Question 66

Which component is part of the Cisco SD-Access overlay architecture?

  1. border node
  2. spine node
  3. leaf node
  4. Cisco DNA Center

Question 67

How are wireless endpoints registered in the HTDB in a Cisco SD-Access architecture?

  1. Border nodes first register endpoints and then update the HTDB.
  2. Fabric WLCs update the HTDB as new clients connect to the wireless network.
  3. Fabric APs update the HTDB with the clients' EID and RLOC.
  4. Fabric edge nodes update the HTDB based on CAPPWAP messaging from the AP.

Question 68

What is the purpose of a Cisco SD-Access underlay network?

  1. to abstract IP-based connectivity from physical connectivity
  2. to emulate LAN segments to transport Layer 2 frames over a Layer 3 network
  3. to establish physical connectivity between switches and routers
  4. to provide virtualization by encapsulating network traffic over IP tunnels

Question 69

Drag and drop the components in a Cisco SD-Access architecture from the left onto their descriptions on the right. Select and Place:

Question 70

Refer to the exhibit. The distribution switches serve as the Layer 3 boundary. HSRP preemption is enabled. When the primary switch comes back after a failure, traffic is initially dropped. Which solution must be implemented to improve the design?

  1. Increase the hello timers on both HSRP devices.
  2. Use the preempt delay feature on the backup HSRP device.
  3. Use the preempt delay feature on the primary HSRP device.
  4. Configure a higher mac-refresh interval on both HSRP devices.
