1Y0-312 Advanced Provisioning and Image Management Practice Test 3 — 15 Questions

Question 1

An administrator is planning to implement Citrix Provisioning (PVS) to stream a vDisk to a new collection of target devices. The administrator needs to ensure that the target devices can boot from the network and access the vDisk. Which two actions must the administrator perform? (Choose two.)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Configure the target devices to boot from the network (PXE) in the BIOS/UEFI.. To boot from a PVS vDisk, target devices must be configured to boot from the network (PXE) and must have device records in the PVS console with the appropriate vDisk assigned. These two actions ensure that the devices can contact the PVS server, authenticate, and stream the vDisk. Other steps like installing target device software or enabling TFTP are either unnecessary or already handled by the PVS infrastructure.

Answer

Enable the TFTP service on the PVS server.

Answer

Configure the target devices to use a static IP address.

Answer

Install the Citrix Provisioning target device software on each target device.

Question 2

An administrator is managing a Citrix Provisioning (PVS) environment. The administrator needs to update a vDisk that is currently in Standard Image mode and in use by multiple target devices. The update must be applied without disrupting user sessions. Which two actions should the administrator take? (Choose two.)

Accepted Answer

Use a versioned vDisk and promote the new version after testing.. To update a vDisk in Standard Image mode without disrupting active sessions, the administrator can set the vDisk to Maintenance mode to apply updates, or use a versioned vDisk and promote the new version after testing. Both methods allow existing sessions to continue while the update is prepared, and devices will use the new version upon their next reboot.

Answer

Convert the vDisk to Private Image mode.

Answer

Restart all target devices to apply the update.

Answer

Update the vDisk directly while it is in Standard Image mode.

Question 3

An administrator is using Citrix Provisioning (PVS) and needs to update a vDisk that is currently in Standard Image mode. The administrator wants to make changes to the vDisk without affecting production users. What should the administrator do?

Accepted Answer

Set the vDisk to Maintenance mode, boot a target device, make changes, then revert to Standard Image mode.. To update a vDisk in Standard Image mode without affecting production users, the administrator should set the vDisk to Maintenance mode. This allows a target device to boot from the vDisk and make changes directly to it. After the updates, the vDisk can be reverted to Standard Image mode. Other methods like Private Image mode or MCS wizards are not appropriate for this scenario.

Answer

Set the vDisk to Private Image mode, boot a target device, make changes, then revert to Standard Image mode.

Answer

Use the 'Update Machines' wizard in Citrix Studio to apply changes to the vDisk.

Answer

Use the vDisk Versioning feature to create a new version, boot a target device, make changes, then promote the new version.

Question 4

An administrator is using Provisioning Services (PVS) to stream a vDisk to 200 target devices. The vDisk is in Private Image mode. The administrator needs to apply Windows updates to the vDisk without affecting the running production devices. Which procedure should the administrator follow?

Accepted Answer

Create a new vDisk version from the existing vDisk, set the new version to Maintenance mode, boot a maintenance device, install updates, then promote the version and set it to Standard Image mode.. The correct procedure involves converting the vDisk to Standard Image mode, creating a new version, setting it to Maintenance mode, applying updates via a maintenance device, then promoting the version and returning to Standard Image mode. This allows updates to be applied without impacting running devices, as they continue to use the current version until they reboot. This is a standard PVS image update workflow.

Answer

Shut down all target devices, change the vDisk to Standard Image mode, boot a maintenance device, install updates, then change back to Private Image mode and restart the devices.

Answer

Create a version of the vDisk, set it to Maintenance mode, boot a maintenance device, install updates, then promote the version and set it to Standard Image mode.

Answer

Set the vDisk to Standard Image mode, boot a maintenance device, install updates, then revert to Private Image mode.

Question 5

An administrator is using Citrix Provisioning (PVS) and has configured a vDisk in Standard Image mode with write cache set to 'Cache on device hard disk'. Users report that their changes are not persisting across reboots, and the target device's local disk is filling up. What is the most likely cause?

Accepted Answer

The write cache file is being cleared on reboot, so changes are lost, but the disk is filling up due to other files.. With 'Cache on device hard disk', the write cache file is stored on the target device's local disk. By default, this cache is cleared on reboot, so changes are not persistent. The local disk filling up could be due to the cache file not being deleted properly or other files. The combination of lost changes and disk filling is consistent with this configuration.

Answer

The write cache file is not being cleared on reboot, causing it to grow indefinitely.

Answer

The write cache is configured to be persistent, so changes are saved, but the disk is filling up.

Answer

The vDisk is in Private Image mode, so changes are written directly to the vDisk, causing the local disk to fill.

Question 6

An administrator is using Machine Creation Services (MCS) to create a catalog of 100 non-persistent machines. The master image is 60 GB. The administrator wants to minimize storage consumption on the shared storage repository. Which MCS storage option should the administrator select?

Accepted Answer

Use a shared base image with differencing disks.. The correct answer is to use a shared base image with differencing disks. MCS creates a single base image and a differencing disk for each machine, so the common data is stored only once. This minimizes storage consumption on the shared storage repository. Full clones duplicate the entire image, and thin provisioning does not deduplicate the base image. PVS is a different technology and not applicable here.

Answer

Thin provisioning with a 60 GB disk per machine.

Answer

Provisioning Services (PVS) with a standard image vDisk.

Answer

Full clones for each machine.

Question 7

An administrator is using Machine Creation Services (MCS) to provision a catalog of persistent machines. The administrator wants to ensure that each machine retains its unique applications and user data across reboots. Which MCS catalog type should the administrator create?

