NO.80

Refer to the exhibit. The full EIGRP routing table is advertised throughout the network. Currently, users experience data loss when any one link in the network fails. An architect optimizes the network to reduce the impact when a link fails. Which solution should the architect include in the design?

Run BFD on the inter links between EIGRP neighbors.

Summarize the access layer networks from each access layer switch toward the aggregation layer.

Reduce the default EIGRP hello interval and hold time.

Summarize the access layer networks from the aggregation layer toward the core layer.

NO.81 Refer to the exhibit. AS65533 and AS65530 are announcing a partial Internet routing table as well as their IP subnets. An architect must create a design that ensures AS64512 become a transit AS. Which filtering solution must the architect choose?

Maximum-prefix

No-advertise

Next-hop

No Export

NO.82 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.)

Implement Enhanced Object Tracking on roster R1

use a floating static route

Implement IP SLA on router R1

Implement PBR on router R1

use IP source routing

NO.83 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?

PIM-SM

PIM-SSM

any-source multicast

BIDIR-PIM

NO.84 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?

RSVP

DiffSery

Best Effort

InterServ

NO.85 Which three feature sets are used in Stackwise technology? (Choose three.)

LAN Base

IP Base

WAN Services

IP Services

ARP Base

LAN Agent

NO.86 An engineer must propose a solution for a campus network that includes the capability to create multiple Layer
3 virtual networks. Each network must have its own addressing structure and routing table for data forwarding.
The solution must be scalable to support hundreds of virtual networks and allow simple configuration and management with minimal administrative overhead. Which solution does the engineer recommend?

hop-by-hop EVN

multihop MPLS core

multihop IPsec tunneling

hop-by-hop VRF-Lite

NO.87 Refer to the exhibit. An architect reviews the low-level design of a company’s enterprise network and advises optimizing the STP convergence time. Which functionality must be to Gi1/0/1-10 to follow the architect’s recommendation?

PortFast

root guard

UplinkFast

BPDU guard

NO.88 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?

Increase the hello timers on both HSRP devices

Use the preempt delay feature on the primary HSRP device.

Use the preempt delay feature on the backup HSRP device

Configure a higher mac-refresh interval on both HSRP devices

NO.89 Refer to the exhibit. Where must an architect plan for route summarization for the topology?

from the core toward the aggregation and the access toward the aggregation

from the core toward the aggregation and the aggregation toward the core

from the aggregation toward the access and the access toward the aggregation

from the aggregation toward the core and the aggregation toward the access

NO.90 Refer to the exhibit. An engineer is designing a BGP solution for a client that peers with ISP1 for full Internet connectivity and with ISP2 for direct exchange of routes for several third parties. Which action, when implemented on the edge routers, enables the client network to reach the Internet through ISP1?

Run an eBGP session within different VRFs for each ISP.

Advertise a default route for downstream routers within the client network.

Apply the AS-path prepend feature for ISP2.

Apply route filtering such that the client advertises only routes originated from its own AS.

NO.91 Drag and drop the characteristics from the left onto the telemetry mode they apply to on the right.

NO.92 A network engineer is redesigning a company’s QoS solution. The company is currently using IP Precedence, but the engineer plans to move to DiffServ. It is important that the new solution provide backward compatibility with the current solution. Which technology should the design include?

expedited forwarding

assured forwarding

class selector code points

default per hop behavior

NO.93 An engineer must connect a new remote site to an existing OSPF network. The new site consists of two low-end routers, one for WAN, and one for LAN. There is no demand for traffic to pass through this are a. Which area type does the engineer choose to provide minimal router resources utilization, while still allowing for full connectivity to the rest of the network?

not so stubby

totally not so stubby

totally stubby area

stubby area

NO.94 Drag and drop the properties from the left onto the protocols they describe on the right.
