Which action should the administrator take?

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

Accepted Answer

Boot a maintenance device from the Private Image vDisk, apply the patches, then shut down the maintenance device.. A Private Image vDisk is writable by only one target device at a time. To update it, an administrator boots a maintenance device from that vDisk, applies the necessary patches, and shuts down. This ensures that no other target devices are affected and that the changes are persisted directly to the vDisk. No mode changes or versioning are required for Private Image updates.

Answer

Set the vDisk to Standard Image mode, boot a maintenance device, apply patches, then shut down the maintenance device and set the vDisk back to Private Image mode.

Answer

Assign the vDisk to a target device, boot that device, apply patches, then shut down and set the vDisk to Standard Image mode.

Answer

Use the PVS console to version the vDisk, boot a target device from the new version, apply patches, then promote the version.

Question 2

An administrator is using Citrix Machine Creation Services (MCS) to provision a new machine catalog of non-persistent pooled VDI machines. The image has been updated with new applications and the administrator wants to roll out the update to all existing machines without disrupting user sessions. The environment uses a single hosting unit and a master image stored on a shared datastore. Which MCS feature should the administrator use to apply the update while minimizing storage consumption and downtime?

Accepted Answer

Use the 'Update Machines' wizard to update the existing machines with the new image, using a rolling update process to minimize impact.. In Citrix MCS, the Update Machines wizard is designed to apply a new master image to existing machines in a catalog. It can perform a rolling update, updating machines in batches to avoid service disruption. This is the standard procedure for image updates in MCS, and it maintains user assignments and settings while applying the new image.

Answer

Use the 'Update Machines' wizard to create new machines with the updated image and then delete the old ones, ensuring zero downtime.

Answer

Use the 'Update Machines' wizard to apply the new image to existing machines, leveraging Citrix Provisioning Services (PVS) streaming.

Answer

Update the master image and then use the 'Rollback' feature to revert machines to the previous image.

Question 3

An administrator supports a Citrix Virtual Apps and Desktops environment using Machine Creation Services (MCS) with a non-persistent machine catalog. After applying a new master image that includes an updated application, users report that their personal settings and application preferences are lost each time they log off. Which MCS feature should the administrator configure to preserve user-specific data across sessions while keeping the base image consistent?

Accepted Answer

Citrix User Profile Manager. Citrix User Profile Manager captures user-specific settings and preferences and stores them centrally so they can be applied consistently across non-persistent sessions. Unlike image-level solutions, it does not require altering the base image or changing the catalog type, and it works seamlessly with MCS. This makes it the correct choice for retaining personalization while maintaining a clean, standardized master image.

Answer

Citrix App Layering

Answer

MCS machine catalog with persistent desktops

Answer

Personal vDisk (PvD)

Question 4

An administrator is managing a Citrix Provisioning (PVS) environment with a vDisk in Private Image mode. A target device needs to apply Windows updates and install a new application. After making changes, the administrator wants to revert the vDisk to its original state and then make the changes available to all devices in the collection. Which sequence of actions should the administrator perform?

Accepted Answer

In Private Image mode, apply changes, then use the 'Merge' option to create a new Standard Image version.. To make changes from a Private Image vDisk available to all devices, the administrator must use the Merge function. This creates a new Standard Image version that incorporates the changes. The original vDisk can be reverted, and the new version can be assigned to the collection. This process ensures that changes are applied consistently and that the vDisk management remains within the PVS framework.

Answer

In Private Image mode, apply changes, then use the 'Promote' option to make the version available to all devices.

Answer

Set the vDisk to Standard Image mode, apply changes, then set to Private Image mode and promote the version.

Answer

In Private Image mode, apply changes, then manually copy the vDisk file to the Standard Image folder and update the database.

Question 5

An administrator is managing a Citrix Virtual Apps and Desktops environment with Provisioning Services (PVS). The administrator needs to update a vDisk that is currently in Private Image mode. The update must be applied to all target devices while minimizing downtime. Which two actions should the administrator perform? (Choose two.)

Accepted Answer

Set the vDisk to Standard Image mode and boot the maintenance device.. To update a vDisk in Private Image mode for multiple devices, you must change it to Standard Image mode and use a maintenance device to apply updates. Then, promote the new version to make it available to all target devices. This process allows for controlled updates with minimal downtime.

