suggesting possible risks

Hello Ranchers

I am studying the risks of an architecture (part 2) and was wondering if you can help by suggesting possible risks that may occur commonly. Any possibility is welcome, since I'm just studying (I'm not making the risks of my project). I thought the following risks:
- Security - account hijacking.
- Communication with external systems - ensuring communication time
- Scalability - the system does not deal with the volume of access.
- Exchange of persistence mechanism - possible exchange for DBMS, NoSQL, LDAP or wherever (I really dont know if it is classified as risk ...)

Please suggest any others that may occur ...
Best regards.

The first three are good. I'm not sure I understand the last one.

People brainstorming risks comes close to collaborating on the assignment. Be careful about being specific.

That may be .... but it is still a form of study.

I'm not sure I understand the last one.

Exchange database - when would you design a solution that has a persistence layer that is not flexible to easily change the type of mechanism adopted. That would be a risk?

What are your suggestions for brainstorming risk ?

Best Regards.

Ah. That would be swapping out the database. Or not being tightly coupled to the database. That makes sense.

Google. Read books. The OCMJEA exam is not a brainstorming/group activity.

As I already said, I am not asking for help in my test, I'm not doing part 2 ...and this is not the kind of answer I expect this forum,......
Anyway ... thanks.
Could someone else help me with ideas?

While you may not be currently attempting the certification, there are others who are. Since they may be reading this forum, it would be wrong of us to allow such a discussion.

I do not agree with you. I believe we can talk about anything of OCMJEA, since that is not an assignment of specific candidate....
You guys look like they are turning this certification on a magical mystery ...
I really do not understand why ....
Anyway, thank you.

I think we should probably take a step back for a minute, and work out what we are discussing.

The original comment that started this meta-discussion was:

That still holds. You may want to read "IMPORTANT - Position on real assignment (Part 2) questions". This was following requests from Sun, and is still valid.

The end result is that:
  • If you are trying to understand something that is outside of your domain knowledge then it is reasonable to ask questions about the domain. The example given is that if you have an assignment that revolves around an airline reservation system, but you know nothing about airlines, then it is reasonable to ask what they mean by a "leg" of a flight.

  • If you are asking any question that contains the actual text from your assignment, or that the answer to your question could be copied / pasted into a submission, then it will not be allowed. It does not matter what your motivations for asking the question are - it matters whether someone can use the answer in their submission


It is that last point that causes the most issues, and that is affecting you. In the assignment, candidates have to talk about risks and mitigation strategies. In asking for people to "[suggest] possible risks", you may provide a real candidate with a list of risks that they may not have thought of. This could result in them passing the exam without having the knowledge themselves.

My understanding is that this is partially a problem with perception of who should be attempting to complete this assignment / get certified.
  • I believe Sun (Oracle) believes that they (Oracle) are stating that successful candidates are qualified to be architects. As such, collaboration is undesirable since many architects do not get that luxury in their full time jobs.

  • I believe that many of the real candidates are attempting the assignment / certification as a learning experience - something to help them become an architect one day. As a learning experience then collaboration is a good thing.


At the end of the day, Sun / Oracle own the certification, so it is their rules that apply. They have asked us not to allow collaboration on this certification, and that is what we have to do.

Ok Andrew ... Now I understand your point of view. That makes sense. I'm sorry.
Nice week end.
