1Y0-312 Practice Test 4 — 25 Questions

Question 1

A Citrix architect is designing a new Citrix Virtual Apps and Desktops 7 site. The company wants to minimize the number of machines required in the data center while ensuring that the site database is highly available. The architect decides to use SQL Server Always On availability groups. What is the minimum number of SQL Server instances required to support this configuration?

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

Accepted Answer

Two SQL Server instances configured in an Always On availability group.. SQL Server Always On availability groups require at least two SQL Server instances to provide high availability. One instance acts as the primary replica, and the other as the secondary replica. This configuration allows automatic failover if the primary fails, ensuring the Citrix site database remains available with minimal additional infrastructure.

Answer

Three SQL Server instances configured in an Always On availability group.

Answer

Four SQL Server instances configured in an Always On availability group.

Answer

One SQL Server instance with Always On availability groups configured on a single node.

Question 2

An administrator manages a Provisioning Services environment with a vDisk in Private Image mode used by a single target device for image maintenance. After completing updates, the administrator needs to make those updates available to the rest of the collection while still allowing the original maintenance device to receive further changes. Which action should the administrator take?

Accepted Answer

Promote the updated vDisk to the production version and assign the maintenance device to a new private maintenance version.. In Provisioning Services, a maintenance device boots a private image to make changes, and once the updates are validated the administrator promotes that version so the rest of the collection boots the updated production image. Giving the maintenance device a separate private maintenance version keeps it writable for ongoing work while production devices consume the promoted read-only version.

Answer

Delete the existing vDisk version and create a new vDisk from the maintenance device's disk.

Answer

Change the vDisk to Standard Image mode and set the maintenance device to boot from a private version of that vDisk.

Answer

Set the vDisk to Cache on server mode and enable versioning so all devices share the maintenance device's changes.

Question 3

An administrator is troubleshooting a Citrix Virtual Apps and Desktops 7 environment where a published application launches but the user sees a black screen for 30 seconds before the application appears. The VDA is healthy, and no errors are logged. The administrator suspects that a logon script is delaying the session. Which tool should the administrator use to analyze the session startup phases and identify the delay?

Accepted Answer

Citrix Director's 'Session Details' with the 'Logon Duration' breakdown. Citrix Director's Logon Duration breakdown is the correct tool because it decomposes the logon into phases, including interactive session, GPO, profile, and script execution. By examining this breakdown, the administrator can see which phase consumes the 30 seconds and confirm whether a logon script is responsible. Other tools lack this Citrix-specific phase analysis.

Answer

Citrix Studio's 'Monitoring' tab with the 'Connection Failures' report

Answer

Windows Performance Monitor on the VDA with the 'Logon' counter set

Answer

Citrix Workspace app 'Connection Center' diagnostics

Question 4

A Citrix Virtual Apps and Desktops 7 administrator is troubleshooting an issue where a published application fails to launch for a specific user. The administrator wants to view the detailed launch error in the Citrix Workspace app. Where should the administrator look for the log file?

Accepted Answer

%LOCALAPPDATA%\Citrix\Workspace\Logs. The Citrix Workspace app log files are located in %LOCALAPPDATA%\Citrix\Workspace\Logs. These logs record detailed client-side events, including application launch errors. The other locations are either for different components or do not contain user-specific Workspace app logs. Checking the correct path allows the administrator to quickly identify the cause of the launch failure.

Answer

%PROGRAMDATA%\Citrix\Workspace\Logs

Answer

Event Viewer under Applications and Services Logs > Citrix > Workspace

Answer

%SystemRoot%\System32\LogFiles\Citrix\Workspace

Question 5

An administrator is reviewing a Citrix Virtual Apps and Desktops 7 site where users connect through Citrix Gateway. Users report that their sessions disconnect when they move between wireless access points in the office. The administrator wants to keep sessions alive during these brief network interruptions without requiring users to reauthenticate. Which Citrix Gateway setting should the administrator configure?

Accepted Answer

Session Reliability. Session Reliability preserves the ICA session on the VDA when the client connection is temporarily lost, so brief wireless roaming interruptions do not force users to reconnect or reauthenticate. The session appears frozen until connectivity returns, then resumes, which matches the requirement to keep sessions alive during access point transitions.

Answer

HDX Insight

Answer

Clientless Access

Answer

SmartAccess

Question 6

An administrator is configuring Citrix StoreFront to use HTTPS for all communications. The security team requires that the StoreFront server uses a certificate that is trusted by all user devices. The administrator has obtained a certificate from a public CA and installed it on the StoreFront server. Which StoreFront configuration must be updated to bind the certificate to the IIS website?

