ISTQB ATM Exam - Topic 1 Question 21 Discussion

Actual exam question for ISTQB's ATM exam

Question #: 21
Topic #: 1

You are managing the system testing for a SOA based system. The integrated system consists of several subsystems:

- A SOA middleware

- A CRM (Customer Relationship Management) system

- A BRM (Billing and Revenue Management) system

- A SMS (Subscriber Management System) system and you performed a risk analysis based on these subsystems.

At the end of the scheduled period for test execution you produce a first classical report based on the traditional metrics of testing. Test pass/fail status and bug status (open/resolved) That table provides you a distorted picture of the quality risk, because there is no indication of the risk level of the failed tests, the tests not run, or the open bugs. Thus, you produce the following table to solve this distortion issue:

In the table above, where you have introduced the concept of risk weighting, the highest risk test or bug report has a score of 1, while the lowest risk test or bug report has a score of 0.04. Which of the following subsystems, based on the risk scores of the table, is most risky? K4 3 credits

I’m surprised the SMS system isn’t flagged as more risky!

BRM has a lot of financial implications, so it could be high risk too.

Wait, are we sure about that? I thought SOA would be riskier!

Totally agree, CRM usually has a lot of user interactions.

I think the CRM system is the most risky based on the scores.

If I remember correctly, the SOA middleware often has a lot of dependencies, which could lead to higher risk, but I need to double-check the risk scores from the table.

I feel like the BRM system might be the most risky based on its impact on billing processes, but I can't recall the exact scores from our study materials.

I think we practiced a similar question about risk assessment in SOA systems, and I want to say it was the CRM that had the highest risk, but I could be wrong.

I remember we discussed how risk weighting can change the perception of test results, but I'm not sure which subsystem had the highest risk score.

Okay, I think I've got this. For a qualitative measure, I could talk about the reputation and stakeholder perception of the organization. And for quantitative, maybe the amount of funding they donate or number of training courses they provide.

I feel pretty confident about link aggregation, so I'm ready to tackle this question. Time to select the two correct statements.

I'm a little confused by this question. The measures described seem to span multiple layers of defense, from physical to perimeter to host. I'll have to review my notes on the defense-in-depth model to make sure I understand which layer this is targeting.

I remember we discussed rules for Time Frame in Audiences in class, but I can't recall if they actually create recurring activities.

Wait, the SMS system has a max score of 1.0? Looks like someone's been texting a little too much during testing. Time to put the phones down and focus!

The BRM system seems to be the most risky, with a max score of 0.8. Time to break out the crystal ball and see if we can predict any billing nightmares ahead!

Ah, the good old 'risk weighting' approach. No more distorted pictures, just cold, hard risk numbers. Now I can really dive in and figure out which system is giving the dev team the biggest headache.

Looks like the SMS system has the highest risk score, with a max of 1.0. Gotta keep a close eye on that one, no room for any SMS mishaps!

I think we should allocate more resources to testing the SMS system to ensure its stability in the integrated system.

It's crucial to address any issues in the SMS system before they escalate. Let's prioritize testing for it.

Hmm, the table shows the risk scores for the different subsystems. If the highest risk test or bug report has a score of 1, then the subsystem with the highest overall risk score is the one to focus on.
