Free Cisco 300-510 Practice Test & Real Exam Questions

Refer to the exhibit. The network is configured for multicast using PIM-SM. A server connected to R3 streams multicast data to hosts located on R4. To support expected growth in the network, the network engineer with an employee ID: 123456789 has decided to implement Auto-RP to dynamically assign a rendezvous point (RP). Which action must be taken?

A CRS router that runs Cisco IOS XR has dual routing processors installed.
Which solution should be implemented to prevent OSPF adjacency flapping if the primary routing processor fails?

Refer to the exhibit. While configuring router 2 with all the default values, a network engineer cannot see any route received in router 1. How should the engineer solve the issue?

What is the difference between basic IS-IS and OSPF packet types?

Refer to me exhibit. Refer to the exhibit. A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501. The engineer wants to block all the routes coming from ASN 64502 but allow all the others. For that purpose, the following AS Path prefix list is being used:
(config)#ip as-path access-list 10 deny _64502$
What must be fixed to achieve this result?

Refer to the exhibit. Company A established BGP sessions with several ISPs. A network engineer at the company must filter out all traffic except for routes that transit AS 152. The engineer configured the filtering policy "permit _152$_(_[0-9])" on R1, but after applying the configuration, the engineer notices that other routes are still visible. Which action resolves the issue?

Which cost is the default when redistributing routes from BGP to OSPF?

Refer to the exhibit. After a recent network implementation project, customer A is performing stress testing to verify network redundancy at the branch office connected to R4. When the link from R2 is shut down as shown, the SLA tracking object fails and the cost of the link between R2 and R4 increases to 100. However, a traceroute operation from a PC in the branch office shows that traffic to HQ is still routed via R2. Which solution corrects the problem and optimizes traffic flow via R3 without creating operational overhead?

Refer to the exhibit. A network operator is working to filter routes from being advertised that are covered under an aggregate announcement.
The receiving router of the aggregate announcement block is still getting some of the more specific routes plus the aggregate.
Which configuration change ensures that only the aggregate is announced now and in the future if other networks are to be added?

What are two features of dual-stack? (Choose two.)

Refer to the exhibit. After maintenance to activate BGP neighbors connecting a new data center attached to R1, L3VPN customers attached to OSPF domain 100 lost connectivity to services in OSPF 200 and OSPF 300. However, Unified MPLS services within OSPF 100 remain reachable.
Which action must the network engineer take to resolve the outage?

Refer to the exhibit. CE1 and CE2 are iBGP neighbors in AS 65516. All traffic that exits AS 65516 must use the link from CE1 to PE1. CE1 is advertising a higher local preference to CE2, but traffic from CE2 still prefers the PE2 link. Which action corrects the problem?

Refer to the exhibit. The initial BGP configuration of the network is complete, and all the routers have established BGP neighborship. The engineer configured Router 2 with additional BGP paths to install and advertise more paths to Router 1 and Router 3. Which configuration must the engineer apply to Router 1 and Router 3 so that they will use and install all additional paths?

Refer to the exhibit. Which router does R1 install as an alternate next hop when trying to reach R3 if LFA is enabled?
