1Y0-204 Site Deployment and Configuration Practice Question
A Citrix administrator is preparing a new Citrix Virtual Apps and Desktops 7 Site that will use a single Microsoft SQL Server database for the Site configuration and monitoring. The SQL Server is on a separate VLAN, and the administrator wants to minimize the number of ports opened through the firewall between the Delivery Controllers and the SQL Server. Which port must be open on the firewall to allow the Delivery Controllers to communicate with the SQL Server by default?
⚠ Common exam trap
Test-takers frequently confuse the SQL Server default port with Oracle's default port or with common web service ports.
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
✓
TCP 1433
Microsoft SQL Server accepts client connections on TCP 1433 by default. The Delivery Controllers must reach the Site database on that port unless a custom port was assigned during SQL Server configuration. Therefore, opening TCP 1433 between the Delivery Controllers and the SQL Server satisfies the connectivity requirement while keeping firewall changes to a minimum.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
TCP 389
Why it's wrong here
TCP 389 is used for LDAP, typically to Active Directory domain controllers. While Citrix components may use LDAP for authentication and directory queries, this port is not used for the SQL database connection between Delivery Controllers and the SQL Server. Opening it would not satisfy the database connectivity requirement.
- ✗
TCP 8080
Why it's wrong here
TCP 8080 is commonly used as an alternative HTTP port for web servers or services, but it is not the default SQL Server database listener. The Citrix Delivery Controllers do not connect to the Site database over port 8080, so this would not enable the required communication through the firewall.
- ✗
TCP 1521
Why it's wrong here
TCP 1521 is the default listener port for Oracle Database, not Microsoft SQL Server. This Citrix Site uses a Microsoft SQL Server database, so opening this port would not permit the Delivery Controllers to reach the database. It is a plausible distractor for administrators who are more familiar with Oracle connectivity requirements.
- ✓
TCP 1433
Why this is correct
SQL Server listens by default on TCP port 1433 for client connections. The Delivery Controllers use the SQL Server Native Client to connect to the Site database on this port. Unless the SQL Server instance has been configured with a custom port, opening TCP 1433 between the Delivery Controllers and the SQL Server is sufficient for database communication.
