Cisco CCNP Service Provider 350-501 Questions & Answers

• Question 31:

  A customer site is being connected to a Frame Relay network via a T1 link. The customer has a contract for 512 kbps service with a Tc value of 125 ms. Under peak line conditions customer traffic can reach four times the contracted speed. Which QoS configuration must the service provider implement to limit the customer to the contracted values?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: D

• Question 32:

  

  Refer to the exhibit. A host connected to R3 must connect with a server on R1 that provides critical, time-sensitive data. Traffic between the host and server must always be given bandwidth to traverse the links when they are congested, with other traffic being dropped. How must the network engineer implement a QoS strategy with classification to ensure that the traffic is given the appropriate bandwidth?

  A. Implement policing to rate-limit noncritical traffic that exceeds designated thresholds.

  B. Implement traffic shaping to delay noncritical traffic when the link is congested.

  C. Implement strict priority to guarantee bandwidth for the server traffic.

  D. Implement FIFO to guarantee that the server traffic is sent first while other traffic is queued.

  Correct Answer: C

• Question 33:

  How is RSVP used with MPLS traffic engineering tunnels?

  A. It assigns a tag to a packet as it travels through the tunnel.

  B. It removes and reassigns an MPLS label when the packet enters the tunnel.

  C. It reserves bandwidth along the path of the tunnel.

  D. It reduces the CPU burden when a packet travels through the tunnel.

  Correct Answer: C

• Question 34:

  

  Refer to the exhibit. Tier 1 ISP A purchased several Tier 2 ISPs to increase their customer base and provide more regional coverage. ISP A plans to implement MPLS services in the access layer, with scalability up to 100,000 devices in one packet network and service recovery up to 50 ms. The network architect decided to use different independent IGP and LDP domains and interconnect LSPs that are based on RFC 3107. Which two actions must the network engineer perform to meet the requirements? (Choose two.)

  A. Implement BGP inline RR functionality with next-hop-self capabilities on routers R2 and R3.

  B. Implement the IS-IS routing protocol on the access domain.

  C. Implement BGP connectivity between routers R1 and R4 with VPNv4 address family enabled.

  D. Configure three OSPF areas, with Area 0 in the core domain, and Areas 2 and 3 in the aggregation domain.

  E. Implement BGP PIC core functionality on routers R2 and R3.

  Correct Answer: AE

• Question 35:

  

  Refer to the exhibit. Tier 1 ISP A is connected to small Tier 3 ISP B. The EBGP routing protocol is used for route exchange. The networking team at ISP A noticed the flapping of BGP sessions with ISP B. The team decides to improve stability on the network by suppressing the subnet for 30 minutes when a session begins to flap. Which action must the team perform to meet this goal?

  A. Implement BGP route dampening on ISP A router R1 with the bgp dampening 15 700 1500 30 command.

  B. Implement a BGP route withdraw-delay timer on ISP B router R3 with the bgp withdraw-delay 30 15 90 30 command.

  C. Implement a BGP route-penalty timer on ISP A router R1 with the bgp penalty-timer 30 250 750 15 command.

  D. Implement BGP route suppression on ISP A router R2 with the bgp suppression 30 600 1200 30 command.

  Correct Answer: A

• Question 36:

  Which core component of MDT describes the data that an MDT-capable device streams to a collector?

  A. sensor path

  B. encoder

  C. transport protocol

  D. subscription

• Question 37:

  An engineer working for a telecommunication company with an employee ID: 1234:56:789 must configure an OSPF router in a multivendor network so that it performs NSF in the event of a route processor switchover. Which configuration must the engineer apply?

  A. router ospf 1 nsf cisco

  B. router ospf 1 nsf cisco helper

  C. router ospf 1 nsf ietf helper

  D. router ospf 1 nsf ietf

• Question 38:

  

  Refer to the exhibit. Which part of the diagram will host OpenStack components?

  A. UCS Series

  B. Aggregation

  C. Access

  D. Core

  Correct Answer: A

• Question 39:

  

  Refer to the exhibit. A client wants to filter routes to a BGP peer to limit access to restricted areas within the network. The engineer configures the route map ciscotest to filter routes from the BGP neighbor. The engineer also sets a tag that will be used for QoS in the future. Which task must be performed to complete the implementation?

  A. Create a route map, configure BGP with an IPv4 address family, and activate the neighbor.

  B. Attach the new route map to the BGP neighbor statement in the inbound direction.

  C. Create a policy map named ciscotest and apply it to inbound traffic on the link that is directly connected to the BGP neighbor.

  D. Add a route map statement with sequence 40 that links a BGP community to the routing protocol.

  Correct Answer: B

• Question 40:

  

  Refer to the exhibit. R1 has two upstream Tier 1 service providers. BGP is in use as the exterior routing protocol, and ISP_A and ISP_B are sending the full BGP table. A network engineer must assign local-preference 70 to all routes with multiple exit discriminator 30. Which configuration must the network engineer apply?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: C
