Citrix Virtual Apps and Desktops 7 Advanced Configure and Manage — Question 35

Scenario: A Citrix Engineer is working on a Citrix Virtual Apps and Desktops deployment.
The current setup has the following characteristics:
✑ Three data centers (A, B, and C), each with a large user base.
✑ Network latency between these datacenters is more than 300 ms RTT because they are located at geographically far distances.
Which design should the engineer choose to ensure optimum performance?

Answer options

• A. A Multi-zone site with three zones (one primary and two secondary), with a site database in each of the three zones
• B. A Multi-zone site with three zones (one primary and two secondary), with a site database in the Primary zone
• C. One site for each data center with a common site database deployed at the largest site
• D. One site for each data center with a separate site database for each site

Correct answer: D

Explanation

The correct answer is D because having a separate site database for each data center minimizes the impact of latency since each site operates independently. Options A and B would introduce a single point of failure and increased latency due to reliance on a centralized database. Option C may lead to performance issues as well, given the high latency affecting all data centers trying to access a common database.
