- An administrator is responsible for enabling file access for desktop users. Many users have complained that they cannot access their files. An alert in the vSphere Client states that the storage connectivity alarm for all hosts has been triggered. The storage screen indicates that everything is connected, but the triggered alert has not been acknowledged. Which action will correct the user access problem?
- An administrator is updating a program running on a virtual machine. The update file has been downloaded as an .iso file and placed on a shared NFS datastore. An attempt to mount the .iso file to the virtual machine fails, but subsequent testing shows that the .iso file can be mounted to a virtual machine running on another ESXi host. Which step can be taken to enable access to the .iso file for the affected virtual machine?
- An administrator is unable to connect a vSphere Client to an ESXi host. Which option can be selected from the direct console to restore connectivity without disrupting running virtual machines?
- An administrator is setting up vMotion in a vSphere environment. A migration is run to test the configuration, but fails. What could the administrator do to resolve the issue?
- A vSphere 5 implementation consists of a fully automated DRS cluster with two ESXi 5.x hosts with the following vSphere Standard Switch configuration: 1. Switch A. three vmnics, one port group named sFTP-PG 2. Switch B. two vmnics, one port group named Web-PG 3. All vmnics are trunked to the same physical switch.
- During a physical network reconfiguration, an ESXi host briefly lost connection to the management network. High Availability (HA) began powering off the virtual machines residing on the affected host to be restarted on an unaffected host in the cluster. Which setting should the administrator configure to prevent this type of HA failover during planned maintenance?
- An administrator needs to create an alarm to monitor when a specific ESXi host in an HA/DRS cluster becomes disconnected from other vSphere components like HA agents or the vCenter Server. Which process must the administrator use to accomplish this?
- An administrator needs to install vSphere Update Manager using an external SQL Server 2008 R2 database. The administrator has created the database successfully, but cannot establish connectivity when testing the DSN. Which configuration setting could be causing the issue?
- A vSphere administrator needs the ability to adjust the amount of guaranteed physical CPU and memory resources to a virtual machine without incurring application downtime. Which actions must the administrator perform?
- A vSphere administrator needs to add a CPU to a virtual machine, but upon editing the VM settings the option is grayed out. What would explain this behavior?
- A vSphere administrator is attempting to upgrade an ESXi host using vSphere Update Manager. The administrator has attached the baseline and remediated the host. Update Manager reports the remediation process has completed successfully. However, upon inspection the host is not upgraded. What is the most likely reason for this issue?
- An application administrator reports application slowness when loading the application's web portal. The virtual machine is currently connected to a vSphere Distributed Switch. The application owner requests information about the virtual machine's network traffic. Which feature of a vSphere Distributed Switch should the administrator use to gather the needed information?
- An administrator is evaluating whether to deploy vCenter Server on a Windows server or as a vCenter Server appliance. The administrator has the following requirements: Utilize a web browser to manage the vSphere environment. 16 ESXi hosts will be managed. Licenses must be shared with the vCenter Server environment at another site. An external Oracle 10g database server will be used for the vCenter Server database. Why will the administrator need to deploy vCenter Server on a Windows server?
- An organization is designing a new vSphere cluster to support a new product implementation. The following challenges have been identified by the vSphere administration team:
- Which feature requires an administrator using an RDM to configure it with virtual compatibility mode?
- A vSphere administrator is unable to power on a virtual machine that resides in a HA cluster. The administrator determines that the virtual machine has a larger reservation than existing virtual machines. Which cluster setting should the administrator modify to enable the virtual machine to power on?
- An administrator needs to configure vFlash Read Cache to improve performance. What would benefit the most from enabling vFlash Read Cache?
- A vSphere administrator is attempting to migrate a virtual machine, but the progress bar for the migration remains at 10%. Which issue could be preventing the vMotion migration?
- A vSphere administrator configures a preferred heartbeat datastore in an HA/DRS cluster configuration. The vCenter Server identifies an alternative preferred datastore. Why would vCenter Server identify an alternative preferred datastore over the administrator's preference?
- An ESXi 5.x host disconnects within 60 seconds after the administrator adds it to the vCenter Server inventory. The administrator determines that the issue could be related to a networking problem. Which networking port should the administrator check for connectivity from the host to vCenter Server?
- 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?
- An administrator is using vSphere Replication to replicate a number of virtual machines to a recovery site. The administrator plans on enabling Storage DRS on the production site, which is running vSphere 5.5. What changes must be made in order to support this configuration?
- A customer needs to create a virtual machine that can be migrated across multiple vSphere clusters. The virtual machine has an application that must detect the physical characteristics of the storage device. Which type of virtual disk can be added to the virtual machine to meet these requirements?
- What is the minimum virtual machine compatibility setting required for a virtual machine to run on a vSphere 5.5 host?
