300-420 Exam Dumps - Designing Cisco Enterprise Networks (ENSLD)

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?

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?

An engineer is designing a Layer 3 campus network running EIGRP between the core, aggregation, and access layers. The access layer switches will be connected to the aggregation layer using Layer 3 copper connections. The engineer wants to improve convergence time for access layer switch failures. Which technique must the design include?

Which design achieves SD-WAN control plane redundancy?

An engineer must design a scalable QoS architecture that allows the separation of the traffic into classes on predefined business requirements. The design must also utilize the differentiated services code points as the QoS priority descriptor value and support at least 10 levels of classification. Which QoS technology should the engineer include in the design?

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?

Refer to the exhibit.

Which solution decreases the EIGRP convergence time?

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?
