Cisco 300-415 Online Questions & Answers

• Question 541:

  The application team is getting ready to deploy a new business-critical application to the network. To protect the traffic, the network team must add another queue to the QoS map and then deploy the map to the fabric.

  Which configuration step must be completed prior to adding the queue to the QoS map and applying it?

  A. The relationship between the new QoS class and the hardware queue must be configured from the "lists" page of the Local Policy section of vManage. The QoS map is then applied to the WAN interface.
  B. The relationship between the new QoS class and the hardware queue must be configured from the "lists" page of the Local Policy section of vManage. The QoS map is then applied to the service-side interface.
  C. The relationship between the new QoS class and the hardware queue must be configured from the "lists" page of the Centralized Policy section of vManage. The QoS map is then applied to the service-side interface.
  D. The relationship between the new QoS class and the hardware queue must be configured from the "lists" page of the Centralized Policy section of vManage. The QoS map is then applied to the WAN interface.
  C. The relationship between the new QoS class and the hardware queue must be configured from the "lists" page of the Centralized Policy section of vManage. The QoS map is then applied to the service-side interface.

• Question 542:

  Which two resource data types are used to collect information for monitoring using REST API in Cisco SD-WAN? (Choose two.)

  A. POST
  B. PUT
  C. scalar
  D. array
  E. DELETE
  C. scalar
  D. array

  ---

  Explanation

  Scalar data types represent individual data values, while array data types represent collections of data values. These data types are commonly used in REST APIs to retrieve and manage information in the context of monitoring and managing network resources. Options A, B, and E (POST, PUT, DELETE) are HTTP methods, not resource data types.

• Question 543:

  Refer to the exhibit.

  

  

  vManage and vBond have an issue establishing a connection to each other.

  Which configuration resolves the issue?

  A. Reconfigure the timezone on vBond to Europe/London.
  B. Configure vManage with the vBond address as 172.16.1.33.
  C. Configure tunnel interface under interface ge0/0 of vBond.
  D. Configure the Site-ID for vBond to 1.
  B. Configure vManage with the vBond address as 172.16.1.33.

• Question 544:

  Which pathway under Monitor > Network > Select Device is used to verify service insertion configuration?

  A. System Status
  B. Troubleshooting
  C. Real Time
  D. Events
  C. Real Time

  ---

  Explanation

  Realtime On a hub device, view the configured services

  From the Cisco vManage menu:

  View the configured services on the Real Time monitoring page (Monitor > Devices > hub-device > Real Time)

  Troubleshooting On a spoke device, view the details of the service chain path.

  Using Cisco vManage:

  View the service chain path on the Traceroute page (Monitor > Devices > spoke-device > Troubleshooting > Connectivity > Trace Route). Enter the destination IP, VPN, and source interface for the desired path.

• Question 547:

  Which set of elements are verified by the controller to confirm the identity of edge devices?

  A. certificates, organization name, and serial number of the device
  B. organization name, serial number, and system IP of the device
  C. certificates, organization name, and vBond domain
  D. certificates, system IP, and vBond domain
  A. certificates, organization name, and serial number of the device

• Question 548:

  An engineer is configuring a list that matches all IP prefixes with lengths from /1 to /16 in a centralized control policy.

  Which list accomplishes this task?

  A. 0.0.0.0/1 le 16
  B. 0.0.0.0/0 ge 1
  C. 0.0.0.0/0 le l6
  D. 0.0.0.0/16 ge 1
  A. 0.0.0.0/1 le 16

  ---

  Explanation

  0.0.0.0/0 le length - Match any IP prefix whose length is less than or equal to length. For example, ip-prefix 0.0.0.0/0 le 16 matches all IP prefixes with lengths from /1 through /16.

• Question 549:

  Which protocol is used to measure jitter, loss, and latency on SD-WAN overlay tunnels?

  A. QoE
  B. OMP
  C. BGP
  D. BFD
  D. BFD

• Question 550:

  Refer to the exhibit.

  

  An engineer is configuring Application-Aware Routing using an SLA to ensure that traffic can be automatically switched to a circuit with better statistics when one of the circuits faces issues. To achieve this, the engineer is modifying the BFD configurations based on these requirements:

  1. Use the maximum number of BFD samples to determine delay, jitter, and loss per circuit.

  2. All BFD samples must be collected for a total duration of 60 seconds or less.

  Which configuration accomplishes this task?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D