Answer

Configure the vDisk to use cache on server disk.

Answer

Run the 'Update vDisk' wizard from the PVS Console and select all target devices.

Answer

Assign the vDisk to a new device collection and set it to Private Image mode.

Question 6

An administrator manages a Citrix Provisioning (PVS) environment with multiple vDisk versions. The vDisk is in Private Image mode and has three versions. The administrator needs to revert a target device to a previous version of the vDisk without affecting other devices. The target device is currently booted from the latest version. What should the administrator do?

Accepted Answer

Assign the target device to a different vDisk that is a copy of the previous version.. In PVS, vDisk versions are managed at the vDisk level, and changing the current version affects all devices using that vDisk. To revert a single device, the administrator must isolate it by creating a copy of the previous version and assigning it to the device. This is especially relevant in Private Image mode where each device typically has its own vDisk, but if shared, copying ensures no impact on others.

Answer

Use the 'Versions' dialog for the vDisk to promote the previous version to 'Current' and then reboot the target device.

Answer

Change the vDisk to Standard Image mode and then assign the previous version to the target device.

Answer

In the target device's properties, select the previous vDisk version from the 'Boot from' drop-down list.

Question 7

An administrator manages a Citrix Provisioning (PVS) environment with multiple vDisk versions. The help desk reports that a recent vDisk update introduced a critical bug, and users need to revert to the previous working version immediately. The administrator has the previous version available in the vDisk store. Which action should the administrator take to ensure that all target devices in the collection boot from the previous vDisk version on their next restart?

Accepted Answer

In the PVS console, promote the previous vDisk version to the highest priority in the vDisk version list.. The vDisk version priority list in PVS determines the boot order for target devices. Promoting the previous working version to the highest priority ensures that devices boot from it on their next restart, effectively reverting the update. This method is non-destructive and allows the administrator to keep the buggy version for later analysis or patching.

Answer

In the PVS console, set the previous vDisk version to Maintenance mode and assign it to the collection.

Answer

In the PVS console, change the vDisk to Private Image mode and assign it to the collection.

Answer

In the PVS console, delete the buggy vDisk version and then restart the target devices.

Question 8

An administrator is managing a Citrix Provisioning (PVS) environment with multiple vDisk versions. A new version of a vDisk has been created and is currently in Maintenance mode. The administrator needs to test the new version on a single target device before rolling it out to the entire collection. Which action should the administrator take?

Accepted Answer

Set the new vDisk version's access mode to Maintenance, assign it to a test target device, and boot that device.. To test a new vDisk version on a single target device, the administrator should set the version's access mode to Maintenance and assign it to that device. Maintenance mode allows the version to be booted by a device without making it available to the entire collection. This enables safe testing before promoting the version to Production.

Answer

Promote the new vDisk version to Production, then boot a test target device from it.

Answer

Assign the new vDisk version to a test target device and set the device's boot mode to Maintenance.

Answer

Create a new vDisk from the new version, assign it to a test target device, and boot that device.

Question 9

An administrator is using Citrix Provisioning (PVS) to provision a pool of non-persistent target devices. The vDisk is in Private Image mode and must be updated with the latest operating system patches. The administrator needs to apply the patches without affecting any production target devices. Which action should the administrator take?

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

Accepted Answer

Standard Image with a shared write cache. Using Standard Image mode with a shared write cache enables multiple target devices to share a single vDisk image and a common write cache. When the base vDisk is updated, all devices immediately access the new version without rebooting, because they are streaming from the same image. This provides simultaneous updates across the collection.

Answer

Standard Image with Cache on Server

Answer

Standard Image

Answer

Private Image

Question 10

An administrator is using Machine Creation Services (MCS) to provision a machine catalog in a Citrix Virtual Apps and Desktops 7 environment. The administrator needs to reduce storage consumption for the catalog. Which two actions should the administrator take? (Choose two.)

Accepted Answer

Configure the catalog to use a shared master image with differencing disks.. To reduce storage consumption in MCS, the administrator can use thin-provisioned storage, which allocates space only as needed, and configure the catalog to use a shared master image with differencing disks (linked clones), which minimizes the storage per machine. These two actions directly reduce the storage footprint. Write-back cache, deduplication, and increasing write cache size do not achieve this goal.

