1Y0-312 Advanced Site Architecture Practice Question
A Citrix architect is designing a Citrix Virtual Apps and Desktops 7 site that uses a multi-zone layout with a Primary Zone and two Satellite Zones. The architect must ensure that the site remains manageable if the Primary Zone becomes completely unavailable, including the Delivery Controllers and the Site database. Which statement describes the correct behavior of the site in this scenario?
⚠ Common exam trap
The trap here is believing that Satellite Zone Controllers can take over the database role or that brokering stops entirely without the database.
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
✓
Satellite Zone Delivery Controllers can continue to broker sessions using their Local Host Cache, but configuration changes are not possible until the Primary Zone or database is restored
Delivery Controllers use Local Host Cache to keep brokering sessions when the Site database cannot be reached. In a multi-zone site, Satellite Zone Controllers can continue to authenticate and launch sessions from their cached data. Administrative tasks that write to the database, such as configuration changes, are unavailable until the database is restored, so management capability is reduced but session delivery continues.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
All session brokering stops immediately because the Site database is the single point of failure for the entire site
Why it's wrong here
The Site database is critical for configuration and monitoring, but Local Host Cache allows brokering to continue when the database is unavailable. Controllers synchronize LHC periodically and can use it to launch sessions. Saying brokering stops immediately ignores LHC, which is specifically designed to maintain availability during database outages.
- ✓
Satellite Zone Delivery Controllers can continue to broker sessions using their Local Host Cache, but configuration changes are not possible until the Primary Zone or database is restored
Why this is correct
Local Host Cache on each Delivery Controller caches the brokering data needed to launch and maintain sessions. When the Site database is unreachable, Controllers enter LHC mode and continue brokering existing and new sessions for up to the configured duration. However, administrative changes such as creating Delivery Groups or editing policies require the database, so they are unavailable until it returns.
- ✗
Satellite Zone Delivery Controllers automatically promote themselves to Primary Zone Controllers and take over database writes
Why it's wrong here
Citrix Delivery Controllers do not have an automatic Primary Zone promotion mechanism. The Primary Zone designation is configured, and the Site database is a single logical database that Controllers connect to. There is no built-in role transfer that lets a Satellite Zone Controller become the database owner, so this behavior does not exist in the product.
- ✗
StoreFront automatically redirects users to a different site that shares the same database
Why it's wrong here
StoreFront does not perform cross-site redirection based on database availability. A StoreFront store is bound to specific Delivery Controllers within a site. If those Controllers are unreachable, StoreFront fails over to other Controllers listed in the store, but it does not discover or redirect to a separate site with its own database.
