Which model must the engineer choose?

20. 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?

21. Refer to the exhibit.

An engineer is designing an OSPF network for a client. Requirements dictate that the routers in Area 1 should receive all routes belonging to the network, including EIGRP, except the ones originated in the RIP domain.

Which action should the engineer take?

22. A customer with an IPv4 only network topology wants to enable IPv6 connectivity while preserving the IPv4 topology services. The customer plans to migrate IPv4 services to the IPv6 topology, then decommission the IPv4 topology.

Which topology supports these requirements?

23. DRAG DROP

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

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

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

26. Refer to the exhibit.

Which two solutions maximize the use of the links between the core and distribution layers? (Choose two.)

27. Refer to the exhibit.

Area 10 is a regular OSPF area and networks 10.1.1.0/24 and 172.16.1.0/24 are internal.

Which design provides optimal routing between both networks when the link between routers C and E fails?

28. Which common issue causes intermittent DMVPN tunnel flaps?

29. How is sub-second failure of a transport link detected in a Cisco SD-WAN network?

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

31. An engineer is working for a large cable TV provider that requires multiple sources streaming video on

different channels using multicast with no rendezvous point.

Which multicast protocol meets these requirements?

32. Which control-plane technology allows the same subnet to exist across multiple network locations?

33. When a first hop redundancy solution is designed, which protocol ensures that load balancing occurs over multiple routers using a single virtual IP address and multiple virtual MAC addresses?

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

35. An engineer is tasked with designing a dual BGP peering solution with a service provider.

The design must meet these conditions:

• The routers will not learn any prefix with a subnet mask greater than /24.

• The routers will determine the routes to include in the routing table based on the length of the mask alone.

• The routers will make this selection regardless of the service provider configuration.

Which solution should the engineer include in the design?

36. 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?

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

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

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

40. 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?

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

The solution must include redundant WAN links, but the customer has a limited budget and wants the ability to increase the link speed easily in the future. QoS will not on the branch routers so there is no need for consistent end-to-end QoS.

Which solution does the architect propose?
