Cisco 350-401 Online Practice Questions and Exam Preparation

Cisco 350-401 Online Questions & Answers

• Question 311:

  What does a YANG model provide?

  A. standardized data structure independent of the transport protocols
  B. creation of transport protocols and their interaction with the OS
  C. user access to interact directly with the CLI of the device to receive or modify network configurations
  D. standardized data structure that can be used only with NETCONF or RESTCONF transport protocols
  A. standardized data structure independent of the transport protocols

  ---

  Explanation

  YANG is a standards-based, extensible data modeling language that is used to model the configuration and operational state data, remote procedure calls (RPCs), and server event notifications of network devices. The NETMOD working group in the IETF originally designed YANG to model network management data and to provide a standard for the content layer of the Network Configuration Protocol (NETCONF) model. However, YANG is protocol independent, and YANG data models can be used independent of the transport or RPC protocol and can be converted into any encoding format supported by the network configuration protocol.

• Question 312:

  How does an on-premises infrastructure compare to a cloud infrastructure?

  A. On-premises can increase compute power faster than cloud
  B. On-premises requires less power and cooling resources than cloud
  C. On-premises offers faster deployment than cloud
  D. On-premises offers lower latency for physically adjacent systems than cloud.
  D. On-premises offers lower latency for physically adjacent systems than cloud.

• Question 313:

  Refer to the exhibit.

  

  Which antenna emits this radiation pattern?

  A. omnidirectional
  B. RP-TNC
  C. dish
  D. Yagi
  A. omnidirectional

• Question 314:

  Select and Place:

  

  

• Question 315:

  Refer to the exhibit.

  

  What is the result when a switch that is running PVST+ is added to this network?

  A. DSW2 operates in Rapid PVST+ and the new switch operates in PVST+
  B. Both switches operate in the PVST+ mode
  C. Spanning tree is disabled automatically on the network
  D. Both switches operate in the Rapid PVST+ mode.
  A. DSW2 operates in Rapid PVST+ and the new switch operates in PVST+

  ---

  Explanation

  From the output we see DSW2 is running in RSTP mode (in fact Rapid PVST+ mode as Cisco does not support RSTP alone). When a new switch running PVST+ mode is added to the topology, they keep running the old STP instances as RSTP (in fact Rapid PVST+) is compatible with PVST+.

• Question 316:

  Which two prerequisites must be met before Cisco DNA Center can provision device? (Choose two.)

  A. Cisco DNA Center must have the software image for he provisioned device in its image repository.
  B. The provisioned device must be put into bootloader mode.
  C. The provisioned device must be configured with CLI and SNMP credentials that are known to Cisco DNA Center.
  D. Cisco DNA Center must have IP connectivity to the provisioned device.
  E. The provisioned device must recognize Cisco DNA Center as its LLDP neighbor.
  C. The provisioned device must be configured with CLI and SNMP credentials that are known to Cisco DNA Center.
  E. The provisioned device must recognize Cisco DNA Center as its LLDP neighbor.

• Question 317:

  What is a capability of the Cisco DNA Center southbound API?

  A. It adds support for managing non-Cisco devices from Cisco DNA Center.
  B. It connects to ITSM services such as ServiceNow.
  C. It sends webhooks from Cisco DNA Center when alerts are triggered.
  D. It allows administrators to make API calls to Cisco DNA Center.
  A. It adds support for managing non-Cisco devices from Cisco DNA Center.

• Question 318:

  

  Refer to the exhibit.

  What is the value of the variable list after the code is run?

  A. [1, 10, 10, 10]
  B. [1, 2, 10]
  C. [1, 2, 10, 4]
  D. [1, 2, 3, 10]
  D. [1, 2, 3, 10]

  ---

  Explanation

  The first element of an array is at index 0 so list[3] gets the fourth element of the array.

• Question 319:

  What happens when a FlexConnect AP changes to standalone mode?

  A. All controller-dependent activities stop working except the DFS.
  B. All client roaming continues to work
  C. Only clients on central switching WLANs stay connected.
  D. All clients on an WLANs are disconnected
  A. All controller-dependent activities stop working except the DFS.

  ---

  Explanation

  When a FlexConnect access point enters standalone mode, it disassociates all clients that are on centrally switched WLANs. [ not all clients, locally switched WLAN clients stay connected]

  Controller-dependent activities, such as network access control (NAC) and web authentication (guest access), are disabled, and the access point does not send any intrusion detection system (IDS) reports to the controller.

  Most radio resource management (RRM) features (such as neighbor discovery; noise, interference, load, and coverage measurements; use of the neighbor list; and rogue containment and detection) are disabled. However, a FlexConnect access point supports dynamic frequency selection in standalone mode.

  C. Uses a pull model, where the end devices pull configuration files from the Ansible server.
  D. Utilizes SSH.
  B. Utilizes the concept of playbooks to execute the configuration.
