Discuss Arcitura Education S90.19 Exam Topic 6 Question 12

The Exception Shielding pattern was applied to the design of Service A . During testing, it is revealed that Service A is disclosing sensitive error information in one of its response messages. How is this possible?

AIt is the Message Screening pattern, not the Exception Shielding pattern that prevents a service from transmitting sensitive error information in response messages.

BThe Trusted Subsystem pattern has already been applied to Service A, thereby conflicting with the application of the Exception Shielding pattern.

CThe Exception Shielding pattern states that, in case of an error, the service should not send back any message at all, because this would implicitly tell the service consumer that something has gone wrong, thereby exposing vulnerabilities.

DNone of the above.

None of these options seem right to me.

Wait, so it can still leak info? That’s surprising!

I disagree, the Exception Shielding pattern should cover this.

Actually, it’s the Message Screening pattern that does that.

I thought Exception Shielding was supposed to prevent that!

Okay, let's see here. The key things I'm seeing are that we need to do step-by-step testing for all scenarios in a complex user interaction, and we need to be able to see the workflow while interacting with the chatbot. I think option B is the way to go here.

Hmm, I'm not totally sure about this one. The question is asking why this is the "appropriate" application of the Plans theme, which implies there may be other ways to apply it as well. I'll need to review the Plans theme in more detail to make sure I understand the nuances.

Ah, I remember learning about business impact analysis (BIA) in class. That seems like the best fit here, as it focuses on assessing the potential business impacts of the identified risks.

I'm a bit confused on this one. Is it possible that the answer could be "any of the above" since there are different settlement methods for different types of options? I'll have to review my notes to be sure.
