QUESTION 98
An engineer must design a QoS solution for a customer that is connected to an ISP over a 1Gbps link with a 100Mbps CIR. The ISP aggressively drops all traffic received over which is causing numerous TCP retransmissions. The customer is not using any RTP applications but wants to maximize bandwidth usage up to the CIR. Which QoS solution engineer choose?

QUESTION 99
Refer to the exhibit.

The failover time of ISP-2 is significantly shorter than ISP-1 when an interface on the ISP router toward the campus network fails. Which solution minimizes the downtime to the sub-second?

QUESTION 100
Refer to the exhibit.

A network engineer must improve the current IS-IS environment. The Catalyst switch is equipped with dual supervisors. Each time a stateful switchover occurs, the network experiences unnecessary route recomputation. Which solution addresses this issue if the upstream router does not understand graceful restart messaging?

QUESTION 101
Refer to the exhibit.

Refer to the exhibit. An engineer must design an automatic failover solution. The solution should allow HSRP to detect a WAN 1 failure and initiate an automatic failover, making router R2 the active HSRP router. Which two solutions should the engineer choose? (Choose two.)

QUESTION 102
An engineer must peer with an ISP for internet connectivity using BGP, initially, the engineer wants to receive only specific prefixes from the ISP and a default route. However, the solution must provide the flexibility to add prefixes in the future at short notice. The ISP has a two-week change process in place. Which route filtering solution must the engineer employ?

QUESTION 103
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?

QUESTION 104
An engineer is designing a BGP network for a large customer. To permit efficient scaling, the BGP domain is split into clusters. Which peering solution should be used between the route reflectors in different clusters for the BGP routes to be propagated appropriately?

QUESTION 105
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.)

QUESTION 106
An engineer is designing a multicast network for a company specializing in VoD content. Receivers are across the Internet, and for performance reasons, the multicast framework close to the receivers within each AS. For high availability, if the sources in one AS are no longer available, the receivers of that AS must be able to receive the VoD content from sources in another AS. Which feature must the design include?

QUESTION 107
In an SD-WAN architecture, which methods are used to bootstrap a vEdge router?

QUESTION 108
Drag and drop the properties from the left onto the protocols they describe on the right.

QUESTION 109
Which two border nodes are available in the Cisco SD-Access architecture? (Choose two.)

QUESTION 110
Drag and drop the characteristics from the left onto the YANG modules they describe on the right. Not all options are used.

QUESTION 111
A customer’s current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals:
reduce the impact of topology changes
reduce the time spent on network administration
reduce manual configuration errors
Which two solutions should the architect include in the new design? (Choose two.)

QUESTION 112
What are two benefits of designing an SD-WAN network fabric with direct Internet access implemented at every site? (Choose two.)
