Simulation test
Why wrong: Simulation tests specific scenarios but not necessarily with live transactions.
- B
Full interruption test
Why wrong: Full interruption shuts down the primary site, which is more risky.
- C
Tabletop test
Why wrong: Tabletop is a discussion-based exercise.
- D
Parallel test
Parallel test involves running both sites concurrently.

CISA Practice Question: Information Systems Operations and Business Resilience
This CISA practice question tests your understanding of information systems operations and business resilience. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which type of disaster recovery test involves actually switching over to the alternate site and processing live transactions, but does not require the primary site to be shut down?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"primary"Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.

Correct answer & explanation
✓
Parallel test
Parallel testing is the correct answer because it involves processing live transactions at the alternate site while the primary site remains fully operational. This allows validation of the disaster recovery (DR) systems without risking a service outage, as both sites run concurrently and results are compared for consistency. Unlike a full interruption test, the primary site is not shut down, ensuring business continuity during the test.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse parallel testing with a full interruption test, mistakenly thinking that any test involving live transactions must require shutting down the primary site, but parallel testing explicitly avoids that by running both sites concurrently.

Scenario analysis trap
Simulation tests specific scenarios but not necessarily with live transactions.
Detailed technical explanation
How to think about this question
In a parallel test, the alternate site is configured as a hot standby with synchronized data replication, often using technologies like synchronous replication (e.g., Oracle Data Guard with SYNC transport) or asynchronous replication with near-real-time lag. The test validates that the alternate site can handle production workloads and that data integrity is maintained, typically by comparing transaction logs or database checksums between sites. This approach is critical for organizations with zero recovery point objective (RPO) requirements, as it proves the DR site's readiness without risking primary site disruption.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CISA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
