Suggested Answer:
You set up disaster recovery for Azure VMs using Azure Site Recovery. Reference: https://docs.microsoft.com/en-us/azure/site-recovery/azure-to-azure-tutorial-enable-replication
The one with . at the end is fault tolerance. The one without . at the end is disaster recovery.
Look for . after virtual machines(.)
virtual machines. = fault tolerance
virtual machines = disaster recovery
correct answer.Disaster recovery is correct.

This article describes the architecture, components, and processes used when you deploy disaster recovery for Azure virtual machines (VMs) using the Azure Site Recovery service. With disaster recovery set up, Azure VMs continuously replicate to a different target region.
No, "fault tolerance" would not be the correct answer to fill in the blanks. Fault tolerance is a related concept, but it refers to a system's ability to continue operating without interruption in the presence of hardware or software failures. Azure Site Recovery is primarily focused on disaster recovery and ensuring that virtual machines can be quickly and reliably recovered in the event of a disaster or unexpected outage, rather than providing continuous fault tolerance.
the problem has a kind of error.

"Help your business to keep doing business—even during major IT outages. "
vs
"Site Recovery is a native disaster recovery as a service (DRaaS)"
[fault tolerence] and [disaster recovery] are in the explanation, simultaneously.
What am I supposed to do?
From my perspective, the primary feature of ASR is Disaster Recovery.
The definition of fault tolerance is slightly different. In my opinion, it can't be considered because of the replication model and the fact that it may change the hosting model (i.e. physical vs virtual).
Fault tolerance refers to a system's ability to continue operating properly in the event of the failure
Disaster recovery involves a set of policies, tools, and procedures to enable the recovery or continuation of vital technology infrastructure and systems following a disaster.
Azure Site Recovery is a service that helps ensure business continuity by keeping business applications and workloads running during outages.
Hence the answer is Fault tolerance
Question 50 and this question 81 are exactly the same question, yet with different answers.
The question remains: What does Azure Site Recovery provide for virtual machines?
Is it fault tolerance or disaster recovery? Or is it both?
Azure Site Recovery provides resilience and disaster recovery for apps and workloads running on on-premises machines, or Azure IaaS VMs. Site Recovery orchestrates replication, and handles failover to Azure when outages occur.
In short , as a final answer: Azure Site Recovery provides “disaster recovery” for VMs by creating backups, replicas, and redundant systems to minimize downtime and ensure business continuity
Azure Site Recovery offers a comprehensive solution for implementing and managing disaster recovery strategies, ensuring business continuity, and minimizing downtime in the face of unforeseen events.
Azure Site Recovery (ASR) provides disaster recovery as a service (DRaaS) by replicating virtual machines (VMs) and physical servers to Azure. This ensures business continuity and data protection in case of outages or disasters. ASR automates the replication, failover, and failback processes, offering flexibility and reliability for various scenarios.
Azure Site Recovery (ASR) is a disaster recovery service provided by Microsoft Azure that enables organizations to protect and recover their workloads running on-premises or in other cloud environments. ASR provides automated replication, failover, and failback of virtual machines, physical servers, and applications to Azure in the event of a site outage or disaster.
