Cisco 300-420 Practice Test - Questions Answers, Page 11

Refer to the exhibit.

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.)

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)

Refer to the exhibit.

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 layer2 forwarding loops when the link fails. Which solution should the architect include?

Refer to the exhibit.

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?

Refer to the exhibit.

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?

Refer to the exhibit.

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?

A customer requests a VPN solution to connect multiple sites with the company headquarters. All the sites use the same IP subnet. The engineer plans to use VPLS. Which solutions must the engineer include in the design?

What is the purpose of a Cisco SD-Access underlay network?

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?
