrong: These are for hardware status.
B
User activity logs
Why wrong: These are for user traffic, not control plane status.
C
Application performance logs
Why wrong: These are for traffic quality monitoring.
D
Service Connection event logs
These logs specifically track the lifecycle of the tunnel.

Question 7mediummultiple choice

Study the full QoS explanation →

When troubleshooting QoS, what does a high 'drop' count in the interface statistics imply?

A
Hardware failure
Why wrong: Hardware failures usually cause link loss.
B
Security policy blocking
Why wrong: Security drops show up in security logs.
C
Interface congestion
Drops occur when traffic exceeds the shaping rate.
D
The ISP is down
Why wrong: Down links would show 'down' status, not drops.

Question 8hardmulti select

Full question →

Which THREE methods can be used to troubleshoot application identification issues?

A
Perform a Packet Capture
Deep inspection confirms the application signature.
B
Review application signatures in the orchestrator
Ensures the latest signatures are active.
C
Check the BGP table
Why wrong: Unrelated to app identification.
D
Reboot the router
Why wrong: Unlikely to resolve identification logic issues.
E
Check the Flow Monitor
Shows the identified application for sessions.

Question 9mediummultiple choice

Study the full SD-WAN breakdown →

An engineer is troubleshooting a scenario where users at a branch office cannot access SaaS applications via Prisma Access. The SD-WAN path is active, but the traffic is not reaching the Cloud SWG. What is the most likely cause related to the Unified SASE policy?

A
The ION device is missing the latest firmware
Why wrong: Firmware does not typically cause routing policy failures of this nature.
B
The Cloud Identity Engine is not reachable
Why wrong: This would affect authentication but not initial routing to the gateway.
C
The Security Policy rule for the branch traffic is set to 'Direct to Internet' instead of 'Service Connection'
Traffic must be explicitly routed to the Service Connection to reach Prisma Access.
D
The WAN port is set to DHCP
Why wrong: DHCP is a valid configuration for WAN connectivity.

Question 10hardmultiple choice

Full question →

You are troubleshooting a performance issue where traffic is not taking the expected 'optimal' path. Which tool should you examine first to see the PFR path selection decision?

A
System Health Logs
Why wrong: System health covers hardware status, not policy decisions.
B
Controller Audit Logs
Why wrong: Audit logs track configuration changes, not traffic decisions.
C
Packet Capture
Why wrong: PCAP is for data analysis, not viewing policy decision history.
D
Application Performance Logs
These logs detail the path selection engine's rationale.

Question 11hardmulti select

Full question →

Which THREE logs or reports should be reviewed to troubleshoot a security policy drop?

A
Security Logs
Explicitly records security-related drops.
B
Session Monitor
Provides real-time view of session drops.
C
Flow Reports
Shows the flow status and disposition.
D
Hardware Inventory
Why wrong: Hardware related.
E
BGP Neighbors
Why wrong: Routing related.

Question 12hardmultiple choice

Full question →

If a user is incorrectly identified in a SASE security log, which part of the Unified SASE architecture should be investigated first?

A
The ION device WAN interface
Why wrong: The interface doesn't know about user identities.
B
The DNS settings
Why wrong: DNS does not determine user identity.
C
The Cloud Identity Engine
CIE is the source of user identity information.
D
The Prisma SD-WAN Controller
Why wrong: The controller routes traffic but doesn't map users.

Question 13hardmulti select

Full question →

Which THREE parameters are essential when troubleshooting a Service Connection tunnel status?

A
Tunnel interface MTU settings
MTU mismatches cause tunnel failures.
B
The number of users currently active
Why wrong: Not related to tunnel status.
C
Public IP connectivity from the ION WAN port
The tunnel needs internet reachability.
D
IKE phase 1 and 2 policy settings
Incompatible crypto settings prevent tunnel establishment.
E
The serial number of the ION device
Why wrong: Used for registration, not tunnel troubleshooting.
