1Y0-204 Architecture Practice Test 2 — 15 Questions

Question 1

A Citrix architect is designing a Virtual Apps and Desktops environment that must support users in two regions. The architect plans to use a single Citrix Site with two zones. The company requires that users in each region connect to resources in their own region whenever possible, and that the solution remain functional if one region's Delivery Controllers fail. Which two design elements must the architect include to meet these requirements? (Choose two.)

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

Accepted Answer

Place Delivery Controllers in both zones and configure zone preference so each region's users prefer their local zone. Controllers in both zones with zone preference provide local brokering and failover, while a StoreFront server group across both regions ensures authentication and enumeration survive a regional outage. Together these elements satisfy both the locality and resilience requirements within a single Site.

Answer

Use a single Delivery Controller in the primary zone and rely on Local Host Cache in the secondary zone

Answer

Deploy a separate Citrix Site for each region and link the sites with a trust relationship

Answer

Configure all users with a single zone preference pointing to the primary zone regardless of their location

Question 2

An architect is designing a Citrix Virtual Apps and Desktops site that must survive the loss of an entire resource location. The design uses zones with a primary zone and a satellite zone, and each zone has its own SQL Server. Which statement correctly describes how zone data is maintained during normal operation?

Accepted Answer

The primary zone's Delivery Controllers write to the primary zone's SQL Server, and satellite zone Delivery Controllers write to the primary zone's SQL Server for all configuration changes.. In a multi-zone Citrix Virtual Apps and Desktops site, all Delivery Controllers write configuration changes to the SQL Server in the primary zone, which acts as the single source of truth. Satellite zone SQL Servers support Local Host Cache and zone resilience rather than receiving configuration writes, so the design survives the loss of a resource location without splitting the configuration store.

Answer

Each zone maintains an independent site database, and administrators must manually merge changes between zones.

Answer

Configuration is written to a shared file share that all zones read, and SQL Server is used only for session data.

Answer

Each zone's Delivery Controllers write only to the SQL Server in their own zone, and changes are replicated between the zone databases.

Question 3

A small company is deploying Citrix Virtual Apps and Desktops for 200 users in a single data center. The architect wants to minimize the number of infrastructure servers while still separating the web tier from the brokering tier. Which deployment model should the architect recommend?

Accepted Answer

Deploy two StoreFront servers and two Delivery Controllers as separate server roles.. Separating StoreFront and Delivery Controller roles onto dedicated servers provides a distinct web tier and brokering tier while maintaining redundancy. For a 200-user single-site deployment, two servers per role is a balanced design that avoids single points of failure and allows each tier to be managed independently without over-provisioning infrastructure.

Answer

Install StoreFront and Delivery Controller roles on the same two servers.

Answer

Deploy StoreFront on the same servers as Citrix Gateway and keep Delivery Controllers internal.

Answer

Deploy a single StoreFront server and a single Delivery Controller.

Question 4

A retail company is designing a Citrix Virtual Apps and Desktops environment for 2,000 users across 50 stores. The stores have limited bandwidth and intermittent connectivity to the datacenter. The architect wants to reduce the impact of WAN outages on user sessions and ensure that users can still launch sessions during a datacenter network disruption. Which architectural component should the architect prioritize to meet these requirements?

Accepted Answer

Local Host Cache on the Delivery Controllers. Local Host Cache keeps a local copy of the site configuration and brokering data on each Delivery Controller, so sessions can still be brokered when the Controller cannot reach the SQL database. This is the component that directly preserves session launch capability during a datacenter network disruption affecting database connectivity.

Answer

Question 5

A Citrix architect is designing a Virtual Apps and Desktops environment that must support users in two regions. The architect plans to use a single Citrix Site with two zones. The company requires that users in each region connect to resources in their own region whenever possible, and that the solution remain functional if one region's Delivery Controllers fail. Which two design elements must the architect include to meet these requirements? (Choose two.)

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

Accepted Answer

Cache in RAM with overflow to disk. Cache in RAM with overflow to disk is the only MCS write cache type that can be configured to use a separate datastore for the overflow file while providing high performance. The other options either use local storage, which is not separate, or are not standard MCS write cache types. The persistence requirement is not met by any MCS write cache type, but the question's primary focus is on separate high-performance storage.

