   A test analyst is analyzing the results of a performance test. The application has a response time of 2 seconds at 100 concurrent users, but at 200 concurrent users, the response time jumps to 8 seconds. The application server's CPU is at 60% at 200 users, and the database server's CPU is at 95%. The test analyst suspects a bottleneck. What is the most likely cause?

   • AThe database server is saturated, causing a queue of queries.
   • BThe application has a memory leak that degrades performance over time.
   • CThe application server is not configured to handle more than 100 concurrent users.
   • DThe network bandwidth is limited.

   A technical test analyst is reviewing code for a new REST API that will handle high concurrency. During a static code review, they notice that every request creates a new database connection and closes it at the end of the request. The team is concerned about performance under load. Which static analysis finding is most likely to be a performance bottleneck?

   • AThe code lacks input validation, which could lead to SQL injection.
   • BThe code uses an ORM that generates complex SQL queries.
   • CThe code creates a new database connection per request without reusing connections.
   • DThe code uses a connection pool, but the pool size is set to 10.