Accepted Answer

In IIS Manager, edit the bindings for the StoreFront website and add an HTTPS binding with the certificate.. Binding an SSL certificate to the StoreFront website is done in IIS Manager by editing the site bindings and adding an HTTPS binding with the desired certificate. This ensures that the website presents the correct certificate to clients. Other options either set URLs or manage services but do not perform the actual binding. Without the IIS binding, HTTPS will not function correctly, and users may see certificate errors.

Answer

Configure the StoreFront server to use the certificate in the Citrix Delivery Services console.

Answer

Run the PowerShell cmdlet Set-STFWebReceiverService with the -HttpsPort parameter.

Answer

Use the StoreFront management console to change the base URL to HTTPS.

Question 7

An administrator is using Machine Creation Services (MCS) to provision a catalog of non-persistent machines in Citrix Virtual Apps and Desktops. The administrator needs to update the master image with a new application and roll it out to all machines in the catalog. Which action should the administrator take?

Accepted Answer

Update the master image, then use the Citrix Studio console to update the catalog to use the new image.. For MCS-provisioned catalogs, the standard method to roll out a new master image is to update the master image and then use Citrix Studio to update the catalog. This process creates new identity disks for each machine based on the updated image, while optionally preserving user personalization. It is automated and does not require manual recreation of machines.

Answer

Update the master image, then manually delete and recreate each machine in the catalog to pick up the new image.

Answer

Update the master image, then use Provisioning Services to update the vDisk and reboot the target devices.

Answer

Update the master image, then use the PowerShell cmdlet Update-ProvScheme to apply the new image to the catalog.

Question 8

An administrator is using Machine Creation Services (MCS) to provision a new catalog of 200 non-persistent Windows 10 desktops from a master image. The master image was created on a host with a different CPU generation than the target hosts. Users report that after provisioning, the desktops fail to boot with a STOP error 0x0000005A. Which action should the administrator take to resolve this issue?

Accepted Answer

Recreate the master image on a host with the same CPU generation as the target hosts.. The 0x0000005A STOP error indicates an unsupported processor. When using MCS, the master image must be created on a host with the same CPU generation as the target hosts to ensure compatibility. Recreating the master image on a compatible host resolves the issue, while other options do not address the CPU mismatch.

Answer

Modify the catalog to use a different storage repository with higher IOPS.

Answer

Run the 'Update Machines' wizard to push a new image to the existing desktops.

Answer

Enable the 'Use machine creation services (MCS) with a hardware-accelerated graphics' option in the catalog.

Question 9

An administrator is migrating an on-premises Citrix Virtual Apps and Desktops 7 site to Citrix DaaS. The on-premises site uses a Citrix Gateway (formerly NetScaler) for external access. After migration, the administrator wants to continue using the existing Citrix Gateway to provide external access to the published resources. Which statement correctly describes the integration of an on-premises Citrix Gateway with Citrix DaaS?

Accepted Answer

The on-premises Citrix Gateway can be used with Citrix DaaS by configuring it to point to the Citrix Workspace URL or a StoreFront server that is integrated with Citrix DaaS, and it does not require a Cloud Connector on the Gateway itself.. An on-premises Citrix Gateway can be leveraged with Citrix DaaS by configuring it to direct users to the Citrix Workspace URL or an integrated StoreFront server. This allows organizations to maintain their existing external access infrastructure without deploying a Cloud Connector on the Gateway. Cloud Connectors are still required to connect the on-premises resource location to Citrix Cloud for VDA registration and communication.

Answer

The on-premises Citrix Gateway can be integrated with Citrix DaaS by using the Citrix Gateway service in Citrix Cloud, which requires the Gateway to be registered with Citrix Cloud.

Answer

The on-premises Citrix Gateway can be used with Citrix DaaS by configuring it as a StoreFront server, and it requires a Cloud Connector to be installed on the Gateway.

Answer

The on-premises Citrix Gateway can be used with Citrix DaaS only if it is first migrated to Citrix Cloud and configured as a Gateway Connector within the Citrix Cloud console.

Question 10

A Citrix architect is designing a new Citrix Virtual Apps and Desktops 7 site. The company wants to minimize the number of machines required in the data center while ensuring that the site database is highly available. The architect decides to use SQL Server Always On availability groups. What is the minimum number of SQL Server instances required to support this configuration?

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

Accepted Answer

SQL Server Always On availability groups. Always On availability groups are the recommended SQL Server high-availability feature for Citrix Virtual Apps and Desktops 7. They provide a listener that acts as a single connection point, enabling the Delivery Controllers to automatically reconnect to the new primary replica after a failover. This eliminates manual reconfiguration and ensures database high availability.

