NEW QUESTION # 100
The search function associated with a document management store is failing to return known artefacts. This is due to a failure of:
Answer: B
Explanation:
A document-management search function depends heavily on metadata to identify, index, classify, and retrieve stored content. If known artefacts exist in the repository but cannot be found through search, inadequate or incorrectly maintained metadata is the most direct explanation.
DAMA-DMBOK2 distinguishes document content from the metadata that describes it. Typical descriptive metadata includes title, author, subject, keywords, document type, creation date, classification, and other characteristics used by retrieval mechanisms. Administrative and structural metadata may additionally support lifecycle management, versioning, access control, and relationships among document components. Without sufficiently accurate and complete metadata, the repository may physically contain a document while users remain unable to discover it.
This is also a Data Quality problem. Metadata itself is data and must satisfy quality expectations such as completeness, validity, consistency, and accuracy. A missing subject classification, incorrect document type, or inconsistent keyword convention can directly reduce findability.
Public access is neither required nor desirable for all documents, especially where confidential information exists. Business Intelligence is unrelated to basic document discovery, and Data Quality metrics alone do not make a document searchable unless the underlying metadata is correctly populated.

NEW QUESTION # 101
A DMZ is bordered by 2 firewalls. These are between the DMZ and the:
Answer: E
Explanation:
A Demilitarized Zone (DMZ) is a controlled network segment positioned between an organization's trusted internal environment and an external, untrusted environment such as the Internet. In the classic architecture described in DAMA-DMBOK2, the DMZ is separated from the Internet by an external firewall and from internal organizational systems by another firewall. Therefore, the correct answer is Internet and internal systems.
DMBOK2 describes the DMZ as an area on the organization's perimeter, with firewall protection separating it from the organization and firewall protection between the DMZ and the Internet. It is commonly used for services or transient data exchanges that must interact with external parties without providing direct access to internal systems.
This arrangement implements defense in depth. Public-facing services can operate in the DMZ while internal databases and sensitive systems remain behind an additional security boundary. A compromise of a DMZ host should therefore not automatically expose the internal network.
For Data Quality, security architecture is relevant because unauthorized modification or corruption can compromise integrity and accuracy. Protecting interfaces and repositories supports trustworthy data processing as well as confidentiality and availability.

NEW QUESTION # 102
What is one of the Data Architecture artifacts which are usually captured within development projects, and then standardised and managed by data architects?
Answer: B
Explanation:
The correct answer is Data models. DAMA-DMBOK2 explicitly explains that data models and other Data Architecture artifacts are commonly created or captured within development projects and are subsequently standardized and managed by Data Architects.
Development projects routinely produce conceptual, logical, and physical representations of the data required by a solution. If each project develops those structures independently without architectural review, inconsistent terminology, duplicated entities, conflicting definitions, and incompatible relationship structures can accumulate across the enterprise. Data Architects therefore review project models, reconcile them with enterprise standards, and identify structures suitable for reuse.
An Enterprise Data Model is itself an important architectural artifact, but the wording of the question refers specifically to artifacts typically generated in individual development projects and later standardized. The DMBOK2 passage uses data models in precisely that context.
This process has a direct Data Quality benefit. Standardized models improve consistency of definitions, domains, keys, relationships, and constraints. They also provide metadata from which integrity, uniqueness, validity, and completeness rules can be derived.
Reference Topics: DAMA-DMBOK2 Chapter 4 - Data Architecture; Architectural Artifacts; Development Projects; Chapter 5 - Data Modeling and Design; Chapter 13 - Consistency and Integrity.
NEW QUESTION # 103
What are the types of models that are modelled in data models?
Answer: E
Explanation:
DAMA-DMBOK2 identifies four principal types of data that may be represented in data models: Category Information, Resource Information, Business Event Information, and Detail Transaction Information. Because options A, B, C and E are all legitimate categories, All of these is correct.
Category information classifies things-for example, classifying customers by market segment or products by size or colour. Resource information represents business resources required for operations, including entities such as Customer, Product, Supplier, Facility and Account. These resource entities frequently overlap strongly with Master and Reference Data Management.
Business event information records events created during operational processes, such as orders, invoices or withdrawals. Detail transaction information represents highly granular observations, including point-of-sale records, clickstream data, social-media interactions, sensor outputs and other high-volume events.
This classification matters to Data Quality because quality controls must reflect the semantics and lifecycle of the data being evaluated. Reference and master data require strong uniqueness, definition and consistency controls; event data require integrity and timeliness; high-volume detailed data often require automated profiling and statistical monitoring.
Data models also generate important metadata-definitions, relationships, domains and constraints-which becomes the basis for measurable Data Quality rules.

NEW QUESTION # 104
A dashboard reports that Customer_Email Completeness is 98.5%, while the approved threshold is 99.5%.
What should the 98.5% figure be interpreted as?
Answer: B
Explanation:
The 98.5% value is a measured Data Quality result, and because it is below the approved 99.5% threshold, it represents a threshold breach.
A Data Quality metric quantifies observed performance. A threshold establishes the level of performance the business has agreed is acceptable. These should not be confused. The metric answers how are we performing?; the threshold answers is that performance acceptable?
The 98.5% completeness result says nothing about whether the populated email addresses are accurate. A field can achieve high completeness while containing incorrect or invalid values. Other rules may therefore be required for email syntax, uniqueness, deliverability, or factual correctness.
A threshold breach should trigger a predefined response appropriate to the criticality of the data. This may involve investigation, escalation, remediation, trend review, or root-cause analysis.
Metrics, calculation logic, measurement population, thresholds, ownership, and escalation rules should be documented as metadata so dashboard results remain interpretable and reproducible.
DAMA's framework explicitly places metrics, error detection, cleansing, and quality management within Data Quality Management.
