The Open Group OGEA-102 Dumps Questions Answers

According to the TOGAF standard, the Target Architecture is the description of a future state of the architecture being developed for an organization. It should be aligned with the Architecture Vision, Principles, and Requirements that have been agreed with the stakeholders. To address the incompatibilities between key stakeholder preferences, the TOGAF standard recommends creating and evaluating multiple alternative Target Architectures that meet different sets of criteria. These criteria should reflect the value preferences and priorities of the stakeholders, as well as the business drivers and objectives. The alternative Target Architectures should be illustrated using a set of architecture views that show the impact of each alternative on the business, data, application, and technology domains. The impact on planned projects should also be identified and analyzed. The strengths and weaknesses of each alternative should be understood and documented. A formal stakeholder review should then be conducted to decide which alternative is the most fit for purpose and should be moved forward with. The funding required for implementing the chosen alternative should also be determined and secured. References:

You are asked to identify the most relevant Architecture Principles, besides Business Continuity, that apply to a rapid merger, where:

Back-office and store management systems will be consolidated

Duplicate applications will be eliminated

Innovation must remain fast

Customer experience must remain uninterrupted

Combined enterprise value is the priority

TOGAF’s example Architecture Principles include four main categories:

Business Principles

Data Principles

Application Principles

Technology Principles

Option D contains the principles that best support the specific needs of the merger as described.

✔ Why Option D is correct

1. Service Orientation (Business Principle)

This principle states that architecture should be organized around services, enabling flexibility, loose coupling, and ease of integration.

For the merger:

Integrating two companies’ store systems, mobile apps, and inventory platforms requires modular, interoperable services.

Service orientation directly supports the requirement that innovation must not slow down.

It allows systems to be merged with minimal disruption.

This principle supports fast integration + ongoing innovation — exactly what stakeholders demand.

2. Maximize Benefit to the Enterprise (Business Principle)

This principle ensures decisions are made from an enterprise-wide (not departmental or local) perspective.

In the scenario:

Two companies are merging.

Decisions must prioritize combined enterprise value, not local optimizations by either company.

System consolidation and elimination of duplicates requires an enterprise-first mindset.

This principle aligns perfectly with a merger that aims to unify operations and reduce redundancy.

3. Common Use Applications (Application Principle)

This is one of the MOST relevant principles in any merger.

TOGAF defines this principle as:

“Applications should be shared across the enterprise and not duplicated.”

In the scenario:

Back-office systems and store management tools must be consolidated.

Duplicate applications are explicitly to be reduced.

One main system will be used across stores.

This principle directly matches the merger ' s objectives.

✔ Summary

Option D contains the three principles that best support:

A major merger

System consolidation

Reduction of duplication

Enterprise-wide benefit

Flexible, service-oriented integration

Continued innovation

Therefore, Option D is the most appropriate selection according to TOGAF’s example Architecture Principles.

In this scenario, the CTO has not purchased cyber-insurance, the CSO is concerned about increased DDoS risk, and YOU (the EA) are asked “to describe the steps you would take to strengthen the current architecture to improve data protection.”

Because the company follows the TOGAF standard and uses an iterative ADM cycle, the correct response must:

Start with the risk/continuity concern

Use the formal TOGAF change management process

Lead to a Request for Architecture Work

Initiate a new ADM cycle to update the architecture properly

Ensure Architecture Board governance

Option B is the only answer that matches TOGAF’s required process.

✔ Why Option B is correct (TOGAF-aligned)

Option B follows TOGAF’s Architecture Change Management (Phase H) process:

Assess the business continuity requirements– Correct: Phase H requires evaluating change triggers such as new risks, threats, or incidents.– DDoS risk → business continuity concern → legitimate architecture change trigger.

Analyze the current architecture for gaps– Correct: TOGAF Phase H requires assessing whether the current baseline architecture can support required resilience.

Create a formal Change Request– Exactly correct: Phase H outputs Architecture Change Requests (ACRs) for significant changes.– ACR includes description, rationale, and impact (in this case: resilience, continuity, and data protection).

Architecture Board reviews/approves the change request– Correct: All major architecture changes must go through Architecture Governance.

Create a new Request for Architecture Work (RFAW)– Required when the change is significant and needs a new ADM cycle.– Strengthening data protection and business continuity DEFINITELY qualifies as a major change.

Begin a new ADM cycle to implement the changes– Perfectly aligned with TOGAF’s iterative approach:Business continuity → update Technology Architecture → updated security patterns → updated Target Architecture.

This is exactly the TOGAF-prescribed method to strengthen an architecture when significant new risks appear.

Therefore, Option B is the correct and TOGAF-compliant answer.

✘ Why the other options are incorrect

A – Not TOGAF-aligned

Starts with vendors and simulations (not TOGAF-first steps).

No mention of Architecture Board or Change Management.

No Request for Architecture Work.

Gap analysis alone is not the first step for significant architectural risk.

C – Too narrow and skips TOGAF governance

Jumps straight to modifying the Technology Architecture baseline.

No Change Request, no RFAW, no ADM cycle initiation.

Recommends a solution (“DDoS mitigation at infrastructure level”) before architectural assessment.

D – Misuses Architecture Compliance Review

Architecture Compliance Reviews check conformity to an existing architecture—not evaluate new risks or design resilience enhancements.

A compliance review is not the correct first step for addressing new threats.
