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?

A.

Utilize 8PDU filter on SW3.

B.

Utilize loop guard on SW2

C.

Utilize BPDU guard on SW1

D.

Utilize root guard on SW1.

DHCP options or manual configuration

B.

vManage or DNS records

C.

ZTP or manual configuration

D.

DNS records or DHCP options

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

A.

C.

Border nodes first register endpoints and then update the HTDB

D.

Fabric APs update the HTDB with the clients' ElD and RLOC

A company uses cloud-based applications for voice and video calls, file sharing, content sharing, and messaging. During business hours, these applications randomly become slow and unresponsive. However, other applications work smoothly with the current applied QoS polices. Which solution must the company choose to resolve the issue?

A.

Identify the applications with NBAR2 and allocate the required bandwidth accordingly.

B.

Identify the port used by each application and apply a minimum bandwidth guarantee.

C.

Identify the applications and reserve the required bandwidth on the perimeter routers.

D.

Identify the application ports, create groupings, and rate-limit the required bandwidth.

Refer to the exhibit An engineer is designing an OSPF solution with these requirements:

    NMS server will manage R5 and R6.

    Upon failure of R1. all NMS traffic should be routed through R4.

    Upon failure of the link between R5 and R6. all traffic destined for 10.6.6.6 should be routed through R4

Which solution must the engineer choose?

A.

Advertise 172.16.1.1 into OSPF process 1 with high cost on R1.

B.

Apply static routes on R2 and R3 with IP SLA tracking toward R5 and R6.

C.

Enable the default-Information originate command with a higher metric on R2 to R1.

D.

Redistribute OSPF process 1 into process 2 on R1 and R4.
