VMware VCI550 Actual Free Exam Questions & Community Discussion

A vSphere administrator needs to add more space to an existing 3-node Virtual SAN cluster. The attempts to add the new host to the cluster as a contributing member have failed. However, it can be added as a non-contributing member.
The host was previously used in a single host configuration. The administrator recently upgraded the host from ESXi 5.1 to 5.5 prior to adding it to the cluster.
What is the reason for this failure?

An administrator receives the following error message: Unmanaged I/O workload detected on shared datastore. Which vSphere feature is the likely source of this error?

A vSphere administrator creates a new vSphere Distributed Switch. The administrator receives notice from the service desk that a cluster of vSphere hosts has disconnected from vCenter Server. This disconnect occurred immediately after the new switch was created.
This vSphere Distributed Switch is the only distributed switch managed by vCenter.
The virtual machines are still functional and the applications are still accessible by end users.
On the ESXi hosts, which step must the vSphere administrator take to allow vCenter Server to reconnect?

Which two steps can an administrator take to upgrade an existing VMFS2 datastore to VMFS5? (Choose two.)

What two IT infrastructure components are virtualized by vSphere Essentials? (Choose two.)

An administrator creates an ESXi cluster using vSphere Auto Deploy. The ESXi hosts are configured to get a management IP address from a DHCP server. The administrator needs to troubleshoot the management network on one of the hosts. Which DCUI option should the administrator use to renew the DHCP lease?

An administrator needs to export system logs for an ESXi 5.5 host to determine the root cause for a host performance issue. This host supports manifest-driven exports of system logs.
Which manifest is selected by default during the export system log wizard?

A vSphere administrator notices that hosts are not powering off when the total cluster load is low on a cluster configured with Dynamic Power Management.
What condition could cause this behavior?

An administrator needs to deploy several virtual machines. Storage contention between the virtual machines should be managed by the VMkernel. Some of the virtual machines will use MSCS and should be highly available across the ESXi 5.5 hosts.
Which two storage options meet these requirements? (Choose two.)

The load on a Fully Automated HA/DRS cluster is critically unbalanced. What condition could cause this issue?

During the installation of ESXi 5.5, the following error message is reported: Hardware Virtualization is not a feature of the CPU, or is not enabled in the BIOS. Which condition would generate this message?

An administrator needs to migrate a virtual machine from one datastore to another, but the virtual machine has a snapshot. The virtual machine is running on an ESXi 5.x host.
Which action must the vSphere administrator take to ensure that the snapshot data remains intact?

A vSphere administrator has created a vSphere Standard Switch with one virtual machine port group and one physical uplink. The administrator needs to ensure that the virtual machines on this port group can communicate only with each other.
What should the administrator do?

A vSphere administrator needs to place an ESXi host in maintenance mode to replace a hardware component. This host is a member of a Virtual SAN cluster that uses Automatic Mode Disk Groups. Availability of virtual machines running on this host is critical. HA and DRS are enabled on the Virtual SAN Cluster. Otherwise, the Virtual SAN cluster uses default values.
Which action should the administrator take to automatically guarantee availability of virtual machines with the fastest migration time?

A vSphere administrator needs to configure a virtual machine to meet a guaranteed CPU performance profile.
Which configuration setting could the administrator choose?
