New VTSP Dumps


Q: You are deciding on the datastores to be used for a storage solution and have to choose whether to allocate isolated or consolidated storage for the virtual machines. You have decided on a consolidated storage design for most virtual machines and need to identify the virtual machines that might be more suitable for isolated storage. Which of the following would be good reasons for specifying isolated storage for a virtual machine? Choose two. A: The VM runs a mission critical heavy I/O workload The VM requires direct access to its storage hardware The VM will require more than 2TB of virtual storage The VM does not need to be protected by vSphere HA Q: Your customer has an existing multi-protocol SAN that supports both Fibre Channel (FC) and iSCSI storage networks. Their existing vSphere ESXi cluster uses FC for all shared storage but the SAN is configured to provide iSCSI storage to a number of other systems. The customer wants to extend their vSphere cluster but due to the cost of the FC HBA’s and switch upgrades that would be required has specified that the new ESXi hosts must be configured to use iSCSI storage. How will this impact the design and features of the new vSphere environment? Choose one.

A: vSphere cannot access the same storage through different protocols so the new ESXi hosts cannot be configured with iSCSI storage. vSphere cannot access the same storage through different protocols so the new ESXi hosts will have to be in separate HA clusters vSphere can access the same storage through different protocols so the new ESXi hosts can be configured with iSCSI storage vSphere can access the same storage through different protocols provided the ESXi hosts are configured with converged HBA’s Q: When analyzing the capacity planning reports for a new virtualization project the initial storage analysis suggests that you will need approximately 300 x 250 GB VMFS volumes in the customer’s vSphere 5.5 cluster. This is based on the number of virtual machines and the customer’s request that each virtual machine be mapped to a single VMFS datastore. What specific problem does this cause and what should you recommend to the customer to resolve it? Choose one. A:

vSphere 5.5 supports a maximum of 256 VMFS volumes per ESXi host, some virtual machines will have to be provisioned on shared VMFS datastores vSphere 5.5 supports a maximum of 64 VMFS volumes per ESXi host, most virtual machines will have to be provisioned on shared VMFS datastores vSphere 5.5 supports a maximum of 64TB of VMFS storage per ESXi host, some VMFS datastores will have to be reduced in size vSphere 5.5 supports a maximum of 256 VMFS datastores per ESXi host by default, that limit must be increased on each ESXi host

Q: You are finishing your storage design for additional capacity on a customer’s vSphere 5.5 cluster and need to finalize the requests for storage capacity from the SAN Administration team. Your design uses 3 x 250GB VMFS datastores that need to be hosted on high performance storage and 3 x 250GB VMFS datastores that do not require high performance storage but which must be kept on separate physical storage for security reasons. Which of the following LUN requests should you make to the storage team? Choose one.

A: 3 x 250GB Tier 1 LUNs and 3 x 250GB Tier 2 LUNs 1 x 750GB Tier 1 LUN and 3 x 250GB Tier 2 LUNs 1 x 750GB Tier 1 LUN and 1 x 750GB Tier 2 LUN 3 x 250GB Tier 1 LUNs and 1 x 250GB Tier 2 LUN Q: vSphere VMFS datastores can be configured using thin provisioned SAN volumes. Virtual Machines can crash if they are stored on a thin provisioned SAN volume that runs out of spare capacity while the VM is attempting to write new data. Which SAN hardware feature allows vSphere 5.5 to address this problem in a more controlled manner? Choose two. A: VAAI – VM Stun primitive VASA – VM Stun primitive VAAI – VM Shutdown primitive VASA – VM Shutdown primitive Q: Your customer has said that they would like to use the vCenter Appliance and the VSA in their new vSphere 5.5 environment. Which of the following constraints apply to running vCenter on the VSA? Choose one. A: vCenter can run on the VSA but it must be installed in a local datastore first Running vCenter on the VSA is supported but only in a 2 node VSA cluster

vCenter can run on the VSA but only if it is directly installed in a VSA datastore Running vCenter on the VSA is only supported for test and lab environments

Q: Which of the following types of virtual machines should not, or cannot, be configured to use Thin Provisioned virtual disks? Choose two.

A: A VM that will be protected using vSphere Fault Tolerance A VM that will be protected using vSphere High Availability A high performance VM that requires consistent disk performance A VM that will be configured with a large disk that will initially be empty Q: Your customer has a large NAS infrastructure that provides all of the virtual storage capacity for their vSphere 5.5 environment. They have been expanding capacity recently and have reported that they are unable to access one of two new NFS v3 NAS share that they have just added. What is the most likely root cause and what should they do to resolve this issue? Choose one. A: vSphere 5.5 supports only 8 NFS Datastores by default, that limit must be increased in order to be able to mount both the new datastores vSphere 5.5 can only support 8 v3 NFS v3 Datastores concurrently, their new storage must support NFS v4. Create an extended NFS Datastore using the second NFS v3 mount as a volume extent. vSphere 5.5 supports a maximum of 8 NFS Datastores, they should reconfigure the NAS storage to combine the underlying storage on the array. Q: Which of the following are specific disadvantages of an isolated storage design where each virtual machine is mapped to a single LUN? Choose two. A: The design has poor scalability and will quickly reach the upper limit of 256 LUNS and VMFS volumes per ESXi Host Storage DRS cannot be used to ensure that storage resources are dynamically allocated in response to utilization needs vSphere HA and vSphere Fault Tolerance cannot be used for virtual machines that use isolated storage. You will be unable to use RDM disks as the RDM mapping file must be stored on a consolidated VMFS datastore.

