What is the primary focus of recoverability testing?

Ensuring the system continues operating during a fault

Verifying the system can restore data and operations after a failure

Assessing the system's ability to avoid failures

Measuring the system's availability percentage

What is the primary goal of fault tolerance testing?

To measure the average time to restore service after a failure

To verify the system continues to operate correctly in the presence of faults

To ensure the system never experiences any faults

To verify that the system fails gracefully and shuts down safely

A company's customer relationship management (CRM) system must be able to restore data from backups within 2 hours of a failure. The test team is planning recoverability testing. Which test should be included in the plan?

Verify that the CRM system can be accessed after a failure.

Restore the CRM database from a backup and measure the time taken to complete the restore.

Verify that the backup process runs automatically every night.

Verify that the backup files are stored in a secure location.

A software product is in the final stages of development, and the test team has only two weeks to conduct reliability testing. The product must have a failure rate of less than 0.5% per hour. The team has no historical reliability data. What is the most appropriate approach?

Conduct only fault tolerance testing, since it is more important.

Skip reliability testing and rely on the development team's confidence.

Conduct a full 2-week continuous test and count failures.

Conduct a focused reliability test using accelerated testing techniques to estimate the failure rate.

Which of the following is a typical activity in recoverability testing?

Calculating the mean time between failures

Testing the restoration of data from a backup

Measuring the percentage of time the system is up

Injecting a network fault to see if the system continues operating

Reliability Testing CTAL-TTA Practice Questions (Page 4)

Part of the Domain 4: Quality Characteristics for Technical Testing domain, which makes up ~14% of our current practice bank. ISTQB does not publish an official question count, but from its 120-minute exam (~50–80 total, ~7–11 in this domain), expect 1–2 from this objective — we provide 20 practice questions to prepare you well beyond it.
