1Y0-312 Practice Test 10 — 10 Questions

Question 1

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.)

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

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 2

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 3

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 4

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 5

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.

Question 6

An administrator is configuring Citrix Gateway to use Adaptive Authentication. The security team wants to require multi-factor authentication (MFA) only when users connect from outside the corporate network. Which Citrix ADC policy expression should the administrator use to trigger MFA based on the user's location?

Accepted Answer

CLIENT.IP.SRC.IN_SUBNET(10.0.0.0/8).NOT. To trigger MFA only for external users, the policy must evaluate to true when the client IP is outside the corporate subnet. The expression CLIENT.IP.SRC.IN_SUBNET(10.0.0.0/8).NOT does exactly that by negating the subnet check. This allows the administrator to bind an MFA policy that applies only to external connections.

Answer

CLIENT.IP.SRC.IN_SUBNET(10.0.0.0/8)

Answer

HTTP.REQ.HEADER("User-Agent").CONTAINS("Citrix")

Answer

http.REQ.IS_VALID

Question 7

An administrator is configuring a new Citrix Virtual Apps and Desktops environment for a call center with 500 users. The users access a set of published applications that are resource-intensive. The administrator wants to ensure that the environment can scale to handle peak loads without over-provisioning hardware. Which Citrix feature should the administrator use to dynamically adjust the number of powered-on machines based on user demand?

Accepted Answer

Citrix Autoscale in Delivery Group power management. Citrix Autoscale is designed to automatically manage the power state of machines in a Delivery Group based on schedules and load. It ensures that enough machines are available during peak times and powers off unused machines during off-peak, optimizing resource usage and cost. The other options are provisioning or optimization tools that do not provide dynamic scaling.

Answer

Citrix Provisioning (PVS) with standard vDisk mode

Answer

Citrix Workspace Environment Management (WEM) with CPU optimization

Answer

Citrix Machine Creation Services (MCS) with random allocation

Question 8

A Citrix architect is designing a Citrix Virtual Apps and Desktops 7 site that will span two datacenters connected by a 15 ms round-trip link. The Site database will be hosted in SQL Server Always On availability groups. The architect must ensure that the Database Connection string in the Site configuration points to a listener that remains valid after a database failover. Which SQL Server feature should the architect specify in the connection string?

Accepted Answer

The Always On availability group listener name with the MultiSubnetFailover=True keyword. An Always On availability group listener presents a stable name and IP that follow the active replica, so the Citrix Site connection string does not change after failover. Adding MultiSubnetFailover=True lets the client attempt all listener IP addresses simultaneously, which shortens reconnection across the 15 ms inter-datacenter link. This is the supported, resilient configuration for a multi-subnet SQL Server backend.

Answer

The primary replica's physical host name and instance name

Answer

A Windows Server Failover Clustering distributed network name (DNN) for the availability group

Answer

A DNS alias that maps to the current primary replica, updated by a scheduled PowerShell script

Question 9

A Citrix Administrator is configuring a Citrix Gateway to provide access to published applications. The administrator wants to ensure that users can only access resources if their device has a specific registry key set. Which Citrix Gateway feature should the administrator use?

Accepted Answer

Endpoint Analysis (EPA). Endpoint Analysis (EPA) is the Citrix Gateway feature that allows administrators to define scans to check for specific endpoint conditions, including registry keys. The results are used in authorization policies to control access. SmartAccess is the broader concept, the plug-in is the agent, and authentication policies verify user identity. Thus, EPA is the correct feature to enforce the registry key requirement.

Answer

SmartAccess

Answer

Authentication policy

Answer

Citrix Gateway plug-in

Question 10

An administrator needs to configure a Citrix Gateway to use Smart Card authentication for users connecting from outside the network. The environment uses Citrix Virtual Apps and Desktops 7 with StoreFront. The administrator has installed the Smart Card certificate on the Gateway and configured the LDAP authentication policy. What additional step must be taken on the Gateway to enable Smart Card authentication?

Accepted Answer

Enable Client Certificate authentication on the Gateway virtual server.. Enabling Smart Card authentication on Citrix Gateway requires enabling Client Certificate authentication on the Gateway virtual server. This setting prompts the client to present a certificate, which the Gateway validates against trusted CAs. The LDAP policy is used for authorization after certificate validation. Configuring a CRL is a security best practice but not the enabling step. RADIUS and Smart Card drivers are unrelated to the Gateway configuration.

Answer

Set the Gateway authentication policy to use RADIUS.

Answer

Configure a Certificate Revocation List (CRL) on the Gateway.

Answer

Install the Smart Card driver on the Gateway.