Accepted Answer

Dedicated with a persistent disk.. The correct answer is a dedicated catalog with a persistent disk. Dedicated machines are assigned to individual users and retain all changes to the system disk across reboots, including applications and user data. Pooled catalogs, even with Personal vDisk, do not persist system-level changes. The other options are either invalid or do not provide full persistence.

Answer

Pooled with Personal vDisk (PvD).

Answer

Pooled with a write-back cache.

Answer

Dedicated with a non-persistent disk.

Question 8

An administrator is managing a Provisioning Services environment and needs to update a target device image while ensuring zero downtime for users. Which method should the administrator employ to achieve this?

Accepted Answer

Create a new maintenance version of the vDisk, apply updates, and promote it to Production.. Versioned vDisks allow administrators to maintain a base image while creating child versions for updates. By promoting a version to 'Production', target devices receive the update upon reboot. This approach is critical for high availability, as it decouples the maintenance process from the live environment, allowing for controlled testing and rapid rollback if an update introduces instability or application compatibility issues within the production virtual desktop pool.

Answer

Perform a manual write-cache reset on each target device while users are active.

Answer

Directly modify the master VHDX file using an external disk management tool.

Answer

Set all target devices to 'Private Image' mode before applying updates.

Question 9

Refer to the exhibit. An administrator attempts to update a vDisk version but receives the provided error. What is the most likely cause?

Accepted Answer

A target device is currently booted in Private Image mode using the vDisk.. The 'vDisk locked' error occurs when the vDisk file is actively held by a process, such as a target device still running in 'Private Image' mode or a stuck VHDX handle on the Provisioning Server. This issue is critical because it prevents the promotion of new vDisk versions, halting deployment cycles. Resolving this requires identifying the locking process via the server console or Windows handle management tools to release the file lock.

Answer

The Provisioning Server service is stopped.

Answer

The vDisk is stored on a network share with incorrect NTFS permissions.

Answer

The vDisk manifest file is missing from the storage directory.

Question 10

An administrator is using Machine Creation Services (MCS) and wants to minimize the storage impact on the hypervisor. Which action should the administrator take?

Accepted Answer

Configure the write cache and identity disks to reside on local hypervisor storage.. MCS utilizes linked clones, which share a common base disk. By selecting 'Storage Optimization' or placing identity disks and write caches on local storage rather than shared storage, the administrator significantly reduces the I/O burden on the central SAN. This is critical for scaling large VDI deployments where storage latency often becomes the primary bottleneck for user performance and session responsiveness.

Answer

Use full clones for all machine catalogs to ensure maximum performance.

Answer

Increase the size of the master image to include all user applications.

Answer

Disable the base disk snapshot feature in the hypervisor.

Question 11

An administrator notices that after a PVS image update, several target devices are failing to boot, hanging at the 'Citrix Provisioning' splash screen. What is the most likely cause?

Accepted Answer

The target device cannot reach the Provisioning Server over the network.. Hanging at the splash screen typically indicates a network connectivity issue between the target device and the PVS server, or an incorrect boot file configuration. This is critical as it indicates that the target cannot successfully stream the vDisk data. Verification of DHCP options, PXE boot settings, and PVS server status is required to restore the target devices to an operational state.

Answer

The vDisk is set to Private mode.

Answer

The target device requires a newer version of the PVS target device software.

Answer

The vDisk is missing the latest Windows updates.

Question 12

Which component is responsible for streaming the virtual disk image to the target devices in a Provisioning Services environment?

Accepted Answer

Provisioning Server.. The Provisioning Server is the central component that streams the vDisk image to target devices over the network. This architecture allows multiple target devices to boot from a single, shared image, significantly simplifying patch management and deployment. Understanding this component is crucial for troubleshooting connectivity, performance, and ensuring that the streaming infrastructure can handle the concurrent load of all target machines in the site.

Answer

Citrix Studio.

Answer

Delivery Controller.

Answer

StoreFront.

Question 13

Which storage location is recommended for the write cache when using MCS to provide the best performance for virtual desktops?

Accepted Answer

Local hypervisor storage (e.g., SSD).. The write cache holds transient session data. Placing it on high-performance local storage (like SSDs) rather than shared storage (SAN) offloads I/O from the network and the primary storage array. This is a critical performance optimization, as VDI environments are often I/O intensive, and reducing latency for write operations significantly improves the user experience and the overall density of the host servers.

Answer

A low-speed, high-capacity SATA network share.

Answer

The same shared storage as the base disk.

Answer

A secondary, remote storage site.

Question 14

An administrator is troubleshooting a PVS environment and needs to verify if the correct vDisk version is being delivered. Which tool provides the most direct visibility into the boot vDisk version for a running target device?

Accepted Answer

The Provisioning Services Console.. The PVS console provides real-time information regarding which version of a vDisk a target device is currently using. This is essential for confirming that updates were successfully applied and that devices have migrated to the intended version. This visibility is vital for verifying deployment success and ensuring that troubleshooting is focused on the correct versioned image if issues arise after an update cycle.

Answer

Citrix Studio.

Answer

Event Viewer on the target device.

Answer

The hypervisor management console.

Question 15

What is the primary benefit of using a 'Standard' vDisk mode in Provisioning Services?

Accepted Answer

It facilitates image sharing among many target devices.. Standard mode allows multiple target devices to share a single vDisk in a read-only state, with changes written to a local write cache. This architecture is the backbone of efficient large-scale VDI. It minimizes storage requirements and simplifies management because updates only need to be applied once to the base image, rather than to every individual virtual desktop machine in the farm.

Answer

It enables full read/write access to the master vDisk for every device.

Answer

It provides a dedicated, persistent disk for every user.

Answer

It eliminates the need for a PVS server.
