  B. 12345
  C. 12346
  D. 12347
  C. 12346

• Question 532:

  A. 1
  B. 2
  C. 3
  D. 4

• Question 534:

  In Cisco SD-WAN, what protocol is used for control connections between SD-WAN devices?

  A. BGP
  B. OSPF
  C. DTLS
  D. OMP
  C. DTLS

  ---

  Explanation

  In the reference link under the 'Control Plane Authentication' part, you can find the following:

  Then, during the automatic authentication process, as pairs of devices (routers and controllers) are establishing DTLS control connections, each device compares the serial numbers (and for routers, the chassis numbers) to those in the files installed on the router.

  DTLS is the connection that facilitates the exchange of OMP information between the devices. In vManage the number of control connections also shows the amount of DTLS connections to/from a device. OMP is not the control connection, it's the control plane management protocol.

• Question 535:

  Refer to the exhibit.

  

  An engineer is troubleshooting a control connection issue on a WAN Edge device that shows socket errors. The packet capture shows some ICMP packets dropped between the two devices.

  Which action resolves the issue?

  A. Remove IP duplication in the network and configure a unique IP address.
  B. Recover vBond or wait for the controller to reload, which could be caused by a reset.
  C. Recover the vManage controller that is down in a high availability cluster.
  D. Change the system IP or restart the WAN Edge if the system IP is changed.
  A. Remove IP duplication in the network and configure a unique IP address.

• Question 536:

  Which configuration accomplishes the task?

  A. vpn 0 tloc-extension interface interface-name
  B. interface interface-name tloc-extension
  C. tloc-extension interface interface-name
  D. vpn 0 interface interface-name tloc-extension interface-name
  D. vpn 0 interface interface-name tloc-extension interface-name

  B. It carries control out-of-bond network management traffic among the Viptela devices in the overlay network.
  C. It carries control traffic over secure IPsec connections between vSmart controllers and vEdge routers, and between vSmart and vManager
  D. It carries control traffic over secure DTLS or TLS connections between vSmart controllers and vEdge routers, and between vSmart and vBond
  D. It carries control traffic over secure DTLS or TLS connections between vSmart controllers and vEdge routers, and between vSmart and vBond

• Question 540:
