NO.70 Refer to the exhibit.

Refer to the exhibit. The distribution switches serve as the layer 3 boundary. HSRP preemption is enabled. When the primary switch comes back after a failure, traffic is initially dropped. Which solution must be implemented to improve the design?

NO.71 Which technology provides a multichassis IP connection between VSS-enabled switches and downstream devices?

NO.72 A company plans to transition to IPv6. They will link their IPv4 addresses to the lowest significant bits of the new Ipv6 addresses. A network administrator with an employee id: 4264:42:116 is preparing a mapping schema for the new IPv6 addresses. Which address does the 172.16.10.0/24 network translate to?

NO.73 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?

NO.74 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?

NO.75 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?

NO.76 An engineer is creating a design to enable IPv6 to run on an existing IPv4 IS-IS network. The IPv4 and IPv6 topologies will match exactly, and the engineer plans to use the same router levels for each protocol per interface. Which IS-IS design is required?

NO.77 Drag and drop the properties from the left onto the Cisco SD-WAN components that perform them on the right.

NO.78 Refer to the exhibit.

An architect is designing a routing solution for a company. The new design will add a circuit routers C and D to protect against loss of connectivity to 10.0.4.0/24 during a link failure between routers B and D. Which solution must the architect choose?

NO.79 Exhibit:

NO.80 Drag and drop the elements from the left onto the protocols where they are used on the right.

NO.81 Which feature is required for graceful restart to recover from a processor failure?

NO.82 A company must automate a set of complex changes aligned with DR testing in the network. These changes are specific, and the DR playbook will be adjusted in the future. The playbook has diverse routing and switching assets in scope as well as multiple vendor and hardware platforms. A developer will create a thin, web front-end microservice and integrate with an Open daylight controller to push changes to the network.
Which YANG model should be used?

NO.83 An organization plans to deploy multicast across two different autonomous systems. Their solution must allow RPs to:
*discover active sources outside their domain
*use the underlying routing information for connectivity with other RPs
*announce sources joining the group
Which solution supports these requirements?

NO.84 How is end-to-end microsegmentation enforced in a Cisco SD-Access architecture?
