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?

Use EIGRP to establish a neighbor relationship with the main office via

L3VPN MPLS and the IPSEC VPN tunnel.

Use BGP with the multipath feature enabled to force traffic via the primary path when available.

Use static routes tied to an IP SLA to prefer the primary path while a floating static route points to the backup connection.

Use OSPF with a passive-interface command on the backup connection.

NEW QUESTION 101
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?

VPLS

GET VPN

DMVPN

IPsec

NEW QUESTION 102
Refer to the exhibit. An architect must create a stable and scalable EIGRP solution for a customer. The design must:
* conserve bandwidth, memory, and CPU processing
* prevent suboptimal routing
* avoid any unnecessary queries
Which two solutions must the architect select? (Choose two.)

Prefix lists

Stub routing

Distribute lists

Route summarization

NEW QUESTION 103
Which two functions does the control plane node provide in a Cisco SD-Access architecture? (Choose two.)

LISP proxy ETR

host tracking database

policy mapping

map server

endpoint registration

NEW QUESTION 104
Which component is part of the Cisco SD-Access overlay architecture?

border node

spine node

leaf node

Cisco DNA Center

NEW QUESTION 105
Refer to the exhibit.
C0FD9F48 C9ACDC725EA850EC2476EE1E

A network engineer is designing a network for AS100. The design should ensure that all traffic enters AS100 via link 1 unless there is a network failure. In the event of a failure, link 2 should function as the path for incoming traffic. Which solution should the design include?

Modify the next-hop attribute on R3.

Use AS-Path prepending on R3.

Modify the next-hop attribute on R4.

Use AS-Path prepending on R4.

NEW QUESTION 106
Which two functions are provided by the Cisco SD-WAN orchestration plane? (Choose two.)

centralized provisioning

primary authentication point

NAT traversal facilitation

Zero Touch Provisioning

troubleshooting and monitoring

NEW QUESTION 107
A network engineer must design a multicast solution to prevent the spoofing of multicast streams and ensure efficient bandwidth utilization. The network will be merged with another multicast domain in the future, and the merge must require minimum effort. Which two solutions meet the customer requirements? (Choose two.)

PIM-SSM

IGMPv3

IGMPv2

PIM-SM

MSDP

https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipmulti_pim/configuration/xe-16/imc-pim-xe-16-book/imc-msdp-im-pim-sim.html#GUID-4B201DB3-2C27-4F98-977A-A1AE9DC39C21 MSDP is a mechanism to connect multiple PIM-SM domains. The purpose of MSDP is to discover multicast sources in other PIM domains. The main advantage of MSDP is that it reduces the complexity of interconnecting multiple PIM-SM domains by allowing PIM-SM domains to use an interdomain source tree (rather than a common shared tree).

NEW QUESTION 108
Refer to the exhibit.

Refer to the exhibit. An engineer Is designing a multicampus Layer 3 Infrastructure using EIGRP as the routing protocol. The design must provide quick replies to queries In the event of a downlink, prevent unnecessary queries, and ensure that traffic does not unnecessarily transit the access layer. Which two actions must the engineer take for the network design? (Choose two.)

Configure core layer switches as stub routers.

Configure distribution layer switches to summarize routes to the core layer.

Configure access layer switches as stub routers.

Configure access layer and core layer switches as stub routers.

Configure access layer switches to summarize routes to the distribution layer.

NEW QUESTION 109
Refer to the exhibit.

An engineer is designing a routing solution for a customer. The design must ensure that a failure of network
10.1.0.0/24, 10.1.2.0/24, 10.2.1.0/24, or 10.2.3.0/24 does not impact the core. It also requires fast convergence time during any link failover in the core or access networks. Which solution must the engineer select?
