22. Which of the following are TRUE about a deployment diagram?
A.
Since there is always some kind of response to a message, the dependencies are two-way between deployment components.
B.
Dependencies between deployment components tend to be the same as the package dependencies.
C.
Deployment diagrams can used to show physical modules of code.
D.
Deployment diagrams can be used to show the physical distribution of a system across computers.
My answers: a, b, c
I can be sure about B and C. A and D are kind of ambiguous. What do you guys think?

My answer is D.
A is obviously wrong. If two components are mutually dependent, you should consider to put them together to form a new component.
B is logically wrong. As a component consists of a couple of packages, dependency between the two components does not imply that a package in one component depends on any package in another component.
C is nonsense in my point of view.

First, there doesn't need to be always a kind of response; second, I don't think that a response does imply a dependency in that direction.


B.
Dependencies between deployment components tend to be the same as the package dependencies.


I think this is somewhat true - if component A depends on component B, probably the packages deployed at component A also depend on (some of) the packages deployed at component B.


C.
Deployment diagrams can used to show physical modules of code.


What the hell are "physical modules of code"???


D.
Deployment diagrams can be used to show the physical distribution of a system across computers.


Certainly true. In fact, isn't that one of its main purposes?
