Azure Site Recovery (ASR) is a service provided by Microsoft Azure that ensures business continuity by keeping business apps and workloads running during outages. ASR replicates workloads running on physical and virtual machines (VMs) from a primary site to a secondary location. When the primary site goes down due to a disaster, you can failover to the secondary location to keep apps and data available. After the primary location is restored, you can failback to it to resume operations.
Aspect | Description |
---|---|
Source Location | Azure region of the current VMs. |
Target Location | Azure region to which VMs will be replicated. |
Replication Policy | Defines RPO, retention, and test failover settings. |
Source VM Configuration | Includes the Azure VMs and associated configuration details. |
Target VM Configuration | Configuration of Azure VMs post-failover such as size, network. |
By following these steps, you can configure Azure Site Recovery (ASR) to ensure that your Azure resources remain available during disruptions, which is critical for maintaining high availability and business continuity. The configuration process can vary depending on your specific setup and needs, but the outlined steps offer a general guide for setting up ASR within the Azure environment. Make sure to conduct regular tests and drills to ensure that the failover process will work smoothly when an actual disaster occurs.
Explanation: Azure Site Recovery supports the replication of Azure VMs from one region to another, providing geographical redundancy.
Explanation: Azure Site Recovery can replicate workloads between Azure regions without requiring any on-premises infrastructure.
Answer: C) 5 minutes
Explanation: The minimum replication frequency for Azure VM replication using Azure Site Recovery is 5 minutes.
Explanation: Azure Site Recovery supports the replication of both standard and premium Managed Disks.
Answer: B) Recovery Services vault
Explanation: Azure Site Recovery requires a Recovery Services vault to manage replication, failover, and recovery of Azure VMs.
Explanation: Azure Site Recovery may have some restrictions based on regional availability, paired regions, and support for certain VM sizes.
Answer: A) 4 hours
Explanation: Azure Site Recovery aims for an RTO of less than 4 hours for Azure VMs during a failover event.
Answer: D) All of the above
Explanation: Azure Site Recovery supports test failovers, planned failovers, and unplanned failovers for comprehensive disaster recovery testing and execution.
Explanation: After you have initially set up replication, the target region for replication cannot be changed; you would need to set up a new replication if you wanted to change the target region.
Answer: B) Azure Activity Log
Explanation: Azure Activity Log provides auditing and can be used to ensure compliance with various requirements as it logs all the operations that occur in Azure Site Recovery.
Explanation: While Azure Site Recovery is primarily used for disaster recovery, it can also be used as a migration tool to move Azure VMs from one region to another.
Answer: D) Application-consistent
Explanation: Azure Site Recovery provides application-consistent replication, ensuring that not just the data but also in-memory processes and transactions are consistently replicated.
Azure Site Recovery is an Azure service that provides disaster recovery for workloads running on physical and virtual machines.
Azure Site Recovery provides protection against data loss, ensures business continuity, and reduces downtime by quickly recovering applications and services in case of a disaster.
Azure Site Recovery can help protect against disasters such as hardware failures, power outages, natural disasters, cyber attacks, and human errors.
Azure Site Recovery can protect Azure virtual machines, VMware virtual machines, and physical servers.
The prerequisites for setting up Azure Site Recovery for Azure virtual machines include an Azure subscription, a recovery services vault, a source Azure virtual network, and a target Azure virtual network.
The prerequisites for setting up Azure Site Recovery for VMware virtual machines include an Azure subscription, a recovery services vault, an on-premises configuration server, a process server, and a target Azure virtual network.
You can configure Azure Site Recovery for Azure virtual machines by creating a replication policy, selecting the source and target virtual networks, and enabling replication for the virtual machines.
You can configure Azure Site Recovery for VMware virtual machines by setting up the configuration server and process server, installing the Site Recovery Unified Setup, and configuring protection for the virtual machines.
The replication options for Azure Site Recovery include asynchronous replication, which provides low RPOs but may result in some data loss, and continuous replication, which provides zero RPOs but may require additional network bandwidth.
You can test your disaster recovery plan with Azure Site Recovery by creating a test failover, which allows you to verify the recovery process without impacting production workloads.
You can monitor the status of your replicated resources with Azure Site Recovery by using the Site Recovery Job Summary, Site Recovery Health, and Site Recovery Replicated Items views in the Azure portal.
Azure Site Recovery is billed based on the number of protected instances, the amount of storage used for replicated data, and the amount of data transferred during replication.
Yes, you can use Azure Site Recovery for cross-region replication to protect your workloads against regional outages and disasters.
The best practices for configuring Azure Site Recovery include creating a disaster recovery plan, testing your plan regularly, configuring monitoring and alerts, and optimizing your replication settings.
The RTOs for Azure Site Recovery depend on the replication options, network bandwidth, and size of the protected workload, but they typically range from a few minutes to a few hours.