Answer

Enable write-back cache on the master image.

Answer

Enable deduplication on the storage array.

Answer

Increase the write cache size on each machine.

Question 11

An administrator is using Citrix Provisioning (PVS) to stream a vDisk to 50 target devices. The vDisk is in Private Image mode. A user reports that changes made to the desktop are lost after a reboot. What is the most likely cause?

Accepted Answer

The vDisk is in Standard Image mode and the write cache is set to cache on server.. In Standard Image mode, multiple target devices share a single vDisk image, and all writes are redirected to a write cache. If the write cache is configured as 'Cache on server', the changes are stored on the PVS server but are not persistent across reboots by default. Therefore, user changes are lost after a reboot. Private Image mode would persist changes, so it is not the cause.

Answer

The vDisk is in Private Image mode, which does not persist changes.

Answer

The vDisk is in Standard Image mode and the write cache is set to cache on device RAM.

Answer

The vDisk is in Private Image mode and the write cache is disabled.

Question 12

An administrator is using Citrix Provisioning (PVS) to provision a pool of non-persistent target devices. The vDisk is in Private Image mode and must be updated with the latest operating system patches. The administrator needs to apply the patches without affecting any production target devices. Which action should the administrator take?

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

Accepted Answer

Enable write cache in RAM with overflow to disk.. The high disk latency on target devices' local disks indicates that the write cache is a bottleneck. Enabling write cache in RAM with overflow to disk uses the much faster RAM for most write operations, dramatically reducing disk I/O and latency. This improves logon and application performance without overloading the PVS server or network.

Answer

Move the vDisk to a faster storage repository on the PVS server.

Answer

Change the write cache type to Cache on server.

Answer

Increase the size of the local write cache disk.

Question 13

An administrator is using Machine Creation Services (MCS) to provision a catalog of 500 non-persistent Windows 10 desktops. The administrator notices that provisioning is taking a long time and is concerned about storage consumption. The environment uses a storage array that supports thin provisioning. Which action should the administrator take to optimize storage usage and provisioning time?

Accepted Answer

Enable 'Fast Clone' in the hosting connection settings.. Fast Clone leverages thin provisioning and array-based cloning to create virtual machines quickly and with minimal storage consumption. Enabling this feature in the hosting connection is the correct action to optimize both provisioning time and storage usage for MCS catalogs.

Answer

Configure the catalog to use a differencing disk for each machine.

Answer

Use a smaller master image by removing unnecessary applications.

Answer

Increase the number of provisioning servers in the site.

Question 14

An administrator is using Citrix Machine Creation Services (MCS) to provision a catalog of persistent machines for a group of developers. The developers need to retain their personal settings and installed applications across reboots. The administrator wants to minimize storage costs while meeting this requirement. Which MCS provisioning method should the administrator choose?

Accepted Answer

Dedicated with a differencing disk.. For persistent machines that retain user settings and applications, MCS offers dedicated machines with differencing disks. This method assigns a dedicated machine to each user, and the differencing disk captures changes, which persist. It is more storage-efficient than full clones because the base image is shared, reducing overall storage consumption.

Answer

Pooled with a differencing disk.

Answer

Pooled with a Personal vDisk (PvD).

Answer

Dedicated with a full clone.

Question 15

An administrator is preparing a master image for a Citrix Virtual Apps and Desktops environment using Machine Creation Services (MCS). The administrator wants to ensure that the master image is properly prepared to avoid issues with machine creation. Which action should the administrator take before sealing the image?

Accepted Answer

Install the Citrix Virtual Delivery Agent (VDA) and then run the appropriate sealing command, such as sysprep or the Citrix image preparation tool.. Before using a master image with MCS, you must install the Citrix Virtual Delivery Agent and then seal the image using the appropriate method, such as sysprep or the Citrix image preparation tool. This generalizes the image and removes unique identifiers, allowing MCS to create multiple identical machines without conflicts.

Answer

Install the Citrix Virtual Delivery Agent (VDA) and then run the Citrix Machine Creation Services preparation script.

Answer

Install the Citrix Virtual Delivery Agent (VDA) and then run the MCS image preparation tool.

Answer

Run the MCS preparation script.
