Cisco CCNP Enterprise 350-401 Questions & Answers

• Question 571:

  When does a stack master lose its role?

  A. When the priority value of a stack member is changed to a higher value

  B. when a switch with a higher priority is added to the stack

  C. when the stack master is reset

  D. when a stack member fails

  Correct Answer: C

  A stack master retains its role unless one of these events occurs:

  1.

  The switch stack is reset.*

  2.

  The stack master is removed from the switch stack.

  3.

  The stack master is reset or powered off.

  4.

  The stack master fails.

  5.

  The switch stack membership is increased by adding powered-on standalone switches or switch stacks.*

  In the events marked by an asterisk (*), the current stack master might be re-elected based on the listed factors. When you power on or reset an entire switch stack, some stack members might not participate in the stack master election. Stack members that are powered on within the same 20-second time frame participate in the stack master election and have a chance to become the stack master. Stack members that are powered on after the 20-second time frame do not participate in this initial election and become stack members. All stack members participate in re-elections. For all powering considerations that affect stack-master elections, see the "Switch Installation" chapter in the hardware installation guide. The new stack master becomes available after a few seconds. In the meantime, the switch stack uses the forwarding tables in memory to minimize network disruption. The physical interfaces on the other available stack members are not affected during a new stack master election and reset. After a new stack master is elected and the previous stack master becomes available, the previous stack master does not resume its role as stack master. As described in the hardware installation guide, you can use the Master LED on the switch to see if the switch is the stack master.

• Question 572:

  Which function does a Cisco SD-Access extended node perform?

  A. provides fabric extension to nonfabric devices through remote registration and configuration

  B. performs tunneling between fabric and nonfabric devices to route traffic over unknown networks

  C. used to extend the fabric connecting to downstream nonfabric enabled Layer 2 switches

  D. in charge of establishing Layer 3 adjacencies with nonfabric unmanaged node

  Correct Answer: C

• Question 573:

  When using BFD in a network design, which consideration must be made?

  A. BFD is used with first hop routing protocols to provide subsecond convergence.

  B. BFD is more CPU-intensive than using reduced hold timers with routing protocols.

  C. BFD is used with dynamic routing protocols to provide subsecond convergence.

  D. BFD is used with NSF and graceful to provide subsecond convergence.

• Question 574:

  An engineer applies this configuration to router R1. How does R1 respond when the user `cisco' logs in?

  

  A. It displays the startup conftg and then permits the user to execute commands

  B. It places the user into EXEC mode and permits the user to execute any command

  C. It displays the startup conflg and then terminates the session.

  D. It places the user into EXEC mode but permits the user to execute only the show startup-config command

  Correct Answer: A

• Question 575:

  Based on the router's API output in JSON format below, which Python code will display the value of the "hostname" key?

  

  A. json_data = json.loads(response.text) print(json_data[response][0][hostname])

  B. json_data = response.json() print(json_data[`response'][0][`hostname'])

  C. json_data = response.json() print(json_data[`response'][family][hostname'])

  D. json_data = json.loads(response.text) print(json_data[`response'][`family'][`hostname'])

  Correct Answer: B

  the output was generated from an API get request using "requests" library. https://www.geeksforgeeks.org/response-json-python-requests/

• Question 576:

  Refer to the exhibit.

  

  Both controllers are in the same mobility group. Which result occurs when client 1 roams between APs that are registered to different controllers in the same WLAN?

  A. Client 1 contact controller B by using an EoIP tunnel.

  B. CAPWAP tunnel is created between controller A and controller B.

  C. Client 1 users an EoIP tunnel to contact controller A.

  D. The client database entry moves from controller A to controller B.

  Correct Answer: D

  This is called Inter Controller-L2 Roaming. Inter-Controller (normally layer 2) roaming occurs when a client roam between two APs registered to two different controllers, where each controller has an interface in the client subnet. In this instance, controllers exchange mobility control messages (over UDP port 16666) and the client database entry is moved from the original controller to the new controller

• Question 577:

  Which collection contains the resources to obtain a list of fabric nodes through the vManage API?

  A. device management

  B. administration

  C. device inventory

  D. monitoring

  Correct Answer: C

  The collection that contains the resources to obtain a list of fabric nodes through the vManage API is the device inventory collection. This collection can be accessed through the Cisco Encor Documents and provides resources such as the Fabric Visualization, Device List, and Fabric Node Inventory APIs. These APIs can be used to obtain information about the fabric nodes, such as the device inventory, status, and version.

• Question 578:

  Refer to the exhibit.

  

  R1 and R2 are directly connected, but the BGP session does not establish. Which action must be taken to build an eBGP session?

  A. Configure ip route 1.1.1.1 0.0.0.0 192.168.12.1 on R2.

  B. Configure neighbor 192.168.12.1 activate under R2 BGP process.

  C. Configure neighbor 2.2.2.2 remote-as 65002 under R1 BGP process.

  D. Configure no neighbor 192.168.12.1 shutdown under R2 BGP process.

  Correct Answer: D

• Question 579:

  Where is the wireless LAN controller located in a mobility express deployment?

  A. There is no wireless LAN controller in the network.

  B. The wireless LAN controller is embedded into the access point.

  C. The wireless LAN controller exists in the cloud.

  D. The wireless LAN controller exists in a server that is dedicated for this purpose.

  Correct Answer: B

• Question 580:

  Refer to the exhibit.
