Arcitura Education S90.19 Exam - Topic 6 Question 54 Discussion

Actual exam question for Arcitura Education's S90.19 exam

Question #: 54
Topic #: 6

Service A retrieves data from third-party services that reside outside the organizational boundary. The quality of the data provided by these third-party services is not guaranteed. Service A contains exception shielding logic that checks all outgoing messages. It is discovered that service consumers are still sometimes receiving malicious content from Service A . Because digital signatures are being used, it is confirmed that Service A is, in fact, the sender of these messages and that the messages are not being altered by any intermediaries. Why do messages from Service A continue to contain malicious content?

AMessages received from third-party services are the likely source of the malicious content.

BDigital signatures alone are not sufficient. They need to be used in conjunction with asymmetric encryption in order to ensure that no intermediary can alter messages.

CException shielding logic needs to be used in conjunction with asymmetric encryption in order to guarantee that malicious content is not spread to service consumers.

DNone of the above.

I think we need more than just signatures and shielding.

Wait, are we sure it's not just a flaw in Service A?

Exception shielding alone isn't enough, right?

I agree, digital signatures don't stop malicious content.

Sounds like the third-party services are the problem.

I think option D could be a trick answer, but I’m not confident. It feels like one of the other options must be right.

I practiced a similar question where exception shielding was mentioned, but I can't recall if it was paired with encryption. Option C seems plausible, though.

I'm not entirely sure, but I feel like digital signatures alone might not be enough to prevent malicious content. Maybe option B is correct?

I remember discussing how third-party services can introduce vulnerabilities, so I think option A makes sense.

I've got a strategy for this. I'm going to carefully read through the code and think about how the progress bar is being updated. That should help me figure out the right answer.

Hmm, I'm a bit unsure about this one. I know the portfolio office is important, but I'm not totally clear on the reporting structure. I'll have to think this through carefully.

Wait, I think the PDCP layer rate could be the highest. That layer handles the encryption and compression, so the data rate might be the largest there.

Hmm, this seems straightforward enough. I just need to remember the formula for calculating excess equity.
