7 SDDC Business Continuity

Question 1

High Availability

Answer 1

• Redundant components: If a network interface card (NIC) on a server fails, a second NIC prevents loss of network connectivity.
• Processes and services remain continuously operational for extended lengths of time.

Question 2

Disaster Recovery

Answer 2

• Backup components: If the virtual disk of a VM becomes corrupt, you rebuild the VM from a backup.
• A disaster interrupts the processes or services, and you must restore them.

Question 3

Which VMware solutions does VMBeans use for disaster recovery and which for high availability?

Answer 3

• Using vSphere Replication, you replicate VMs as part of your backup and recovery strategy = Disaster Recovery
• You use vSphere vMotion to move a powered-on VM from one ESXi host to another when performing maintenance on the host = High Availability
• You use multiple NICs in NIC teaming to protect from a component failure = High Availability
• Using vSphere Storage vMotion, you can move the files of a powered-on VM from one storage device to another while you upgrade storage = High Availability
• Using Site Recovery Manager, you can perform a data center migration to a new facility = Disaster Recovery
