A Citrix Engineer needs to design a multi-node, scalable XenMobile solution. Which database type should the engineer choose to meet the needs of this deployment?

Toby R.Jan 13, 2026

For a multi-node, scalable XenMobile deployment, the answer is A, Microsoft SQL. XenMobile only supports Microsoft SQL Server for production deployments with multiple nodes, so PostgreSQL (which is the embedded single-node option) and the other databases are simply not supported in that context.

SQL Server only, not generic "Microsoft SQL" but yeah, pick A.

Thought B was right until I remembered multi-node XenMobile scales on SQL Server only.

Saw this exact question on my 1Y0-371, knew it cold from building a lab first: SQL Server is the only supported database for multi-node XenMobile, so A is your pick.

Think of your database like the foundation of a house. A single-room cabin can sit on plain concrete blocks, but the moment you start adding floors and wings, you need a poured, engineered slab that can carry the load without cracking. PostgreSQL is that engineered slab, built from the ground up to handle concurrent connections across multiple nodes without choking, which is exactly what a scaled-out XenMobile environment demands. The other options either carry licensing costs that balloon fast at enterprise scale or have replication quirks that make a multi-node XenMobile cluster fragile under real production traffic. I went back and forth on this one, but every practice scenario I worked through where the question mentioned scalability and multi-node pointed me right back to B, PostgreSQL, because it gives you the open-source reliability and connection-handling headroom that Citrix designs that architecture around.
