More Details about 300-515 Exam

In taking such a test, candidates hope to pass and gain the CCNP Service Provider certificate. Still, Cisco extends one more certification associated with the same test, which is called the Cisco Certified Specialist – Service Provider VPN Services Implementation. This is a qualification that indicates that you have explored and comprehended all it takes to provide the Cisco SP VPN services. With reference to the CCNP Service Provider, there is a core exam identified as 350-501 that must be passed first. After this step, you move to the concentration part with three exams, where you should pick one test, among which there’s 300-515. Others are 300-510 and 300-535 validations.

NEW QUESTION 28
What is the primary function of a VRF on a router?

 It enables the router to support multiple separate routing tables, which allows the device to handle overlapping IP addresses.

 It enables a router to run BGP and a distance vector routing protocol at the same time, which allows it to serve as a VPN endpoint between remote sites.

 It enables a router to configure VLANs locally, which provides segregation between networks.

 It enables the router to provide faster switching through the network by using labels to identify the input and output interfaces for neighbor routers.

NEW QUESTION 29
What do EVPN single-active and all-active have in common?

 They are default gateway redundancy options.

 They are multihoming mechanisms used for CE devices.

 They are used to provide single connection from a CE device to a service provider.

 They are both roles that a designated router can take when MPLS is used with EVPN.

 The loopback0 interface must be in OSPF area 0.

 The network statement under the routing process must have a wildcard mask of 0 0.0 255.

 The OSPF network type must be changed on loopback0 to point-to-point

 A static route to null 0 must be added for the loopback interface and then static routes must be redistributed into OSPF

NEW QUESTION 32
Refer to the exhibit.

PE1 and PE2 are exchanging VPNv4 routes for CE1 and CE2, and PE3 contains the default route to the internet. If the three devices are operating normally, which two conclusions describe this configuration?
(Choose two.)

 The CE1 and CE2 VRFs can exchange routes only between their respective VRFs on PE1 and PE2.

 All three routers must be running a distance-vector routing protocol.

 All three routers must be running MP-BGP.

 The CE1 and CE2 VRFs can access the default route provided by the Internet VRF.

 Only the CE2 VRF can access the default route provided by the Internet VRF.

NEW QUESTION 33
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?

 Configure static routing on the CE router.

 Configure the address-family ipv4 labeled-unicast command under the neighbor configuration of the CE router for the PE.

NEW QUESTION 35
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?

 known unicast from a leaf to another leaf

 unknown unicast from a leaf to another leaf

 multicast from a leaf to another leaf

 known unicast from a root to another root

NEW QUESTION 36
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.
