Cisco Implementing Cisco Catalyst SD-WAN Solutions Exam Practice Test
The Cisco Implementing Cisco Catalyst SD-WAN Solutions Exam addresses deploying and operating Cisco Catalyst SD-WAN. Its practice questions touch underlay reachability, WAN Edge transport and service interfaces, overlay control connections, route exchange, path preference, IPv6 connectivity, and transport performance monitoring.
Exam overview
About the Cisco Implementing Cisco Catalyst SD-WAN Solutions Exam
SD-WAN operations require separating underlay problems from overlay control and routing issues. A WAN Edge’s transport next hop and interface addressing affect underlay reachability; control connections help establish whether the device is participating in the SD-WAN control plane. Service-side routing decisions include exchanging routes with connected networks, providing a default route, and influencing path selection without changing a destination prefix. Deployment choices also include assigning VLAN interfaces to separate service contexts, using multiple transports, supporting IPv6 clients, and inserting network functions such as firewalls into a traffic path. Operational monitoring involves comparing transport delay and loss over time to distinguish path quality issues. The question bank samples these concepts through configuration and troubleshooting scenarios rather than establishing official exam domains or weighting.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
An administrator wants to confirm that a WAN Edge can reach its transport next hop before investigating overlay behavior. Which test most directly checks that local underlay adjacency?
Show answer
Correct answer: AA source-specific ping to the transport gateway tests local IP connectivity over the intended underlay interface. It helps separate a basic transport adjacency issue from overlay control or policy issues.
A service-side host sends traffic to a remote subnet, but the WAN Edge has no matching route. Which routing mechanism can provide a default route from a service-side routing protocol into the SD-WAN device?
Show answer
Correct answer: AA default route learned from a service-side routing protocol can be redistributed into the device’s routing information so it can forward otherwise unmatched destinations toward the service-side next hop. The other choices do not supply a forwarding route.
A site requires a WAN Edge to perform a function such as firewalling or WAN optimization in the traffic path. Which design approach is appropriate?
Show answer
Correct answer: ATraffic can use a network service only when that service is available in the forwarding path and traffic is directed through it using an appropriate service-insertion or steering design. A transport color or route lifetime alone does not provide service processing.
A branch needs to offer IPv6 connectivity to service-side clients while using the SD-WAN overlay. What must the design account for?
Show answer
Correct answer: AIPv6 service requires compatible addressing and routing across the relevant service-side and overlay portions of the design. Merely changing interface types or disabling route exchange does not provide IPv6 reachability.
When validating an SD-WAN device's operational status, what does a successful control connection indicate?
Show answer
Correct answer: AA successful control connection confirms that the device has established a control-plane session with a controller. It does not by itself prove application-level path preference, LAN host addressing, or loss-free transport performance.
A WAN Edge should prefer one eligible path over another for a route when both are available, without changing the destination prefix. Which route attribute is commonly used to influence path preference in SD-WAN routing?
Show answer
Correct answer: AOMP route preference is a routing attribute that can influence which route or path is selected when alternatives are available. MAC addresses, DHCP lease duration, and application ports do not serve as OMP route-preference attributes.
A site uses a WAN Edge with separate physical interfaces for two service-side VLANs. Which configuration element associates each VLAN interface with its own routed service context?
Show answer
Correct answer: AService VPNs provide separate routed contexts for user or application networks. Assigning service-side interfaces to the appropriate VPN keeps their routing and forwarding logically separated.

Preparation tips
- Practice verifying transport-interface addressing and next-hop reachability before troubleshooting overlay control or route propagation.
- Trace how service-side routes, including a default route, enter the WAN Edge routing context and affect remote-subnet reachability.
- Compare route attributes used for path preference, and distinguish a preference change from a change to the destination prefix.
- Map service-side VLAN interfaces to their routed service contexts; separately consider how IPv6 clients connect through the overlay.
- Review how multiple transports and service insertion affect traffic paths, and interpret delay and loss measurements when comparing transport quality.
