A network engineer must connect two sites across a public network using a secure tunneling technology that supports multicast traffic. Which technology should be selected?

  1. IPsec
  2. GRE
  3. PPTP
  4. GRE over IPsec

Answer(s): D



A branch office has a primary L3VPN MPLS connection back to the main office and an IPSEC VPN tunnel that serves as backup. Which design ensures that data is sent over the backup connection only if the primary MPLS circuit is down?

  1. Use EIGRP to establish a neighbor relationship with the main office via L3VPN MPLS and the IPSEC VPN tunnel.
  2. Use BGP with the multipath feature enabled to force traffic via the primary path when available.
  3. Use static routes tied to an IP SLA to prefer the primary path while a floating static route points to the backup connection.
  4. Use OSPF with a passive-interface command on the backup connection.

Answer(s): C



Which solution allows overlay VNs to communicate with each other in an SD-WAN Architecture?

  1. External fusion routers can be used to map VNs to VRFs and selectively route traffic between VRFs.
  2. GRE tunneling can be configured between fabric edges to connect one VN to another.
  3. SGTs can be used to permit traffic from one VN to another.
  4. Route leaking can be used on the fabric border nodes to inject routes from one VN to another.

Answer(s): B



What are two benefits of designing an SD-WAN network fabric with direct Internet access implemented at every site? (Choose two.)

  1. It decreases latency to applications hosted by public cloud service provider.
  2. It decreases latency on Internet circuits.
  3. It increases the speed of delivery of site deployments through zero-touch provisioning.
  4. It increases the total available bandwidth on Internet circuits.
  5. It alleviates network traffic on MPLS circuits.

Answer(s): A,E
