Q68. Which QoS feature responds to network congestion by dropping lower priority packets?

Q69. Refer to the exhibit.

Refer to the exhibit. AS65533 and AS65530 are announcing a partial Internet routing table as well as their IP subnets. An architect must create a design that ensures AS64512 become a transit AS. Which filtering solution must the architect choose?

Q70.

Refer to the exhibit. The distribution switches serve as the layer 3 boundary. HSRP preemption is enabled.
When the primary switch comes back after a failure, traffic is initially dropped. Which solution must be implemented to improve the design?

Q71. Which command is needed to enable DHCP snooping if a switchport is connected to a DHCP server?

Q72.

Refer to the exhibit. An engineer is designing an OSPF network for a client. Requirements dictate that the routers in Area 1 should receive all routes belonging to the network, including EIGRP, except the ones originated in the RIP domain. Which action should the engineer take?

Q73. Refer to the exhibit.

Refer to the exhibit. An architect reviews the low-level design of a company’s enterprise network and advises optimizing the STP convergence time. Which functionality must be to Gi1/0/1-10 to follow the architect’s recommendation?

Q74. An engineer is tasked with designing a dual BGP peering solution with a service provider. The design must meet these conditions:
* The routers will not learn any prefix with a subnet mask greater than /24.
* The routers will determine the routes to include in the routing table based on the length of the mask alone.
* The routers will make this selection regardless of the service provider configuration.
Which solution should the engineer include in the design?

Q75. Drag and drop the characteristics from the left onto the YANG modules they describe on the right. Not all options are used.

Q76. Which component of Cisco SD-Access integrates with Cisco DNA Center to perform policy segmentation and enforcement through the use of security group access control lists and security group tags?

Q77. How do endpoints inside an SD-Access network reach resources outside the fabric?

Q78. Refer to the exhibit.

Refer to the exhibit. A customer has two eBGP peerings from a single CE router toward two service providers. The customer has hired an architect to design a solution to ensure certain traffic enters the customer’s network through interface gig0/0. Which solution must the architect include in the design?

Q79. Drag and drop the properties from the left onto the protocols they describe on the right.

Q80. Refer to the exhibit.

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?

Q81. Refer to the exhibit. An engineer must design an automatic failover solution. The solution should allow HSRP to detect a WAN 1 failure and initiate an automatic failover, making router R2 the active HSRP router. Which two solutions should the engineer choose? (Choose two.)

Q82. A network engineer must design an MSDP multicast solution to provide RP resilience in a network with two separate domains. Also, multicast sources and receivers must register with the local RP. Which solution must the engineer choose?

Q83. Drag and drop the descriptions from the left onto the corresponding VPN types on the rights.

Q84. Refer to the exhibit.

An engineer is designing a routing solution for a customer. The design must ensure that a failure of network
10.1.0.0/24, 10.1.2.0/24, 10.2.1.0/24, or 10.2.3.0/24 does not impact the core. It also requires fast convergence time during any link failover in the core or access networks. Which solution must the engineer select?

Q85. An engineer must propose a solution for a campus network that includes the capability to create multiple Layer
3 virtual networks. Each network must have its own addressing structure and routing table for data forwarding.
The solution must be scalable to support hundreds of virtual networks and allow simple configuration and management with minimal administrative overhead. Which solution does the engineer recommend?

Q86. Drag and drop the model driven telemetry characteristics from the left onto the mode they belong to on the right.

Q87. A network solution is being designed for a company that connects to multiple Internet service providers. Which Cisco proprietary BGP path attribute will influence outbound traffic flow?

Q88. A network engineer must segregate three interconnected campus networks using IS-IS routing. A two-layer hierarchy must be used to support large routing domains and to avoid more specific routes from each campus network being advertised to other campus network routers automatically. Which two actions does the engineer take to accomplish this segregation? (Choose two.)

Q89. Refer to the exhibit.

An architect must design a solution to connect the network behind R3 with the EIGRP network. Which mechanism should be included to avoid routing loops?

Q90. Which control plane protocol is responsible for ElD-to-RLOC mapping concerning SO-Access Architecture?

Q91. Refer to the exhibit.

Refer to the exhibit A customer requires maximum uptime for the data plane between R1 and R3 running OSPF Which solution must the design include for high availability if the routing process on R2 requires maintenance?
