Have you prepared to attend the job interview? Are you confused in job preparation? Then no problem we have the right solution you in in our site page. Underneath are the commonly asked Advanced Software Architecture and Design interview questions and answers which can make you feel relaxed to face the interviews :. Question 1. Answer : Adopting a product line paradigm creates an organizational shift.
Managing product line evolution is the most difficult part of the paradigm. The product line will change as new versions of the current product come out.
An organization would need to use the new versions to satisfy changing client needs. Additionally, new improvements to various components may change the way the products are built. New version of components may not be entirely backward compatible, thus additional rework will need to be done to accommodate the changes. Question 2. Answer : The blackboard framework is a dynamic group of independent entities that communicate and work together in order to solve some common problem.
There is no centralized control mechanism that makes decisions as to when a knowledge source needs to contribute some piece of information. Rather the control entity states the conditions of when and each knowledge source need to contribute. The knowledge sources observe the commotion on the blackboard and contribute to progress independently.
Question 3. Answer : The blackboard model is usually composed of three components: knowledge sources, blackboard data structure, and control. The knowledge source component represents the chunks of information that is needed in order to solve a problem. These sources are separate from each other. The blackboard data structure can be looked at as a repository for the final solution.
In this storage receptacle the final solution is slowly developed based on the sources and controls used. The control is not a module, but rather a mechanism or an abstract algorithm that specifies how a problem will be solved.
Question 4. Answer : A collection of assets includes the following elements:. Question 5. Answer : The main function of the High Level Architecture is to establish a common infrastructure, or the foundation, for a building other components of a system.
The infrastructure is then used and re-used by other components of a system that rely on communication and other resources through HLA. This non-software blueprint of a system has been used by the AMG to create an environment that supports interoperability and reusability.
Interface specification is used to coordinate communication efforts of various components that are built on top of the HLA. Question 6. When Is Middleware Not Appropriate? Answer : Middleware can get very complex and difficult to develop. The difficulties arise from the need to know the location of the servers and the amount of low-level details exposed. Certain domain specific systems with hard real-time systems may not afford to use a middleware services as that may slow down transaction speeds between an OS and applications.
Question 7. If an identify of an object changes, then all other objects that use that identify must be updated in order to reflect the change in just one object. Manageability of various objects becomes a major issue. Question 8. Is Such A Feature Desirable? Answer : Yes, an object can have multiple interfaces.
From an architectural point of view there are advantages to having multiple interfaces. Because an object preserves the integrity of data it contains, the only way to send messages to that object is via interfaces.
Thus if some object A wants to communicate with some other object B, then it has to talk through an interface. One interface does not fit the needs of all objects, thus it is useful to have multiple interfaces to promote communication between different objects that have different requirements. Question 9. Answer : The activity of a filter is triggered when there is information to be processed. When the pipe runs dry and no information is incoming a filter may fall asleep until more information arrives.
Additionally, feedback and feedforward controls are responsible for continuing feeding information back into a filter.
Question Answer : Software defects that lead to security problems come in two major flavors :. Implementation bugs in code account for at least half of the overall software security problem.
The other half involves a different kind of software defect occurring at the design level. It is far more cost-effective to identify and remediate design flaws early in the design process than to patch flawed design implementations after deployment. They take less time to conduct and can be carried out by a much larger talent pool than traditional ARA reviews. Most importantly, the lightweight approach is efficient enough that it can be scaled to cover an entire application portfolio.
Organizations failing to integrate architecture and design reviews in the development process are often surprised to find that their software suffers from systemic faults both at the design level and in the implementation. In many cases, the defects uncovered in penetration testing could have been identified more easily through other techniques—earlier in the life cycle. Testers who use architecture analysis results to direct their work often reap greater benefit.
Answer : Software architecture exposes the structure of a system while hiding the implementation details. Architecture also focuses on how the elements and components within a system interact with one other. Software design delves deeper into the implementation details of the system. Design concerns include the selection of data structures and algorithms, or the implementation details of individual components.
