If the metering tool supports multi-tenancy and integrates with the cloud portal, what should be considered?
A . Only permit local user access for security reasons
B . Metering tool should not integrate with tenant authentication
C . Metering server access should be allowed for all tenants
D . Role-based access for security reasons
Answer: D
Explanation:
The cost of collecting the metrics, and the balance between the value they provide and the impact on application operation. If metering code cannot be incorporated into existing components or roles, and you need to increase the number of instances of components or roles just to carry out metering, you might increase costs beyond the savings or income available from metering.
