CEA - Certified Enterprise Architect EA Tools and Repositories Questions and Answers — Questions and Answers
Question 1: An enterprise architect needs to perform an impact analysis to determine which business processes and applications will be affected by the planned decommissioning of a legacy server. Which of the following is the MOST critical prerequisite for an EA tool to effectively perform this analysis?
- A detailed list of all approved technology standards in the Standards Information Base.
- A repository with accurately modeled and linked relationships between technology, application, and business layers. (Correct answer)
- A comprehensive library of architectural patterns and reference models.
- Integration with the company's IT service management (ITSM) tool for real-time incident data.
Correct answer: A repository with accurately modeled and linked relationships between technology, application, and business layers.
Impact analysis fundamentally relies on the ability to trace dependencies across different architectural layers. An EA tool can only determine the impact of a change if the relationships (e.g., 'server hosts application,' 'application supports process') are explicitly modeled and stored in the repository.
Question 2: A company's EA team is struggling with inconsistent project architectures and the constant reinvention of common solutions. To promote reuse and accelerate development, they decide to create a collection of approved architectural patterns, design templates, and industry reference models. According to the TOGAF framework, where should these assets be stored?
- The Architecture Landscape
- The Governance Log
- The Reference Library (Correct answer)
- The Standards Information Base
Correct answer: The Reference Library
The TOGAF Reference Library is specifically designed to hold guidelines, templates, patterns, and other forms of reference material that can be used to accelerate the creation of new architectures.
Question 3: What is the primary purpose of an architecture metamodel within an Enterprise Architecture repository?
- To provide a real-time dashboard of project statuses and compliance metrics.
- To visualize the sequential flow of activities within key business processes.
- To store architectural diagrams created with external drawing tools.
- To define the types of architectural objects, their attributes, and their permissible relationships. (Correct answer)
Correct answer: To define the types of architectural objects, their attributes, and their permissible relationships.
The metamodel is the underlying schema or structure that defines what kind of information can be stored in the repository and how different pieces of information can relate to one another. It ensures consistency and provides the formal basis for analysis and modeling.
Question 4: Which of the following BEST describes the primary advantage of using a dedicated Enterprise Architecture tool over general-purpose diagramming software like Microsoft Visio?
- The enforcement of a structured metamodel and a central, queryable repository that enables traceability and analysis. (Correct answer)
- The ability to create more visually appealing diagrams with a wider range of colors and fonts.
- Significantly lower software licensing costs for the architecture team.
- The automatic generation of source code from architectural models.
Correct answer: The enforcement of a structured metamodel and a central, queryable repository that enables traceability and analysis.
While diagramming tools create static pictures, dedicated EA tools store architectural elements as objects in a repository with defined relationships. This structured approach is what enables powerful analysis, such as impact analysis, gap analysis, and traceability from strategy to technology, which is not possible with simple drawing tools.
Question 5: A newly appointed Chief Architect has discovered that architectural decisions, compliance reviews, and approved exceptions (dispensations) are poorly documented and difficult to track, leading to inconsistent governance. To rectify this, which component of the TOGAF Architecture Repository should be diligently maintained?
- Reference Library
- Governance Log (Correct answer)
- Architecture Landscape
- Standards Information Base
Correct answer: Governance Log
The Governance Log is the designated component within the TOGAF Architecture Repository for maintaining a record of all governance activities, including decisions, compliance reviews, and dispensation requests, ensuring a transparent and auditable trail.
Question 6: How does an Enterprise Architecture Repository primarily differ in purpose from a Configuration Management Database (CMDB)?
- An EA Repository is focused on future-state strategic planning, while a CMDB is focused on the real-time operational state of IT assets. (Correct answer)
- An EA Repository only stores logical and conceptual models, while a CMDB only stores information about physical hardware.
- An EA Repository is managed by business stakeholders, while a CMDB is managed exclusively by the network operations team.
- There is no significant difference; the terms are interchangeable for describing a central IT asset inventory.
Correct answer: An EA Repository is focused on future-state strategic planning, while a CMDB is focused on the real-time operational state of IT assets.
A CMDB's primary purpose is to support IT Service Management (ITSM) by providing an accurate account of the current operational state of configuration items. An EA Repository has a broader, more strategic scope, containing models of the baseline, transition, and target architectures, and linking technology to business strategy, which a CMDB does not.
