Which action would mitigate the issue? An administrator is upgrading a vCenter Server Appliance and wants to ensure that all the prerequisites are met. What action must be taken before upgrading the vCenter Server Appliance? What is the compression algorithm used by vSphere Replication to compress data at the source? An administrator is unable to upgrade a vCenter Server Appliance from version 5.1 Update 2 to version 6.0. What is a likely reason for this? Which group in the vsphere.local domain will have administrator privileges for the VMware Certificate Authority (VMCA)? Which two features are deprecated in Network I/O Control 3 (NIOC3)? (Choose two.) What command line utility can be used to upgrade an ESXi host? An administrator is deploying ESXi 6.x hosts using Auto Deploy and wants the image profile to be available, even after closing and opening a new PowerCLI window. Which command can be used to ensure that image profiles are preserved across PowerCLI sessions? An administrator is troubleshooting a performance problem with a virtual machine (VM). The VM and ESXi host configuration is as follows: The administrator would like to improve CPU performance for this VM. Other VMs on the host have no performance issues. Which action should the administrator take to resolve the issue? Users are reporting CPU related performance problems on the virtual machine Email-Prod throughout the day. The resource settings for the VM and the ESXi host the VM is running on are shown below: VM: ESXi host: Which two options would alleviate the observed performance problem for Email-Prod?

An administrator has decided to create 10 ESXi 6.x hosts via Auto Deploy for a new Test/Dev cluster. The hosts are configured to obtain their networking configuration via DHCP. Which Direct Console User Interface option should the administrator use to renew the DHCP lease for the hosts? Which three components should an administrator select when configuring vSphere permissions? (Choose three.) An administrator is having a problem configuring Storage I/O Control on a Datastore. Which two conditions could explain the issue? (Choose two.) What is the minimum Virtual Hardware version required for vFlash Read Cache? Which two reasons would prevent Storage Distributed Resource Scheduler (SDRS) from operating on a datastore? (Choose two.) The command esxcli network vm list displays four virtual machines connected to the Production vSwitch. Within the vSphere Web Client, five virtual machines are seen. What explains this behavior? An administrator notices that a Windows virtual machine is using 95% CPU in Task Manager. Which two actions should be taken to resolve this issue? (Choose two.) What three supported methods can be used to upgrade a host from ESXi 5.x to ESXi 6.x? (Choose three.) An administrator is configuring virtual machines to use Worldwide Port Names (WWPNs) to access the storage. Which two conditions are required? (Choose two.) Which two statements are true regarding Virtual SAN Fault Domains? (Choose two.) Deletion of an NFS datastore generates the following error: Sysinfo error on operation returned the following status: Busy Which step can be performed that will allow the deletion to complete successfully? An administrator tries to run esxtop to troubleshoot CPU performance issues, but no output is displayed. How can the issue be resolved? An administrator uses the df -h command and notices that an NFS datastore is reporting a capacity of 0 Bytes. What condition would cause this to occur? An administrator created a six node Virtual SAN cluster, created a fault domain, and moved three of the six nodes into that domain. A node that is a member of the fault domain fails. What is the expected result? An administrator has migrated a vCenter Server Appliance from version 5.5 to version 6.x. During the migration, the administrator selected DHCP for the appliance and obtained a hostname from the DHCP server. The administrator adjusts the hostname after the migration and uses a static IP and hostname. What should the administrator do immediately after this change to prevent service failures?
