QUESTION 29
Exhibit.

You are asked to ensure that most traffic that traverses your network is load balanced over all of the equal cost links between the routers in your network. However, you must also ensure that traffic from ISP A that is destined for ISP D must traverse the R1-R2-R3-R4-R5 path.

QUESTION 34
You are asked to design a DDoS prevention system to help mitigate denial-of-service attacks that target your customers. The management group wants to know the effect remote triggered black holes may have on current network operations if they are implemented as a solution.
Which three statements are correct in this scenario? (Choose three)

QUESTION 35
Your client asked you to design a solution with the requirements shown below.
– Have better traffic engineering for applications across an existing MPLS core.
– Support both IPv4 and IPv6 traffic
– Work with an MX Series core.
– Work with a North Star Controller
– Work with existing IGP (ISIS)
Which feature would you recommend be implemented in this solution?

QUESTION 36
You are designing several MPLS virtual routing and forwarding (VRF) instances on all provider edge (PE) routers. Routes within each VRF should be exchanged between all PE routers provisioned for that VRF.
For each VRF routing instance which two attributes must match on all related PE routers? (Choose two )

QUESTION 37
Your customer is deploying a data center with redundant connections for WAN services through ISP-1 and ISP-2. Your customer has decided to deploy an active/passive Internet connection uplink model and pay-per-use for a passive connection associated with ISP-2. The customer wants to ensure limited use of the connection through ISP-2.
Which two actions would you perform to meet the objective? (Choose two )

QUESTION 38
Which two statements about BFD are correct? (Choose two)

QUESTION 39
In your class-of-services design, you are using a multified classifier on your WAN edge devices to ensure that traffic is properly classified entering your network. You are asked to ensure that all packets traversing your core will be handled in the same manner without using firewall filters.
Given this scenario, which statement is correct?

QUESTION 40
Exhibit.

You work for service provider B that wants to implement a hot potato routing policy on the network so that router C uses link C-A to reach service provider A’s advertised routes and router D uses link D-B to reach Service Provider A’s advertised routes Currently traffic from router C is traversing the core to exit the network on router B.
Referring to the exhibit, what are two design actions that would satisfy the requirements? (Choose two.)

QUESTION 41
You are asked to provide a design proposal for a service provider network that will need to support both IPv4 and IPv6 traffic across your IPv4 core. You do not want to change the core design.
In this scenario, what are two solutions that you would implement at the peering edge? (Choose two.)

QUESTION 42
Exhibit.

You want to design a VPN service that will allow your enterprise the ability to span their VLANs between the four sites shown in the exhibit, while allowing point-to-multipoint connectivity.
Which two MPLS VPN technologies allow this type of functionality (Choose two.)

QUESTION 43
You are working on a multi-Data Center interconnect (DCI) solution. Your WAN is based upon a multipoint MPLS Layer 3 VPN. This design must provide Layer 2 connectivity between the data centers across your WAN.
Which technology would satisfy the requirement?

QUESTION 44
You are asked to provide a design proposal for a services provider’s core network. The network consists of both IPv2 and IPv4 addresses and must scale up to 50 core routing devices. As part of your design, you must in redundancy and ensure that future network expansion is easily incorporated.
In this scenario, which statement is correct regarding the BGP design?

QUESTION 45
Exhibit.

Within ISP E, R1 is load-balancing traffic destined to ISP D over the R1-R2-R5 and R1-R4-R5 paths. At some point, a link degradation event occurs in the network as shown in the exhibit. You want R1 to rapidly learn of the path failure.

QUESTION 46
You want to implement Source Packet Routing in Networking (SPRING) in your network core using MPLS as the data plane for traffic engineering purposes.
In this scenario what are two protocols that would be used to distribute the segment IDs? (Choose two )

QUESTION 47
A customer requests that you design their Layer 3 VPN solution so that all site-to-site traffic goes through a central site, in a hub-and-spoke fashion You must choose between using one or two interfaces on the hub WAN link.
In this scenario, which solution would you use?

QUESTION 48
You are creating an MPLS design proposal for a customer that requires traffic engineering features through their core MPLS network. The customer has edge routers that only support LDP signaling.
Which two features would you propose using in this scenario? (Choose two)

QUESTION 49
Which technology allows a router to continue to forward packets even if the routing protocol adjacencies go down?

QUESTION 50
As a service provider network architect, you are working with a potential customer who wants to replace their WAN, consisting of two data centers, one HQ, and 76 branch offices Due to application latency requirements between branch offices, the customer insists that all traffic must take the most optimal path through the service provider network.
