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.)

A.

Implement Enhanced Object Tracking on router R1

B.

use a floating static route

C.

Implement IP SLA on router R1

D.

Implement PBR on router R1

E.

use IP source routing

A network engineer must optimize a campus OSPF deployment Currently each time a type 1 or type 2 LSA is generated within an area, the OSPF process must recompute the entire SPT Which solution improves the recomputation process?

A.

iSPF

B.

BFD

C.

SPF

D.

PRC

A customer has several remote sites connected with their headquarters through microwave links. An engineer must propose a backup WAN solution based on these conditions:

Which backup WAN link type the engineer recommend?

A.

LTE

B.

802.16 WiMAX

C.

Laser link

D.

802.15.1 Bluetooth

An architect is designing a network that will utilize the spanning tree protocol to ensure a loop-free topology. The network will support an engineering environment where it is necessary for end users to connect their own network switches for testing purposes. Which feature should the architect include in the design to ensure the spanning tree topology is not affected by these rogue switches?

A.

BPDU Skew Detection

B.

BPDU guard

C.

loop guard

D.

root guard

Refer to the exhibit A customer wants to adopt a dynamic site-to-site VPN solution to secure communication for VoIP, video, and FTP traffic between the remote branches and the headquarters. The customer also wants the branches to communicate directly, thereby reducing traffic at the headquarters location. The solution must consider that the branch routers are limited in available memory. Which VPN solution meets these requirements?

A.

DMVPN Phase 2 Hub and Spoke design

B.

DMVPN Phase 3 Hub and Spoke design

C.

DMVPN Phase 1 Hub and Spoke design

D.

DMVPN Phase 3 Hierarchical design

Which type of rendezvous point deployment is standards-based and supports dynamic RP discovery?

A.

bootstrap router

B.

Anycast-RP

C.

Auto-RP

D.

static RP

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?

A.

hop-by-hop EVN

B.

multihop MPLS core

C.

multihop IPsec tunneling

D.

hop-by-hop VRF-Lite

Drag and drop the characteristics from the left onto the Yang model they describe on the right.

Select and Place:

AS number? (Choose two.)

A.

advertise-best-external

B.

bestpath as-path ignore

C.

client-to-client reflection

D.

as-override

E.

allow-as-in

Refer to the exhibit.

An architect is designing an EIGRP solution based on these requirements:

Which solution must the architect select?

A.

Maximum-paths 2

B.

Add-paths 2

C.

Metric weights 010100

D.

Variance 2
