Arcitura Education S90.18 Exam - Topic 1 Question 101 Discussion

Actual exam question for Arcitura Education's S90.18 exam

Question #: 101
Topic #: 1

You are responsible for designing Service A, which must compose Services B and C. You are able to apply the necessary security mechanisms to ensure that messages exchanged by Service A comply with your security requirements. However, you are not given access to the design specifications for Services B and C. Based on the information that is published about Services B and C, you cannot guarantee that these services will provide the same level of security as Service A . This limitation was placed upon you as a result of the application of which service-orientation principle?

BService Autonomy

Surprised that we can't ensure security just because of abstraction!

I think it's Service Loose Coupling, but I'm not 100% on that.

Wait, are we sure it's not Service Autonomy? Seems like a gray area.

Totally agree, abstraction means we can't guarantee security levels.

It's definitely about Service Abstraction. Can't see the internals!

I keep mixing up the principles, but I think Service Autonomy makes sense here because it highlights the independence of services in terms of design and security.

I practiced a similar question about service dependencies, and I think the answer is Service Loose Coupling since it emphasizes independence between services.

I'm not entirely sure, but I feel like it could also be about Service Abstraction because we don't have full visibility into Services B and C.

I remember studying the principles of service orientation, and I think this might relate to Service Autonomy since I can't control the other services' security.

I think the key here is the security aspect. Since we can't control the security of Services B and C, that suggests the principle of Service Abstraction. We're abstracting away the internal details of those services, which limits our ability to ensure consistent security.

Okay, let me break this down. We have Service A that needs to compose Services B and C, but we can't guarantee the same level of security. This limitation is due to one of the service-orientation principles. I'm leaning towards Service Autonomy, since the services seem to be operating independently.

Hmm, I'm a bit confused by this one. The question mentions security requirements, but it's not clear how that relates to the service-orientation principles. I'll need to think this through carefully.

This question seems straightforward. I think the answer is Service Abstraction, since the question mentions that you're not given access to the design specifications for Services B and C, which is a key principle of service abstraction.

This is a tricky one. I'm not entirely sure, but I'm going to go with Service Abstraction. The question mentions that we're not given access to the design specifications, which seems to fit with the idea of abstracting away the internal details of the services.

I'm a bit confused by the wording of the question. Are we looking for the "easiest" way, or the most efficient? I might need to review the documentation on the different loop options to make sure I'm choosing the right one.

Can we just glue Service A, B, and C together and call it a day? No security issues if there's no separation, right? Just kidding, I'm going with D. Service Abstraction, the only way to keep our sanity.

Hold up, did they say we can't access the design specs? That's like telling a mechanic to fix a car without letting them see the engine. Gotta be D. Service Abstraction, right?

I think the answer is D. Service Abstraction. We're not given access to the design specs for Services B and C, so we can't guarantee their security level. Abstraction is the way to go here.
