1. 1A new WAN Edge router needs initial authentication and help discovering the other control components. Which component performs that orchestration?

   1. A. SD-WAN Manager
   2. B. SD-WAN Validator
   3. C. SD-WAN Controller
   4. D. Another WAN Edge router

   Answer: B

   Explanation: "This software-based component performs the initial authentication of WAN Edge devices and orchestrates SD-WAN Controller, Manager, and WAN Edge connectivity." The Validator handles the initial join. Manager maintains configuration, Controller distributes control information, and a peer Edge forwards data.

2. 2In Cisco-hosted cloud deployment, who provisions the control components and handles their backups and disaster recovery?

   1. A. The WAN Edge administrator
   2. B. Cisco
   3. C. The MPLS provider
   4. D. The local data center team

   Answer: B

   Explanation: "Cisco takes care of provisioning the control components with certificates and meeting requirements for scale and redundancy. Cisco is responsible for backups/snapshots and disaster recovery." Cisco assumes those cloud-hosted operational duties; the other parties are associated with customer-hosted or transport responsibilities.

3. 3An IOS XE SD-WAN Edge cannot use automated provisioning. Which onboarding method uses a configuration loaded from bootflash or USB?

   1. A. ZTP
   2. B. Bootstrap
   3. C. OMP graceful restart
   4. D. PnP

   Answer: B

   Explanation: "the bootstrap method, which applies to IOS XE SD-WAN routers only, where there is a configuration loaded via bootflash or a USB key" Bootstrap provides local configuration when automation requirements are unmet; ZTP and PnP are automated services.

4. 4An engineer needs to influence overlay routing by matching route and TLOC attributes. Which policy type is appropriate?

   1. A. Localized data policy
   2. B. Centralized control policy
   3. C. Application-aware routing policy
   4. D. WAN interface NAT policy

   Answer: B

   Explanation: "Centralized control policies operate on the routing and TLOC information and allow for customizing routing decisions and determining routing paths through the overlay network." Control policy changes routing information; the alternatives handle packet treatment, SLA path selection, or Internet translation.

5. 5How do SD-WAN devices advertise available network services for service chaining?

   1. A. As OMP service routes
   2. B. As BFD quality samples
   3. C. As Manager user roles
   4. D. As DNS response records

   Answer: A

   Explanation: "advertises available services using OMP service routes with defined service identifiers." OMP service routes identify service availability; the other forms do not advertise chainable services.

6. 6In SD-WAN Manager, which screen shows a selected control component's connections to other control components?

   1. A. Software Repository
   2. B. Control Connections
   3. C. Application Catalog
   4. D. Certificate Signing Request

   Answer: B

   Explanation: "If you select a controller device—a Cisco Catalyst SD-WAN Validator, Cisco SD-WAN Manager, or a Cisco Catalyst SD-WAN Controller, the Control Connections screen opens by default." Manager opens Control Connections for controller devices; the other screens address software, application definitions, or certificates.

7. 7Which Cisco Catalyst SD-WAN component provides the centralized GUI for configuring and monitoring the overlay?

   1. A. SD-WAN Validator
   2. B. WAN Edge router
   3. C. SD-WAN Manager
   4. D. SD-WAN Controller

   Answer: C

   Explanation: "This centralized network management system is software-based and provides a GUI interface to easily monitor, configure, and maintain all Cisco Catalyst SD-WAN devices and their connected links in the underlay and overlay network." Manager supplies the management interface. Validator orchestrates onboarding, Controller handles routing information, and Edge provides site forwarding.

8. 8A Cisco cloud-hosted controller deployment has no Internet reachability from any WAN transport. What prerequisite is missing for control connections?

   1. A. Reachability to the Internet
   2. B. A private MPLS color
   3. C. A second SD-WAN Manager
   4. D. A local certificate server

   Answer: A

   Explanation: "It requires reachability to the Internet in order to connect to the control components." The hosted components need Internet reachability. The other options do not address the documented reachability requirement.

9. 9Which automated onboarding service does an IOS XE SD-WAN router contact for its initial Validator information?

   1. A. The ZTP service at ztp.viptela.com
   2. B. The Manager GUI over NETCONF
   3. C. The PnP service at devicehelper.cisco.com
   4. D. A remote Edge's BFD endpoint

   Answer: C

   Explanation: "For IOS XE SD-WAN routers, it attempts to connect to the PnP server using the hostname devicehelper.cisco.com." IOS XE uses PnP, while vEdge uses ZTP; the other endpoints do not provide this initial discovery.

10. 10A control policy should modify OMP routes before the Controller redistributes them to selected Edge devices. In which direction is it applied from the Controller's perspective?

    1. A. Inbound
    2. B. From-service
    3. C. Outbound
    4. D. From-tunnel

    Answer: C

    Explanation: "Applying a control policy in outbound direction filters or modifies the routes that the Cisco Catalyst SD-WAN Controller redistributes to the Cisco IOS XE Catalyst SD-WAN devices." Outbound applies to Controller-to-Edge advertisements; inbound concerns routes received by the Controller, while the other directions belong to data policy.
