VMware vSphere 6 Advanced Design (VCAP6-DCV Design) — Question 26

A company is designing a new vSphere cluster to support a mission-critical application.
✑ The application requires 100% availability and cannot be restarted to recover from an ESXi host failure.
✑ The application consists of a group of 16 virtual machines, each with 8 vCPU configured.
Which solution satisfies the availability requirements?

Answer options

• A. Guest OS-based software clustering
• B. vSphere High Availability
• C. vSphere High Availability Application Monitoring
• D. vSphere Fault Tolerance
• E. vSphere Site Recovery Manager

Correct answer: D

Explanation

The correct answer is D, vSphere Fault Tolerance, as it provides continuous availability for virtual machines by creating a live shadow instance that can take over instantly without any downtime. The other options, while useful for different scenarios, do not ensure 100% availability for applications that cannot tolerate any interruption, such as software clustering (A), High Availability (B), or Application Monitoring (C), and Site Recovery Manager (E) focuses on disaster recovery rather than continuous operation.
