1. Which solution allows overlay VNs to communicate with each other in an SD-WAN Architecture?

2. An engineer must design a VPN solution for a company that has multiple branches connecting to a main office.

What are two advantages of using DMVPN instead of IPsec tunnels to accomplish this task? (Choose two.)

3. Which NETCONF operation creates filtering that is specific to the session notifications?

4. An enterprise customer has these requirements:

end-to-end QoS for the business-critical applications and VoIP services based on CoS marking.

flexibility to offer services such as IPv6 and multicast without any reliance on the service provider.

support for full-mesh connectivity at Layer 2.

Which WAN connectivity option meets these requirements?

5. What is a benefit of using VRRPv3 as compared to VRRPv2?

6. A customer is discussing QoS requirements with a network consultant. The customer has specified that end-to-end path verification is a requirement.

Which QoS solution meets this requirement?

7. Which nonproprietary mechanism can be used to automate rendezvous point distribution in a large PIM domain?

8. Which QoS feature responds to network congestion by dropping lower priority packets?

9. Which two BGP features will result in successful route exchanges between eBGP neighbors sharing the same

AS number? (Choose two.)

10. A company is running BGP on a single router, which has two connections to the same ISP.

Which BGP feature ensures traffic is load balanced across the two links to the ISP?

11. Which design consideration should be observed when EIGRP is configured on Data Center switches?

12. Which design consideration must be made when using IPv6 overlay tunnels?

13. When a network is designed using IS-IS protocol, which two circuit types are supported? (Choose two.)

14. What is an advantage of designing an out-of-band network management solution?

15. Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-Access Architecture?

16. Which feature must be incorporated into the campus LAN design to enable Wake on LAN?

17. Which function are fabric intermediate nodes responsible for in an SD-Access Architecture?

18. An organization is designing a detailed QoS plan that limits bandwidth to specific rates.

Which two parameters are supported be the traffic policing feature? (Choose two.)

19. An engineer is looking for a standards-driven YANG model to manage a multivendor network environment.

Which model must the engineer choose?

20. What are two benefits of designing an SD-WAN network fabric with direct Internet access implemented at every site? (Choose two.)

21. Which routes does the overlay management protocol advertise in an SD-WAN overlay?

22. DRAG DROP

Drag and drop the properties from the left onto the protocols they describe on the right.

23. A network solution is being designed for a company that connects to multiple Internet service providers.

Which Cisco proprietary BGP path attribute will influence outbound traffic flow?

24. Refer to the exhibit.

EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the links to R4.

When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?

25. A company is using OSPF between its HQ location and a branch office. HQ is assigned area 0 and the branch office is assigned area 1. The company purchases a second branch office, but due to circuit delays to HQ, it decides to connect the new branch office to the creating branch office as a temporary measure. The new branch office is assigned area 2.

Which OSPF configuration enables all three locations to exchange routes?

26. An engineer must design a multicast network for a financial application. Most of the multicast sources also receive multicast traffic (many-to-many deployment model). To better scale routing tables, the design must not use source trees.

Which multicast protocol satisfies these requirements?

Which multicast protocol meets these requirements?

28. What is one function of the vSmart controller in an SD-WAN deployment?

29. When IPsec VPNs are designed, what is a unique requirement if support for IP Multicast is required?

30. How do endpoints inside an SD-Access network reach resources outside the fabric?

31. When vEdge router redundancy is designed, which FHRP is supported?

32. Which feature is required for graceful restart to recover from a processor failure?

33. DRAG DROP

Drag and drop the characteristics from the left onto the correct telemetry mode on the right.

34. Which method will filter routes between EIGRP neighbors within the same autonomous system?

35. An infrastructure team is concerned about the shared memory utilization of a device, and for this reason, they need to monitor the device state.

Which solution limits impact on the device and provides the required data?

36. What are two valid scaling techniques when an EIGRP network is designed that consists of more than 1000 routers? (Choose two.)

37. Refer to the exhibit.

Which solution decreases the EIGRP convergence time?

38. A router running ISIS is showing high CPU and bandwidth utilization. An engineer discovers that the router is configured as L1/L2 and has L1 and L2 neighbors.

Which step optimizes the design to address the issue?

39. A network engineer must connect two sites across a public network using a secure tunneling technology that supports multicast traffic.

Which technology must be chosen?
