Free Implementing Cisco Service Provider VPN Services (SPVI) Exam 300-515 Exam Practice Test

A network engineer is implementing Layer 3 MPLS VPNs on Cisco IOS/IOS XE PE routers. Which PE-to-CE routing protocol requires a separate routing process to be created for each VRF?

• RIPv2
• OSPF
• BGP
• EIGRP

The network engineering group of a large ISP needs to harden the management plane of its Cisco 9000Series 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?

• icmp ipv6 rate-limit unreachable 1000
• ipv6 rate-limit 1000
• icmp ipv4 rate-limit unreachable 1000
• ipv6 icmp error-interval 50 20

Which mechanism reduces the network flooding caused by host ARP learning behavior?

• ARP suppression
• storm control
• root guard
• BPDU guard

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

• The model is suited for nonredundant configurations.
• The configuration on a newly added site PE is updated automatically.
• Provider routers know the customer network topology.
• The customer specifies the exact site-to-site traffic profile.
• Routing information is exchanged between the customer router and one or a few PEs.

A network architect is troubleshooting the L2TPv3 tunneling security due to the untrusted nature of the underlaying network. Which two L2TPv3 features does the architect deploy to address the ongoing issues? (Choose two.)

• TCP MD5 authentication
• control message hashing
• CHAP authentication
• control message rate limiting
• asymmetric mutual authentication with PSK

An ISP provides a major client MPLS VPN for managed services. The MPLS engineering team needs to use the advanced VPN feature of selective VRF import so that only specific prefixes are present in the required VPNs.Which aspect of this feature must the team consider?

• A route must pass the import route map first and then the route target import filter.
• The routers that are imported in the VRF can be BGP and IGP routes, so other match conditions in the route map, besides communities, can be used.
• The import-map command is applied under the PE interface that connects to the CE router.
• A route is imported into the VRF only when at least one RT that is attached to the route matches one RT that is configured in the VRF and the route is permitted by the import route map.

Which utility can you use to validate an LSP in an MPLS environment?

• uRPF
• MPLS LSP ping
• logging
• RSVP

Which is the primary function of a MPLS L3 VPN route target?

• It imports and exports identified routes into selected VRFs.
• It uniquely identifies NLRIs that have the same numeric value.
• It imports the external routes it identifies into VRFs that support Internet traffic
• It supports QoS by classifying traffic by file type when it applies MPLS EXP bits to each packet.

You are writing the requirements for an MPLS L3VPN environment that uses MP-BGP between PE routers. In this environment, route targets and route distinguishers need to be advertised between the PE routers.Which three operations meet these requirements? (Choose three.)

• mandatory creation of PE-to-PE BGP sessions between the outgoing interface IP addresses
• advertisement of standard communities, enabled on the PE-to-PE BGP neighbors
• creation of PE-to-PE BGP sessions between loopback IP addresses
• full mesh of IBGP sessions
• full mesh of EBGP sessions and partial mesh of IBGP sessions
• advertisement of extended communities, enabled on the PE-to-PE BGP neighbors
