Cisco 300-510 Online Questions & Answers

• Question 41:

  Refer to the exhibit.

  

  An administrator is troubleshooting network issues on a customer's network PE1 cannot form an LDP relationship with PE2 using LDP ID 192 168.1.1. Due to this connectivity issue, the customer's routes behind both PE routers cannot be exchanged. Which action must the administrator take to correct the problem?

  A. Configure PE2 to automatically select its own LDP router ID with 192.168.1.1.
  B. Create a targeted LDP session on PE2 to override the missing routing table entry on PE1.
  C. Configure PE1 with a static route to 192.168.1.1.
  D. Enable LDP session protection on the link that P1 uses as the next hop to PE2.
  C. Configure PE1 with a static route to 192.168.1.1.

• Question 42:

  DRAG DROP

  Drag and drop the characteristics from the left onto the corresponding routing protocols on the right.

  Select and Place:

  

  

• Question 43:

  Refer to the exhibit.

  

  ISP_A in AS 635 has four BGP neighbors connected one by one, starting with AS 12. R1 has been configured with bgp deterministic-med and bgp additional-paths install to influence egress traffic. After a recent reload of R10, all traffic was automatically rerouted via AS 87. A network engineer must correct the traffic flow and route the traffic via AS 101. Which configuration must the engineer apply to R1 to correct the problem without affecting the second BGP attribute?

  A. bgp bestpath compare-routerid
  B. bgp bestpath med missing-as-worst
  C. bgp always-compare-med
  D. bgp default local-preference 200
  A. bgp bestpath compare-routerid

• Question 44:

  DRAG DROP

  Drag and drop the attributes for the BGP route selection on the left into the correct order on the right. Not all options are used.

  Select and Place:

• Question 45:

  

  Refer to the exhibit. P1 and PE3 Cisco IOS XR routers are directly connected and have this configuration applied. The BGP session is not coming up. Assume that there is no IP reachability problem and both routers can open tcp port 179 to each other.

  Which action fixes the issue?

  A. Change HMAC-MD5 to HMAC-SHA1-20
  B. Configure the send and accept lifetime under key 1
  C. Change HMAC-MD5 to MD5
  D. Change HMAC-MD5 to HMAC-SHA1-12
  B. Configure the send and accept lifetime under key 1

• Question 46:

  Refer to the exhibit.

  

  After maintenance to activate BGP neighbors for 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?

  A. Reset the BGP session between R1 and R2.
  B. Activate BGP neighbors between the new data center and R2 and R3.
  C. Establish new MPLS LSPs from R1 to R2, R3, and R4.
  D. Raise the maximum prefix limit on R2 to 1560 or more.
  A. Reset the BGP session between R1 and R2.

• Question 47:

  Refer to the exhibit.

  

  The service provider has deployed Segment Routing in its core. P2 is connected to P3 and P4 via a point-to-multipoint link, as shown. The service provider provides connectivity for a large enterprise with three main offices in different

  geographic regions. Each office is connected via one of the three PEs. The enterprise wants to implement multicast traffic across the service provider to stream mission-critical applications between sites. The applications will be sourced from

  a server connected to the network through PE2.

  Which action must the network-engineering team take so that multicast traffic will flow between the enterprise sites over the point-to-multipoint link?

  A. Implement RSVP to reserve bandwidth on the link between PE2 and P2.
  B. Implement PIM-DM to flood multicast traffic from the enterprise into the service provider core.
  C. Implement MLDP to allow multicast traffic to flow within the single AS.
  D. Implement SR Tree-SID to build a multicast replication tree over the point-to-multipoint link.
  D. Implement SR Tree-SID to build a multicast replication tree over the point-to-multipoint link.

• Question 48:

  For which reason can two devices fail to establish an OSPF neighbor relationship?

  A. The two devices have different process IDs
  B. The two devices have different network types
  C. The two devices have different router IDs
  D. The two devices have the same area ID
  B. The two devices have different network types

• Question 49:

  What is a feature of SR-PCE?

  A. It learns the topology information via OSPF or IS-IS only.
  B. It learns the topology information via OSPF or IS-IS or through BGP-LS.
  C. It uses the IGP metric in its path calculations to optimize reachability.
  D. It uses the TE metric in its path calculations to optimize the cumulative TE metric.
  B. It learns the topology information via OSPF or IS-IS or through BGP-LS.

• Question 50:

  Refer to the exhibit

  

  A network engineer configured the redistribute connected subnets route-map filtering command on R1 to redistribute connected interfaces to the OSPF process

  The engineer also wants to filter out IP address 10 0 1 0/24. but the prefix still appears in the routing tables of the other routers on the network.

  Which action corrects the problem?

  A. Remove route-map sequence 30.
  B. Add a set statement to route-map sequence 20.
  C. Change the deny statement in access list 2 to permit
  D. Remove the subnets keyword from the redistribute connected subnets route-map filtering command.
  C. Change the deny statement in access list 2 to permit
