The broker pattern is important, but not always necessary.

Wait, ease of implementation? Isn't that a bit too simplistic?
EL

Volatility of neighboring systems? That's a big one!

Totally agree, the expected amount of parallel calls is crucial too.

Gotta consider the protocols enforced by neighboring systems!

I practiced a question similar to this, and I think ease of implementation might be less critical than the other options.

I feel like the volatility of neighboring systems could be a factor too, especially if they change often.
KA

I'm not entirely sure, but I remember something about the expected amount of parallel calls being important for performance.

I think we need to consider the protocols enforced by neighboring systems, right? That seems crucial for compatibility.

I think the answer is Packet Mirroring, since it allows you to analyze network payloads and headers.

I think option B might be the right choice since I've seen it mentioned in the training materials about securing connections.

Parallel calls (D)? Psh, I just hope my interfaces can handle more than one user at a time without crashing.

The broker pattern (B)? Really? That's overkill for most external interface design. Let's keep it simple, folks.

Ease of implementation (E) is a bit of a wild card. Sometimes you have to sacrifice a bit of that for the more important technical considerations.

Volatility of neighboring systems (A) is crucial too. Can't have our interfaces breaking every time something changes on the other side!

F) Effect on the coupling in the building block view is another key factor to consider.
JO

C) Protocols enforced by neighbouring systems should also be taken into account.
BA

A) Volatility of neighbouring systems is definitely important to consider.
SA

Definitely need to consider the protocols enforced by neighboring systems (C), the expected amount of parallel calls (D), and the effect on the coupling in the building block view (F). These are critical factors in designing robust external interfaces.

I think ease of implementation should also be taken into account. It can affect the overall efficiency of the system.
JO

I agree with Beckie. Those factors are crucial for designing external interfaces.
BE

We need to consider volatility of neighbouring systems, protocols enforced by neighbouring systems, and expected amount of parallel calls.
