Final answer:
Companies can indeed increase the SLA guaranteed uptime by adding Azure resources to multiple regions, as this enhances redundancy and failover capabilities, thus ensuring higher service availability and uptime.
Step-by-step explanation:
The statement that companies can increase the Service Level Agreement (SLA) guaranteed uptime by adding Azure resources to multiple regions is True. When a company deploys resources across multiple regions in Azure, it provides a higher level of redundancy and failover capabilities. This geographical distribution of resources helps to ensure that if one region experiences downtime due to disasters or outages, other regions can take over, thereby maintaining the service availability as promised in the SLA.
For example, if a business has resources deployed in the East US region and adds additional resources in the West Europe region, the application can continue to function even if there is a major outage in one of those regions. This distribution aligns with the best practices for disaster recovery and business continuity planning, enabling a company to achieve higher uptime percentages and potentially negotiate better SLA terms with cloud service providers like Azure.
