NEW QUESTION 258

Refer to the exhibit A customer network design team is planning a migration from a legacy TDM-based L2VPN to an MPLS-based L3VPN Migration is planned in a phased approach:
*OSPF backbone Link between HUB A and HUB B sites to be migrated to eBGP
*Spoke A2 and Spoke B1 will be migrated to the L3VPN
Which solution design can be considered to avoid routing loops during backbone link migration?

NEW QUESTION 259
Company XYZ wants to prevent switch loops caused by unidirectional point-to-point link conditions on Rapid PVST+ and MST. Which technology can be used in the design to meet this requirement?

NEW QUESTION 260
Company XYZ has implemented policy-based routing in their network.
Which potential problem must be kept in mind about network reconvergence and PBR?

NEW QUESTION 261
Retef to the exhibit.

This network is running OSPF and EIGRP as the routing protocols Mutual redistribution of the routing protocols has been contoured on the appropriate ASBRs The OSPF network must be designed so that flapping routes m EIGRP domains do not affect the SPF runs within OSPF The design solution must not affect the way EIGRP routes are propagated into the EIGRP domains Which technique accomplishes the requirement?

NEW QUESTION 262
Backups and mirror-copies of data are an essential part of RPO solutions If a business wants to reduce their CAPEX for disaster recovery, which of the following solutions are applicable?

NEW QUESTION 263
An enterprise that runs numerous proprietary applications has major issues with its on-premises server estate hardware, to the point where business-critical functions are compromised. The enterprise accelerates plans to migrate services to the cloud.
Which cloud service should be used if the enterprise wants to avoid hardware issues yet have control of its applications and operating system?

NEW QUESTION 264
Refer to the exhibit.

An architect must design an enterprise WAN that connects the headquarters with 22 branch offices. The number of remote sites is expected to triple in the next three years. The final solution must comply with these requirements:
* Only the loopback address of each of the enterprise CE X and Y routers must be advertised to the interconnecting service provider cloud network.
* The transport layer must carry the VPNv4 label and VPN payload over the MP-BGP control plane.
* The transport layer must not be under service provider control.
Which enterprise WAN transport virtualization technique meets the requirements?

NEW QUESTION 265
You want to split an Ethernet domain in two.
Which parameter must be unique in this design to keep the two domains separated?

NEW QUESTION 266

NEW QUESTION 267
Refer to the exhibit.

There are multiple trees in the Cisco FabricPath All switches in the Layer 2 fabric share the same view of each tree. Which two concepts describe how the multicast traffic is load-balanced across this topology?
(Choose two )

NEW QUESTION 268
A Company wants to design a multicast network with multiple RPs, Their design should be so that source and destination endpoints can connect to the closest RP based on IGP metrics. Which technology best fullfils the design requirements?

NEW QUESTION 269

NEW QUESTION 270
Refer to the exhibit.

The enterprise customer wants to stream one-way video from their head office to eight branch offices using multicast. Their current service provider provides a Layer3 VPN solution and manages the CE routers, but they do not currently support multicast. Which solution quickly allows this multicast traffic to go through while allowing for future scalability?

NEW QUESTION 271
A customer migrates from a traditional Layer 2 data center network into a new SDN-based spine-and-leaf VXLAN EVPN data center within the same location The networks are joined to enable host migration at Layer 2 What is the final migration step after hosts have physically migrated to have traffic flowing through the new network without changing any host configuration?

NEW QUESTION 272

* Provide support for IPv6 customer routes
* Scale up to 250.000 CE devices per customer.
* Provide low operational management to scale customer growth.
* Utilize low-end (inexpensive) routing platforms for CE functionality.
