The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?  R1 has no route to R2 and drops the traffic  R1 load-balances across the paths through R3 and R4 to reach R2  R1 forwards the traffic to R3, but R3 drops the traffic  R1 forwards the traffic to R3 in order to reach R2 NO.22 Drag and drop the descriptions from the left onto the Cisco SD-WAN component they describe on the right. NO.23 Drag and drop the components in a Cisco SD-Access architecture from the left onto their descriptions on the right. NO.24 An architect must address sustained congestion on the access and distribution uplink of network. QoS has already been implemented and optimized, but it is no longer effective in ensuring optimal network performance. Which two solutions should the architect use to improver network performance. (Choose two)  Reconfigure QoS based on the IntServ model  Utilize random early detection to manage queues  Implement higher-speed uplink interfaces  Bundle additional uplinks into logical EtherChannels  Configure selective packet discard to drop noncritical network traffic. NO.25 Which method does Cisco SD-WAN use to avoid fragmentation issues?  PMTUD is used.  Traffic is marked with the DF bit set.  Jumbo frames are enabled.  Access circuits are configured with 1600 byte MTU settings. Explanationhttps://www.cisco.com/c/dam/en/us/solutions/collateral/enterprise-networks/sd-wan/nb-06-cisco-sd-wan-ebook-cNO.26 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?  Set the BGP Internet community for all prefixes.  Implement the NOPEER community.  Use the BGP No-Advertise community for the prefixes to exclude.  Attach the No-Export community with the prefixes to exclude NO.27 A global organization with several branches hired a network architect to design an overlay VPN solution. The branches communicate with each other frequently. The customer expects to add more branches in the future. To meet the customer’s security requirements, the architect plans to provide traffic protection using dynamic IPsec tunnels. Which solution should the architect choose?  DMVPN  EasyVPN  GETVPN  L2TP NO.28 A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?  Updates that contain changes within the data are sent only when changes occur.  Empty data subscriptions do not generate empty update notifications.  Periodic updates include a full copy of the data that is subscribed to.  The primary push update is sent immediately and cannot be delayed. ExplanationPeriodic updates contain a full copy of the subscribed data element or table for all supported transport protocolshttps://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/166/b_166_programmability_cg/model_dNO.29 Which consideration must be made when designing a Cisco SD-Access fabric underlay?  Subnets must be reduced to decrease latency.  Up to six control planes are supported.  The default MTU should be increased.  A unified policy must be used. NO.30 Which two statements about VRRP advertisements are true? (Choose two.)  They are sent from the master router and standby routers.  They include VRRP timer information.  They are sent only from the master router.  They include priority information.  They are sent every three seconds by default. NO.31 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 Section: Advanced Addressing and Routing SolutionsNO.32 Refer to the exhibit. A customer needs to apply QoS to the network management traffic passing through the GigabitEthernet0/2 interface. All eight queuing classes are in use, so the new requirement must be integrated into the existing policy. Which solution must the customer choose?  Mark traffic to DSCP CS5 and assign it to the SIGNALLING class. Then, baseline existing queue sizes to determine if additional bandwidth can be provisioned to the SIGNALLING class.  Mark the traffic to DSCP CS4 and assign it to the SIGNALLING class. Then, prioritize traffic within the class.  Mark the traffic to DSCP CS6 and assign it to the ROUTING class Then, prioritize traffic within the class.  Mark the traffic to DSCP CS2 and assign it to the ROUTING class Then, baseline existing queue sizes to determine if additional bandwidth can be provisioned to the ROUTING class NO.33 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:How must the solution prioritize the management traffic over the WAN?  Mark the traffic with DSCP CS1 and map into Class2 with a minimum bandwidth assigned by reducing the bandwidth available to CIass3.  Mark the traffic with DSCP CS6 and map into Class1 with a minimum bandwidth assigned by reducing the bandwidth available to Class2  Mark the traffic with DSCP EF and map into Class1 with a minimum bandwidth assigned by reducing the bandwidth available to Class2.  Mark the traffic with DSCP CS2 and map into Class2 with a minimum bandwidth assigned by reducing the bandwidth available to Class3 NO.34 An engineer is designing a multicast network for a company specializing in VoD content. Receivers are across the Internet, and for performance reasons, the multicast framework close to the receivers within each AS. For high availability, if the sources in one AS are no longer available, the receivers of that AS must be able to receive the VoD content from sources in another AS. Which feature must the design include?  Bidirectional PIM  SSM  Anycast RP  MSDP https://learningnetwork.cisco.com/s/question/0D53i00000KsrGrCAJ/rendezvous-point-high-availability-mechanismsNO.35 Refer to the exhibit.

NO.37 The customer solution requires QoS to support streaming multimedia over a WAN. An architect chooses to use Per-Hop Behavior. Which solution should the engineer use to of mark traffic traveling between branch sites?  LLQ with DSCP EF  CBWFQ with DSCP AF3  CBWFQ with DSCP AF2  LLQ with DSCP AF4 NO.38 A customer with an IPv4 only network topology wants to enable IPv6 connectivity while preserving the IPv4 topology services.

(Choose two.)  Use structured hierarchical topology with route summarization  Used sub-second timers  Use the distribute-list command to filter routes  Modify delay parameters on the links  Implement multiple EIGRP autonomous systems Section: Advanced Addressing and Routing SolutionsNO.41 Drag and drop the characteristics from the left onto the correct telemetry mode on the right. ExplanationIn a dial-in mode, the destination initiates a session to the router and subscribes to data to be streamed. Dialin mode is supported over gRPC in only 64-bit platforms In a dial-out mode, the router initiates a session to the destinations based on the subscription. All 64-bit IOS XR platforms (except for NCS 6000 series routers) support gRPC and TCP protocols. All 32-bit IOS XR platforms support only TCP.NO.42 Drag and drop the characteristics from the left onto the YANG modules they describe on the right. Not all options are used.

Which multicast protocol meets these requirements?  PIM-SM  PIM-SSM  any-source multicast  BIDIR-PIM NO.44 A large chain of stores currently uses MPLS-based T1 lines to connect their stores to their data center. An architect must design a new solution to improve availability and reduce costs while keeping these considerations in mind:* The company uses multicast to deliver training to the stores.* The company uses dynamic routing protocols and has implemented QoS.* To simplify deployments, tunnels should be created dynamically on the hub when additional stores open.Which solution should be included in this design?  VPLS  GET VPN  DMVPN  IPsec NO.45 When designing interdomain multicast, which two protocols are deployed to achieve communication between multicast sources and receivers?
