Togaf Interview Questions and Answers

TOGAF Content Framework is also known as Architecture Content Framework. This framework provides a comprehensive model of architectural work products such as Architecture Building Blocks, Artifacts, Deliverables, and Artifacts within Deliverables. Content Framework promotes finer integration of work products. In this, the content meta-model is also included and dealt with. This framework mainly aims at greater consistency in the TOGAF outputs. Moreover, the Architecture Content framework provides a complete checklist of architecture outputs. 

Deliverables: These are the formal products that contain many artifacts. They are the outputs from a project and are contractually specified. 

Building Blocks: Building blocks are the components that can be amalgamated with other building blocks to deliver solutions and architectures.

Artifacts: Artifacts are fine-grain products that mainly present architecture from a particular viewpoint. They make up the content of the architecture repository. Artifacts are also classified into diagrams, catalogs, and matrices.

TOGAF provides two reference models. They are:

• The Integrated Information Infrastructure Reference Model: The Integrated Information Infrastructure Reference Model (III-RM) is the subset of TOGAF TRM. The components of TOGAF III-RM are taxonomy and III-RM Graphic.
• The TOGAF Technical Reference Model: It is a foundation architecture of generic functions and services. Within the Technical Reference Model, the foundation architecture is embodied and this provides a taxonomy of generic platform services and a model. This reference model is universally applicable and also can be used to build any kind of system architecture. TRM mainly contains two components one is Taxonomy and the other is TRM Graphic.

A Metamodel is known as the precise definition of the rules and constructs that are mainly needed for creating different models. Metamodeling is defined as a process in which the construction, analysis, and development of models, frames, etc. This helps in modeling a predefined bunch of problems. It acts as a precise definition for creating models. This model helps in describing how and what the architecture is presented in a structured way.

The core Metamodels entities are explained in detail:

• Data Entity: It is an encapsulation of data recognized by a business expert. Data entities can be structured based on the implementation considerations and can also be mixed with repositories, applications, and services. 
• Actor: A system or a person who is the outsider of the architecture model but keeps interacting with the model.
• Function: It delivers closely aligned business capabilities to an organization. 
• Business Service: This service mainly supports closely aligned business capabilities using an explicitly defined interface and it is also governed by the organization explicitly.
• Technology Component: It is defined as an encapsulation of technology infrastructure that mainly represents a specific technology product.
• Application Component: It is defined as an encapsulation of application functionality.
• Role: A role is an assumption for the actor to perform a task. 
• Platform Service: This service provides the technical strength required to enable infrastructure in order to support application delivery.
• Organization: It is a central unit for resources with goals and objectives. Organizations may also include business partner organizations or external parties. 

Architecture Capability Framework is developed and designed mainly to provide a group of reference materials to get an idea about how to establish an architecture function. Eventually, this framework is not intended to be a specific template for operating the capability of an enterprise architecture. 

The Architecture Capability Framework is structured in this way.

• Introduction
• Architecture Board
• Architecture Governance
• Establishes an Architecture Capability
• Architecture Compliance
• Architecture Skills Framework
• Architecture Maturity Models
• Architecture Contracts

The content metamodel plays a key role in providing definitions for all types of building blocks that may be present within an architecture, specifying how these building blocks are related to one another and described. The prominent feature of the content metamodel is it identifies all the concerns like business service, technology, entity, actor, data, and application and also lists out all the possible relationships among all the above concerns. Furthermore, it identifies the artifacts to represent concerns. 

In the context of TOGAF standards, the patterns are considered as the most common ways to arrange building blocks in a context. Patterns guide you about how, when, and why to use building blocks. SOA patterns play a crucial role in providing architectural guidance through anti-patterns and patterns. These patterns also help in building real SOA services that signify scalability, flexibility, and availability. 

The Enterprise Continuum is considered as the outermost continuum in TOGAF. This continuum is mainly used to classify the assets that are related to the context of enterprise architecture. The enterprise continuum provides a broader context for the TOGAF platform by explaining various scopes and types of architecture assets and artifacts that are leveraged and derived during its use. It also provides methods for classifying solution artifacts and architecture. The enterprise continuum is considered as a key essential to understand and communicate both between vendor organizations and customer enterprises and within individual enterprises. 

TOGAF Certification is considered as one of the best certifications in the current world. This certification is considered as the most important endorsement for professional development and also provides a clear path for enterprise architects. The TOGAF Certification course will cover all the basic and core concepts like Enterprise continuum, ADM phases, TOGAF Reference Models, Architecture Views, etc. TOGAF certification will help individuals to boost their careers and achieve goals. Qualifying TOGAF Certification will set you apart from peers and land you in the world where there are limitless opportunities. 

The essential components of Architecture Repository are listed below:

• Architecture Capability: This component mainly defines the processes, structures, and parameters that usually support the governance of the architecture repository. 
• Governance Log: This provides the record or list of governance activities within the enterprise.
• Architecture Landscape: This landscape provides the architectural representation of the assets deployed within the operating enterprise at a particular instance of time.  
• Solutions Landscape: This showcases an architectural representation of the SBBs that supports the architecture landscape deployed by the enterprise. 
• Standards Information Base: Its key role is to capture the standards by which the newly built architectures must comply. 
• Architecture Metamodel: This metamodel provides a clear explanation about the organizationally tailored application of an architecture framework. 
• Architecture Requirements Repository: Presents a clear view of all the authorized architecture requirements which are granted by the architecture board.
• Reference Library: Provides patterns, templates, guidelines, and other forms in order to speed up the creation of new architectures for the enterprise.  

The key benefits of architecture governance are as follows:

• Protects existing asset base by reusing the existing architectural components. 
• Controlled risk management 
• Implementation of management, monitoring, and proactive control mechanisms
• Reuse of component, concept, and process across all business units. 
• Value creation through feedback, monitoring, evaluation, and measuring. 
• Allows integration of existing processes and methodologies and also complements functionality by adding control capabilities.
• Ensures the level of visibility