Architecture and design concerns often overlap. Rather than use hard and fast rules to distinguish between architecture and design, it makes sense to combine them. In some cases, decisions are clearly more architectural in nature. In other cases, decisions focus heavily on design and how it helps to realize that architecture.
An important detail to note is that architecture is design, but not all design is architectural. In practice, the architect is the one who draws the line between software architecture architectural design and detailed design non-architectural design. There are no rules or guidelines that fit all cases—although, there have been attempts to formalize the distinction.
Current trends in software architecture assume that the design evolves over time and that a software architect cannot know everything up front to fully architect a system.
The design generally evolves during the implementation stages of the system. The software architect continuously learns and tests the design against real world requirements. What Is Software Design? Answer : Software design is the process of conceptualizing the software requirements into software implementation. This is the initial phase within the software development life cycle SDLC —shifting the concentration from the problem to the solution.
When conceptualizing the software, the design process establishes a plan that takes the user requirements as challenges and works to identify optimum solutions. The plan should determine the best possible design for implementing the intended solution. Software design includes all activities that aid in the transformation from requirement specification to implementation. These requirements should be clear, actionable, measurable, and traceable to business requirements.
Requirements should also define how the software should interact with humans, hardware, and other systems. This high-level design perspective focuses on how the system, along with all its components, implements in the form of modules. It recognizes the modular structure of each sub-system and their interaction among one another.
Detailed design: Detailed design involves the implementation of what is visible as a system and its sub-systems in a high-level design. This activity is more detailed towards modules and their implementations. It defines a logical structure of each module and their interfaces to communicate with other modules. What Is Software Architecture? A system represents the collection of components that accomplish a specific function or set of functions.
In other words, the software architecture provides a sturdy foundation on which software can be built. A series of architecture decisions and trade-offs impact quality, performance, maintainability, and overall success of the system. Failing to consider common problems and long-term consequences can put your system at risk.
There are multiple high-level architecture patterns and principles commonly used in modern systems. These are often referred to as architectural styles. The architecture of a software system is rarely limited to a single architectural style. Instead, a combination of styles often make up the complete system. How Do Engineering Disciplines Evolve? Answer : The engineering disciplines evolve from ad hoc state in two steps. Initially, talented and passionate amateurs pioneer the discipline.
They achieve their goals by all means necessary — usually irrationally using available resources.
Follow along and check 45 most commonly asked Software Architect Interview Questions and Answers for experienced developers to know before your next senior technical interview. This states that it is not possible for a distributed computer system to simultaneously provide all three of the following guarantees:. The CAP acronym corresponds to these three guarantees. This theorem has created the base for modern distributed computing approaches. Worlds most high volume traffic companies e. Amazon, Google, Facebook use this as basis for deciding their application architecture. It's important to understand that only two of these three conditions can be guaranteed to be met by a system.
Solutions architects are professionals who are responsible for solving certain business problems and completing projects. Businesses today rely on the expertise of solutions architects to recommend and manage hardware and software systems that are central to operations. For this reason, people with technical acumen and development skills may look into becoming a solution architect. In this article, we'll provide the top 35 solution architect interview questions to expect during a job interview with example answers.
Software Architect Interview Preparation Guide. Ten years? Bad Answer: A generic or uninspired answer.
Experts often agree that you should aim for the best fit for an architecture position long-term rather than the best software architect who knows the particular programming language you need. Languages can be learned quickly by skilled architects, so it helps to seek candidates that have a diverse education and have sought to continue bettering themselves beyond the structure of a university curriculum. What to look for in an answer:.
If you are a software engineer with many years of experience under your belt and are looking for the next step in your career, one of the options you could take is to apply for a Technical Architect position. Interview process for this position is generally different compared to a software developer interview. You will need to show a different set of skills, which are usually not required for an engineering position, so you might want to practice them in order to display your best knowledge. I have worked as a Technical Architect for a numerous companies and went through this process multiple times myself. I was also involved in the hiring process for new Technical Architects, so I know how this process looks like.
