JN0-1361 Online Practice Questions and Answers

You are designing a service provider core network As part of the design, you must ensure that the MPLS

network utilizes the traffic engineering database (TED) for path selection and resiliency. You have chosen

OSPF as the IGP for your design.

In this scenario which statement is correct?

A. You must enable traffic engineering in OSPF to populate the TED.

B. OSPF cannot be used to populate the TED.

C. You must disable traffic engineering in OSPF to use the TED.

D. OSPF populates the TED by default.

A. They must have EBGP configured.

B. They require routes for all remote sites.

C. They must have MPLS configured.

D. They require IP connectivity with the PEs.

D. TACACS

Click the Exhibit button Referring to the network design shown in the exhibit, you must ensure that VPN data between Site1 and Site2 will be earned over a single end-to-end LSP. How would you advertise PE1's loopback address to accomplish this task?

A. over a single MP-IBGP session (L3VPN NLRI) between PE1/PE4

B. over BGP-LU sessions between the PE1/B1. B1/B2 and B2/PE4

C. over a single IBGP session (IPv4 unicast NLRI) between PE VPE4

D. over a single EBGP session (IPv4 unicast NLRI) between PE1/PE4

A. Op scripts

B. JSA scripts

C. REST API

D. XML API

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

A. nonstop bridging

B. nonstop routing

C. graceful restart

D. graceful Routing Engine switchover

Which two statements describe why service providers have migrated to IP/MPLS networks? (Choose two.)

A. MPLS labels enable several logically separated networks to share a common network infrastructure.

B. A single router can be an ingress, egress or transit router for multiple LSPs simultaneously.

C. The MPLS ingress router encapsulates IP packets in an MPLS frame and forwards it to the next router in the path.

D. MPLS virtualization allows a service provider to use statistical multiplexing to maximize resource utilization.

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 )

A. Extend the AS Path length on the prefix advertised to ISP-1 to influence ingress traffic to enter through ISP-1.

B. Use MED and Origin to direct northbound traffic flows out ISP-1

C. Extend the AS Path length on the prefix advertised to ISP-2 to influence ingress traffic to enter through ISP-1.

D. Use Local Preference to direct northbound traffic flows out ISP-1

You work for a service provider that offers L3VPN services to its customers. While designing L3VPN

solutions for customers, you sometimes need to share routes between routing instances as part of the

design.

What are two reasons for sharing routes between routing-instances? (Choose two)

A. so customers can reach the Internet

B. to allow the service provider's OoB network to be reachable by customers

C. so customers can reach the service provider's public cloud infrastructure

D. to support network address translation

You have a customer that operates multiple branch offices and they want a low cost access solution. The WAN must be secure What would satisfy their requirement?

A. an encrypted MPLS service

B. an IPsec VPN using broadband connections

C. a private WAN

D. a managed MPLS service
