The Bottom Line

The Bottom Line

Cluster virtual machines with Microsoft Clustering Services (MSCS) Clustering virtual machines provides a means of creating an infrastructure that supports high availability for individual virtual machines.

Master It A critical network service requires minimal downtime. You need to design a failover solution for the virtual machine that hosts the network service. Your solution should provide the least amount of service outage while utilizing existing hardware and software platforms.

Implement and manage VMware High Availability (HA). VMware HA enabled on clusters of ESX Servers allows virtual machines from a failed ESX Server host to be restarted on another host. This feature offers reduced downtime and eliminates administrative effort as a response to a failed server situation.

Master It Domain controller, mail servers, and database servers must be the first virtual machines to restart in the event of server failure.

Master It In the event of server failure, you do not want virtual machines to be prevented from being powered on because of excessive resource contention.

Master It Virtual machines used for testing purposes should not be powered on by cluster nodes if they were running on the ESX Sever host that failed.

Master It Your virtual infrastructure includes redundancy at each level, including switches and NICs. Service Console ports, VMkernel ports, and virtual machine port groups exist on separate virtual switches. You need to ensure that virtual machines continue to run even if the Service Console loses network connectivity.

Back up virtual machines with VMware Consolidated Backup (VCB). VCB is a framework upon which third-party backup solutions can be constructed to perform full virtual machine and file-level backups. While the framework can be used on its own, it lacks any type of automation feature or the ability to write directly to tape.

Master It You need to design a data-recovery plan. The company purchased licenses for VMware Consolidated Backup. You must determine how VCB can accomplish your backup goals. What types of backups does VCB support?

Master It You need to implement VCB as part of a regularly scheduled backup job.

Restore virtual machines with VMware Consolidated Backup (VCB). The VCB framework encompasses not just the backup processes but also restore capabilities. Tools included with VCB allow backups of full virtual machines, individual VMDK files, or specific files from within the virtual machine operating system. In addition, VMware Enterprise Converter offers the simplest restore procedure with its support for restoring VCB backups.

Master It You need to minimize the financial impact of implementing a backup strategy for your virtual infrastructure.

Master It You need to minimize the amount of time required to restore data to any of the virtual machines in your environment.

Master It You have a full virtual machine backup of a system named Server1. A user deletes a file that is included on the last backup of Server1. You need to recover the file.

Master It You need to quickly restore a VCB backup of a virtual machine. The backup is stored in a shared folder named VMBackups on a server named Backup1. The name of the virtual machine is Server17.
