  Which protocol is used by the REST API to communicate with network devices in the Cisco SD-WAN network?

  A. HTTP
  B. SSL
  C. IPsec
  D. SSH
  A. HTTP

  ---

  Explanation

  A REST API is a web service that adheres to the REST, or Representational State Transfer, architecture. The REST architecture uses a stateless, clienterver, cacheable communications protocol. The Cisco SD-WAN vManage NMS web server uses HTTP and its secure counterpart, HTTPS, as the communications protocol. REST applications communicate over HTTP or HTTPS using standard HTTP methods to make calls between network devices.

• Question 253:

  Which Cisco SD-WAN component provides a secure data plane with remote vEdge routers?

  A. vManage
  B. vSmart
  C. vBond
  D. vEdge
  D. vEdge

• Question 254:

  What are the two reasons a customer chooses to use IPsec tunnels over GRE? (Choose two.)

  A. IPsec failure detection is faster.
  B. Generally, they provide a higher bandwidth for tunnel connection.
  C. CFlowd is required.
  D. A WAN Edge router is behind NAT.
  E. IPsec is more secure.
  A. IPsec failure detection is faster.
  E. IPsec is more secure.

• Question 255:

  Which queue must an engineer configure for control and BFD traffic for convergence on a WAN Edge router?

  A. queue 0
  B. queue 1
  C. queue 2
  D. queue 7
  A. queue 0

  ---

  Explanation

  Each interface has eight queues on hardware vEdge routers, numbered from 0 to 7. Queue 0 is reserved and is used for both control traffic and low-latency queuing (LLQ) traffic. For LLQ, any class that is mapped to queue 0 must also be configured to use LLQ. All control traffic is transmitted. Queues 1 to 7 are available for data traffic.

• Question 256:

  Refer to the exhibit.

  A. APIC-EM
  B. vSmart
  C. vManage
  D. vBond
  C. vManage

  ---

  Explanation

  vManage - The vManage controller is the centralized network management system that provides the GUI interface. This single pane of glass allows easy deployment, configuration, monitoring, and troubleshooting of the Cisco SD-WAN network.
