Free Cisco 300-515 Exam Dumps Questions & Answers

An engineer is investigating an EVPN traffic flow issue. Which type of traffic should the engineer allow in an EVPN Tree Service in order to fix this issue?

• A.multicast from a leaf to another leaf
• B.known unicast from a root to another root
• C.known unicast from a leaf to another leaf
• D.unknown unicast from a leaf to another leaf

Which kind of traffic is supported in an MVPN Extranet?

• A.PIM sparse mode
• B.Bidirectional PIM
• C.PIM dense mode
• D.PIM dense mode with Reverse Path Forwarding

Service provider A is a Tier-2 carrier with an MPLS-enabled network that uses the IS-IS and BGP routing protocols. The service provider is planning to offer a new E-Line service to business customers, and the lead architect has decided to use MP-BGP for the E-Line implementation.
Which action must an engineer take to start the implementation process?

• A.Apply BGP authentication on all PE and P nodes.
• B.Configure the PE nodes to support AFI=25 and SAFI=70.
• C.Upgrade interconnections in the MPLS core to 100Gbps link speeds.
• D.Configure IS-IS multitopology on all PE nodes.

Refer to the exhibit. Router 1 is a P router in the ISP MPLS core.
A connected P router cannot generate an MPLS label for the router 1 loopback0 interface.
Which action resolves this issue?

• A.A static route to null 0 must be added for the loopback interface and then static routes must be redistributed into OSPF
• B.The OSPF network type must be changed on loopback0 to point-to-point
• C.The loopback0 interface must be in OSPF area 0.
• D.The network statement under the routing process must have a wildcard mask of 0 0.0 255.

How do VPNv6 routes propagate between CEs?

• A.The CE uses NAT64 to translate the IPv6 address into a unique IPv4 address, which is sent between sites.
• B.The PE assigns an RD to each VRF and prepends the value to shared IPV6 routes, which allows two or more sites to use a single IP address space.
• C.A DHCP server assigns an IPv4 address and an IPv6 address to each host, and the CE sends traffic from those hosts between sites.
• D.The CE uses Unified MPLS to assign labels to IPV6 traffic only, and then it sends traffic to the PEs using those labels.
