A company wants to implement a public IaaS solution but also wants to address site resiliency challenges. When selecting an IaaS provider, which of the following should a cloud technician look for…

Bare metal service refers to provisioning physical servers without a hypervisor layer and does not address the resiliency of the network connection between the company's physical site and the cloud.

Failure zones protect against datacenter-level failures within the cloud itself, but do not address the resiliency of the WAN link between the company's on-premises site and the IaaS provider.

Backup services protect against data loss and support recovery objectives but do not ensure that the company's site can maintain continuous, resilient connectivity to its IaaS resources.

Dedicated connectivity solutions such as AWS Direct Connect or Azure ExpressRoute establish a private, consistent circuit between the company's site and the IaaS provider. This directly addresses site resiliency by ensuring connectivity to cloud resources is not subject to public internet outages or congestion, providing a high-availability, predictable link that keeps the site operational even during internet disruptions.
