1Y0-312 Advanced Site Architecture Practice Question
A Citrix architect is designing a multi-zone Site with a Primary Zone in New York and a Satellite Zone in London. The architect needs to ensure that session launch requests for London users are handled locally if the SQL database connection to the Primary Zone fails. Which configuration should the architect implement to meet this requirement?
⚠ Common exam trap
Candidates often overlook that Local Host Cache must be explicitly enabled on the Delivery Controllers; they may assume it is a default, always-on feature that requires no configuration in a multi-zone design.
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
✓
Enable Local Host Cache on the Delivery Controllers located within the Satellite Zone.
To ensure local session resiliency in a Satellite Zone, the architect must implement a Local Host Cache (LHC) configuration. When the connection to the Site database is interrupted, the Delivery Controllers in the Satellite Zone utilize the local SQL Express database to broker connections. This architecture minimizes downtime for users during WAN outages by allowing local resource enumeration and launch capabilities, effectively decoupling the Satellite Zone's brokering services from the Primary Zone's centralized database.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the SQL synchronization interval between the Primary and Satellite Zones to 60 minutes.
Why it's wrong here
The SQL synchronization interval is managed by the Site database and cannot be arbitrarily set to 60 minutes. Furthermore, simply adjusting synchronization intervals does not provide the failover mechanism required for session brokering during a complete database outage, as it does not enable the Local Host Cache functionality needed.
- ✗
Deploy a dedicated SQL database in the London zone and configure multi-site database mirroring.
Why it's wrong here
Citrix Virtual Apps and Desktops architecture does not support multi-site database mirroring for the main site database. The recommended design for zone-based resiliency is the Local Host Cache, which leverages local SQL Express instances rather than complex, unsupported cross-site database mirroring configurations that introduce unnecessary latency and management overhead.
- ✓
Enable Local Host Cache on the Delivery Controllers located within the Satellite Zone.
Why this is correct
Local Host Cache is specifically designed to allow Delivery Controllers to broker sessions when the connection to the central Site database is lost. By enabling this on the Satellite Zone controllers, the site ensures that local users can continue to launch resources using the cached information stored in the local SQL Express.
- ✗
Configure the Delivery Controllers in the Primary Zone to act as secondary brokers for the London zone.
Why it's wrong here
Configuring Primary Zone controllers as secondary brokers does not solve the underlying issue of WAN dependency during a database outage. If the primary database is unreachable, the primary controllers would also be unable to retrieve necessary site configuration data, rendering them ineffective as a reliable failover mechanism for the satellite.
