Refer to the exhibit. All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs. To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)
Drag and drop the properties from the left onto the Cisco SD-WAN components that perform them on the right.

A company with multiple service providers wants to speed up BGP convergence time in the event a failure occurs with their primary link. Which approach achieves this goal and does not impact router CPU utilization?
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 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?
