Cisco 300-515 Actual Free Exam Questions & Community Discussion

Which two functions describe CsC architecture on the network? (Choose two.)

In MPLS Layer 3 VPN implementations, which mechanism is used to control which routes are imported to a VRF?

Refer to the exhibit. An engineer working for a service provider with an employee ID: 4985:13:314 is troubleshooting an ongoing network outage on an E-Line Services Network with L2VPN single- segment pseudowires. The verification confirmed that the Layer 2 configuration is correct and the physical connection between the devices is working normally. Which additional command sequence resolves the issue?

SIMULATION 1
Guidelines
This is a lab item in which tasks will be performed on virtual devices.
Refer to the Tasks tab to view the tasks for this lab item

Refer to the Topology tab to access the device console(s) and perform the tasks.

Console access is available for all required devices by clicking the device icon or using the

tab(s) above the console window.
All necessary pre-configurations have been applied.

Do not remove any existing configurations from the devices, only those necessary to make the

appropriate changes required to fulfill the listed tasks.
Do not change the enable password or hostname for any device.

Save your configurations to NVRAM before moving to the next item.

Tasks
CE1 and CE2 are customer premise equipment of the same customer that communicates with each other over L2VPN provider infrastructure comprising Provide Edge PE1, PE2, and P core routers.
Configure the PE routers to choose the configured Loopback 0 as its LDP identifier persistently.

Troubleshoot the PEs to establish a complete MPLS LSP path between them.

Troubleshoot and modify PE2 to ensure the configured L2VPN VC is up and passing traffic.

Initial configuration with IPv6 addressing has been completed. The candidate must not make any changes to the configurations except to fulfill the tasks listed above. Apply the solution with the minimum config.

The network engineering group of a large ISP needs to harden the management plane of its Cisco 9000 Series ASRs.
While addressing IPv6 ICMP issues, they realized they have to limit the rate at which IPv6 ICMP error messages are sent out on the network.
Which command do they need to apply?

Which method can be used to discover targeted LDP neighbors dynamically when configuring VPLS between PE routers?

Refer to the exhibit. The CE router has established a BGP peering with the PE router, and the CE will use the core infrastructure of the PE as a backbone carrier to support CSC.
Which additional task can you perform to complete the configuration?

A network architect is planning an inter-AS and intra-AS infrastructure for an organization with multiple locations that requires internet access for all sites and for data to be available between sites. Which consideration should be part of the design?

Which two are characteristics of using a non-MPLS peer-to-peer model over a traditional overlay model? (Choose two.)

Refer to the exhibit. VLAN 10 is experiencing congestion on the link to ISP 1. The network architect asked an engineer to update the configuration on RA so that VLAN 10 traffic travels via ISP 2 without affecting traffic from VLAN 20.
Which action meets this requirement?

Refer to the exhibit. A small company contracted to receive centralized training services from a larger organization. The services are provided via an extranet that is distributed between the organizations across an ISP connection using multicast. Security must be high to ensure that data is not compromised. Which action must be taken at the ISP to implement the required services?

Which two statements about MPLS L3 VPN RDs are true? (Choose two.)

How do EFPs distinguish flows?

Refer to the exhibit. A large regional company has two primary offices in different cities, connected via a service provider that provides Layer 3 connectivity between the two sites.
Although the two company offices are physically separated, traffic from site B to the Internet uses the PE1 internet connection. The service provider is running OSPF in its core, with the loopback 0 IP address used as the OSPF and BGP router IDs. After the most recent service provider maintenance window, during which P3 was rebooted, the connection between CE1 and CE2 failed to come up. Which action must network engineers take to resolve the issue?

Refer to the exhibit. While provisioning a new BGP session between the PE and CE router, you issue the as-override command. Which statement describes modification of the prefix before being sent to the CE router (10.10.10.1)?
