A database team is using a version control system to manage schema changes. They have a CI/CD pipeline that automatically deploys schema changes to a test environment. After a recent deployment, the application team reported that the application is failing because a required column is missing from a table. What is the most likely cause of this issue?

There is a network connectivity problem between the application and the database.

The database is not able to handle the application's load.

The schema change script was not validated against the application's expected schema before deployment.

The version control system is not being used correctly.

A DBA is working on a project where the schema is managed in a version control system. A new developer has joined the team and needs to set up a local development environment. What is the best way for the developer to get the correct schema?

Ask another developer to export their local database.

Create a new database and manually create the tables based on the design document.

Check out the latest schema scripts from version control and apply them to a new local database.

Copy the schema from the production database.

A new web application has been deployed to a test server. The application is failing to connect to the database. The DBA has confirmed that the database service is running and listening on the expected port. What should the DBA check next to troubleshoot the connectivity issue?

Verify that the connection string in the application is correct and that network firewalls allow traffic on the database port.

Run a stress test on the database to see if it can handle the application's load.

Review the database schema to ensure it matches the application's expectations.

Check the version control system for the latest application code.

Which tool is commonly used to manage version control for database schema scripts?

SQL Server Management Studio (SSMS)

A DBA is deploying a new schema to a test environment. The application team has provided a script that creates the schema. After running the script, the DBA notices that a foreign key constraint is missing. The application team insists the script is correct. What is the most effective way for the DBA to resolve this discrepancy?

Check the database connectivity from the application to the test database.

Manually add the missing foreign key constraint to the test database.

Run a stress test to see if the missing constraint affects performance.

Use a schema comparison tool to compare the deployed schema against the application team's expected schema or a baseline.
