Mixed Deck — All CEA Topics Flashcards

A key business stakeholder consistently rejects architecture proposals. What should the enterprise architect do FIRST?

Answer: Conduct a stakeholder interview to understand their concerns and priorities

Understanding the stakeholder's underlying concerns through direct conversation is the first step to resolving resistance.

How are work packages typically organized when creating an EA Implementation and Migration Plan?

Answer: As prioritized projects and programs linked to the Architecture Roadmap

Work packages in an EA Implementation and Migration Plan are organized as prioritized projects and programs that are directly linked to the Architecture Roadmap, ensuring alignment with the transition strategy.

An enterprise architect is designing a hybrid cloud environment. Which security pattern BEST ensures consistent policy enforcement across on-premises and cloud workloads?

Answer: Implementing a unified Security Policy Management framework with centralized enforcement across all environments

A unified Security Policy Management framework ensures consistent security controls and enforcement regardless of whether workloads run on-premises or in the cloud.

Which of the following is a benefit of using standardized architecture frameworks?

Answer: Consistency and reusability

Standardized architecture frameworks promote consistency across different projects and domains within an enterprise by providing common terminology, processes, and models. This consistency leads to increased reusability of architectural components, designs, and best practices, which in turn reduces development time, costs, and errors. It also facilitates better communication and understanding among stakeholders.

What is the key distinction between Enterprise Architecture (EA) and Solution Architecture (SA)?

Answer: EA provides the strategic context and framework for the entire organization, while SA focuses on designing specific solutions to address particular business problems within that context.

Enterprise Architecture operates at a strategic level, providing a holistic, long-term view of the organization's processes, information, and IT assets to guide future decisions. [18, 19] Solution Architecture is more tactical, focusing on designing and delivering a specific solution to a particular business problem, ensuring it aligns with the established enterprise architecture. [18, 19, 25]

An enterprise architect is conducting a stakeholder analysis for a new data analytics platform initiative. They identify the Chief Financial Officer (CFO) as a stakeholder with high power and high interest in the project's outcome. According to stakeholder management best practices, how should the architect engage the CFO?

Answer: Manage them closely by involving them in key decisions and providing regular, detailed updates.

Stakeholders with high power and high interest are key players who must be actively engaged and managed closely. The architect should involve them in critical decisions, seek their input, and maintain regular, targeted communication to ensure their expectations are met and their support is retained throughout the project lifecycle.

What does 'residual risk' mean in enterprise architecture risk management?

Answer: The risk that remains after all mitigation controls have been implemented

Residual risk is the level of risk that persists even after mitigation controls have been applied, and it must be formally accepted by the risk owner.

What is an Architecture Risk Register used for in enterprise architecture practice?

Answer: Documenting identified architectural risks, their likelihood, impact, and mitigation actions

An Architecture Risk Register captures identified risks to the architecture, including probability, impact, and planned mitigations.

In TOGAF's Architecture Roadmap terminology, what is a 'plateau'?

Answer: A relatively stable state of the enterprise architecture that exists at a specific point in time

A plateau in TOGAF represents a relatively stable state of the enterprise architecture at a particular point in time, existing either as the current baseline, an intermediate transition state, or the final target architecture.

How does governance influence architecture maturity?

Answer: Supports continuous improvement

Governance is essential for driving architecture maturity by establishing processes for continuous review, feedback, and refinement of the architecture. It ensures that lessons learned are incorporated, standards are updated, and the architecture evolves to meet changing business needs and technological advancements. This structured approach fosters ongoing development and improvement, rather than hindering productivity or collaboration.

A company's enterprise architecture mandates a 'cloud-first' strategy and has a preferred public cloud vendor to ensure data integration and security controls. The Marketing department wants to urgently purchase a specialized SaaS marketing automation tool that runs on a different, non-preferred cloud platform. What is the MOST appropriate initial action for the enterprise architect?

