ISTQB CTAL-TTA Exam - Topic 6 Question 12 Discussion

Actual exam question for ISTQB's CTAL-TTA exam

Question #: 12
Topic #: 6

Your team is now accountable for the support and enhancement of a payroll system that has been in production for many years and modified by many different developers. It has been noticed by management that small functional enhancements take much longer than equivalent changes on more recently developed systems. You have been tasked with implementing improved testing approaches that will help to identify the root cause of this problem.

Which of the following is the best technique to apply in this scenario?

AOrthogonal arrays

BExploratory analysis

CStatic analysis

DData flow analysis

Show Suggested Answer

Suggested Answer: C

Static analysis is the best technique for identifying the root causes of issues in a legacy system where small functional enhancements take disproportionately long to implement. This technique involves examining the code without executing it to detect potential vulnerabilities, coding errors, and complexities. Static analysis can highlight problematic code segments and inefficient coding practices that may contribute to the increased time required for implementing changes, thereby assisting in addressing these systemic issues efficiently.

I’m surprised they didn’t mention exploratory analysis!

Data flow analysis might uncover hidden dependencies too.

I’m a bit confused about orthogonal arrays; I thought they were more for testing combinations rather than identifying root causes in legacy systems.

I feel like we practiced a question similar to this, and data flow analysis was mentioned as a way to track how data moves through the system.

I’m not entirely sure, but I think exploratory analysis might be useful for understanding the current state of the system.

I remember we discussed how older systems often have hidden complexities, so maybe static analysis could help uncover those issues.

Exploratory analysis could be a good starting point to get a better understanding of the system's behavior and identify any areas that might be causing issues. It's a more open-ended approach, but it could uncover some valuable insights.

Data flow analysis could also be a good option here. If the system has been modified by many different developers over the years, it might have some complex data dependencies that are causing problems.

Okay, I think I've got a handle on this. Static analysis seems like the way to go - it can help identify potential issues in the codebase that might be causing those delays in functional enhancements.

Hmm, I'm a bit unsure about this one. I'll need to review my notes on these testing techniques and try to figure out which one would be the best fit.

This seems like a tricky question. I'll need to think carefully about the different testing approaches and how they might apply to the given scenario.

Hmm, I'm a bit unsure on this one. There are a few different options that could potentially cause the out of space error. I'll need to carefully consider each of the answer choices and think through the specific ONTAP limits and capabilities.

Alright, let's think this through step-by-step. The question is asking about the actions we can perform using the Speed Status Change feature. That means these are likely common or frequently used actions, so I'll focus on the more straightforward options like changing the bank account or releasing vouchers for payment.

I feel like pressurized pumps were mentioned in the materials, but what if they don't actually fall under the RBI guidelines?

This payroll system sounds like a real Frankenstein's monster. I bet the developers who worked on it back in the day are all long gone, leaving the rest of us to clean up the mess. Good luck with that!

Exploratory analysis could be a good starting point, but I'd want to pair that with some more rigorous techniques like static analysis or data flow analysis to really get to the root of the problem.

Orthogonal arrays? Really? I think that's a bit overkill for this scenario. Keep it simple, focus on the fundamentals.

Static analysis seems like the way to go here. If the code has been modified by many different developers over the years, it's likely to have a lot of technical debt and hidden issues that need to be uncovered.
