An engineer is designing a Layer 3 campus network running EIGRP between the core, aggregation, and access layers. The access layer switches will be connected to the aggregation layer using Layer 3 copper connections. The engineer wants to improve the convergence time for access layer switch failures.Which technique must the design include?

A. enabling BFD for EIGRP on the access layer uplinks B. reducing the EIGRP Hello / Hold timer values C. EIGRP summarization from core to aggregation layer D. EIGRP summarization from access to aggregation layer

An existing network solution is using BFD in echo mode. Several network devices are experiencing high CPU utilization, which an engineer has determined is related to the BFD feature. Which solution should the engineer leverage to reduce the CPU load?

A. Implement slow timers between peers with low CPU resources. B. Implement BFD asynchronous mode between peers with low CPU resources. C. Enable BFD multi-hop on the devices with low CPU resources. D. Utilize carrier delay on all routers in the network.

How is a sub-second failure of a transport link detected in a Cisco SD-WAN network?

A. Hellos are sent between the WAN Edge routers and the vSmart controller. B. BFD runs on the IPsec tunnels between WAN Edge routers. C. BGP is used between WAN Edge routers and the vSmart controller. D. Link state change messages are sent between vSmart controllers.

Refer to the exhibit. Which two solutions maximize the use of the links between the core and distribution layers? (Choose two.)

A. use multiple equal-cost links B. use an IGP C. use HSRP D. use RPVSTP+ E. use multiple unequal-cost links

A customer's current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals: *reduce the impact of topology changes* reduce the time spent on network administration *reduce manual configuration errorsWhich two solutions should the architect include in the new design? (Choose two.)

A. Implement Rapid PVST+ instead of STP. B. Implement MST instead of STP. C. Use VTP to propagate VLAN information and to prune unused VLANs. D. Configure broadcast and multicast storm control on all switches. E. Configure dynamic trunking protocol to propagate VLAN information.

Which component is part of the Cisco SD-Access overlay architecture?

A. border node B. spine node C. leaf node D. Cisco DNA Center

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

A. Border nodes first register endpoints and then update the HTDB. B. Fabric WLCs update the HTDB as new clients connect to the wireless network. C. Fabric APs update the HTDB with the clients' EID and RLOC. D. Fabric edge nodes update the HTDB based on CAPPWAP messaging from the AP.

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

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?

A. Increase the hello timers on both HSRP devices. B. Use the preempt delay feature on the backup HSRP device. C. Use the preempt delay feature on the primary HSRP device. D. Configure a higher mac-refresh interval on both HSRP devices.