Answer: Facilitate a discussion with Marketing to understand the unique business capabilities the tool provides and assess the risks and costs of integrating a non-standard solution.

The primary role of the architect in this situation is to be a consultant and facilitator, bridging business needs with technology strategy. By first understanding the business driver and the specific capabilities the proposed tool offers, the architect can perform a proper assessment. This allows for an informed decision based on a balance of business value and architectural integrity, rather than making a purely technical or purely business-driven choice without due diligence.

Which security architecture model divides an enterprise network into zones with increasing levels of trust and access control?

Answer: Zero-trust architecture with micro-segmentation

Zero-trust architecture with micro-segmentation divides networks into isolated zones, requiring verification for every access request regardless of location.

What does the 'Zachman Framework' primarily focus on?

Answer: Enterprise architecture taxonomy

The Zachman Framework for Enterprise Architecture is primarily a taxonomy or classification scheme for organizing architectural artifacts. It provides a comprehensive, two-dimensional matrix that categorizes architectural descriptions from different perspectives (e.g., planner, owner, designer) and interrogatives (e.g., what, how, where, who, when, why). Its main goal is to provide a structured way to view and understand the enterprise.

What is the MAIN purpose of maintaining an Architecture Stakeholder Register?

Answer: To document all stakeholders, their interests, influence levels, and communication preferences for EA engagement

A Stakeholder Register is a living document that captures who the stakeholders are, what they care about, and how to engage them effectively.

A financial services company is undergoing a digital transformation. The Chief Technology Officer (CTO) is concerned about the scalability and security of the proposed architecture. The business analysts are focused on ensuring the new system supports all required business processes. According to TOGAF and general enterprise architecture principles, what is the primary mechanism for addressing these distinct stakeholder interests?

Answer: Creating specific Architecture Views tailored to each stakeholder group's concerns.

Architecture Views are created to address the specific concerns of different stakeholders. A view is a representation of the system from the perspective of a related set of concerns. For the CTO, a view focusing on technical and security aspects would be appropriate, while for business analysts, a business process-oriented view would be created. This separation ensures communication is effective and relevant to the audience.

Which technique is most effective for identifying dependencies between transition projects in an EA roadmap?

Answer: Dependency matrix or dependency mapping

A dependency matrix or dependency map explicitly shows relationships between transition projects, identifying which projects must be completed before others can begin, enabling proper sequencing.

During the initial planning phase of a new enterprise architecture program, the chief architect identifies significant resistance to change from several key business units. These units operate in silos and are hesitant to adopt cross-organizational standards. What is the most effective first step the architect should take to address this challenge?

Answer: Develop a detailed communication plan that clearly articulates the value proposition of the EA program to each stakeholder group.

Gaining buy-in and overcoming resistance to change are common challenges in EA implementation. The most effective initial step is to engage stakeholders and clearly communicate the value and benefits of the enterprise architecture program from their perspective. A well-crafted communication plan that addresses the specific concerns and goals of each business unit can build trust and foster collaboration, which is more effective long-term than enforcing compliance or escalating immediately.

What is the PRIMARY purpose of a threat modeling exercise in enterprise architecture?

Answer: To identify potential security threats, vulnerabilities, and corresponding mitigation strategies across the architecture

Threat modeling systematically identifies security threats and vulnerabilities so that mitigations can be designed into the architecture.

What is the purpose of a Business Transformation Readiness Assessment in EA transition planning?

Answer: To assess the organization's ability to successfully execute the planned transformation

A Business Transformation Readiness Assessment evaluates factors that affect the organization's ability to successfully execute the transformation, identifying risks and readiness gaps before transition begins.

What is the role of the Architecture Vision in EA transition planning?

Answer: To provide a high-level aspirational view that guides all detailed transition planning

The Architecture Vision provides a high-level, aspirational description of the desired future state, serving as the guiding framework that ensures all transition planning activities remain aligned to strategic objectives.
