1Y0-204 Architecture Practice Question
A Citrix architect is designing a new Citrix Virtual Apps and Desktops deployment for a company with two data centers. The company wants to ensure that users can access their applications and desktops even if the connection between the data centers fails. The architect plans to use a single Citrix Site spanning both data centers. Which Citrix component should be deployed in each data center to provide local host cache and maintain user access during a database outage?
⚠ Common exam trap
Candidates often confuse Local Host Cache with other high-availability features like StoreFront load balancing or database mirroring, which do not provide the same local brokering capability.
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
✓
Delivery Controller
Local Host Cache is a feature of the Delivery Controller that enables continued operation when the site database is inaccessible. By deploying a Delivery Controller in each data center, the architect ensures that if the database or the connection to it fails, the local Delivery Controller can still broker connections using its cached configuration. This provides high availability and maintains user access during a database outage, which is the key requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SQL Server
Why it's wrong here
SQL Server hosts the site database, which is a critical component. However, Local Host Cache is a feature of the Delivery Controller that caches data locally when the database is unavailable. Simply deploying SQL Server in each data center does not provide LHC; in fact, the database itself is the component that may become unavailable. Therefore, this option does not meet the requirement.
- ✗
Citrix Gateway
Why it's wrong here
Citrix Gateway provides secure remote access but does not include local host cache functionality. It relies on StoreFront and Delivery Controllers for authentication and resource enumeration. Without a functioning Delivery Controller, Citrix Gateway cannot broker sessions. Thus, deploying Citrix Gateway in each data center does not address the need for local host cache during a database outage.
- ✗
StoreFront server
Why it's wrong here
StoreFront is responsible for authenticating users and enumerating resources, but it does not provide local host cache. During a database outage, StoreFront would rely on the Delivery Controller, which may be unavailable. StoreFront alone cannot maintain user access without a functioning Delivery Controller. Therefore, deploying StoreFront in each data center does not satisfy the requirement for local host cache.
- ✓
Delivery Controller
Why this is correct
The Delivery Controller is the component that provides Local Host Cache (LHC). When the site database becomes unavailable, LHC allows the Delivery Controller to continue brokering connections using a local copy of the configuration. Deploying a Delivery Controller in each data center ensures that if the connection between data centers fails, local users can still access resources. This directly meets the requirement.