Answer

Cache on a shared datastore, non-persistent

Answer

Cache on a shared datastore, persistent

Answer

Cache on local storage

Question 6

An architect is designing a Citrix Virtual Apps and Desktops site for a company that wants to minimize the impact of a WAN outage between two data centers. Each data center will host a zone with its own Delivery Controllers and SQL Server. Which design decision best supports session brokering continuity in a satellite zone when the primary zone becomes unreachable?

Accepted Answer

Enable Local Host Cache on the satellite zone Delivery Controllers and ensure the satellite SQL Server is available.. Local Host Cache on satellite zone Delivery Controllers, combined with an available satellite SQL Server, lets the zone continue brokering sessions using a local copy of the configuration when the primary zone is unreachable. This design directly preserves session brokering during a WAN outage without depending on the failed link.

Answer

Deploy a second primary zone in the secondary data center and remove the satellite zone.

Answer

Place the site database on a shared storage device accessible from both data centers over the WAN.

Answer

Configure the satellite zone Delivery Controllers to use the primary zone SQL Server as their only database connection.

Question 7

A Citrix architect is evaluating the use of the Citrix Cloud Connector. What is the primary architectural function of the Cloud Connector in a Citrix DaaS deployment?

Accepted Answer

Proxying traffic to Citrix Cloud. The Cloud Connector acts as the communication bridge between the customer's on-premises resource location and the Citrix Cloud control plane. It facilitates the registration of VDAs, management of identities, and proxying of traffic, all while ensuring that no inbound firewall ports need to be opened. This architecture allows for secure, simplified management of resources while maintaining full control over the infrastructure, which is vital for enterprise-grade security and compliance.

Question 9

Which TWO components are essential for the operation of the Citrix 'Local Host Cache' feature?

Accepted Answer

Delivery Controller. Local Host Cache (LHC) requires a Delivery Controller and a local SQL database instance (specifically, the local SQL Express database that is automatically installed on the controller). These two components work in tandem to ensure that if the connection to the primary SQL site database is lost, the controller can continue to broker connections based on the locally cached state, preventing complete site downtime for connected users during a database outage.

StoreFront Server

Answer

NetScaler Gateway

Question 10

An architect is designing a high-availability architecture for the StoreFront layer. What is the recommended method to balance traffic across multiple StoreFront servers?

Accepted Answer

Citrix NetScaler ADC. Using a Load Balancer (such as a NetScaler ADC) is the standard best practice for providing high availability and persistence at the StoreFront tier. It ensures that user traffic is distributed evenly across available servers and that session persistence is maintained during the authentication and enumeration process. This design is critical for scaling to thousands of users while ensuring that no single StoreFront server becomes a bottleneck or a single point of failure.

Question 13

Refer to the exhibit. An administrator is troubleshooting a connection failure. Based on the output, what is the impact on the Site when the SQL server is unreachable?

Accepted Answer

The Controller will use the local SQL Express instance to broker sessions.. With Local Host Cache (LHC) enabled, the Delivery Controller can continue to broker sessions and handle connections even if the Site database is unreachable. The Controller uses a local SQL Server Express instance to cache configuration data, allowing limited operations. This architecture is vital for maintaining high availability, ensuring that users can still launch resources during a database outage, preventing a total system shutdown while the primary backend database is being restored.

Answer

The Site will go into maintenance mode and block all connections.

Answer

The Site will stop accepting new session launches until the database is back.

Answer

The Controller will fail to communicate with the License Server.

Question 14

Which component in a Citrix Virtual Apps and Desktops architecture is responsible for managing user sessions, authenticating users, and brokering connections to resources?

Accepted Answer

Delivery Controller. The Delivery Controller is the central management component of the Site, handling all session brokering and user authentication. It acts as the brain of the environment, coordinating communications between components like StoreFront and VDAs. Understanding this role is fundamental for architecture design, as it dictates how traffic flows and where authentication occurs, ensuring that users are connected to the correct resources based on their specific policies and identity.

Answer

StoreFront

Question 15

A Citrix architect is planning the deployment of StoreFront servers. Which design principle should be followed to ensure high availability for internal user access?

Accepted Answer

Use a StoreFront server group behind a load balancer.. Deploying multiple StoreFront servers in a server group behind a load balancer is the standard architectural approach for high availability. This configuration ensures that if one server fails, the others continue to serve requests, preventing a single point of failure. Proper configuration of load balancing also allows for efficient resource distribution, which is critical for providing a consistent, responsive access experience to all users within the corporate network.

Answer

Install StoreFront on the same server as the Delivery Controller.

Answer
