1Y0-204 Architecture Practice Question
A company is deploying Citrix Virtual Apps and Desktops on-premises with two data centers. The design must ensure that users continue to launch published applications even if the SQL Server hosting the site database becomes unavailable for an extended period. Which architectural component must be enabled to meet this requirement?
⚠ Common exam trap
The trap here is assuming that database mirroring or Always On is required for Citrix to survive a database outage, when Local Host Cache is the native Citrix feature designed for that purpose.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Local Host Cache
Local Host Cache enables a Delivery Controller to broker connections using a local cache when the site database is unavailable. It synchronizes with the database and allows users to launch applications for a limited period. This directly addresses the requirement of continued application launches during a SQL Server outage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Zone Preference
Why it's wrong here
Zone Preference is used to direct users to the most appropriate zone based on network latency, user location, or tags. It does not provide any database outage resilience and will not help if the SQL Server is down. It is purely a routing mechanism, not a high-availability feature for the database.
- ✓
Local Host Cache
Why this is correct
Local Host Cache allows a Delivery Controller to continue brokering connections when the site database is unavailable by using a local copy of the configuration. It maintains a synchronized cache of the site data and supports failover for up to 96 hours, ensuring users can still launch published applications during a database outage.
- ✗
StoreFront server group
Why it's wrong here
A StoreFront server group provides load balancing and redundancy for the web front end. It does not address database availability or allow Delivery Controllers to broker connections when the SQL Server is offline. StoreFront would still fail to enumerate resources if the Delivery Controllers cannot access the database.
- ✗
SQL Server Always On availability group
Why it's wrong here
While SQL Always On can provide database high availability, it is not a Citrix Virtual Apps and Desktops architectural component. The question asks for a component within the Citrix solution that allows continued operation during a database outage. Local Host Cache is the built-in Citrix feature for this purpose.
