Architechture Characteristics

[s khosa]

Hi,

I came across this question in a mock test for SCEA:

As an architecht you are interested in the architechture characteristics of a system. Which TWO are architechtural characteristics:

A Scalability
B Reliablility
C Inheritence
D Performance

Correct answer is B and D

But i think it has to have 3 answers. Option A should also be a architechtural characteristic. Am i correct in my observation?

Thanks

1. Performance
2. Scalability
3. Reliability
4. Availability
5. Maintainability
6. Manageability
7. Security
