Exam OG0-091 topic 1 question 28 discussion

Catch here is "no operating characteristics change, which means no re-architecting". So answer is E: Simplification Change. There are three main categories of architecture change: 1. Simplification: this can be handled via change management techniques. 2. Incremental: this may be handled via change management techniques, or it may require partial rearchitecting. 3. Re-architecting: this requires putting the whole architecture through the architecture development cycle again.

https://pubs.opengroup.org/architecture/togaf8-doc/arch/chap14.html#tag_15_02_03 Guidelines for Maintenance versus Architecture Redesign: - If the change is at an infrastructure level - for example, ten systems reduced or changed to one system - this may not change the architecture above the physical layer, but it will change the Baseline Description of the Technology Architecture. This would be a simplification change handled via change management techniques.

E is correct - "If the change is at an infrastructure level - for example, ten systems reduced or changed to one system - this may not change the architecture above the physical layer, but it will change the Baseline Description of the Technology Architecture. This would be a simplification change handled via change management techniques."

each project need to have a business need, "server consolidation" planned for some reason!!

i prefer choose A: that not change application, But can change other IT Components, So we need to iterate on all ADM Phases
