Which topology supports these requirements?

9. A company with multiple service providers wants to speed up BGP convergence time in the event a failure occurs with their primary link.

Which approach achieves this goal and does not impact router CPU utilization?

10. An engineer is working with NETCONF and Cisco NX-OS based devices. The engineer needs a YANG model that supports a specific feature relevant only to Cisco NX-OS.

Which model must the engineer choose?

11. What is the purpose of an edge node in an SD-Access network fabric?

13. When designing interdomain multicast, which two protocols are deployed to achieve communication between multicast sources and receivers? (Choose two.)

14. A branch office has a primary L3VPN MPLS connection back to the main office and an IPSEC VPN tunnel that serves as backup.

Which design ensures that data is sent over the backup connection only if the primary MPLS circuit is down?

15. Company A recently acquired another company. Users of the newly acquired company must be able to access a server that exists on Company A’s network, both companies use overlapping IP address ranges.

Which action conserves IP address space and provides access to the server?

16. In an SD-WAN architecture, which methods are used to bootstrap a vEdge router?

17. An engineer must propose a QoS architecture model that allows an application to inform the network of its traffic profile and to request a particular type of service to support its bandwidth and delay requirements. The application requires consistent and dedicated bandwidth end to end.

Which QoS architecture model meets these requirements?

18. Which two statements about VRRP advertisements are true? (Choose two.)

19. Which two statements about VRRP object tracking are true? (Choose two)

20. Which common issue causes intermittent DMVPN tunnel flaps?

21. Which two best practices must be followed when designing an out-of-band management network? (Choose two.)

22. A network administrator is troubleshooting a DMVPN setup between the hub and the spoke.

Which action should the administrator take before troubleshooting the IPsec configuration?

23. Which two options can you use to configure an EIGRP stub router? (Choose two)

24. At which layer does Cisco Express Forwarding use adjacency tables to populate addressing information?

25. DRAG DROP

An engineer must design an addressing plan for a small business using a single /24 network. Each department must have its own subnet.

Drag and drop the subnets from the left onto the departments requirements that they fulfill on the right. Not all options are used.

26. A customer has several remote sites connected with their headquarters through microwave links.

An engineer must propose a backup WAN solution based on these conditions:

Which backup WAN link type the engineer recommend?

27. How is internet access provided to a WAN edge router that is connected to a MPLS transport link?

28. DRAG DROP

Drag and drop the characteristics from the left onto the telemetry mode they apply to on the right.

29. A network engineer must segregate three interconnected campus networks using IS-IS routing. A two-layer hierarchy must be used to support large routing domains and to avoid more specific routes from each campus network being advertised to other campus network routers automatically.

Which two actions does the engineer take to accomplish this segregation? (Choose two.)

30. Refer to the exhibit.

All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs.

To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)

31. Which component of Cisco SD-Access integrates with Cisco DNA Center to perform policy segmentation and enforcement through the use of security group access control lists and security group tags?

32. What is the role of a control-plane node in a Cisco SD-Access architecture?

33. How is end-to-end micro segmentation enforced in a Cisco SD-Access architecture?

VLANs are used to segment traffic at Layer 2.

5-tuples and ACLs are used to permit or deny traffic.

SGTs and SGTACLs are used to control access to various resources.

VRFs are used to segment traffic at Layer 3.

34. Which two border nodes are available in the Cisco SD-Access architecture? (Choose two.)

35. An engineer is upgrading a company’s main site to include a connection to a second ISP. The company will receive full Internet routing tables from both ISPs via BGP. The engineer must ensure that the company does not become a transit autonomous system.

Which solution should be included in this design?

36. DRAG DROP

Drag and drop the properties from the left onto the Cisco SD-WAN components that perform them on the right.

37. Which two functions are provided by the Cisco SD-WAN orchestration plane? (Choose two.)

38. A large chain of stores currently uses MPLS-based T1 lines to connect their stores to their data center.

An architect must design a new solution to improve availability and reduce costs while keeping these considerations in mind:

» The company uses multicast to deliver training to the stores.

» The company uses dynamic routing protocols and has implemented QoS.

» To simplify deployments, tunnels should be created dynamically on the hub when additional stores open.

Which solution should be included in this design?
