300-515 Exam Training Practice Tests (Cisco Implementing Cisco Service Provider VPN Services)]

Question 1

Refer to the exhibit. OSPF is used as an underlayer routing protocol in the backbone network of this ISP. A network engineer recently configured R1 with ip cef and mpls label range 1000 2000.
Several days later, the engineer replaced a failed RP module on R1. After the replacement, one of the customer's MPLS LSPs went down with the error message LSP-ERROR-Indication:No Label Resources. Which action must the engineer take to resolve the issue?

A. Configure mpls ldp neighbor 10.0.0.2 targeted under the global configuration. B. Configure mpls mtu 1600 under interface Gi0/0/0. C. Configure xconnect 10.0.0.2 100 encapsulation mpls vian 10 under interface Gi0/0/0. D. Configure redistribute connected under the OSPF configuration.

Question 2

Refer to the exhibit. What is shown in this output?

A. the labels received and advertised on PE1 B. LDP neighbor statuses C. BGP is used between neighbors that are exchanging MPLS labels D. local and outgoing abels are updated in hardware

Correct Answer: A

Question 3

Refer to the exhibit. What is the effect of this configuration?

A. An LSP virtual interface tunnel is created. B. A Cisco MPLS TE tunnel is generated with 192.168.1.2 as the source IP address of router 1. C. The mroute table is cleared. D. Router 1 accepts multicast routes with a tag of 12:1

Correct Answer: D

Question 4

Refer to the exhibit. A customer reported that traffic is failing to pass between Site-X and Site-Y.
The network engineer already verified that the connectivity between IS-IS and LDP is up from TP21 to TP31. PW 1000 and PW 2000 are configured with SPX. Which action must the engineer take to resolve the issue?

A. Configure SPX with the pw-class dynamic_mpls command under xconnect group MS-PW10 for SPX neighbors. B. Configure neighbor 10.10.10.1 pw-id 1000 under a different xconnect group name. C. Enable preferred-path interface tunnel under the pw-class configuration on SPX. D. Enable control-word under the pw-class configuration on SPX.

Question 5

How is the underlay label managed in L3VPN data plane operations?

A. The label is swapped at each label-switching router in the service provider network. B. The label is unchanged on provider routers and popped at the egress router. C. The label is pushed at the provider edge router and popped at the next provider router. D. The label is pushed at the ingress LER and remains unchanged through the MPLS label swap process in the network.

Question 6

A major company is updating its network environment to support the streaming of high-bandwidth video from a central data center to multiple remote offices. The company offices are connected across an ISP MPLS network, so an engineer at the ISP has been asked to configure MLDP to support the new streaming requirements. Which action must the engineer take so that the high- bandwidth data streams correctly from the data center to the remote offices?

A. Configure a data threshold that triggers a data MDT when it is exceeded. B. Disable MLDP multipath forwarding to prevent streaming data from overloading all the links between the data center and the remote offices. C. Disable recursive forwarding so that the route to the data center is populated correctly in the RIB at each site. D. Configure the MDT type to be PIM-SM.

Question 7

How do EFPs distinguish flows?

A. by analyzing MPLS labels and QoS tags B. by associating each flow with a single IP address C. by analyzing QoS tags D. by identifying one or more VLAN tag with wildcards
