Certified Master Architect (CMA) — Questions and Answers

Question 1: When decomposing a complex solution into architecture building blocks, which principle should guide the granularity of decomposition?

Each building block must map 1:1 to a single code module
Granularity should match the organizational team structure exactly
All blocks must be deployable as independent microservices
Decompose until each block has a single, well-defined responsibility (Correct answer)

Correct answer: Decompose until each block has a single, well-defined responsibility

The Single Responsibility Principle guides decomposition by ensuring each building block has one clear purpose, reducing coupling and improving replaceability.

Question 2: A financial services application requires a complete and immutable audit trail of all transactions. For compliance and analytical purposes, the business needs the ability to reconstruct the state of any account at any point in history. Simply storing the current state of the data is insufficient. Which pattern best addresses this requirement?

Snapshotting
Stateful Service
Event Sourcing (Correct answer)
Transactional Outbox

Correct answer: Event Sourcing

Event Sourcing is a pattern where all changes to an application's state are stored as a sequence of events. This append-only log of events provides a full audit trail and allows for the reconstruction of an entity's state at any point in time by replaying the events. This is ideal for systems requiring strong audit capabilities.

Question 3: A 'panopticon' spatial arrangement, as described by Jeremy Bentham and theorized by Foucault, is MOST applicable to which contemporary building type?

A correctional facility or institutional building requiring centralized surveillance (Correct answer)
A public library with open stacks
A hospital designed for infection control
A shopping mall with radial circulation

Correct answer: A correctional facility or institutional building requiring centralized surveillance

The panopticon places a central observation point from which all cells or zones can be monitored simultaneously, a model most directly applied to correctional and institutional facilities.

Question 4: In a data warehouse architecture, what distinguishes an Operational Data Store (ODS) from a data warehouse?

An ODS is read-only while a data warehouse supports write operations
An ODS is updated in near real-time while a data warehouse contains historical snapshots (Correct answer)
An ODS stores historical data while a data warehouse stores only current data
An ODS uses dimensional modeling while a data warehouse uses ER modeling

Correct answer: An ODS is updated in near real-time while a data warehouse contains historical snapshots

An ODS is designed for near real-time operational reporting with current data, while a data warehouse integrates historical data across subjects for analytical and strategic reporting.

Question 5: Which technique is used to elicit and refine quality attribute scenarios from stakeholders during architecture evaluation?

Glulam beams use structural adhesives such as phenol-resorcinol formaldehyde (PRF) or melamine-urea formaldehyde (MUF) to bond laminations.

Question 11: An international bank is selecting a primary public cloud provider. All major providers meet the functional and performance requirements. However, the bank operates in several countries with strict data sovereignty laws (e.g., GDPR) that mandate certain types of customer data must remain within national borders. In this context, which platform attribute becomes the most critical non-functional differentiator for the selection process?

The breadth and maturity of the provider's AI and machine learning services.
The ease of integration with the bank's existing on-premise DevOps toolchain.
The provider's consumption-based pricing model and potential for volume discounts.
The provider's global network of data center regions and their specific in-country presence. (Correct answer)

Correct answer: The provider's global network of data center regions and their specific in-country presence.

For an international bank, regulatory compliance is non-negotiable. Data sovereignty laws require customer data to be stored and processed within specific geographic borders. Therefore, the cloud provider's ability to guarantee data residency in specific countries through their regional data centers is the most critical deciding factor, overriding other considerations like advanced services or pricing models.

Question 12: A master architect is leading a post-occupancy evaluation (POE) for a completed building. What is the primary professional benefit of this activity?

Satisfying construction warranty requirements
Identifying performance gaps between design intent and actual building performance to improve future design decisions (Correct answer)
Generating additional fee from the owner

A general statement of a system's desired behavior
A high-level category of system properties
A pattern for organizing system components
A specific, measurable scenario tied to a particular system (Correct answer)

Correct answer: A specific, measurable scenario tied to a particular system

A concrete scenario specifies actual values and conditions for a particular system, making it directly usable in architecture evaluation.

Question 24: A project is experiencing scope creep that threatens the schedule. Which project management technique helps control this most effectively?

Compressing the schedule by fast-tracking
Reducing quality standards to meet the deadline
Adding staff to absorb additional scope
Implementing a formal change control process (Correct answer)

Correct answer: Implementing a formal change control process

A formal change control process ensures all scope additions are evaluated for cost and schedule impact before authorization, preventing uncontrolled growth.

Question 25: The 'Means of Egress' under the IBC consists of three components. Which of the following correctly lists all three?

Exit access, exit corridor, and building exit
Exit access, exit, and exit discharge (Correct answer)
Corridor, exit stair, and exit door
Lobby, elevator lobby, and exit stair

Correct answer: Exit access, exit, and exit discharge

The three components of a means of egress are exit access (path to the exit), exit (protected path), and exit discharge (path from the exit to the public way).

Question 26: In a technology feasibility assessment for a new practice area, which factor is MOST critical to evaluate first?

The vendor's social media following
The gap between current staff skills and those required by the new technology (Correct answer)
Whether competing firms already use the technology
The color scheme of the software's user interface

Correct answer: The gap between current staff skills and those required by the new technology
