Statements 1 and 3 about architecture partitioning are correct. Architecture partitioning is the technique of dividing an architecture into smaller and more manageable parts that can be developed, maintained, and governed independently. Partitions are used to simplify the management of the Enterprise Architecture and to enable different teams to work on different elements of the architecture at the same time. Partitions are not equivalent to architecture levels, which are different degrees of abstraction or detail in an architecture. Partitions do not necessarily reflect the organization's structure, which may change over time or differ from the architecture's scope and boundaries. Reference: The TOGAF Standard | The Open Group Website, Section 2.5 Architecture Partitioning.

According to the TOGAF standard, the deliverables that match the descriptions are as follows:

1 Architecture Principles: These are general rules and guidelines, intended to be enduring and seldom amended, that inform and support the way in which an organization sets about fulfilling its mission1.They reflect a level of consensus among the various elements of the enterprise, and form the basis for making future IT decisions1.

2 Architecture Contracts: These are the joint agreements between development partners and sponsors on the deliverables, quality, and fitness-for-purpose of an architecture2.They are used to ensure that the architecture is implemented and governed according to the agreed-upon specifications and standards2.

3 Request for Architecture Work: This is a document that is sent from the sponsoring organization to the architecture organization to trigger the start of an architecture development cycle3.It defines the scope, schedule, budget, deliverables, and stakeholders of the architecture project3.

4 Architecture Requirements Specification: This is a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture4.It defines the requirements for each architecture domain, as well as the relationships and dependencies among them4.

The Implementation Governance Model is a framework that defines the roles, responsibilities, processes, and standards for governing the implementation of the target architecture. It ensures that a project transitioning into implementation also smoothly transitions into appropriate Architecture Governance, which is the practice of ensuring compliance with the enterprise architecture and its principles, standards, and goals.The Implementation Governance Model is part of the Implementation and Migration Plan, which is the output of Phase F: Migration Planning of the Architecture Development Method (ADM)12Reference:1: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 21: Phase F: Migration Planning2: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 50: Architecture Governance

In the ADM documents which are under development and have not undergone any formal review and approval process are called ''draft''. This indicates that they are subject to change and refinement as the architecture development progresses. Reference: The TOGAF Standard | The Open Group Website, Section 4.2.5 Architecture Deliverables.

* Phase A: Architecture Vision

o Develop a high-level aspirational vision of the capabilities and business value to be delivered as a result of the proposed Enterprise Architecture

o Define the scope and boundaries of the architecture engagement

o Identify the key stakeholders and their concerns and expectations

o Define the Architecture Vision statement and the Architecture Definition Document

o Obtain approval and commitment from the sponsors and stakeholders

* Phase B: Business Architecture

o Develop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals

o Define the Baseline Business Architecture, if not available

o Perform a gap analysis between the Baseline and Target Business Architectures

o Define candidate roadmap components for the Business Architecture

o Resolve impacts across the Architecture Landscape

* Phase C: Information Systems Architecture

o Develop the Target Data Architecture that enables the Business Architecture and the Architecture Vision

o Develop the Target Application Architecture that supports the Business Architecture and the Architecture Vision

o Define the Baseline Data and Application Architectures, if not available

o Perform a gap analysis between the Baseline and Target Data and Application Architectures

o Define candidate roadmap components for the Information Systems Architecture

o Resolve impacts across the Architecture Landscape

* Phase D: Technology Architecture

o Develop the Target Technology Architecture that enables the Information Systems Architecture and the Architecture Vision

o Define the Baseline Technology Architecture, if not available

o Perform a gap analysis between the Baseline and Target Technology Architectures

o Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Technology Architectures

o Resolve impacts across the Architecture Landscape

Therefore, the correct matching of the objectives and the phases is:

* 1C: Develop the Target Data Architecture that enables the Business Architecture and the Architecture Vision

* 2B: Develop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals

* 3A: Develop a high-level aspirational vision of the capabilities and business value to be delivered as a result of the proposed Enterprise Architecture

* 4D: Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Technology Architectures
