- D . The current firewalls will support the additional workloads.
The hardware operations team is planning to purchase new ESXi hosts for the upcoming budget year and is requesting recommendations on the type of servers to purchase for a web application. The web application consists of hundreds of small virtual machines (1 vCPU and 8GB of RAM) that are members of a software cluster.
The solution should have these abilities:
• recover from ESXi host hardware failures
• zero downtime for a limited number of critical virtual machines (VMs)
• migrate running VMs between ESXi hosts without interruption to the operating system
• perform these functions using VMware ESXi servers, vCenter Server, and high-speed network interfaces
What are the three functional requirements and their associated VMware technologies? (Choose three.)
- A . automatic restarts of failed VMs (vSphere HA)
- B . high speed network interfaces (vSphere Distributed Switches)
- C . ability to migrate running VMs (vSphere vMotion)
- D . fault tolerance for limited number of critical VMs (vSphere FT)
- E . VMware ESXi Servers (vSphere Auto Deploy)
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?
- 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
