A, B and C. ESXi 5.5 supports booting from an iSCSI SAN LUN with a supported iSCSI HBA, asupported dependent iSCSI hardware adapter, and the ESXi software iSCSI adapter.
- You create a new VMFS-5 datastore for one of your ESXi hosts. What is the largest VMDK file that can be created on this datastore?
A. 2 TB minus 512 bytes
B. 62TB
C. 64TB
D. None of these

- You have a costomer that requires that the target (storage system) authenticates the iSCSI adapter (initiator) and that the iSCSI adapter also authenticates the target. Which CHAP authentication method should be used?
A. One-way CHAP
B. Mutual CHAP
C. Thre-way CHAP
D. None of these
B. With Mutual CHAP, the target (storage system) authenticates the iSCSI adapter (initiator), and the iSCSI adapter also authenticates the target. This authentication method is also known as bidirectional.
- You have a customer that is deploying ESXi and will be using iSCSI storage. The customer wants the iSCSI implementation to use the least amount of the ESXi host resources as possible. Which of the following storage adapters would be the best choice for this set of requirements?
A. Software iSCSI adapter
B. Dependent hardware iSCSI adapter
C. Independent hardware iSCSI adapter
D. FCoE adapter
C. Since the independent hardware iSCSI adapter handles the workload for both the iSCSI processing and the iSCSI traffic, it would place the least amount of additional load on the ESXi host resources.

A. Provisioning
B. Zoning
C. LUN masking
D. Multipathing
C. LUN masking is a process performed at the SAN storage processors or ESXi host level that makes LUNs hidden from certain hosts.

A. 8MB
B. 4MB
C. 2MB
D. 1MB
A. VMFS-3 datastores will retain their original block size after an upgrade to VMFS-5.
- You need to unmounts a VMFS datastore from a cluster of ESXi hosts for maintenance. Which of the following are prerequisites for performing this action? (Choose all that apply.)
A. Virtual machines and templates may not reside on the datastore.
B. Mapping files for RDMs on the datastore must be removed.
C. ISOs located on the datastore must be removed from virtual machines.
D. The datastore must not be used for vSphere HA heartbeat.
A, B, C and D. All of these statemtnes are prerequisites for unmounting a VMFS datastore.
- Which of the following information is required when adding an NFS share to be used as a datastore? (Choose all that apply.)

C. NFS server credentials
D. NFS datastore name
A, B and D. The NFS server’s name, the IP address or NFS UUID, the path to the NFS share, and the NFS datastore name to be used in vSphere are all required when adding an NFS datastore.
- You have a two node cluster of ESXi 5.5 hosts managed by vCenter 5.5.

Which of the following can be used to provide the space for this file storage? (Choose all that apply.)
A. NFS
B. iSCSI
C. VMFS
D. RDM
C and D. A Fibre Channel SAN would allow you to use both VMFS and RDM to present these large volumes to the virtual machine.
- As part of routine maintenance, you unmounted an NFS datastore from an ESXi host. What do you need to do to mount this NFS datastore again, when the maintenance window is complete?
A. Reboot the ESXi host.
B. Right-click the inactive datastore and choose the Mount option from the context menu that appears.
C. Use the Add Storage Wizard to mount it.
D. Rescan the ESXi host’s HBAs.

- Which of the following storage adapters performs both the iSCSI processing and the networking for iSCSI traffic?
A. Software iSCSI adapter
B. Dependent hardware iSCSI adapter
C. Independent hardware iSCSI adapter
D. FCoE adapter

You create a VM with a single 50GB thin-provisioned virtual disk, and your storage array also uses thin provisioning. You later decide to protect this VM with VMware FT. How much space does this VM’s single virtual disk consume on the storage array?
A. Greater than 50GB
B. 50GB
C. Less than 50GB
D. It depends on the amount of data in the VMDK.
B. Vmware FT requires Thick Provision Eagerly Zeroed VMDKs. This means a 50GB VMDK will consume 50GB of space both at the VMDK level and at the storage array level.
- Which of the following is used to communicate information about iSCSI boot devices to an ESXi host.
A. iBHA
B. iBRP
C. iBDC
D. iBFT
D. iBFT (iSCSI Boot Firmware Table) is used to communicate information about the iSCSI boot device to an ESXi host.
- You have a 10-node ESXi cluster, and you just presented new devices to all 10 ESXi hosts. You need to quickly scan the adapters on all 10 hosts to find the new device. What option is the fastest?
A. In the vSphere Web Client, rescan each individual storage adapter for each ESXi host.
B. Write a script to perform this operation.
C. In the vSphere Web Client, use the Rescan Storage option from the context menu that appears when you right-click on the vCenter Server root object.
D. In the vSphere Client, use the Rescan Storage option from the context menu that appears when you right-click on the cluster object.
D. The Rescan Storage option from the context menu that appears when you right-click on the cluster object would scan all hosts in one operation. This would be the fastest option.