Answer

SQL Server transactional log shipping

Answer

SQL Server replication

Answer

SQL Server failover cluster instances

Question 11

A Citrix Administrator is configuring a Citrix Gateway to use Smart Card authentication for external users. The environment uses a two-factor authentication requirement: smart card and Active Directory password. The administrator has configured the Gateway virtual server with a Smart Card authentication policy and an LDAP authentication policy. Users report that they are only prompted for the smart card and not for the LDAP password. What should the administrator do to enforce the two-factor authentication?

Accepted Answer

Configure the Smart Card authentication policy to use 'Next Factor' and specify the LDAP policy as the next factor.. To enforce two-factor authentication with smart card and LDAP, the administrator must configure the Smart Card authentication policy to include a 'Next Factor' that points to the LDAP policy. This creates a chain where the user first authenticates with the smart card and then is prompted for LDAP credentials. Simply binding both policies does not chain them; the next-factor configuration is essential.

Answer

Set the LDAP authentication policy to 'Secondary' and bind it to the Gateway virtual server after the Smart Card policy.

Answer

Enable 'Two-factor Authentication' in the Gateway virtual server settings and select both Smart Card and LDAP from the drop-down list.

Answer

Bind both the Smart Card and LDAP policies to the Gateway virtual server and set the priority so that LDAP is evaluated first.

Question 12

An administrator is configuring a Citrix ADC to load balance traffic to a StoreFront server group. Users occasionally experience failed connections when a StoreFront server becomes unavailable, and the administrator wants the ADC to stop sending new requests to that server while allowing existing sessions to complete. Which ADC feature should the administrator configure?

Accepted Answer

Configure a health monitor with a short interval and enable graceful shutdown on the service.. A health monitor quickly identifies the failed StoreFront server, and graceful shutdown on the service allows the ADC to drain existing connections while refusing new ones. This combination prevents new requests from reaching the unhealthy server and preserves ongoing sessions, which is exactly what the administrator needs.

Answer

Enable session persistence based on source IP.

Answer

Configure a backup virtual server with a lower priority.

Answer

Enable HTTP compression on the load balancing virtual server.

Question 13

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 should not disrupt the running devices, and the administrator wants to be able to roll back if issues arise. Which action should the administrator take?

Accepted Answer

Create a new version of the vDisk, apply updates to the new version, and then promote it.. Creating a new version of the vDisk is the correct approach for updating a Standard Image vDisk without disrupting running devices. The new version can be updated offline, then promoted to become the boot version. The previous version remains available for rollback. Other methods either disrupt service or are not applicable to Standard Image mode.

Answer

Set the vDisk to Private Image mode, apply updates, then revert to Standard Image mode.

Answer

Use the 'Merge' function to combine changes from a differencing disk into the base vDisk.

Answer

Update the master image directly on the provisioning server and restart the Stream Service.

Question 14

An administrator is designing a Citrix Provisioning (PVS) environment for a large deployment of 500 target devices. The administrator needs to ensure high availability and optimal performance for the vDisk store. The environment uses a shared storage solution. Which two actions should the administrator take to meet these requirements? (Choose two.)

Accepted Answer

Configure multiple PVS servers in a farm and load balance them.. To achieve high availability and performance in a large PVS deployment, administrators should deploy multiple PVS servers in a farm with load balancing, and use shared storage for the vDisk store. This combination ensures that if a server fails, others can take over, and shared storage provides a single source of truth for vDisks, avoiding replication issues.

Answer

Enable write cache on the PVS servers to reduce disk I/O.

Answer

Place the vDisk store on a local disk on each PVS server.

Answer

Configure the vDisk store to use a RAID 0 array for maximum performance.

Question 15

An administrator is deploying Citrix Profile Management for a pooled VDI catalog on shared storage. Users report that logons take over 60 seconds and the storage array shows heavy random read activity during morning logon storms. Which configuration in the Profile Management policy should the administrator enable to reduce this I/O load?

Accepted Answer

Enable Profile streaming.. Profile streaming is designed to reduce logon I/O by not copying the entire profile at logon. It retrieves files on demand, which lowers random read pressure on shared storage and speeds logons during a boot or logon storm. Active write back, Cloud Connector caching, and AppData redirection do not defer profile reads and therefore do not solve the described bottleneck.

Answer

Enable Citrix Cloud Connector caching.

Answer

Enable Folder Redirection for AppData.

Answer

Enable Active write back.

Question 16

An administrator is configuring a Citrix Provisioning (PVS) environment. The administrator needs to ensure that target devices can boot from the network and receive the vDisk. Which two components must be configured? (Choose two.)

