Question: 149


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: AE


Question: 150


Which design consideration should be observed when EIGRP is configured on Data Center switches?

  1. Perform manual summarization on all Layer 3 interfaces to minimize the size of the routing table.

  2. Prevent unnecessary EIGRP neighborships from forming across switch virtual interfaces.

  3. Lower EIGRP hello and hold timers to their minimum settings to ensure rapid route reconvergence.

  4. Configure multiple EIGRP autonomous systems to segment Data Center services and applications.


Answer: A


Question: 151


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: B


Question: 152


Which NETCONF operation creates filtering that is specific to the session notifications?

  1. <create-subscription>

  2. <commit>

  3. <notification>

  4. <logging>


Answer: A


Question: 153


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


Answer: B


Question: 154


Which QoS feature responds to network congestion by dropping lower priority packets?

  1. CBWFQ

  2. tail drop

  3. WRED

  4. strict priority


Answer: C


Question: 155


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


Answer: A


Question: 156


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

Answer: A


Question: 157


Which function are fabric intermediate nodes responsible for in an SD-Access Architecture?

  1. mapping EIDs to RLOCs

  2. encapsulating user traffic in a VXLAN header including the SGT

  3. registering new endpoints in the HTDB

  4. transporting IP packets between edge nodes and border nodes


Answer: D


Question: 158

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


Answer: B
