What role does VMware Aria Operations play within a Cloud Management logical design?

An architect is planning an installation of VMware Aria Operations. Currently, the vSphere management cluster reports CPU contention which is not recommended for a VMware Aria Operations installation.
To mitigate any potential VMware Aria Operations performance issues, which two design decisions should be made? (Choose two.)

The lead architect for a teaching hospital in Seattle is planning the deployment of a highly-distributed Cloud Management Platform based on VMware vRealize Automation. The design must include log aggregation and analytics for in-depth troubleshooting and analysis when issues arise and ensure a seamless experience for the operations teams. The organization must use vRealize Log Insight for log aggregation and analysis.
The organization currently uses vRealize Operations for monitoring, alerting and capacity management.
The design will use external vRealize Orchestrator Appliances. Match the actions to the components.
Some of the components may be associated with more than one action.

An architect is responsible for creating the design for a Cloud Monitoring solution that will be used to monitor a greenfield VMware Software-Defined Data Center (SDDC).
During a requirements gathering workshop, the Service Owner provided a list of solution requirements:
- The solution must support a monthly availability target of 99.9%.
- The solution must support the monitoring of 1000 virtual machines across two data center locations.
- The solution must support the retention of live data for at least 12 months.
- The solution must be redundant to a minimum of N + 1 including during planned maintenance. The Recovery Time Objective (RTO) of solution is 4 hours.
Given the information from the Service Owner, which two statements would be considered functional requirements? (Choose two.)

Which of the following could be considered a risk in a Cloud Management logical design?