Accepted Answer

TFTP server. For PVS target devices to boot from the network, a TFTP server must be available to provide the bootstrap file, and a DHCP server must be configured with options 66 and 67 to direct the device to the TFTP server and boot file. These two components are essential for the initial boot process. Other components like DNS or Certificate Authority are not required for basic network boot.

Answer

Streaming service with a provisioned vDisk

Answer

DNS server with SRV records

Answer

Certificate Authority server

Question 17

An administrator is migrating an on-premises Citrix Virtual Apps and Desktops 7 site to Citrix DaaS. The on-premises site uses machine catalogs with MCS provisioned machines on vSphere. The administrator plans to use Citrix Cloud Migration Service to migrate the site. Which two components must be present in the on-premises environment to support the migration? (Choose two.)

Accepted Answer

The on-premises Delivery Controllers must be running a supported version and have the Migration Service agent installed.. The two required components are Citrix Cloud Connectors and the Migration Service agent on supported Delivery Controllers. Cloud Connectors enable secure communication between the on-premises resource location and Citrix Cloud, while the Migration Service agent on Delivery Controllers facilitates the actual migration of site configuration. These are essential for the Migration Service to inventory and transfer the site to Citrix DaaS. Other components like Citrix Gateway or StoreFront are not prerequisites for the migration process itself.

Answer

The on-premises site must be configured with a Citrix ADC for load balancing.

Answer

A Citrix Gateway configured for remote access.

Answer

A Citrix StoreFront server with the latest cumulative update.

Question 18

An administrator supports a Citrix Virtual Apps and Desktops 7 environment where the Delivery Controller database is hosted on a dedicated Microsoft SQL Server instance. During the morning logon peak, the Controller takes over 45 seconds to respond to brokering requests, and the SQL Server shows sustained 90% CPU with heavy read activity against the monitoring data tables. The administrator must reduce the database load without redesigning the site. Which action should the administrator take?

Accepted Answer

Move the monitoring database to a separate SQL Server instance and point the Monitoring Database connection string to that instance.. Monitoring data generates the majority of SQL activity in a busy Citrix site because every session, logon, and application event is recorded. Placing the monitoring database on its own SQL Server instance separates that write-heavy workload from the configuration database that brokers sessions, so brokering queries stop competing for the same CPU and I/O. This is a supported, minimally disruptive change that directly addresses the observed symptom.

Answer

Enable the Citrix Director data collection caching option on each VDA to reduce the number of monitoring records sent to SQL.

Answer

Configure the Delivery Controller to use SQL Server Express LocalDB for the monitoring database.

Answer

Increase the SQL Server maximum degree of parallelism to 8 so that brokering queries are processed in parallel.

Question 19

An administrator is migrating an on-premises Citrix Virtual Apps and Desktops site to Citrix DaaS. The on-premises site uses a Citrix ADC for load balancing of StoreFront servers. The administrator wants to replace the on-premises StoreFront with Citrix Workspace and ensure high availability. Which two actions should the administrator take to ensure that users can access resources after migration? (Choose two.)

Accepted Answer

Install Cloud Connectors in the resource location.. To ensure user access after migrating to Citrix DaaS with Citrix Workspace, the administrator must install Cloud Connectors in the resource location to enable communication between Citrix Cloud and on-premises resources. Additionally, configuring Citrix Workspace to use Citrix Gateway service provides secure external access. These two actions replace the on-premises StoreFront and Citrix ADC, ensuring high availability and continuous access for users.

Answer

Migrate the StoreFront server to an Azure virtual machine.

Answer

Deploy a new Citrix ADC in Citrix Cloud.

Answer

Configure Citrix Workspace to use the on-premises Citrix ADC for load balancing.

Question 20

A Citrix Virtual Apps and Desktops 7 administrator is troubleshooting a Delivery Controller that intermittently fails to broker sessions, with users receiving 'No machines available' errors even though the Delivery Group shows available machines. The administrator notices the issue occurs during peak hours and resolves after a few minutes. Which action should the administrator take to identify the cause?

Accepted Answer

Review the Citrix Broker Service logs and the site database performance counters during peak hours.. Intermittent brokering failures that correlate with peak hours and resolve quickly suggest a performance or contention issue in the brokering path, often involving the site database or the Broker Service itself. Reviewing Broker Service logs alongside database performance counters during peak load provides the evidence needed to pinpoint slow queries, timeouts, or throttling, which is the correct diagnostic action.

Answer

Increase the number of Delivery Controllers in the site and enable load balancing.

Answer

Check the VDA's registration status and restart the Citrix Desktop Service on all machines.

Answer

Recreate the Delivery Group and re-add the machines to refresh the broker's machine cache.
