An administrator is tasked with looking into the disaster recovery options for protecting a database server using VMware vSphere Replication.
The following requirements must be met:
The virtual machine must remain online during the protection.
The virtual machine's snapshots must be used as part of the replication process.
Which step must the administrator complete to accomplish this task?

  • A. Configure the virtual machine storage policy.
  • B. Enable guest OS VSS quiescing for this virtual machine.
  • C. Perform a full initial synchronization of the source virtual machine to the target location.
  • D. Configure network traffic isolation for vSphere Replication.

Guest OS VSS (Volume Shadow Copy Service) quiescing is essential for ensuring application-consistent backups of the virtual machine, especially when dealing with databases and other applications that rely on consistent disk states. When VSS quiescing is enabled, vSphere Replication coordinates with the guest operating system to create application-consistent snapshots, which are then used as part of the replication process. Enabling VSS quiescing helps ensure that the virtual machine remains online during the replication process and that the snapshots used for replication are consistent, minimizing the risk of data corruption and ensuring a more reliable disaster recovery solution. Options A, C, and D are not directly related to the specific requirements mentioned and do not address the need to maintain the virtual machine online during replication or utilize snapshots for the process.

Option A (Configure the virtual machine storage policy) is related to storage policies, which may not be directly tied to the requirements for guest OS VSS quiescing and replication. Option C (Perform a full initial synchronization of the source virtual machine to the target location) is a standard part of setting up vSphere Replication, but it does not specifically address the requirement for keeping the virtual machine online or using snapshots as part of the replication process. Option D (Configure network traffic isolation for vSphere Replication) refers to network configuration for vSphere Replication, but it is not directly related to meeting the stated requirements.

Selected Answer: C
Changing my answer to C. D is not required, but recommended. What is required is that a full initial synchronization must be done for a VM to be protected. Also VSS is not supported on all OS's. https://docs.vmware.com/en/vSphere-Replication/8.7/com.vmware.vsphere.replication-admin.doc/GUID-C249300C-2BC0-4128-88B5-046C3DE6BC5B.html

Agree. Point 16 says it all (Optional) Activate quiescing for the guest operating system of the source virtual machine. Note: Quiescing options are available only for virtual machines that support quiescing. vSphere Replication does not support VSS quiescing on vVOL.

C is incorrect as the initial sync is a prerequisite and has nothing to do with subsequent snapshots.

vSphere HTML5 client configures replication for a virtual machine. Replication for one or more virtual machines can be selected and configured via the same workflow. When configuring replication, an administrator specifies items such as the virtual machine storage policy, RPO, VSS or Linux file system quiescing, network compression and encryption of replication traffic. Virtual machine snapshots are not used as part of the replication process unless VSS quiescing is enabled.

Virtual machine snapshots are not used as part of the replication process unless VSS quiescing is enabled. <Check chapter Replication Process> https://core.vmware.com/resource/vsphere-replication-technical-overview#section3 The requirement in the questions says: The virtual machine's snapshots must be used as part of the replication process. How you can achieve that? Enabling VSS quiescing. Answer is B

Selected Answer: B
I choose B. Quiesce: If the flag is 1 or true, and the virtual machine is powered on when the snapshot is taken, VMware Tools is used to quiesce the file system in the virtual machine. Quiescing a file system is a process of bringing the on-disk data of a physical or virtual computer into a state suitable for backups. This process might include such operations as flushing dirty buffers from the operating system's in-memory cache to disk, or other higher-level application-specific tasks. Below article is the reason. https://kb.vmware.com/s/article/2041909 https://kb.vmware.com/s/article/1015180
