Demo Questions
Question 1
Which solution allows overlay VNs to communicate with each other in an SD-WAN Architecture?
- External fusion routers can be used to map VNs to VRFs and selectively route traffic between VRFs.
- GRE tunneling can be configured between fabric edges to connect one VN to another.
- SGTs can be used to permit traffic from one VN to another.
- Route leaking can be used on the fabric border nodes to inject routes from one VN to another.
Correct answer: B
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.)
- support for AES 256-bit encryption
- greater scalability
- support for anycast gateway
- lower traffic overhead
- dynamic spoke-to-spoke tunnels
Correct answer: BE
Question 3
Which NETCONF operation creates filtering that is specific to the session notifications?
- <create-subscription>
- <commit>
- <notification>
- <logging>
Correct answer: A
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?
1EFB657328D9343266DF00194B7D4255

Explanation:
Question 5
IntServ uses Resource Reservation Protocol (RSVP) to
What is a benefit of using VRRPv3 as compared to VRRPv2?
- VRRPv3 supports IPv4 and IPv6
- VRRPv3 supports authentication
- VRRPv3 supports preemption
- VRRPv3 supports stateful switchover
Correct answer: A
Explanation:
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?
- IntServ model with RSVP to support the traffic flows
- DiffServ model with PHB to support the traffic flows
- marking traffic at the access layer with DSCP to support the traffic flows
- marking traffic at the access layer with CoS to support the traffic flows
Correct answer: A
Explanation:

- BSR
- Auto-RP
- Static RP
Correct answer: B
Question 8
Which QoS feature responds to network congestion by dropping lower priority packets?
- CBWFQ
- tail drop
- WRED
- strict priority
Correct answer: C
Explanation:
Question 9
Which two BGP features will result in successful route exchanges between eBGP neighbors sharing the same AS number? (Choose two.)
- advertise-best-external
- bestpath as-path ignore
- client-to-client reflection
- as-override
- allow-as-in
Correct answer: DE
Question 10
A company is running BGP on a single router, which has two connections to the same ISP. Which BGP feature ensures traffic is load balanced across the two links to the ISP?
- Multihop
- Multipath Load Sharing
- Next-Hop Address Tracking
- AS-Path Prepending
Correct answer: B
