A VMware 5 customer is planning to upgrade their networking environment to 10 Gb
Ethernet. They would also like to use real time vMotion to ensure balanced application load distribution throughout their environment. They are also currently running their VMware environment on 64bit, dual core processors.
What advice would you give to your customer to assist them with the upgrade of their environment?

  • A. Upgrade their servers to quad core CPUs or greater and ensure all servers have access to the datastores.
  • B. Configure NIC teaming on their servers and ensure that all VMs on each ESXi server are configured for FT.
  • C. Ensure all servers have multiple paths to all arrays to support VM file movement and all VMs are configured for HA.
  • D. Ensure that all vMotion sessions are configured for core 0 (zero) affinity and enable Direct Path I/O.


Answer : A

A VMware Administrator has received numerous reports from his users about performance degradation. The administrator believes that your storage design on the VNX is the reason for the symptoms.
You ask the administrator for an esxtop analysis of the affected ESXi server. When you examine the report and notice that the value on the Load Average Line is 2.00.
What would you report back to the administrator?

  • A. The ESXi server is overloaded. The VMs should be redistributed or physical CPUs added.
  • B. The VM load is 2% of the total ESXi capacity. There is a different reason for the condition.
  • C. Each VM is only 2% loaded of their individual capacity. They are not the cause of the condition.
  • D. The ESXi CPU multiplier is set to 2, allowing each VM to have four vCPUs configured. Further investigation is required.

They have reviewed the analyzer file and told you that the NL-SAS disk queue length is 8.
What advice would you give them?

  • A. Consider upgrading their disk technology
  • B. No immediate changes are necessary
  • C. There is growth capacity for their environment
  • D. Modify the SCSI command set to optimize the queue utilization


Answer : A

Your customer is designing a Proof of Concept with SQL Server attached to a VNX. The storage design includes seven LUNs on a RAID Group. The system is generally very heavily loaded, with a particularly high load on the cache. This is a very carefully controlled environment and your customer has asked for assistance in planning the layout of the LUN location on the physical spindles.
Where in the RAID Group would you recommend placing the two heavily used LUNs if the physical spindle is fully utilized?

  • A. Adjacent to each other in the middle
  • B. One at beginning and one at the end
  • C. Adjacent to each other at the beginning
  • D. Evenly placed, as non-adjacent as possible
