Question #1
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
View answer
Correct Answer: A
Question #2
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

Correct Answer: B
Question #7
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 errors. Which 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

B. Fabric WLCs update the HTDB as new clients connect to the wireless network
C. Fabric APs update the HTDB with the clientsג€™ EID and RLOC
D. Fabric edge nodes update the HTDB based on CAPPWAP messaging from the AP
View answer
Correct Answer: B
Question #9
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
View answer
Correct Answer: C
Question #10
Company A recently acquired another company. Users of the newly acquired company must be able to access a server that exists on Company A's network, both companies use overlapping IP address ranges. Which action conserves IP address space and provides access to the server?
A. Use a single IP address to create overload NAT

C. Build one-to-one NAT translation for every user that needs access
D. Re-IP overlapping address space in the acquired company
View answer
Correct Answer: A
Question #11
