Cisco 300-515 Test Engine Dumps Training With 72 Questions

300-515 Questions Pass on Your First Attempt Dumps for CCNP Service Provider Certified

By finalizing training in any of the three formats, you will gain 40 CE credits that will count during recertification. Again, doing so prepares you to receive success in the exam. Some other benefits of passing through the training include the reinforcement of knowledge about fundamental concepts of MPLS VPN, including its pros as well as classification. Also, one gains insights into the configuration of optional paths in reference to traffic so that there is no network congestion. Therefore, if this is how you wish to prepare for the official exam and get ready for your upcoming job tasks, you need to enroll for official training. The specialists specifically targeted by this prep plan for exam 300-515 include network architects, network engineers, network managers, network administrators, network supervisors, network designers, and more. They will be garnering the comprehension of the techniques for executing, configuring, monitoring, and supporting solutions for SP VPN that are based on backbones for MPLS. Even as you consider registering for such a course, ensure you are aware of the prerequisites. They include having SP knowledge at the professional standard, which is equivalent to the content that you get from courses such as:

Deploying Cisco SP Network Routing (SPROUTE);
Building Cisco SP Next-Generation Networks Part 2 (SPNGN2) v1.2.
Building Cisco SP Next-Generation Networks Part 1 (SPNGN1) v1.2;

PIM dense mode with Reverse Path Forwarding

PIM dense mode

PIM sparse mode

Bidirectional PIM

NO.48 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.
