Cisco CCNP Service Provider 350-501 Questions & Answers

• Question 501:

  A. The same QoS policy is applied to all customer traffic on the egress PE.

  B. If the outer EXP is changed, it is copied to the DSCP value.

  C. The MPLS EXP bits are set by the CE.

  D. The DSCP value determines how the packet is forwarded

  Correct Answer: A

• Question 502:

  Which is the benefit of implementing model-driven telemetry in a service provider environment?

  A. It reduces the number of network monitoring tools that are necessary to verify device statistics.

  B. It increases the efficiency of SNMP by pulling system data to requesting servers.

  C. It reduces or eliminates the need to monitor Layer 2 traffic between switches.

  D. It uses reliable transport to push Information to network monitoring tools

  Correct Answer: D

• Question 503:

  Which configuration mode do you use to apply the mpls Idp graceful-restart command in IOS XE Software? MPLS

  A. MPLS

  B. LDP neighbor

  C. global

  D. interface

  Correct Answer: C

• Question 504:

  

  Refer to the exhibit. Four midsize service providers provide access to different customers that use Layer 3 VPN services to enable communication across geographic regions. The service providers are connected as shown in the exhibit, and the PEs have established eBGP relationships. PE4 has an IBGP relationship with PE5. The routes that PE4 learns from PE5 must reach the other PE routers, but they are absent from the routing tables on the other PES. Which action should the engineers take to correct the problem?

  A. Configure a peering between all five Pes.

  B. Disable BGP synchronization on PE4.

  C. Enable BOP IPv4 unicast on PE4 and PE5

  D. Advertise the route targets for PE5 to the other PEs

  Correct Answer: A

• Question 505:

  

  Refer to the exhibit. A network engineer is configuring an SNMP community on router RB with these requirements:

  Allow read-only access for all objects to members of Access-List 10 that use the comaccess community string.

  Other SNMP managers must not have access to objects. SNMP authentication failure traps must be sent to SNMPv2c and then to the host using SNMPv2c with the public community string.

  Which configuration meets these requirements?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: A

• Question 506:

  

  Refer to the exhibit. A company recently deployed a new network using OSPF in the core to share routes. The network administrator selected OSPF as the routing protocol because of its ability to maintain a route database. When the new network was started up, all routers booted normally, but the link between routers R1 and R2 failed to come up. The two routers are located in the same rack at the data center. Which task should an engineer perform to correct the problem?

  A. Synchronize the dead timers.

  B. Change one of the OSPF router IDs so that the router IDs are in different subnets

  C. Change the OSPF process ID on one of the devices so that the two IDs match

  D. Configure the MTUs on the interface to match.

  Correct Answer: D

• Question 507:

  

  Refer to the exhibit. All BGP peering in AS 65101 and 65201 is enabled. The operations team is told that traffic destined to 192.168.1.1/32 from R4 does not use the path R3-R2-R1 as expected. An engineer debugs the issue and determines that 192.168.1.1/32 is advertised in the BGP routing table on R1. Which action resolves the issue?

  A. Enable no synchronization on R2 m AS65101.

  B. Apply route-map High-LP out for prefix 192.168.1.1/32 on R1 with R2 BGP peering.

  C. Apply redistribute ospf 10 on R1 in BGP AS 65101.

  D. Configure network 192.168.1.1 mask 255.255.255.255 in BGP AS 65101 on R2

  Correct Answer: A

• Question 508:

  

  Refer to the exhbit. ISP A has a BGP peering with ISP C with the maximum-prefix 150 configuration on R1. After a recent security breach on the ISP A network, a network engineer has been asked to enable a lightweight security mechanism to protect the R1 CPU and BGP membership from spoofing attacks. Which solution must ISP A implement?

  A. Configure bgp maxas-limit 1 in the IPv4 address family urateUhe global BGP configuration.

  B. Configure neighbor 10.163.83.54 enable-connected-check under the BGP IPv4 address family.

  C. Configure neighbor 10.163.83.55 password Cisco under the global BGP IPv4 address family.

  D. Configure neighbor 10.163.83.55 ttl-stcurity hops 2 under the global BGP configuration.

  Correct Answer: D

• Question 509:

  Refer to the exhibit.

  

  An engineer is configuring multitopology IS-IS for IPv6 on router R1. Which additional configuration must be applied to the router to complete the task?

  A. R1# configure terminal R1(config)# router isis area2 R1(config-router)# address-family ipv6 R1(config-router-af)# multi-topology Most Voted

  B. R1# configure terminal R1(config)# router isis area1 R1(config-router)# metric-style wide level-2 R1(config-router)# address-family ipv6 R1(config-router-af)# multi-topology

  C. R1# configure terminal R1(config)# router isis area2 R1(config-router)# metric-style wide R1(config-router)# address-family ipv6 R1(config-router-af)# multi topology

  D. R1# configure terminal R1(config)# router isis area1 R1(config-router)# metric-style wide level-1 R1(config-router)# address-family ipv6 R1(config-router-af)# multi topology

  Correct Answer: A
