VMware Data Center Virtualization Fundamentals — Question 30

An IT administrator working in a space agency has just in installed some applications that are critical for a satellite launch mission. The administrator wants the applications to work irrespective of any operating system failure.
Which vSphere 6.x feature should the administrator use?

Answer options

• A. vSphere HA
• B. vSphere Fault Tolerance
• C. vSphere Replication
• D. vSphere Data Protection

Correct answer: B

Explanation

The correct answer is B, vSphere Fault Tolerance, as it provides continuous availability for applications by creating a live shadow instance that runs simultaneously with the primary VM, ensuring no downtime during OS failures. Option A, vSphere HA, is designed for failover of virtual machines but does not guarantee zero downtime. Options C and D, vSphere Replication and vSphere Data Protection, respectively, focus on data backup and recovery rather than real-time application availability.
