Suggested Answer:
Azure Site Recovery helps ensure business continuity by keeping business apps and workloads running during outages. Site Recovery replicates workloads running on physical and virtual machines (VMs) from a primary site to a secondary location. Reference: https://docs.microsoft.com/en-us/azure/site-recovery/site-recovery-overview
Disaster recovery is a whole replica of the data center set up and not just a single VM. IF a single VM has issues, fault tolerance should be able to cover for that downtime, hence Azure site recovery set up
Fault tolerance is correct.
Fault tolerance is a cloud service that remains *available after* a failure occurs.
Disaster Recovery is a cloud service that can be *recovered after* a failure occurs.
Azure Recovery Services contributes to your BCDR strategy:
Site Recovery service: Site Recovery helps ensure business continuity by keeping business apps and workloads running during outages. Site Recovery replicates workloads running on physical and virtual machines (VMs) from a primary site to a secondary location. When an outage occurs at your primary site, you fail over to secondary location, and access apps from there. After the primary location is running again, you can fail back to it.
Backup service: The Azure Backup service keeps your data safe and recoverable.
Taken from https://docs.microsoft.com/en-us/azure/site-recovery/site-recovery-overview
Fault Tolerant means service is available 'during' and 'after' the failure event. Azure Site Recovery will recover after the outage. Note the word 'recovery', means fault has occurred and you can recover. They talk about RTO and RPO.
Yes, right answer is Disaster Recovery, Azure provides the Azure Site Recovery (ASR) service as a key solution for Virtual Machines (VMs) under the broader "Azure Sites" or disaster
Disaster recovery is the recovery of a service after a failure. For example, restoring a virtual machine from backup after a virtual machine failure.

You can set up disaster recovery of Azure VMs from a primary region to a secondary region.
ans:disaster recovery
Site Recovery contributes to your business continuity and disaster recovery (BCDR) strategy, by orchestrating and automating replication of Azure VMs between regions, on-premises virtual machines and physical servers to Azure, and on-premises machines to a secondary datacenter.
Azure Site Recovery (ASR) is primarily a disaster recovery solution that helps organizations replicate and failover virtual machines (VMs) in case of an outage or failure. It ensures business continuity by allowing VMs to be recovered in a different Azure region or on-premises data center.
Disaster recovery is the correct answer.
Azure Site Recovery (ASR) is a disaster recovery (DR) solution that helps organizations replicate, failover, and recover workloads in case of an outage. It ensures business continuity by enabling recovery of virtual machines (VMs), applications, and services during unexpected failures.
Why not the other options?
Fault tolerance → Ensures continuous operation without failure, typically requiring redundant systems. ASR does not provide real-time fault tolerance.
Elasticity → Refers to the ability to scale resources dynamically, which is managed by Azure Autoscale, not ASR.
High availability → Ensures minimal downtime through redundancy but does not cover disaster recovery scenarios. Azure Availability Sets and Zones provide high availability.
So, Azure Site Recovery provides "disaster recovery" for virtual machines. ✅
Azure Site Recovery primarily provides disaster recovery for virtual machines. While it can contribute to high availability strategies, its core function is to replicate VMs to a secondary location (another Azure region or on-premises) so you can quickly recover them in the event of a primary site outage.
Disaster Recovery is the right answer.

Welcome to the Azure Site Recovery service! This article provides a quick service overview.
As an organization, you need to adopt a business continuity and disaster recovery (BCDR) strategy that keeps your data safe, and your apps and workloads online, when planned and unplanned outages occur.
Azure Recovery Services contributes to your BCDR strategy:
Azure Site Recovery (ASR) is a service designed to ensure business continuity and disaster recovery by replicating workloads running on virtual machines (VMs) to a secondary location. In the event of a failure or disaster, ASR enables failover to the secondary location, ensuring minimal downtime and data loss.
Other Options:
Fault Tolerance: ASR does not provide fault tolerance, as it does not ensure continuous operation of a system in the face of faults. Fault tolerance typically involves redundant systems that operate simultaneously.
Elasticity: Elasticity refers to the ability to scale resources up or down based on demand. ASR does not manage scaling; it focuses on disaster recovery.
High Availability: While ASR can contribute to availability during disasters, its primary function is disaster recovery, not ensuring high availability during normal operations.
Thus, Azure Site Recovery provides disaster recovery for virtual machines.
Site Recovery supports disaster recovery of on-premises VMware virtual machines.

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
It is designed to replicate workloads running on physical and virtual machines to a secondary location so that, in the event of an outage or disaster at the primary site, services can fail over to the secondary site and continue operating. This ensures business continuity and minimizes downtime during a disaster.
While fault tolerance is about preventing service interruptions (usually through redundancy), disaster recovery focuses on recovering services after an interruption has occurred, which is the primary function of Azure Site Recovery
The answer here should be "disaster recovery". Look up the docs link and ctrl+f, "'fault tolerance'' does not even exist on that page. Therefore the answer is "disaster recovery".
This question is appearing two times with different options.
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
wow did this really need 400 comments when clearly the doc states it is a disaster recovery service and the words fault tolerance aren’t even mentioned
