Demo Questions
Question 1
Which solution allows overlay VNs to communicate with each other in an SD-WAN Architecture?
- A: External fusion routers can be used to map VNs to VRFs and selectively route traffic between VRFs.
- B: GRE tunneling can be configured between fabric edges to connect one VN to another.
- C: SGTs can be used to permit traffic from one VN to another.
- D: Route leaking can be used on the fabric border nodes to inject routes from one VN to another.
Question 2
An engineer must design a VPN solution for a company that has multiple branches connecting to a main office. What are two advantages of using DMVPN instead of IPsec tunnels to accomplish this task? (Choose two.)
- A: support for AES 256-bit encryption
- B: greater scalability
- C: support for anycast gateway
- D: lower traffic overhead
- E: dynamic spoke-to-spoke tunnels
Question 3
Which NETCONF operation creates filtering that is specific to the session notifications?
- A: <create-subscription>
- B: <commit>
- C: <notification>
- D: <logging>
Question 4
An enterprise customer has these requirements:
end-to-end QoS for the business-critical applications and VoIP services based on CoS marking.
flexibility to offer services such as IPv6 and multicast without any reliance on the service provider.
support for full-mesh connectivity at Layer 2.
Which WAN connectivity option meets these requirements?
end-to-end QoS for the business-critical applications and VoIP services based on CoS marking.
flexibility to offer services such as IPv6 and multicast without any reliance on the service provider.
support for full-mesh connectivity at Layer 2.
Which WAN connectivity option meets these requirements?
- A: VPWS

Question 5
What is a benefit of using VRRPv3 as compared to VRRPv2?
- A: VRRPv3 supports IPv4 and IPv6
- B: VRRPv3 supports authentication
- C: VRRPv3 supports preemption
- D: VRRPv3 supports stateful switchover
Question 6
A customer is discussing QoS requirements with a network consultant. The customer has specified that end-to-end path verification is a requirement. Which QoS solution meets this requirement?
- A: IntServ model with RSVP to support the traffic flows
- B: DiffServ model with PHB to support the traffic flows
- C: marking traffic at the access layer with DSCP to support the traffic flows
- D: marking traffic at the access layer with CoS to support the traffic flows
Question 7
Which nonproprietary mechanism can be used to automate rendezvous point distribution in a large PIM domain?
- A: Embedded RP
- B: BSR
- C: Auto-RP
- D: Static RP
Question 8
Which QoS feature responds to network congestion by dropping lower priority packets?
- A: CBWFQ
- B: tail drop
- C: WRED
- D: strict priority
Question 9
Which two BGP features will result in successful route exchanges between eBGP neighbors sharing the same AS number? (Choose two.)
- A: advertise-best-external
- B: bestpath as-path ignore
- C: client-to-client reflection
- D: as-override
- E: allow-as-in
Question 10

- A: Multihop
- B: Multipath Load Sharing
- C: Next-Hop Address Tracking
- D: AS-Path Prepending
