Question No : 2
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)

Question No : 3
A solution architect has been tasked with designing a new environment that meets the needs of a growing company, and has obtained this information:
• The current capacity will be exhausted in 180 days, and the new infrastructure must be deployed and in production prior to that.
• The new servers have a 90-day delivery time.
• A data center for disaster recovery has been selected, and it is 20 miles away and connected by MPLS.
• The security team will continue to utilize its current investments and VM Encryption for the new environment.
• The backup team currently uses Data Domain, and reports show an 8:1 compression and deduplication ratio for backups.
Based on the information obtained, which two statements are risks for the new design? (Choose two.)

A.MPLS will be used to connect the two data centers.
B.The Change Advisory Board will approve all changes.
C.Current back up space will not be sufficient if using VM Encryption.

Question No : 5
A customer is virtualizing a mission-critical Microsoft SQL database and needs a configuration that provides optimal NUMA performance.
• There are two possible clusters that the database virtual machine could reside in: Cluster A is vSphere 6.0 and Cluster B is vSphere 6.5.
• All ESXi hosts contain dual Intel Xeon E5-2650 v3 processors (ie: 2 socket, 10 cores per socket) and 256Gb RAM with vNUMA in its default configuration.
Given this scenario, which three statements are true? (Choose three.)
A. Enabling CPU Hot Add on a virtual machine will disable vNUMA.
B. Placing a 10 vCPU VM in Cluster A and configuring it with 2 Sockets and 5 Cores Per Socket will result in 2 vNUMA nodes.
C. Placing a 10 vCPU VM in Cluster B and configuring it with 2 Sockets and 5 Cores Per Socket will result in 2 vNUMA nodes.
D. Enabling Memory Hot Add on a virtual machine will disable vNUMA.
E. Placing the VM in Cluster B and configuring it with 5 Sockets and 2 Cores Per Socket will result in 1 vNUMA node.

Question No : 6
An architect is designing a vSphere 6.5 implementation.
• The customer requires Cross vCenter vMotion for the newly-created data centers in New York and Houston.
• Each data center will use different IP networks for management and vMotion.

A.vMotion Networks in both data centers must be in the same L2 stretched VLA
B.The virtual machine port groups must use the same name.
C.VMkernel port for vMotion must be configured with vMotion TCP/IP Stack with the correct gateway.
D.vMotion networks in both data centers must be routable over L3 network.
