Refer to the exhibit. Customers report low video quality and delays when having point-to-point telepresence video calls between the two locations. An architect must optimize a design so that traffic follows the same path for egress and ingress traffic flows. Which technique optimizes the design?

A.

Configure route leaking on the router in area 2.

B.

Configure route leaking on the router in area 1.

C.

Configure the high metric on the router in area 4.

D.

Configure route filter on the router in area 4.

A company needs to increase access port capacity on one floor of a building. They want to leverage the existing catalyst access switch. There is no problem with uplink bandwidth capacity. However, no additional uplinks can be added because no ports are available on the distribution switches. Which solution must the company choose to provide additional access ports?

A.

VDC

B.

VSS

C.

Etherchannel

D.

Stackwise

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 is upgrading a company’s main site to include a connection to a second ISP. The company will receive full Internet routing tables from both ISPs via BGP. The engineer must ensure that the company does not become a transit autonomous system. Which solution should be included in this design?

A.

Tag incoming routes from both ISPs with BGP community no-export.

B.

Lower the MED for updates sent to the secondary ISP.

C.

Use a route-map to prevent all prefixes from being advertised to either ISP.

D.

Modify the local-preference for routes incoming from the primary ISP.

Which function does the Cisco SD-Access intermediate node perform?

A.

Act as LISP proxy tunnel router.

B.

Route and transport IP traffic.

C.

Act as an anycast Layer 3 gateway.

D.

Map users to a virtual network.

What is the purpose of service routes in OMP updates?

A.

specify routes toward a centralized orchestration plane

B.

describe underlay transport Information

C.

define the remote management Information

D.

indicate services that are enabled for service insertion

How do IETF. OpenConfig and Cisco nativo YANG models differ when used to configuro the same feature on an infrastructure device?

A.

OpenConfig models are more comprehensive than IETF.

B.

Cisco native models are less comprehensive than OpenConfig.

C.

Cisco native models are less comprehensive than IETF.

D.

IETF models are more comprehensive than OpenConfig.

Refer to the exhibit.

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

* Traffic forwarding should use the best two paths while all links are available

* Single path failure must not impact traffic between branch and HQ

Which solution must the architect select?

A.

Maximum-paths 2

B.

Add-paths 2

C.

Metric weights 010100

D.

Variance 2

Which solution allows overlay VNs to communicate with each other in an SD-WAN Architecture?

A.

External fusion routers can be used to map VNs to VRFs and selectively route traffic between VRFs.

B.

GRE tunneling can be configured between fabric edges to connect one VN to another.

C.

SGTs can be used to permit traffic from one VN to another.

D.

Route leaking can be used on the fabric border nodes to inject routes from one VN to another.

What is one function of the vSmart controller in an SD-WAN deployment?

A.

orchestrates vEdge and cEdge connectivity

B.

responsible for the centralized control plane of the SD-WAN network

C.

provides centralized network management and a GUI to monitor and operate the SD-WAN overlay

D.

provides a data-plane at branch offices to pass traffic through the SD-WAN network
