  Which backup WAN link type the engineer recommend?

  A. LTE

  B. 802.16 WiMAX

  C. Laser link

  D. 802.15.1 Bluetooth

  Correct Answer: A

• Question 112:

  An engineer uses Postman and YANG to configure a router with:

  1.

  OSPF process ID 100

  2.

  network 10.10.10.0/28 enabled for Area 0

  Which get-config replay verifies that the model set was designed correctly?

  

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: B

• Question 113:

  A company must automate a set of complex changes aligned with DR testing in the network. These changes are specific, and the DR playbook will be adjusted in the future. The playbook has diverse routing and switching assets in scope as well as multiple vendor and hardware platforms. A developer will create a thin, web front-end microservice and integrate with an Open daylight controller to push changes to the network. Which YANG model should be used?

  A. Use a single native vendor YANG model to minimize development time

  B. Use an open YANG model to allow the reuse of code and standardize the implementation across platforms

  C. Use multiple native vendor YANG models to provide code consistency.

  D. Develop an individualized YANG model to minimize development resources and time to market.

  Correct Answer: B

• Question 114:

  What is the purpose of a control plane node in a Cisco SD-Access network fabric?

  A. to maintain the endpoint database and mapping between endpoints and edge nodes

  B. to detect endpoints in the fabric and inform the host tracking database of EID-to-fabric-edge node bindings

  C. to identify and authenticate endpoints within the network fabric

  D. to act as the network gateway between the network fabric and outside networks

• Question 115:

  How are wireless endpoints registered in the HTDB in a Cisco SD-Access architecture?

  A. Fabric edge nodes update the HTDB based on CAPPWAP messaging from the AP

  B. Fabric WLCs update the HTDB as new clients connect to the wireless network

  C. Border nodes first register endpoints and then update the HTDB

  D. Fabric APs update the HTDB with the clients' ElD and RLOC

  Correct Answer: B

• Question 116:

  Which type of rendezvous point deployment is standards-based and support dynamic RP discovery?

  A. Auto-RP

  B. Anycast-RP

  C. bootstrap router

  D. static RP

  Correct Answer: C

• Question 117:

  An engineer must design an in-band management solution for a customer with branch sites. The solution must allow remote management of the branch sites using management protocols over an MPLS WAN. Queueing is implemented at the remote sites using these classes:

  1.

  Class1 equals voice traffic

  2.

  Class2 equals mission-critical traffic

  3.

  Class3 equals default traffic

  How must the solution prioritize the management traffic over the WAN?

  A. Mark the traffic with DSCP CS1 and map into Class2 with a minimum bandwidth assigned by reducing the bandwidth available to CIass3.

  B. Mark the traffic with DSCP CS6 and map into Class1 with a minimum bandwidth assigned by reducing the bandwidth available to Class2

  C. Mark the traffic with DSCP EF and map into Class1 with a minimum bandwidth assigned by reducing the bandwidth available to Class2.

  D. Mark the traffic with DSCP CS2 and map into Class2 with a minimum bandwidth assigned by reducing the bandwidth available to Class3

  Correct Answer: D

• Question 118:

  Refer to the exhibit. An architect is designing a BGP solution to connect a remote branch to a service provider. There are several prefixes within the branch that the company does not want to be advertised to the internet. Which solution should the architect use to accomplish this?

  

  A. Set the BGP Internet community for all prefixes.

  B. Implement the NOPEER community.

  C. Use the BGP No-Advertise community for the prefixes to exclude.

  D. Attach the No-Export community with the prefixes to exclude

  Correct Answer: D

• Question 119:

  A customer requests a VPN solution to connect multiple sites with the company headquarters. All the sites use the same IP subnet. The engineer plans to use VPLS. Which solutions must the engineer include in the design?

  A. 802.1Q connectivity on the LAN side of the CE

  B. route exchange with the service provider

  C. address translation to hide overlapping subnets

  D. different VLANs on each site

  Correct Answer: A

• Question 120:

  What is the purpose of a Cisco SD-Access underlay network?

  A. to abstract IP-based connectivity from physical connectivity

  B. to emulate LAN segments to transport Layer 2 frames over a Layer 3 network

  C. to establish physical connectivity between switches and routers

  D. to provide virtualization by encapsulating network traffic over IP tunnels

  Correct Answer: C
