Cisco CCNP Service Provider 350-501 Questions & Answers

• Question 41:

  

  Refer to the exhibit. To optimize network operations, the senior architect created this Python 3.9 script for network automation tasks and to leverage Ansible 4.0 playbooks. Devices in the network support only RFC 2617-based authentication. What does the script do?

  A. The script performs a configuration sanity check on the device with IP address 172.168.211.65 via HTTP and returns an alert if the payload field fails to match.

  B. The script leverages REST API calls and configures interface GigabitEthernet0/1 with IP address 10.1.131.112/30.

  C. The script parses the JSON response from the router at IP address 172.168 211.65 and checks if the interface GigabitEthernet0/1 with IP address 10.1.131.112 exists on the router.

  D. The script logs in via SSH and configures interface GigabitEthernet0/1 with IP address 10 1.131.112/30.

  Correct Answer: B

• Question 42:

  

  Refer to the exhibit. The operations team for a service provider network is implementing a route map policy. OSPF area 0 should originate the default route with a type 2 metric of 2 when the application server on the connected interface

  (192.168.1.1)

  is up. Routers RL and RM have set up OSPF peering with other adjacent routers. Which action meets this requirement?

  A.

  Apply default-information originate route-map ospf-default-route on router RL.

  B.

  Apply default-information originate route-map ospf-default-route on router RM.

  C.

  Configure distribute-list route-map ospf-default-route out on router RM.

  D.

  Configure distribute-list route-map ospf-default-route out on router RL.

  Correct Answer: A

• Question 43:

  

  Refer to the exhibit. The ISP is implementing a new hosting-as-a-service solution for its business customers. Service accessibility must be unique and separate for each customer. The network architect must ensure that multiple paths toward the hosting-as-a-service solution are always available. Basic protection against traffic black-holing on the MPLS network is required in case of link failure. Which two actions must the engineering team perform to meet the requirements? (Choose two.)

  A. Configure the fast-hello command under the IS-IS routing protocol with the BGP multipath 2 option enabled.

  B. Enable the VRF-Lite feature on router R4 and enable BGP address-family VPNv4.

  C. Create the hosting-as-a-service VRF on router R4 and configure it with the route target both 65123:88 command.

  D. Configure the fast-reroute per-prefix command for the IS-IS protocol in the MPLS network and enable the BGP route-reflector feature on R2.

  E. Configure the mpls ldp sync command in the MPLS network with the BGP additional-paths receive and additional-paths send options.

  Correct Answer: BE

• Question 44:

  

  Refer to the exhibit. An engineer must implement a traceroute operation to verify the R1 point-to-multipoint LSP connections. The traceroute operation must return all labels and hop-by-hop IP addresses for destinations 10.20.0.1, 10.30.0.1, and 10 40.0.1, and the maximum number of hops is 4. Which command must be executed to meet the requirements?

  A. traceroute mpls ipv4 10.30.0.1/32 fec-type generic

  B. traceroute mpls ipv4 10.20.0.1/32 ttl 4

  C. traceroute mpls traffic-eng tunnel-mte 10 ttl 4

  D. traceroute mpls traffic-eng tunnel-mte 10 responder-id 10.40.0.1

  Correct Answer: C

  Correct Answer:

  

• Question 47:

  DRAG DROP

  A network engineer is adding 10Gbps link to an existing 2X1Gbps LACP-based LAG to augment its capacity. Network standards require a bundle interface to be take out of service if one of its member links does down, and the new link must be added with minimal impact to the production network. Drag and drop the tasks that the engineer must perform from the left into the sequence on the right. Not all options are used.

  Correct Answer:

  

• Question 49:

  DRAG DROP

  A network engineer is adding an additional 10Gbps link to an existing 2x10Gdps LACP-based LAG to augment its capacity. Network standards require a bundle interface to be taken out of service if one of its member links goes down, and the new link must be added with minimal impact to the production network. Drag and drop the tasks that the engineer must perform from the left into the sequence on the right. Not all options are used.
