A company is evaluating two architectures for a new application: a monolithic architecture and a microservices architecture. The application is expected to have variable load, with occasional spikes. Which architecture is more likely to have performance risks related to scaling?

Monolithic, because scaling the entire application is simple and efficient

Microservices, because scaling individual services can be complex and may introduce network overhead

Neither has scaling risks because they are both well-understood

Both have identical scaling risks

A financial services firm operates a client-server application where a central server processes transactions from thousands of remote clients. The server has a single database and a fixed number of worker threads. The team wants to validate that the system can handle the expected peak load without errors. Which performance testing focus is most critical for this architecture?

Endurance testing to check for memory leaks over a 24-hour period

Spike testing to see how the system handles sudden increases in load

Load testing to verify the server can handle the expected peak number of concurrent clients

Stress testing to find the breaking point beyond peak load

A team is performance testing a service-oriented architecture (SOA) with asynchronous messaging. They notice that the message queue depth is increasing, but the consumer services are underutilized. Which bottleneck is most likely?

The producers are sending too many messages

The network between producers and the queue is slow

The consumer services are not processing messages fast enough

Part of the Performance Testing in the Software Lifecycle domain, which makes up ~19% of our current practice bank. ISTQB does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–11 in this domain), expect 2–3 from this objective — we provide 26 practice questions to prepare you well beyond it.
