Demo Questions

Question 1
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.
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.)
  1. support for AES 256-bit encryption
  2. greater scalability
  3. support for anycast gateway
  4. lower traffic overhead
  5. dynamic spoke-to-spoke tunnels
Correct answer: BE
Question 3
Which NETCONF operation creates filtering that is specific to the session notifications?
  1. <create-subscription>
  2. <commit>
  3. <notification>
  4. <logging>
Correct answer: A
Question 4
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?
  1. IntServ model with RSVP to support the traffic flows
  2. DiffServ model with PHB to support the traffic flows
  3. marking traffic at the access layer with DSCP to support the traffic flows
  4. marking traffic at the access layer with CoS to support the traffic flows
Correct answer: A
Question 5
Which nonproprietary mechanism can be used to automate rendezvous point distribution in a large PIM domain?
  1. Embedded RP
  2. BSR
  3. Auto-RP
  4. Static RP
Correct answer: B
Question 6
Which QoS feature responds to network congestion by dropping lower priority packets?
  1. CBWFQ
  2. tail drop
  3. WRED
  4. strict priority
Correct answer: C
Question 7
Which two BGP features will result in successful route exchanges between eBGP neighbors sharing the same AS number? (Choose two.)
  1. advertise-best-external
  2. bestpath as-path ignore
  3. client-to-client reflection
  4. as-override
  5. allow-as-in
Correct answer: DE
Question 8
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?
  1. Multihop
  2. Multipath Load Sharing
  3. Next-Hop Address Tracking
  4. AS-Path Prepending
Correct answer: B
Question 9
When a network is designed using IS-IS protocol, which two circuit types are supported? (Choose two.)
  1. nonbroadcast multiaccess
  2. multiaccess
  3. point-to-multipoint
  4. nonbroadcast
  5. point-to-point
Correct answer: BE
Question 10
What is an advantage of designing an out-of-band network management solution?
  1. In the event of a production network outage, network devices can still be managed.
  2. There is no separation between the production network and the management network.
  3. In the event of a production network outage, it can be used as a backup network path.
  4. It is less expensive than an in-band management solution
Correct answer: A