Q:

During the site survey for a new vSphere 5.5 migration project you find that the customer has a series of application servers that are currently configured with 32 separate physical disks. The customer has said that they wish to retain this underlying structure during the migration rather than consolidate these into a smaller number of disks. How can the virtual machine storage for these VMs be configured to support this? Choose one.

A: Three virtual SCSI Controllers of any type Three virtual Paravirtualized SCSI Controllers Three virtual LSI Logic SAS SCSI Controllers Three virtual BusLogic SCSI Controllers Q: Your customer uses hardware based thin provisioning on their SAN for VMFS datastores that store Windows virtual machines and is very interested in the new Space Efficient Sparse Disk VMDK format that is supported by vSphere 5.5. The customer wants to test SE Sparse disks for some new Windows Server 2008 VMs in order to compare it with the SAN hardware solution. What pre-requisite for SE Sparse disks in vSphere 5.5 prevents them doing this in their current environment? Choose one. A: SE Sparse Disk format can only be used VMware View 5.1 and Horizon View 5.x SE Sparse Disk format is only compatible with Virtual Machines running Linux SE Sparse Disk format requires that the VMDKs are stored on NFS Datastores SE Sparse Disk format is only configurable for Windows Desktop Virtual Machines Q: In order to ensure that Storage I/O resources are allocated fairly amongst a set of virtual machines, your customer has enabled Storage I/O control. However they are concerned that one virtual machine appears to be using more resources than the other virtual machines and is not respecting the behaviour they anticipated when using SIOC. Which of the following could be a possible cause of the issue? Choose two. A: The virtual machine is located on fibre channel storage The virtual machine has raw device mappings The datastore is made up of multiple extents Storage I/ O control is not enabled on the server Q: In vSphere 5.5 which mechanism must be used to allow multiple iSCSI paths between the software iSCSI adapter on an ESXi server and iSCSI targets? Choose one. A:

Port Binding NIC teaming SCSI Reservations Dynamic discovery Q: The storage I/O path provides virtual machines with access to storage devices. How does it achieve this? Choose one. A: Through device emulation Through paravirtualization Through guest emulation Through kernel emulation

Q: vSphere 5.5 virtual machines can be configured to use SCSI attached disks. These virtual disks can be provisioned in which two of the following ways? Choose two.

A: As VMDK format files on VMFS or NFS Datastores As block storage using a Raw Device Mapping (RDM) As VMDK formatted local or SAN attached SCSI disks As local, SAN attached or NAS VMFS disks Q: What is the maximum number of ESXi hosts that be connected concurrently to a single VMFS-5 volume? Choose one.

A: 8 64 128

256

Q: You customer reports the storage solution they implemented is not responding to path failures as they would have anticipated. Analysis shows that the correct path to the storage is not being selected even though it is visible. Which component is the most likely cause of the behavior? Choose one.

A: The third party PSP is not installed correctly The Host Bus Adapter drivers are not installed correctly The VMware PSP is not installed correctly The third party NMP is not installed correctly

Q: You are allocating storage in a new environment and need to decide how much free capacity you leave unallocated in each datastore once all virtual machines have been provisioned. You know that snapshots will rarely be used in this environment. Choose one.

A: 40-50% 10-20% 20-30% 0-10% Q: After analyzing the storage requirements for a new vSphere 5.5 environment you have found that the total capacity required for the solution will be approximately 30TB. You have decided to install the vSphere Storage Appliance using 3 ESXi hosts with 8 x 3TB disks as the storage solution for this environment. How much usable capacity will the VSA be able to present across this environment? Choose one. A: 72TB 48TB

27TB 18TB Q: When discussing the initial design requirements for a new vSphere 5.5 environment with a customer they have expressed doubts about the viability of iSCSI as they believe that a 1Gb/sec Ethernet network cannot be as good as a 4Gb/sec or even 8Gb/sec FC network. Which two of the following are technologies that are supported by vSphere enable high performance iSCSI solutions? Choose two. A: 10Gb/sec Ethernet iSCSI multi-pathing NIC Teaming Fibre Channel over Ethernet Q: When discussing your proposed vSphere 5.5 solution with a customer they have questioned the need for shared storage since enhanced vMotion in vSphere 5.5 enables live migration between hosts without requiring shared storage. Which of the following vSphere features would have to be removed from a vSphere design if it did not include shared storage? Choose one. A: vSphere High Availability vSphere Host Profiles vSphere Auto Deploy vSphere Storage vMotion Q: When discussing the proposed storage design for your customer’s new vSphere 5.5 infrastructure they have stated that they have a pre-existing NAS that they would prefer to use. Which of the following recommendations should you make as part of validating the suitability of this storage solution? Choose one. A: Check that the NAS is on the vSphere Hardware Compatibility List (HCL) Check that the NAS supports NFS v3 and the RAID types required in your design. Check the NAS supports both NFS v3 and iSCSI protocols Ensure that your ESXi host specification includes HBA’s that are compatible with this NAS
