300-420 Practice Test practice questions, page 15 of 17, with answer review and explanations.
Question 71
Refer to the exhibit. Where must an architect plan for route summarization for the topology?
from the core toward the aggregation and the access toward the aggregation
from the core toward the aggregation and the aggregation toward the core
from the aggregation toward the access and the access toward the aggregation
from the aggregation toward the core and the aggregation toward the access
Question 72
Refer to the exhibit. The connection between SW2 and SW3 is fiber and occasionally experiences unidirectional link failure. An architect must optimize the network to reduce the change of Layer 2 forwarding loops when the link fails. Which solution should the architect include?
Utilize BPDU filter on SW3.
Utilize root guard on SW1.
Utilize BPDU guard on SW1.
Utilize loop guard on SW2.
Question 73
Refer to the exhibit. The full EIGRP routing table is advertised throughout the network. Currently, users experience data loss when any one link in the network fails. An architect must optimize the network to reduce the impact when a link fails. Which solution should the architect include in the design?
Run BFD on the inter links between EIGRP neighbors.
Summarize the access layer networks from each access layer switch toward the aggregation layer.
Reduce the default EIGRP hello interval and hold time.
Summarize the access layer networks from the aggregation layer toward the core layer.
Question 74
What is the purpose of a control plane node in a Cisco SD-Access network fabric?
to maintain the endpoint database and mapping between endpoints and edge nodes
to detect endpoints in the fabric and inform the host tracking database of EID-to-fabric-edge node bindings
to identify and authenticate endpoints within the network fabric
to act as the network gateway between the network fabric and outside networks
Question 75
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 applied to Gi1/0/1-10 to follow the architect's recommendation?
