A systems architect has been asked to design the upgrade of a vSphere 5.5 to a 6.5 environment.
1.
The current vSphere environment has sites in Houston and New York, each with its own Single Sign-on domain.
2.
Each site also has a Windows vCenter Server
The business has requested these considerations during the upgrade design:
1.
One vSphere Single Sign-On domain
2.
vCenter Server configured in a highly available manner at each site
3.
reduce operating system licensing costs
4.
centralized repository for templates and ISOs
Which implementation order would satisfy these requirements?
A. Build out a new vSphere Single Sign-On domainDeploy a new Windows vCenter Server and use Microsoft ClusteringValidate from the VMware interoperability and third party matricesConfigure Content Library
B. Validate from the VMware interoperability and third party matricesUse the vSphere Migration Tool and enable vCenter High AvailabilityConsolidate the existing vSphere Single Sign-On domainConfigure Content Library
C. Validate from the VMware interoperability and third party matricesConsolidate the existing vSphere Single Sign-On domainUse the vSphere Migration Tool and enable vCenter High AvailabilityConfigure Content Library
D. Configure Content LibraryBuild out a new vSphere Single Sign-On domainValidate from the VMware interoperability and third party matricesDeploy a new Windows vCenter Server and use Microsoft Clustering
A company's security team requires that its enterprise certificate authority (CA) be used to sign all SSL certificates which encrypt network traffic. Which two design implementations will accomplish this for a vCenter Server Appliance 6.5?
A. Replace the Solution User certificates with an enterprise CA signed certificates
B. Replace the VMCA root certification with a subordinate certificate that has been issued by the enterprise CA, then re-generate all certificates from certificate manager
C. Upload the enterprise CA root certificate into the TRUSTED_ROOTS store and replace all certificates with Certificate Manager
D. Upload the enterprise CA root certificate into the TRUSTED_ROOTS store and replace just the Machine SSL certificate from Certificate Manager
E. Replace the Machine SSL and Solution User SSL certificates with enterprise CA signed certificates
Recommend in order to allow multicast snooping to enhance multicast performance in vSphere 6.5?
A. Change multicast filtering mode in distributed switch from basic to igmp/mld
B. Change multicast filtering mode in distributed switch from igmp/mld to basic
C. Edit query time interval for multicast snooping to 300 secs
D. Multicast is not supported.
A customer has requested that a new vSphere 6.5 environment be designed with its upcoming data center consolidation effort in mind.
1.
The existing environment is a mix of physical and virtual servers
2.
Fibre Channel storage is used for 100 vSphere ESXi hosts and 600 physical servers across three data centers, some of which contain latency sensitive applications critical to ongoing business
3.
The customer expects to increase its virtualization ratio from 50% today to 90% at the conclusion of this effort, and wants the new design to feature a software-defined storage solution that will decrease their TCO. Which two statements are the business requirements in this scenario? (Choose two.)
A. The design must include VMware vSAN as the primary storage solution
B. The design must account for business-critical applications
C. The design must increase virtualization adoption
D. The design must reuse wherever possible to reduce cost
A customer wants to upgrade the vSphere hosts in its development cluster to version 6.5.
1.
These hosts all utilize a vSphere 6.0 vSphere Distributed Switch (vDS)
2.
Due to hardware limitations, some of the hosts in the cluster must stay on version 6.0
Which procedure is supported while allowing the virtual machines to migrate between the two host versions?
A. Upgrade all the VMs to Virtual Machine Hardware v13
B. Upgrade to the Netwotk I/O control v3
C. Upgrade all the VMs to VMware Tools version 10.1
D. Upgrade the vSphere Distributed Swich to 6.5
A database administrator is operating a virtual machine (VM) configured with 16 vCPU and 64GB of RAM. A recent performance audit has indicated that this virtual machine is oversized and is using less than 60% of its configured CPU and memory capacity.
1.
The ESXi host that contains this VM has 2 physical processors with 10 cores per processor, and 128GB of RAM.
2.
This physical host's architecture is split into two equal NUMA nodes.
Which vCPU and RAM configuration for the VM allows for the most resources, but also provides the performance benefit of local NUMA access?
A. 16 vCPU and 32GB RAM
B. 4 vCPU and 16GB RAM
C. 10 vCPU and 64GB RAM
D. 12 vCPU and 64GB RAM
A management company has requested that a new vSphere 6.5 design be developed to protect its existing data center investment while it expands to a second data center site and introduces process automation.
1.
The existing environment consists of 32 vSphere 6.0 hosts attached to an iSCSI storage array containing external customer financial and medical records used by its investment and medical services divisions.
2.
The customer is also interested in the ability to expand to and failover to a public cloud. Which two valid assumptions can be made about the new design? (Choose two.)
A. The storage array is listed in the VMware Compatibility Guide (HCL/VCG) for vSphere 6.5. 12
B. The resulting design should utilize the existing hardware choices.
C. Sufficient power and cooling exists in the second data center.
D. Sufficient bandwidth exists between the sites for cross-cluster vMotion.
