SSA questions well answered alreadypassed
Even if a formal specification does not exist, it is still correct to say every system has an architecture. -
correct answer ✔✔True
Scrum is one of the most popular approaches for Agile project management.
The Scrum process starts by electing issues from the sprint to compose a backlog. The backlog
corresponds to an iteration and it should last a pre-defined period of time, where those issues will be
addressed by the project team. At the end of the sprint, unfinished issues are returned to the sprint for
prioritization.
The status of each activity should be updated to the Scrum board. - correct answer ✔✔False. Elect issues
from backlog to compose sprint
Defining a structured solution to meet all technical and operational requirements of a system while
optimising its quality attributes. - correct answer ✔✔Software Systems Architecture
During a standup, each development team member volunteers the status of the activities under his or
her responsibility (completed, next steps, and roadblocks). - correct answer ✔✔Agile daily coordination
meetings
They have considerable impact on a system's quality. - correct answer ✔✔Architectural decisions
It can be used to manage computational resources on supercomputers and cloud environments. - correct
answer ✔✔DRMS. Distributed resource management system
Upon a user's request, the DRMS will allocate resources to the user, but only if such resources are
available, the resources are within the user's quota, and the user is allowed to work in that particular
environment (supercomputer or cloud). - correct answer ✔✔True
,A monitoring tool will be able to allocate resources on the distributed system managed by the DRMS. -
correct answer ✔✔False. The monitoring does not do the actual allocation
When requesting resources to a DRMS, the user needs to specify exactly what he or she wants in terms
of infrastructure (e.g., memory, computing, and storage). In some cases, it is also possible to specify
other requirements such as operating system. All users will get exactly the same resources regardless of
the environment, making the DRMS task rather simplistic in terms of resource allocation. - correct
answer ✔✔False. User get's requested resources.
Some of the assignment requirements (DRMS) will be similar to the requirements of Internet bankings
and other web systems, at least in terms of what matters to build system architectures. - correct answer
✔✔True
User Story - correct answer ✔✔A user story represents a small piece of business value that a team can
deliver in an Agile iteration; must have only enough information to guide the development; then it can
be incremented over time.
As a <user type>, I want to <function> so that <benefit> .
DRMS - correct answer ✔✔Distributed Resource Management System
Main Architectural Structures - correct answer ✔✔Module - code
Runtime/Component and Connector (C&C) - Interaction of structures at runtime
Allocation - Mapping the structures to the system's environments: where software is created and
executed (dev-ops, integration and testing)
There is no such thing as an inherently good or bad architectures - correct answer ✔✔True
Architectures are either more or less fit for some purpose - correct answer ✔✔True
Architectures can be evaluated but only in the context of
, specific stated goals - correct answer ✔✔True
System Requirements - correct answer ✔✔Functional requirements, Quality Attribute Requirements,
Constraints
Functional Requirements - correct answer ✔✔• State what the system must do or how it must behave or
react to run-time stimuli
• Functionality is the ability of a system to do the work for which it was intended
• Functionality does not determine architecture
Quality Attribute Requirements - correct answer ✔✔• Annotate (qualify) functional requirements
• Qualification might be how fast the function must be performed, how resilient it must be to erroneous
input, how easy the function is to learn, etc.
Constraints - correct answer ✔✔• Design decisions that have already been made for you
• They cannot be changed, so architecture has to be built on top of the constraints
ASR - correct answer ✔✔Architecturally Significant Requirements
Notations - correct answer ✔✔Informal - general purpose diagrams (powerpoint, etc)
Semi-formal - standardised notation (UML)
Formal - precise, mathematically- based notation (ADLs - Architecture Description Languages)
When creating user stories, it is important to name the user story and identify the user, the action and
the associated benefits. User stories also need to be validated, therefore adding acceptance criteria in
order to make sure the user story can indeed be moved to the "DONE" column in the Scrum board is
always welcome. - correct answer ✔✔True
The way an architecture is conceived will determine the quality attributes it can achieve. It's relationship
to quality attributes is the only reason why an architecture is important. - correct answer ✔✔False. it's
not the only reason?
